Can broadcasters now transmit 1080p HD content to your home? How about Dish Network, DirecTV, and cable companies? If so, how would picture quality compare to that of Blu-ray?
On August 25, Dish Network announced it would begin transmitting high definition TV programming using the MPEG4 Advanced Video Codec (AVC) in 21 markets. By itself, that’s not much of a news story.
Dish Network HD TV Broadcast
What did make the headlines was the second part of the announcement. Dish now plans to deliver HD video-on-demand (VOD) programming in the 1920×1080 progressive scan HDTV format. The Dish press release promises (in their own words “…the availability of movies in Blu-Ray Disc quality 1080p resolution” but goes on to state later that their TurboHD program service offers “…the highest quality HD available, including 1080p where applicable.”(Doggone it, there’s always a catch!)
Aside from that, you’re probably wondering: Can Dish really deliver 1080p video to my home? If so, then why not Comcast, or Time Warner? Why not CBS and NBC?
The answers aren’t simple, but yes, Dish really can deliver 1080p. So can DirecTV, and every cable company currently transmitting HD. For that matter, so can any TV station currently transmitting over-the-air HD in the 1080i format.

If you are like many consumers who are in the market for a new television, you’ve probably dreamed about making it a plasma or LCD flat screen HDTV.
May be you spent some time looking over the Sunday circulars from Best Buy, Circuit City, and other major retailers. Perhaps you spent some time on the internet, shopping around for the bets price. You may even have read a few product reviews here and there.
It’s also probable that, like your fellow shoppers, you aren’t quite sure exactly what the difference is between LCD and plasma. Sure, they’re both flat. One seems to be brighter than the other, but a little washed out at times. Some are marked HDTV, you might know what that means, but what does “EDTV” mean?
Panasonic 150-inch plasma TV
Is your new flat-screen TV going to “burn-in”, “burn-out”, or “burn-up”? Just how long will it last before you have to replace it? Does the gas leak out of a plasma TV? Will sunlight hurt your LCD TV?
And just who are all of these companies selling LCD and plasma TVs? Sure, you’re heard of Sony and Samsung, Panasonic and Philips, Polaroid and Toshiba. But who the heck is Maxent? Funai? Ovideon? Syntax? Vizio?

Defective Pixels (Hot Pixels, Dead Pixels, Stuck Pixels)
LCD Display Pixels With 3 Sub-Pixels
Defective pixels plague almost every brand of LCD televisions manufacturer like top brand Sony, Samsung, Sharp and LG. The LCD monitors in your office desktop, or laptop LCD monitors might have defective pixels problem too. Each pixel consists of three sub-pixels, which are red, green and blue. Each sub-pixel can be controlled independently to yield different combination of color. All the pixels arrange side by side and control the color of each pixel individually, and a whole bunch of well arrange pixels in order yield an image on the LCD television screen panel. Defective pixels can be categorizing to three type, which are hot pixels, dead pixels and stuck pixels. A hot pixel is a pixel which always on, or called glowing pixel. Hot pixels are usually best seen against dark background. Dead pixel, it opposite of hot pixel, always off (or unlit). Dead pixels are usually best seen against a white background, it just looks like a black dot in the white. However, stuck pixel is one or two sub-pixels are always on or always off. This defective behavior make the pixels only limited to display limited colors and it hardly to be notice except you test through your LCD screen panel.

In recent news of new LCD televisions lineup launch by Sharp, they claimed they are number One LCD televisions brand in Japan. Is this true? I searched for more supportive information to counter check whether Sharp is as “sharp” as they claimed.
Hiroshi Take, one of the managers of Sharp Corp.’s latest and most advanced television factory, beams like a proud father. The gleaming white $1.4 billion Kameyama factory, 260 miles southwest of Tokyo, came online in year 2004 and is cranking out thousands of Sharp’s hot-selling large-screen flat-panel Aquos TVs per month.
Sharp got its flat-screen focus from Katsuhiko Machida, the company’s president, who for years fretted that his outfit was doomed to be a second-tier player. When he ran Sharp’s television business in the 1980s, Machida says, the firm had trouble competing because it didn’t manufacture the most important TV component, the cathode-ray tube. Forced to cobble together parts bought from competitors, Sharp was little more than an assembler, cranking out sets that were always a little too expensive and a little too poorly engineered to attract many customers. It was a dispiriting struggle, says Machida, but it taught him an ironclad belief that is now axiomatic throughout the company: “If you are in electronics and you are not strong in TVs, your business and your brand will suffer.”
