Definition of HDTV

HDTV is an abbreviation of the English term that defines television to obtain high definition digital images.

This television standard offers exceptional video quality regarding the television image as a whole and provides only the 16: 9 format.

HDTV technology is inclusive of four video formats characterized by an effective variable resolution and by different modes as regards image scanning.

HD READY or 720p is the format that has an effective resolution of 1280 × 720 pixels with progressive scan whose update involves all 720 lines and the relative pixels of the screen.

Plasma screens are considered HD READY even if they have a lower resolution of 1024 x 768 px. FULL HD is the 1080p format with a total resolution of 1920 x 1080 progressive scan. The quality of the HDTV is defined by better image stability at higher resolutions which are greatly influenced by the contents of the transmitted signal.

The definition of HDTV programs is about four times greater than that obtainable with the DVD format but, despite the excellent compression capacity of the MPEG-4 algorithm, the space required for storing the files is very large.

To take full advantage of the characteristics of HDTV technology, it is necessary to be equipped with an entire HDTV system, therefore including a television and decoder capable of receiving high-definition television programs and an optical high-definition media player available in the form of Blu-ray and HD DVD.

By viewing HDTV content on a traditional TV, on the other hand, you wouldn't notice any difference for the better.
