HDTV stands for high-definition television. HDTV is about to heat up, it has the potential for very rich color, rich sound, and high-fidelity imagery.

HDTV Statement:

The elements of a simple television system are:

• An image source - this may be a camera for live pick-up of images or a flying spot scanner for transmission of films
• A sound source.
• A transmitter , which modulates one or more television signals with both picture and sound information for transmission.
• A receiver (television) which recovers the picture and sound signals from the television broadcast.
• A display device, which turns the electrical signals into visible light and audible sound.

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.
