Abstract :
The Moving Picture Experts Group (MPEG) of ISO is considering a standard for storage applications below 1.5 Mb/s. A video coding algorithm developed at Bellcore that has been proposed as a contribution to the standardization activity of ISO/MPEG is described. The following characteristics of the algorithm are described. The following characteristics of the algorithm are described in detail: frequent periodic reset of the temporal predictor (to provide random access), interpolative coding of every second frame, flexibility of providing adaptive Huffman code tables for digital-storage-media (DSM)-based applications (not feasible for real-time transmissions), 1/2-pel accuracy in motion estimation, and optional quantization matrix. Additional features of reverse playback, fast searches, and random access are described.<>
