Abstract
A simple but efficient video codec is built for low-bit-rate videophone applications. The goal of this project is to construct a video codec at a low cost and good performance. In order to reduce hardware complexity, a simple interframe predictive coding structure is selected. The input pictures are partitioned into 2-D blocks, and only the blocks with significant frame differences are coded and transmitted to the decoder. The Block-list-transform (BLT) coding algorithm, a generalized DPCM, is used to encode the frame differences between the previously reconstructed picture and the current picture. Preliminary results using this coding system at 64 kbits/sec show reasonable coding performance on typical videophone sequences.
