Abstract	The development of multimedia systems, which can handle voice and video, is fast growing. Image and video capacity are the essential components of a multimedia system. Representing digital video requires large amount of data, thus, video compression is necessary. In this paper, the Hybrid MC/DCT video codec standard is examined and a video compression algorithm based on the present standard is implemented. The application of Hybrid codec is done with efficiency in mind to provide the least compromise between the computational speed and compression ratio. To make such implementation practicable, the heart of its compression algorithm; the discrete cosine transform, quantization and variable length coding are analyzed carefully. The techniques such as motion compensated prediction which do not considerably reduce image quality, however improve coding efficiency are incorporated in the code. Initially, we briefly review the compression standards; then the hybrid codec technique for the moving pictures is investigated.
