HD pictures have image resolution which is superior to SD pictures and to the existing analog, with up to three times the improvement in detail.
There are two different levels of high definition:

• 1920 pixels x 1080 lines @ 50Hz interlaced
• 720 pixels x 576 lines @ 50Hz progressive

The benefits of HD pictures at the highest resolution are particularly noticeable on larger screen sets and when using projection equipment. 

HD pictures are also ghost free and in widescreen format. When viewed on an HDTV screen the viewer can enjoy cinema-quality viewing with Dolby Digital sound (some HD programs).
