What is an LED TV? Latest HD News Written by Admin    Friday, 16 October 2009 18:23 PlasmaInstaller.com would like to announce the acquisition of LEDTVINSTALLATION.COM! (NYTimes.Com-2009) When a product has become commoditized and its price is regularly dropping and its profit margins are getting ever-thinner, how can a company boost its sales and raise its prices? One way is by changing the product’s name. That’s what Samsung has done with its new line of LCD TVs using LEDs to illuminate the screen. In its print advertising and on its Web site, Samsung calls the new range simply “LED TVs.” They are not LED TVs. Calling them such makes as much sense as calling its existing line of LCD televisions Cold Cathode Fluorescent Lamp TVs, or CCFL TVs, after the lighting technology that they use. Whatever its validity, Samsung’s decision to drop “LCD” was a smart marketing move. After all, “LED” is the acronym du jour, a technology that’s all the rage as a new, perhaps revolutionary lighting source. It’s as emotive a term as “HDTV” and “digital” were in their heydays. But it’s also confusing consumers. An industry colleague told me that in a recent trip to a big-box retailer, he overheard several friends asking what type of TV they were watching. One said it wasn’t LCD or plasma, it was an LED set. Last Updated ( Friday, 16 October 2009 19:24 ) Read more...

TV About To Go Digital Latest HD News Written by Administrator    Tuesday, 18 March 2008 19:35 (CNN) -- An era in American broadcasting history will come to an end before the decade is out. Early in 2009 all over-the-air TV stations must switch the way they transmit their programming, bringing a number of changes not only to broadcasters and viewers, but to emergency responders and digital innovators as well. Since the advent of television, stations have sent their programming via analog signals. As a result of legislation passed by Congress in 2005, they will have to convert their transmission to digital signals by February 17, 2009. Broadcast signals travel over the electromagnetic spectrum, which carries all sorts of transmissions, including AM and FM radio, shortwave radio, radar and television, explained Duke University professor Stuart Benjamin. Analog TV signals occupy a big chunk of the spectrum. Last Updated ( Tuesday, 19 May 2009 06:45 ) Read more...
