Paper Abstract

In order to compress digital NTSC video sequences for transmission or storage, we have developed a Subband-VQ coding scheme where 2D frequency subbands of each picture frame are encoded using VQ coding techniques. In the Subband-VQ coding scheme, we take a multistage VQ approach to obtain good picture quality at about 6 Mb/s while avoiding a potential hardware complexity problem of VQ. In conjunction with the SBC and VQ coding techniques, motion estimation and motion compensation algorithms are implemented to fully exploit the temporal correlation existing in video sequences. The SBC-VQ scheme has a very simple decoder structure which mainly consists of table look-up operations.
