  • Decoding apparatus of a compressed digital video signal
    Patent number: 5291283
    Abstract: Encoded picture data or encoded difference data is decoded by an intraframe decoder. To an adder, zero data is given through a switching circuit at the time of the decoding of intraframe coded data, and when interframe coded data, i.e., difference data is decoded, a decoded value of a previous frame is supplied through the switching circuit. By the adder, the decoded value of the previous frame and the decoded difference value are added to allow the decoding of interframe coding.
