A video format with 1125 lines of resolution, a picture aspect ratio of 16:9, and 5.1 independent channels of CD-quality stereo surround sound (AC-3) introduced in the US in November 1998. HDTV formats include: (720p) - 640 x 480 pixels progressive · (1080i) - 1920 x 1080 pixels interlaced · (1080p) - 1920 x 1080 pixels progressive.
In fact, HDTV is just ONE of (18) formats that comprise the ATSC Digital TV Standard. But beyond all argument, HDTV offers the ultimate in TV Picture Quality. Yet to avoid any misconceptions, it’s important to note that Digital-HDTV is immeasurably, more than merely a “better TV picture.” HDTV standard pictures will have 6 times the resolution of current TV and it will be a full 60 frames per second temporal resolution which is twice the current NTSC images. Motion will be seen smooth and the picture will be clear enough to sit very close to a very large screen. The picture will be displayed in a panoramic 16:9 horizontal-to-vertical aspect ratio to be more like movies and add the feeling of realism to TV.

At present American TV has 525 lines per image and European TV 625, while high definition systems may have more than 1000.Many observers feel that the battle for high definition TV markets will be the next great world economic battle. ” [Answers.com] “…HDTV (high definition television) is a television display technology that provides picture quality similar to 35 mm. movies with sound quality similar to that of today's compact disc. Some television stations have begun transmitting HDTV broadcasts to users on a limited number of channels. HDTV generally uses digital rather than analog signal transmission.

It required a 20 Mhz channel, which is why analog HDTV broadcasting is not feasible in most countries. ” [Techtarget] “…A system for transmitting a TV signal with far greater resolution than the standard National Television Committee (NTSC) standards.

It is a digital format that provides an extremely high-resolution picture, accompanied by amazing digitally enhanced sound, all presented in glorious widescreen. What can be confusing is that HDTV is used to refer to several things: a type of TV, a digital broadcast method, and a special way to produce TV shows and movies. ” [ Philips Electronics ] “…Short for High-Definition Television, a new type of television that provides much better resolution than current televisions based on the NTSC standard. There are a number of competing HDTV standards, which is one reason that the new technology has not been widely implemented. All of the standards support a wider screen than NTSC and roughly twice the resolution. To pump this additional data through the narrow TV channels, images are digitized and then compressed before they are transmitted and then decompressed when they reach the TV. ” [webopedia]
