This article surveys the techniques and standards for compression of full-motion video. Two standards and related techniques are described and evaluated: p x 64 (or H.261) standards for video-based communications and MPEG standard for intensive applications of full-motion video, such as interactive multimedia. Both techniques use the combination of DCT-based intraframe compression and predictive interframe...
This paper is the first part of a comprehensive survey of compression techniques and standards for multimedia applications. It covers the JPEG compression algorithm which is primarily used for full-color still image applications. The paper describes all the components of the JPEG algorithm including discrete cosine transform, quantization, and entropy encoding. It also describes both encoder and decoder...
