HDTV stands for high-definition television. HDTV is made up of two formats, called 720p and 1080i, it has at least 900,000 pixels.
HDTV Truth:
Another reason for HD-MAC's failure is that it was not realistic to use 36 MHz for a high-definition signal in terrestrial broadcasting (SDTV uses 6-, 7- (VHF), or 8-MHz (UHF)).
HD-MAC could be used only by cable and satellite providers, where there is a wider bandwidth available. Thus, analog HDTV could not replace conventional SDTV (terrestrial) PAL/SECAM, making HD-MAC sets unattractive to potential consumers.
Display technology
Thanks to advances in display technology, there are now several kinds of video displays used in modern TV sets:
- CRT : The most common displays are the ubiquitous direct view CRTs for up to 40in (100cm) (in 4:3) and 46in (115cm) (in 16:9) diagonally . These are still the least expensive, and are a refined technology that can still provide the best overall picture quality. As they do not have a fixed native resolution , in some cases they are also capable of displaying sources with a variety of different resolutions at the best possible image quality.
- Rear projection : Most big screen TVs (up to over 100 inch (254 cm)) use projection technology. Three types of projection systems are used in projection TVs: CRT-based, LCD -based, and DLP (reflective micromirror chip) -based. Projection television has been commercially available since the 1970s, but could not match the image sharpness of the CRT; current models are vastly improved, and offer a cost-effective large-screen display. A variation is a TV projector , using the same technology, which can project onto a wall.
- Flat panel LCD or plasma : Modern advances have brought flat panels to TV that use active matrix LCD or plasma display technology. Flat panel LCDs and plasma displays are as little as 4in (10cm) thick and can be hung on a wall like a picture or put over a pedestal . Some models can also be used as computer monitors .
