Abstract

The problem of transmitting widescreen HDTV signals to the home in a bandwidth-efficient manner has elicited many novel proposals, each having its own set of trade-offs. Most proposals assume some degree of compatibility with the present NTSC transmission standard. A small number of these proposals, such as the Advanced Compatible Television system,1,2 claim "full single-channel" compatibility by requiring the encoded signal to "look like" a normal picture on a conventional NTSC receiver and to occupy no more bandwidth than a standard 6 MHz RF channel. This paper discusses how cooperative paired processing can be used in video systems to simultaneously embed auxiliary video information within a main signal and to insure crosstalk-free recovery at the decoder.
