Abstract

In a video decompression system for decompressing compressed image data wherein odd and even fields of video signal are independently compressed in sequences of intraframe and interframe compression modes and interleaved for transmission, the odd and even fields are independently decompressed. During intervals when valid decompressed (45, 46) odd/even field data is not available, even/odd field data is substituted (47-51) for the unavailable odd/even field data. Independently decompressing the even and odd fields of data and substituting the opposite field of data for unavailable data may be used to advantage to re-duce image display latency during system start-up and channel changes.
