Abstract

Digital video coding for extended-quality television (EQTV) distribution over a broadband integrated services digital network (B-ISDN) at a payload rate of approximately 135 Mb/s is considered. The contribution signal will be either the CCIR Recommendation 601 signal or a minor modification of it to maximize horizontal resolution, and the scanning parameters will be the same as NTSC so that the same monitor can be used to display either EQTV or NTSC TV. A compatible vertical improvement can be added initially, or in the future, that will provide additional vertical resolution beyond the capability of the present NTSC TV or Recommendation 601. Several coding techniques for video distribution are presented to maximize horizontal resolution, given the above constraints. Two of these video coding techniques allow extra bandwidth by using sub-Nyquist sampling techniques together with comb filtering
