This Way to the Egress

Just as the doomsday clock on the cover of  'Atomic Scientist' magazine indicates the proximity to the precipice so the reports of shenanigans in HD retail indicate the level of desperation of those to be 'left behind'.  The deceptions, bait and switches and out right lies are everywhere waiting to lure in the innocent and uninitiated.



The 10 worst HDTV, scams, lies and ripoffs.



http://hdguru.com/the-10-worst-hdtv-scams-lies-and-video-ripoffs/



This article does have some faults, in particular a general misunderstanding of HDMI and the rules of HDCP but is right on with Fake HD Cable and Satellite Channels (number 9) and Deep Color (part of the 1.3 spec and number 7 on the list).   



Deep color is currently nothing more then hype and promise with no source devices capable of producing deep color content.  Yes, you will be ready when and IF this is ever utilized by content producers, yet as Pee Wee Herman said- 'You have a big but there...'



Fake HD channels are just dishonest, yet every cable and satellite provider has a few channels they include in their HD package which are in reality SD widescreen content.  Phil Swann of  www.TVPredictions.com  has commented on this at



HDTV: Networks Should Stop Stretching the Truth



http://www.tvpredictions.com/forum/comments.php?y=08&m=04&entry=entry080421-102055



Why would major broadcast and cable providers deliberately try to fool the average HD viewer? Because 



1. The true HD content is STILL not there. Well at least in the volume to feed a constant broadcast schedule.



2. Cable and Satellite providers have a serious issue of bandwidth. Consumers are demanding two main services, HD content and a plethora of choices. Without compressing the digital data - thus losing some detail- it is just not possible for these providers to deliver both true HD content and 1000 channels. (Thus proving Bruce Springsteen was right all along). 



MSNBC provided an interesting article on this subject:



Cable TV under fire for degrading HD quality



http://www.msnbc.msn.com/id/24238071/



The Slashdot folks also took Comcast to task on this



http://slashdot.org/article.pl?sid=08/03/30/2113218&from=rss





And that promise of 1080p? All those sets selling by prominently listing a 1080p capable spec, well your going to have to wait awhile



Tandberg CEO: 1080p HDTV In 3 Years



http://www.tvpredictions.com/1080p041408.htm



Still think this is just a few over eager manufacturers jostling for market presence?  Um, not so much, major retailers are trying to dump non HD units on unsuspecting consumers:



Retailers Fined $4M for Improper Labels on TVs



http://www.npr.org/templates/story/story.php?storyId=89551875&ft=1&f=1019



Then there are the stacks of portable TV these same retailers are still selling with no warning that in only few short months they will be as useless as wax cylinders.



Don't buy a portable TV this year

There is also the very real possibility that millions will be left without any form of TV reception and no, we are not just talking about those living in the vast stretches of Montana- NYC and

Boston

top the list:

http://www.tvpredictions.com/centris041008.htm



Into this possible gap comes the federal government and its DTV coupon program to help those of lesser incomes purchase converter boxes at discount -(and thus extend the life of their non HD\DTV sets). All is well you think, Ha!



Scammers Exploit DTV Coupon Program



http://tech.slashdot.org/article.pl?sid=08/04/08/2245248&from=rss



The title of this post comes from the semi anecdotal story about PT Barnum’s infamous '

American

Museum

'. The premise of the story is that the museum was so popular that folks would linger too long, thereby making it difficult to get others in and impacting the total days take. P.T being the shrewd showman posted signs throughout the museum which read 'This Way to the Egress!', knowing full well most people would not know that Egress meant exit. It is said that many a visitor would follow the signs out a door and down a covered stairway to an empty courtyard. The door just exited closed and locked behind them, thus making another ticket charge the only way to get back in.  Many people would complain that they never did get to see the Egress!

Heisenberg Exits Forthwith, Whereabouts Uncertain

There are many dimensions to our universe, some say it is fixed at 4 or 5, others state a 12 dimensional universe actually makes the math in a grand unified theory nearly work.  A good entry level book on this subject is Hyperspace by Dr. Michio Kaku - http://www.amazon.com/Hyperspace-Scientific-Odyssey-Parallel-Universes/dp/0385477058 .



Space and Time are funny things, interrelated and so very separate. Into this fray comes the company Alien which has announced a product which can tell the speed and location of a tagged item. The article



RFID reader can now identify velocity, position of tags



http://www.news.com/8301-10784_3-9917346-7.html?part=rss&subj=news&tag=2547-1_3-0-20



discusses possible uses for airport and military cargo. I see the possibility of using this technology for environment automation. Many green initiatives require occupancy sensing to minimize energy use in unused rooms. Most of these 'people counters' are microwave sensors which only indicate movement or,when mounted to a door frame, numbers in and out of a room. This is a highly inefficient method as the timing between sensing a presence and sensing no presence is awkwardly long.  Imagine using this Alien RFID product to sense presence, speed of the person and by extension direction - to intelligently decide just how bright to make each room traveled through and prepare the next room to be entered.   This is a much more efficient method where the lights are kept on only to ensure an individual can see enough to travel through safely, no time delay.  This is only one possible application, silly versions can have doors open slower or faster depending on your travel speed - thus helping avoid a crash into a half open\closed door.



Now, does this make the   CERN ATLAS particle accelerator  unneeded?

HDMI - Nitrate Free?

HDMI is a funny thing. To those of  who cut our teeth crimping copper BNC or soldering XLR's trusting in a cable we cannot make ourselves presents a quandary.   The first time I looked into an HDMI cable I was left with questions similar to those often asked about hot dogs - 'Just what is in that thing?'.


A number of questions still befuddle installers daily



  • How long can I run an HDMI cable -(answer: it depends on the gauge and quality of cable not necessarily a predefined length limit)
  • What effect does HDCP have on my connections -( answer: its presence turns off component outputs  \ inputs and does have bandwidth considerations, which may effect usable cable length).
  • Which devices support deep color ? -(a few, maybe).


In an apparent answer to our questions I have been receiving a plethora of newsletter and articles on just such subjects  lately:


CEpro: 3 ways to improve HDMI http://www.cepro.com/article/3_ways_to_improve_hdmi/?utm_source=CEPWeekly&utm_medium=email


HDMI.org newletter: What do speed ratings on HDMI cables mean? http://hosted.verticalresponse.com/170134/ceb1d060a1/132000973/9ac1526c60/



HDMI.org also has a great  set of  webinars (live or self guided)http://hdmi.org/learningcenter/installer_training.aspx

MMMMMax Head- HeadRoom? No, its WiMax -Stutter Optional.

Those who have been long time readers of this blog will know my fascination with Sprint's WiMax plans.  True mobile broadband has remarkable potential not just for content on the go but to provide seamless content which can travel from mobile to home theater with the click of a docking station.



Sprint had some issues garnering any real productive support from partnerships, all while declaring WiMax a true 4G mobile standard.  The declaration irked the wireless telecom industry standards organization who would only comment that WiMax was to be viewed as a building block not and end unto itself for 4G.



Then the news stalled for awhile.



In the last week or so a number of article have started to show a revised plan and possible industry support.  There is also talk of spinning off the WiMax into a separate company. 



On the positive side there is the showing of a WiMax enabled Tablet PC from Nokia -(due out this summer)



Nokia Tablet to Use Sprint WiMax Network



http://www.nytimes.com/aponline/technology/AP-Wireless-Show-WiMax.html?ex=1364875200&en=fc218dd7d0ea2e58&ei=5088&partner=rssnyt&emc=rss



Then there are the partnerships, however limited - Comcast in is $1 billion while TW is at $500 million-which are viable as they have a great deal to gain if the plan is a success. 



Comcast and Time Warner to Bankroll WiMax Joint Venture



http://www.news.com/8301-10784_3-9903411-7.html?part=rss&subj=news&tag=2547-1_3-0-20



Cable company interest may not be the first entities one would think to partner with a wireless phone system but further thought shows it to be a great tactical move if it succeeds.  Phone and Cable companies have been making in roads into the others main market for the last few years-(cable offering VoIP while phone companies now offer cable like media content on their land lines).  Cable companies see WiMax -(as well as the 700MHz band just sold off and the 'White Spaces' proposals) as taking the fight back to the wired Telecoms.  The hope is to establish WiMax into what the now failed Muni-Fi system promised but failed to deliver though less then stellar data rates and some community resistance.  On its face WiMax broadband opens the market for a host of devices -iphone like- whose central function is Internet access with voice as a secondary feature. What has only been hinted at is the ability to use this backbone to provide real-time video services; this is what the cable companies want.   Imagine having access to the baseball game whilst on the bus, subway or at the Cafe.  Add to this the ability to pull up Internet for stats, twitter chats or your fantasy baseball team progress, all at wired broadband speed.  In a cradle to grave metaphor the WiMax partners envision you taking this real time content all the way home and continuing to use their service as your primary content provider.  In a system concept similar to wireless video and the 802.11n standard, the hope is for the user to take their WiMax device and connect it to a monitor when home - never missing moment of the show and never having to switch to a land line provider.



And then the realities of rolling an actual system\devices brings us back to the daily grind:



Sprint Delays WiMax Roll-out, Again



http://blog.wired.com/business/2008/04/sprints-xohm-de.htm



Plans are now for a summer 08 roll out but by delaying the commercial start this will allow for the hype generated by AT&T and Verizon to begin to influence corporate planners.



If any thing the WiMax concept and Mobile broadband interest rides along side the rise in demand  for mobile video content. I have long stated the Phil Swann Inverse Square Rule, Every time Mr. Swann -or someone on on his TV predictions forum- wonder aloud why anyone would want to view content on their iPhone type screens; the number of  consumers clamoring for it doubles.

Eh?! Whats that you say? It sounds like a barking dog, or Caruso Singing. I am not quite sure.

So, I get this new found energy and desire to re- start up the blog, and things are going well.  Then BANG I catch the nasty cold that has been making the rounds between my 2 1/2 year old, my 9 month old and my Wife.  I am a bit bleary eyed and my nose is running like a leaky spout. 'I love it when a plan comes together'.



While my biting repartee is muted I did find some interesting items of  Tech Arcane -(dammit, I still cannot get the Jerry Reed song  'East Bound and Down' '...cause the boys are thirsty in Atlanta and there's beer in texarcana',  song outta my head).  What this really shows is that I watched the first Smokey and the Bandit movie way too many times as a kid. SATB may very well be where I caught a hook into the then 'hillbilly sounds' of country. I soon found better refuge in the likes of Hank Williams.  Then Rock n' Roll took hold O' my soul, but of the pure guitar pickin and twangy harmonies made their way back to me in the likes of X, Wilco, Lucero and the Rock-a-Billy \ Punk-a- Billy of The Cramps, The Reverend Horton Heat, Slick Pelt  and garage -billy bands like the Stumbleweeds.   Technologically we live in gilded age of musical access where many of us only have the slightest inkling as to where it all started.



Edison is heralded by the mass culture as the inventor of recording.  He certainly had his hand in making a mass market device which allowed for the music to come to you rather then having to go out and see it live. (it is interesting to read archival articles on how stunning people thought the sound was, how true to life , and also to hear the naysayers declare it did no justice to being in the music hall to hear first hand.   The modern equivalents have allowed us mock the over reaching comments of yesteryear but in reality our grandchildren will say the same of us).  Yet, Edison apparently is not the first to conceive of and operate a recording device.  I found  an interesting article on the NPR site about  much earlier French devices which only recently could be listened to.  The article describes and has an audio sample of an 1857 recording of a French folk song:



Sound Recording Predates Edison Phonograph



http://www.npr.org/templates/story/story.php?storyId=89148959&ft=1&f=1019



I also found a nifty little article and video of a Japanese learning toy manufacture who made a limited quantity of Edison phonograph toys.  The Toy will record and playback from a standard plastic cup:

Avast! I find Ye Returning from the Isle of Lost Friends

When T6 started out as a in house email - newsletter I wanted a memorable name for it to both amuse my associates and make it memorable.  Being a Lit major in college (focus on American poetry of the 19th century) I am a fan of alliteration. I also was an avid reader of Mark Schubin's Monday Morning Memo.  When Mark moved his newsletter to another venue I lost touch but named T6 as a homage to the memo. 



Truth is, if i really went looking I would have found him but I did not. Out of the blue I decided to contact him with a question.  Mark lead me to his great Podcast site, The Schubin Report http://www.theschubinreport.com/.  The podcasts are slick presentations where Mark discusses High Definition news.   



I have added his link to my blog under the inspired Tech Links' Section.  (Currently on the left hand side of the Blog).  Check him out - I'll wager that you will anticipate his next podcast after the first listen.

Its Just That Once You Accept One Into Your Neighborhood, They All Want In

If you have been paying any attention to the analog frequency sell off conducted by the FCC, you will undoubtedly have noticed that Google is just moderately interested in the proceedings.



Google has for some time been working on getting itinerant device access to what is commonly known in the industry as RF white spaces. White Space refers to the valleys which exist between the Color, Picture and Sound spikes of analog television signals.  (Typically an analog TV signal has a separate modulated RF signal for the Color, Picture and Sound, all three are received by the television and processed to complete the signal). 



White Spaces are typically where the FCC allowed the use of itinerant low power RF transmitters for wireless microphones and Intercom systems.  While TV broadcast signals are very powerful (typically 50k watts) for the most part you could hide a great deal of microphones in between the spikes. If you lived in the sticks, or just outside a major urban area, you could rely on finding some portion of the spectrum which was free of a TV channel.  In heavily saturated urban areas - such as NYC- you relied on proximity effect hoping that as the microphone would be the stronger signal - locally- to the receiver.  For the most part this usually worked out very well with only the occasional interference and then the dynamic compression circuits would kick in, minimizing the audience impact. In sections of the City, like Broadway, you also have to contend with wireless systems in adjacent theaters. The logistics are remarkable.



To this mix Google wants to add the mobile communications devices which would use access points placed within the remaining white space areas to facilitate Wifi\Wimax type  'local access'. The concern of many in the commercial market is the possible havoc this could causes to existing system and make overly complicated new installs. Google's answer is to institute a device awareness protocol which would recognize that at a device or devices are already in use and not transmit until clear. I would surmise that the withholding of transmission would only be until it could find a time slot to transmit.  Live audio is a continuous stream - whether analog or digitized in the microphone - and does not allow for a momentary pause to allow other devices access to the frequency.   As a compromise a few others have offered up a fixed licensing scheme but it has been met with minimal enthusiasm. As I no longer work in the event staging world this is a minimal concern, but for corporate\commercial installers this is an issue to keep a close eye on.



Two good articles which cover this story well are at



CTIA urges FCC to license -- and auction -- TV white spaces



http://www.rcrnews.com/apps/pbcs.dll/article?AID=/20080327/FREE/120719096/1007

http://www.news.com/8301-10784_3-9901747-7.html?part=rss&subj=news&tag=2547-1_3-0-20



Inevitably the spectrum will be auctioned off and utilized for a mass consumer set of services.  You may have to become accustomed to lower quality audio from you live performances or see the reemergence of old school wired, hands free microphones.  okay that was a joke, sort of. It is clear that the tiny market of wireless audio systems will be overwhelmed by the tsunami of consumer traffic. 



I touched on this in Issue 14 Volume 3 of the old newsletter (July of 07)

Can I Has a New Bogeyman?

Trolling around tonight I found an article on a town rejecting a distributed Wifi system based on fears of  health risks from the RF. 



WiFi Fear Kills Free Local WiFi Plan -   http://techdirt.com/articles/20080325/002149639.shtml



The article provides only  a snarky commentary with no background information nor links to an official news story, I was able to find a number of sites corroborating the story but only one had any real credentials - The San Franscisco Chronicle:  http://news.sfgate.com/cgi-bin/article.cgi?f=/n/a/2008/03/24/state/n100739D20.DTL



I had a bit to say about this type of hysteria back in  October 07. http://tuckerstuesday.typepad.com/tuckerstuesday/2007/10/index.html



The communities concern did not center on a relatively high power Muni-fi system but a small distributed access point setup.  The system proposed would have less radiated power then I am exposed to daily at my work -(where we have no less then 10 wifi system running  constantly).



Why do humans need to find new bogeymen whose threat to humanity becomes more ominous with each iteration ?  This is a question  which Micheal Shermer could examine far more eloquently then I;  the reality is no medical proof has been offered up after nearly 25+ years of medical studies on High Power lines, proximity to transmission towers, etc.  The unstated message here is that not only will the Internet rot your brain, it will cause a tumor as well.



You take The Low Byte, I'll Take the High Byte and I'll get to HD streaming before Ye

There seems to be a lot of chatter on Bit Torrent lately and most of it is positive!



Recently the Canadian Broadcasting Corporation, Canada's public broadcaster, aired the finale of Canada's Next Great Prime Minister which also included the release of the entire show in high resolution, NO copy protection via Bit Torrent.



The entire Article is at http://news.bbc.co.uk/1/hi/technology/7312460.stm



I have also noticed a number of new products which publicly include Bit Torrent mechanisms , many include the Bit Torrent branding up front.  The latest I have come across is the Myka



The source article from endgadget



http://www.engadget.com/2008/03/21/myka-sneaks-bittorrent-into-the-living-room/



Then there is the rancors saber rattling of the ISP's who are pushing hard to end Internet(s) neutrality and attack the use of unregulated ' bandwidth hogs' such as Bit Torrent. These same companies then turn around and offer similar services at a premium. 



Business Week has a very interesting article on this including a breakdown of the players and what each can possibly gain or lose.



http://www.businessweek.com/technology/content/mar2008/tc20080321_685942.htm?campaign_id=rss_tech



At this point is looks as if Bit Torrent or some derivation there of will become the THE method for seamless video steaming\download, the battle is over who will control it, and your viewing access.

Control Geek.net wants to kill more White Mice

John Huntington of ControlGeek.net has posed the question: Just why does most live sound suck?
See his original post at  http://www.controlgeek.net/why-does-live-sound-suck/.



John has also posted a the start of a 'Concert Goer's Bill of Rights at http://www.controlgeek.net/blog/2008/3/26/concert-goers-bill-of-rights.html



So why does most live sound suck?



My thoughts on the situation:



1. Over the last 10 years there has been a progressive decline in audio quality contained in the mass market audio mediums, from CDs to the ubiquitous iPod.  While there are most certainly very high quality digital formats available for  the connoisseur,  the majority of music consumers are quite happy with a highly compressed MP3- especially if it is free!  So we start off with a general lower quality expectation by those who would actually go to a show. 



2. The cost of commercial real estate in nearly every major urban center can be extraordinarily prohibitive to investing in a quality acoustic design and upkeep.  Let's face it, most NYC venues are concerned with getting the most out of every event by keeping costs low and margins high-(moderate ticket prices, $8 dollar beers).  a Venue providing simply adequate sound is able to cut cost by installing 'shout boxes' which provide a very middle sound quality and tons of volume.  I have lost count on the number of  venues  I have attended shows where it was very obvious that pure volume was used to create excitement at the loss of depth-(the old Ritz anyone? ) I will say that I was blown away by the sound quality at the Lion's Den -(McDougall and Bleeker) some 15 years ago. I could hear every lyric and each of the 7 instruments being played.  Not only could I hear the music, I did not leave with my ears ringing for a week!  I went to see  a multitude of bands  at 'the den' I had never heard of -and in many cases never would again- just for the quality sound of the venue. (well, that and the beers were $2 if you showed up early).



3. We have to face it, there are a lot of live sound engineers who either



  • Never received any formal education in the art of live sound


  • Never served an internship with a veteran sound engineer and learned from their guiding hand.


  • Have blown their ears by doing it wrong but refuse to give up the back center stool.


4. It makes white mice spontaneously explode - poor white lab mice, everyone  knows high school sucks.



For the record I support John's Bill O' Rights for concert goers, but fear it will suffer the same fate as the travelers bill of rights - which appears to be suffering from lack of support and atrophy.



T6 readers: what are  your thoughts?  add them to the comment section of this post as this response is linked to John's blog.







Ah see, Dot vas the qvick fuse, Ya

After years of cajoling, pleading, and half hearted attempts to get the broadcast industry to educate the public on the 2009 transition, the FCC seems to finally a be putting some teeth behind it's mandate .  It appears that no one wanted to be the first to let us all in on the what and what nots and its affect on our television viewing. 



I heard  a report concerning the most recent escalation on NPR; the archived link its at -( with link to podcast of the original radio broadcast):



http://www.npr.org/templates/story/story.php?storyId=87898671&ft=1&f=1019



The TV broadcasters were concerned with causing a near panic ala Orson Wells War of the Worlds.



The manufactures of televisions had apparently been on a concerted program of deliberately misinforming  the public with phrases such as 'HD ready and 'HD Capable' in order to dispose of as many non native HD units as possible. I have consistently heard the terms used by the box store sales clerks to mean the same or different things, sometimes correctly.



The Cable companies up until late have been promoting the fact that they have (x) number of HD channels and that subscribers need not worry as cable had it all in hand. (what they don't tell you is that cable will continue to provide the standard analog signal for at least 3 years; this is good if you do not want to go out  and replace you 2 year old 37" monitor, bad if you wanted more HD content and upgraded you converter box to the DTV model only to have the majority of channels  stay at a lower SDTV quality.



So finally the FCC had enough with the industry surveys showing 3/4 of Americans having little or no knowledge of the transition-( or even the difference between DTV and HDTV)- and is clearly stating that a concerted attempt at public education must be made.   To this end the FCC has set up a countdown to DTV Transition site to help everyone get with the program.



The FCC  Digital convergence site -(complete with countdown clock!)  http://www.dtv.gov/



The FCC DTV FAQ : http://www.dtv.gov/consumercorner.html



WNBC TV in New York has had a great series of spots concerning the Digital transition and they archive them on their website!  Navigating the WNBC website is an arduous task -( it is an absolutely horrendously designed site). The direct Link is http://www.wnbc.com/digital/index.html



After the years of debating, arguing and endless conversation we are finally at a moment when there  no going back and all players are making efforts to get EVERYBODY on board.  After all this waiting I cannot shake the image of Liebkind in The Producers lighting the fuse only to find it is the quick one.

Personally, I blame Newton - If not for him, none of this would be a problem

I just finished reading  an article on www.Wirelessnetdesign.com about possible serious interference issues stemming from use of UWB by the proposed High Speed Bluetooth.  See the article:



Testing raises concerns over 802.11-based high-speed Bluetooth



http://www.wirelessnetdesignline.com/howto/206903929;jsessionid=YHRJOLR2A4BU2QSNDLPCKH0CJUNN2JVN?pgno=1



The article not only points out some interference concerns of UWB with standard Wifi\WiMax and  some IMT-2000 service, it is also a great primer on the technologies involved.



While I will not break down the article here -( you can read it for yourself,  it is not overly leaden with unfamiliar terminology and there are a ton of graphs)- the basic premise should be understood.  Radio frequency transmissions are an extremely poor way to transfer data as they suffer innumerable sources of signal degradation. The article focuses on the specific effects of UWB's technique of transmitting information in short low energy pulses but over a large bandwidth (typically  greater then 500 MHz), but the principals hold true for any RF installation.



We -(and especially consumers) have been influenced to view consumer RF (usually referring to the ISM bands) as a reliable well thought out standard in which every effort has been made to insure the units we use can resist interference or will not cause issue with other consumer systems.  Or as the article states

The reality is that consumers expect to be able to use multiple technologies simultaneously, without interference



Unfortunately two things make this concept a bit utopianstic.



  • FCC Part 15 - Go ahead read  it, very interesting stuff there -(no, really).


  • Getting a standard to market often involves trading pure concepts for workable solutions which allows for innovations and relative ease of implementation.


Regardless of the install type, the environment in which the system is put into can have a dramatic effect on the wireless reliability. Environmental factors can be external (Radio, TV, Aeronautic, STL, etc), Internal factors (wireless phone systems, multi-mode, frequency density and transceiver -(gateway)- proximity).  As the article states: 

...unless they are located approximately 8 meters apart for 2.6 GHz and 16m apart at 2.3GHz. If they are co-located in a single device achieving this level of isolation between radios is unrealistic...

For UWB the answer stated in the article is a method of  Time  And | OR   Phase intervals, which is fine for UWB but is not a current practical method for standard wifi.  Note the distances the article states for minimum separation! 8- 16 meters ! The basic concept of providing adequate distances between RF devices and their transceivers is just as important as antenna orientation and frequency allocation.



There are some great resources on the web which can help you get the basics



Air Magnet - www.airmagnet.com - have fantastic webinars on all aspects of wireless systems, if you cannot catch one of the live sessions they archive them all. In fact I just received a notice for a webinar on the 26th entitled:  802.11n Primer: What You Need to Know" --  It looks like a good one.



The fine folks at Infocomm international - www.infocomm.org  have a couple of great on-line classes concerning  network functionality of which the Audio-Video & control System Networking is full of great information.

Why Do All British Computer Geeks Look Like They Just Stepped Out of a Doctor Who Episode?

In my effort to catch up on tech news and obscura I came across a BBC article about an exhibit on the British Micro more often called the Beeb.



http://news.bbc.co.uk/1/hi/technology/7303288.stm



I am struck by a number of things in the article



1.  That nearly all 'home' computers circa 1980 looked like giant typewriters



2. Just how fantastic the BBC \ Acron effort succeeded in improving general literacy and raising a generation of computer literates. I can only dream of such an effort being undertaken in this country.



3. They sold 1.5 million of these babies!



4. Fast! with an 8bit\ 2MHz processor.



5. Did the British tech society have a special set way of being photographed? I swear every picture I see looks like it is a promotional shot of a Tom Baker episode of Dr. Who.   The man who practically single handedly forced modern computing into existence - Alan Turing-  looks almost Bogart like in comparison.  ( Mr, Turning is also one of the main reasons the Germans were defeated in WWII; I would argue equal  to the impact of the heroics of the D-Day soldiers)

Every Show Has A Victim, Don't be the Victim OR Your Only as Good as Your Last Cue

John Huntington of ControlGeek.net  has made me aware of a book by Steve Alcorn of Alcorn McBride concerning his experience building  Disney's Epcot center.  I have only had the chance to read the previews and reviews, I am told that Steve  convincingly describes the harrowing scramble to get everything working  just days prior to opening of Epcot. Any one who was worked on theatrical or event based installations know all to well the truth of this posts title. 



You can find  a helpful link to Steve's book via John Huntington's Blog page - (the link through gets John  a bit of revenue, go on help a brother out!).  www.controlgeek.net

Mass vs. Volume or Factors in Displacement

So the FCC has finally been able to presumptively sell off the soon to be unused analog television frequencies for over 19 billion dollars.  Unfortunately the spectrum went mostly to one company. When the FCC announced the sale of the frequencies it hailed the action as a dawn of a new age of innovative communications. The fact is, it took a classic chess move on the part of Google just to insure 'open access for other vendors.  (Google convinced the FCC to accept the concept of open access if a minimum bid was received. Google then bid the minimum, made quite noise about being interested in expanding to telecom then watched as the bidding frenzy ensued.



What does this mean for the custom AV industry? For starters if may mean that Sprint and its WiMax may have lost the mobile content war, for I am sure that Verizon has plans afoot to use the acquired frequency spectrum for more then just better coverage.  Content delivery is where the future profits reside.   Verizon has stated that they intend to honor the open access clause but past closed market practices lend me to believe that they will now work to overturn the clause and elbow out all others.  It could very well be a case of  Volume vs Mass. I have this image of  dropping ice cubes in a cup of water, when the ice fully melts the level in the cup does not change-(i am excluding factors such as evaporation and condensation).



NPR had the best general coverage on this FCC spectrum sale

"hello. Er, look, I'm sorry I'm a bit late. I've had the most ghastly time, all sorts of things cropping up at the last moment

Well, its been awhile - sorry for the delay I almost thought I would end up like  the Great Prophet Zarquon - late on arrival and cut off at the last min-



"Max blinked in amazement. He threw up his arms to the audience.



"A big hand please, ladies and gentlemen," he hollered, "for the Great Prophet Zarquon! He has come! Zarquon has come again!"



Thunderous applause broke out as Max strode across the stage and handed his microphone to the Prophet.



Zarquon coughed. He peered round at the assembled gathering. The stars in his eyes blinked uneasily. He handled the microphone with confusion.



"Er ..." he said, "hello. Er, look, I'm sorry I'm a bit late. I've had the most ghastly time, all sorts of things cropping up at the last moment."



He seemed nervous of the expectant awed hush. He cleared his throat.



"Er, how are we for time?" he said, "have I just got a min-"



And so the Universe ended." (Thanks to: http://www.otostopcu.org/yazi/h2g2/b2c19.php)



Truth be told I've just been damn busy my friend, that and a new house, my oldest entering the fabulous two's and my youngest, who has never been too fond of sleeping -(I am not kidding people ,this kid stayed awake for 15 hours straight a day until two months ago. He's 9 months old).  Soooo, my wife and I have been taking sleep where we can get it, which means the blog took a second to everything else.  Prior to my second child I had been very used to operating on 4 -5 house of sleep, even with our first, but it was getting ridiculous at only 3 hours a night without working. Thankfully my youngest has come to see the reasonableness of 8 straight at night, and the occasional 2 hour nap -(which as also allowed my wife to climb back into near sanity).



T6 in form and function followed the style of the music fanzines which I am an avid reader of -( such as www.TheBigTakeover.com and www.pitchfork.com ) and as an homage to Mark Shubin's Monday Morning Memo.  While I like the comprehensive magazine presentation, the process can be very time consuming and not always easy for every one to take in. With a new found energy I am back and will continue to post under the Tuesday moniker here but post my missives on more of a daily -(or semi erratic form there of) - schedule. 



I want to thank all those who have asked me about the blog when calling in for support at Crestron or by email, your interest and support have kept me from writing into T6 one final Obit for itself.



Please feel free to send me your links and observations in return for my undying appreciation and you name in Trebuchet MS 10 point font.

Killer Wi-Fi?



.



.



Around the world, fears persists regarding the possible health risks of Wi-Fi



.



Q: Scenario: I am running my laptop at Starbucks. What is my risk compared to other radio frequency activities?



A: The amount of energy that access points emit is very tiny. I did a survey of wireless LANs lasts year and in all cases the signal strength was tiny compared to other sources—such as cell base stations. Most client cards in a laptop emit power that is substantially less that what a cellular phone emits.





At the same time, the speed of the interface is usually very high, but it only transmits in pulses, depending on bottlenecks in the system and handshaking protocols. It is not a continuous transmission. So you are looking at an access point that has the power of a cell phone, and is only transmitting for 1/1000th of the time. So the exposure is trivial compared to that of other sources.

T6 Commentary:  The fear of electricity and Radio waves being the cause of a host of diseases has been around since the time such technologies began to become ubiquitous. In the Early 20’s magnetism and ‘Electro-Therapies’ replaced snake oil as the cause\cure of all manner of aliments –(some of which may still offer hope even today, though with much of the over-reaching claims tempered).   Today Cell phones and wireless transmission technologies have become the new bogeymen. In the 50’s it was the dangers of nuclear radiation, today it would the ‘microwave’ transmissions which would be the cause of all the mutation in the movie THEM! Of note is a full on medical study of the effects of EMF generated by high power lines on long Island and a relationship with a spike in breast cancer. The Study was to look for a link between the high power lines in the backyards of a particular community and the abnormal numbers of cases being diagnosed in the area. After several years and multiple studies NO link could be found. In the late 90’s a few studies indicated that excessive cell phone use could lead to brain tumors and some suggested a correlation to birth defects –(due to the proximity to the reproductive organs – especially men- and that many cell phones are worn on a belt).  The initial tests have yet to be reproduced in other clinical studies.  I can tell you that I can speak from experience that EMF from lower UHF transmissions has some effect on a person, given proximity and duration of exposure. When I first started working for a high end staging company I was a rental test technician and one of my responsibilities was to assemble and test medium to large  wireless microphone systems.  Most of the time this testing consisted of 4 or 5 units in combination, often the days testing would be broken up by testing and packing 4 track recorders or other AV pieces, as well as wireless mics. On such variety days I would not notice any effect of working around such equipment all whilst in direct view of the World Trade Center broadcast antenna. Then there were the days we tested large packages of wireless with 10-15 units per rack, and often multiples of this setup. I would often leave work with a heady ‘high’ which would only dissipate after an hour or so away from any testing. We assembled enough of these systems during my 2 years as a rental tech to notice the onset of said ‘high’ with large systems.  The high left you with a felling of levity, silliness and just a bit unbalanced. I can only relate the feeling to what I feel when I eat then attempt to be ‘athletic’, nearly sick but not debilitating so. Is there still to be a definitive clinical study, which will send a shock wave through the populace as much as the announcement in the 60’s from the Surgeon General on smoking did?  So far the evidence lends it self to the unlikely tag at least for the power levels of the devices in question.  My anecdotal evidence aside, I do not fear my daily exposure to the wireless world.

T6 Commentary:  WiMax is picking up steam as more and more companies join on see the possibilities for WiMax as a Muni-Fi system which can also provide content and possibly transition into THE information backbone for most urban areas.  With WiMax claiming to be the standard for 4G mobile devices –(somewhat undermined by the standards committees stating this is but a start)- the expectations and the heat is on for Sprint, et al to deliver and soon.  WiMax has made faster inroads to the muni-fi transition then comparable WiFi systems but it is still a bit like the dress rehearsals then the actual performance – who knows just which will play the leading role. And yet, with all this promise I am starting to get the feeling WiMax may just be the technical consortium equivalent of Naked Came the Stranger. The book ‘Naked came the Stranger was an experiment to see if a disjointed novel based only on sexual content could become a best seller. Written by a set of authors who did not know what the others were writing but only a loose outline of the plot, it nearly became a touchstone.  The Concept of a WiMax backbone replacing conventional broadcast and even new media upstarts is intoxicating, but given the fact that the entire concept was a knee jerk reaction to Sprint being given a deadline to use it or lose it for the frequency spectrum it had ownership to, one has to step back and wonder.

Best Buy Launches Educational HDTV Campaign



.



.



The retailer based its assessment on a privately commissioned survey showing that 41 percent of HDTV owners understand “little to nothing at all” about high definition, while 89 percent of all consumers don’t completely understand the technology or what it takes to experience it fully.



.

T6 Commentary:  The very fact that a large electronics Box store would need to implement such an education program is proof that the everyday person just does not care. Even with the analog cutoff dates fast approaching, large numbers of consumers know only the bare minimum if anything about HDTV. You and I, dear reader, may be caught up in the minutia of 1080i vs 1080p or the bandwidth concerns of 1440p but the mass market is fairly unimpressed. It is true that your rabid sports fan will be wowed by the 1080i image at a sports bar but give them a 480p ‘flat panel’ display at home and they are just as bowed. Yes, compared side-to-side your mass-market consumer will want to pick the 1080p display, show him the price and  ‘480p looks really good too’.  For a long time there has raged a debate between Gary Krakow –(tech writer for MSNBC.com) and his readership on content quality and content diversity. Mr. Krakow wrote on several occasions on the ‘poor’ quality of Satellite Radio audio –where XM promised “CD quality” audio but could not deliver this, and he wrote on how much this pained him.  The uproar this generated in emails to Mr. Krakow was impressive. The typical arguments consisted of defending the ‘sub-par’ audio and lauding the variety and availability of musical genres available, many stating they would even pay more to have greater variety at the cost of audio quality. In contrast, the average sports fan is drawn to Hdnet for the quality of image but it MUST have the quantity of sports or teams to satisfy the purchase.  Hdnet and Direct TV would be little if not for the sports packages.  The Custom home market clientele will always be just as concerned about image quality as well as variety, but for any technology to survive it must cater to the not so well off to become truly mass market.  HD is legislated to become the only game in town shortly, but if the desires of only the first adapters are taken into account the transition could hurt everybody’s bottom line. The afore mentioned premise is readily supported by the article on the Tvpredictions.com site where Swanni reports: HD Owners Yawning at HDTV DVD Players- http://www.tvpredictions.com/npd091907.htm.

Swanni's 2007 'Best & Worst' HDTV List



.



.



The High-Definition TV picture is so clear that aging signs and skin imperfections are dramatically visible. Phillip Swann, president of TVPredictions.com, has generated international media attention for his 2004 list, 2005 list and 2006 list of the 10 celebrities who look better -- and worse -- under the unforgiving lens of high-def. Now, Swanni has named his 2007 'Best and Worst' in HDTV



.

http://www.tvpredictions.com/swannihdlist091907.htm

T6 Commentary: Fast on the heels of HD Owners Yawning at HDTV DVD players article, Swanni publishes yet another list of the best and worst looking celebrities in HDTV. I am still concerned about the ‘logan’s run’ effect HD will have on the quality and tenor of movies and media. In reading the HD user group chat boards I see a great deal of complaining on how this or that news broadcast was only in 480i and how outrageous it is that the networks have not fully embraced the HD revolution. My question, do you really need to see the local news in HD?  If Walter Cronkite were just starting out today, do you think he would survive his HD test shots? Ten years from now will we forever be denied the opportunity to experience performances from the likes of Steve Buscemi?  Will we look back at the Pre-HD late 20th, earth 21st century movies as the last time the average person had a chance to make film?  Will our children only see films that star S1mOne actors?

HTSA Confirms Blu-ray Support

T6 Commentary:  Interesting but it may be- as the article also points out- be a bit too pre-emptive. With the two major players still jockeying for even the slightest statistical dominance in the tech press and now two alternative ‘HD’ formats starting to take a serious hold in India and China, world market dominance may be a foregone loss.  One only has to think of the sheer numbers in each country to realize what an impact acceptance of an alternative format means. Ignore the copyright issues for now –(a BD or HD disc could be easily hacked and converted) and see how the alternate formats would expand beyond the borders to its neighbors, including parts of ‘partner’ nations in bed with Sony or Toshiba.  The battle now is really for Europe and the Americas.

Sharp Ups Format-War Ante With Terabyte Blu-ray Recorder



.

Sharp introduced its newest Blu-ray disc recorder, which also has a hard drive that will hold one terabyte of data. The unit is only available in Japan, where it will sell for the equivalent of about $2,600. The product launch is the latest episode in the high-definition DVD format war that continues between Sony's Blu-ray Disc format and Toshiba's HD-DVD.

T6 Commentary:  A terabyte of video data on a recordable disc. Now that is interesting.  Perhaps this could record a feature length film in 1440p? (which will be available in 5 years or later), or just a boat load of Blu-Ray movies.

The Music Industry Begins to Eat its Young – link credits to Phil Pfisterer and Harry Negro





.



.



A car repair firm has been taken to court accused of infringing musical copyright because its employees listen to radios at work.





The PRS claimed that Kwik-Fit mechanics routinely use personal radios while working at service centres across the UK and that music, protected by copyright, could be heard by colleagues and customers.



It is maintained that amounts to the "playing" or "performance" of the music in public and renders the firm guilty of infringing copyright.

T6 Commentary:  The links to this story were forwarded to my by Phil and Harry who well know my past defense of artists rights and DRM in particular, given my background in recording studios and post production facilities. Both also know my continuing struggle with the draconian methods copyright organizations such as ASCP and RIAA have decided to implement. This action by the PRS is just, well, as stupid as ASCP going after a 75 year old grandmother whose granddaughter was caught using ole’ grams computer to download songs from a file sharing site. The ASCAP lawyers went so far as to threaten to take the grandmothers home from her to pay for the ‘royalty violations’. In the particular case presented in the article, the legal fight is over just what constitutes ‘public performance’ of the music.  I was all set to pontificate on the silliness of the associated” copyright organizations and to question just how a ‘personal’ radio playing constituted a ‘public performance’, when I read a comment on Slashdot which, I feel sums it up perfectly: imagine a second-hand-smoke victim receiving a countersuit by tobacco companies because they were able to inhale cigarette smoke they hadn't paid for. Nicely – see all the comments at http://yro.slashdot.org/yro/07/10/07/2335244.shtml\

T6 Commentary:  I am sure all of you are watching with a curious eye the rippling effects of the sub-prime mortgage debacle is having on the US home market.   How much of an impact this will have on the industry is to be seen but less new home building cannot add up to more installations. While new home will continue to be built and the sale of mega mansions appears to be growing not slowing , the middle high-end market will indeed shrink.  Add to this the report from Bloomberg news:  A July decline in demand for high-yield debt and the prospect of a slowing U.S. economy have led private-equity firms and their banks to forsake deals or renegotiate terms. http://www.bloomberg.com/apps/news?pid=newsarchive&sid=a19lYHqxzqLk, where even the uber moneyed dealmakers are having liquidity issues and one has to wonder what is in store for next year.  Undoubtedly alternative sources of revenue will have to be tapped and heavy promotion to those potential clientele who sit on the fence or are even off handedly considering home theaters or distribution systems with control.   The moneyed fence sitters will need a different tack, as they are not looking for the glam and zing of a device but its service and ability to solve an issue. I can speak to this from experience as I have a friend who works with a world class hedge fund –(he works with physicist who apply 12 dimensional universes math, chaos theory and tenets of the grand unified theory to help track and predict markets)- and is a bit moneyed –(home in the better parts of South Oranges and an apartment in Paris. The apartment would make my house seem small). My friend, being the curious lot that he is, asked me about the work I do and what it would take to install a distributed AV system in his NJ home. When I described to him several options, including touch screen based systems, and showed him some of the Award winning installs from CEDIA, he shut the door on the whole concept.  Why you may ask?  The concepts presented in the CEDIA sites were too flashy, too much of the technology as furniture for him.   Now this is the same person who plays with glee in his neighbors home theater system. Why the contrast? For many of the moneyed –(especially the well educated and old money crowd)- the draw of home automation exists but its impact on the overall atmosphere of a home is of great concern.  These are the folks who buy system that cover their 50” plasma TV’s with ‘art work’ as to keep them hidden when not in view. The point is that the same technology can be used but its presentation in an installation and –more importantly- at sales time- requires the subtleties rather then the overwrought high impact eye candy presented to the home theater enthusiast.  In this case I often consider how my mother –(who certainly does not come from the moneyed set)- treats having a TV in her home. For as long as I can remember she has taken great pains to ‘hide’ the television and the remotes behind an armoire and surrounded by books she has actually read, usually twice. Her reasoning? (And I am paraphrasing here) ‘I know, I watch more TV then I would like to admit but I don’t want my home to appear as a temple to it’.
