  • Video signal compression apparatus for independently compressing odd and even fields
    Patent number: 5185819
    Abstract: In a video compression system odd and even fields of video signal are independently compressed in sequences of intraframe and interframe compression modes. The odd and even fields of independently compressed data are interleaved for transmission. The fields are interleaved such that intraframe even field compressed data occurs midway between successive fields of intraframe odd field compressed data. The interleaved sequence provides receivers with twice the number of entry points into the signal for decoding without increasing the amount of data transmitted.
