Getting started with High Definition Television
High Definition Television - a new type of television that combines a High Definition Television tuner and an HD-capable display. Almost all of HDTV available in the market use the 16:9 widescreen aspect ratio. A High Definition Television tuner can receive analog and digital broadcasts over the air. High Definition Television compatible TV features only the high resolution display and can only receive digital broadcasts if connected with a separate HDTV tuner. HDTV ready TVs can have the 16:9 widescreen ratio or the square like 4:3 aspect ratio. High Definition Television has arrived and here to stay given surging popularity of crystal-clear broadcasts in US television TV. Analog television's shift to an all digital system has heralded a new age in the 65-year history of TV. Hours of High-Definition Television can be viewed almost nightly. Viewers can easily determine if a show is presented in High Definition Television if the message "Presented in high definition where available" is shown at the start of a program.

The output at Kameyama, along with allowing Sharp to make more televisions, is also allowing the company to come out with a wide variety of them. The company now has four separate lines of LCD televisions, ranging in technical sophistication. Some of the televisions coming out this year will feature a refresh rate of 120 hertz; double the current 60-herz standard. In the second quarter, Sharp is expected to come out with a line of LCD televisions for gamers that will cut down any latency between the game console and action on the television.The system will be capable of sending two separate high-definition video streams between PCs and televisions through a home's electrical system. With Blu-ray and HD-DVD delivering true high definition content, Philips has come to the party with a true high definition LCD television in the Cineos 37PF9731/69. As a 1080p panel, it can screen high definition television, Blu-ray and HD-DVD in all their glory rather than down scaling them to fit on a 720p display. The television sports two HDMI inputs for connecting to HD sources, plus component, composite, s-video, SCART and VGA. Disappointingly it doesn't have an onboard digital television tuner.
Ambilight shines coloured light on to the wall behind the television to match whatever is on the screen, creating a halo of colour around the television that changes with the image. You can't see the actual Ambilight tubes when you're sitting in front of the television; they're hidden behind the bezel and pointing back at the wall. This isn't a problem if the television is wall-mounted in a location where you'll never have to see the lights, such as at the end of a long, narrow room. But if the television is against one of the long side walls, with the Ambilights visible off to the sides, it will give everyone else in the room the irrits very quickly even if it's just in their peripheral vision
