High-definition TV

HDTV offers up to five times the picture resolution of standard definition (SD) television. Picture resolution is a measure of picture quality and refers to the number of lines and number of pixels per line in the TV picture.

Ordinary SD pictures are broadcast at 720 x 576 pixels, whereas HD pictures can be up to 1920 x 1080 pixels. This means superior picture quality and detail, and more life-like and vivid colours.
