The implementation of a codec for real time applications such as video-conferencing at low bit rates is discussed. The discrete cosine transform has been used for compression, both in two spatial axes as well as in the time axis of the video sequence. A new method of frame by frame processing is proposed which reduces the real time delay associated with processing and transmission of successive video frames, with minimal memory and processing overhead. This implementation is inherently simple and also provides improved performance compared to other popular codecs
