  • Method for encoding and transmitting video signals as overall motion vectors and local motion vectors
    Patent number: 5006929
    Abstract: A redundancy reduction algorithm, such as hybrid DCT, is applied to a video signal and is subsequently encoded by pixel blocks, and motion vectors are generated for each image block. At least one global motion vector is then generated for the entire image, the block motion vectors are substracted from the global vector to obtain local motion vectors representing the shifts from the global vector, the global vector is encoded with fixed length, the local vectors are encoded with variable length, and the coded global vector and the coded local vectors are multiplexed into the coded video signal to be transmitted.
