1. A video-data storing device comprising:

  • data dividing means for receiving interframe coded video-data and providing a frame of interframe coded video-data;

    information source decoding means for restoring video-information by decoding the frame of interframe coded video-data;

    intraframe coding means for encoding the restored frame of video-information in an intraframe coding mode;

    video-data transferring means for transferring one of the frame of interframe coded video-data and the encoded restored frame of video-information for data storage;

    control-signal deciding means for determining whether or not the frame of interframe coded video-data conforms to a predetermined standard and for issuing a control signal indicative of such a determination; and

    frame-processing control means for receiving the control signal from the control-signal deciding means, wherein the video-data transferring means is controlled, in response to said frame-processing control means receiving the control signal indicating that the frame of interframe coded video-data fails to conform to the predetermined standard, to store the encoded restored frame of video information outputted from the intraframe coding means in place of the frame of interframe coded video-data.
