Part of the MPEG-2/DVB standard where half of the normal 720-pixel horizontal resolution is transmitted while maintaining normal vertical resolution of 480 pixels. Since it is a 4:2:0 format, the colour information is encoded at 240 pixels vertically and 176 pixels horizontally. Virtually all the DBS providers use HHR format since it dramatically reduces the bandwidth needed for channels, though at the expense of picture quality. Special logic in the video decoder chip in the set top box re-expands the picture to normal horizontal size by interpolation before display. 4:2:2 video at Standard Definition looks as good as the NBC analogue feeds on GE-1 Ku. High bandwidth 4:2:0 video such as the NBC digital feeds on GE-1 Ku come very close to studio quality and the low bandwidth video encoded in HHR format looks like DBS.
