  • Patent number: 4688106
    Abstract: A video processing system which allows sequences of video pictures to be transferred to disc stores in real time. These sequences can be read out of the disc store and processed before being returned to the disc store to be read out in real time. This effect is achieved by employing disc stores with five parallel heads so that five bits of information can be written in or read from respective tracks on the disc in parallel.
