Advances in interactive digital multimedia systems

This paper introduces basic concepts in digital multimedia systems and surveys recent literature. Background is provided regarding developments in interactive videodiscs, which first made images and video accessible through computer systems. Digital storage media, including optical, magnetic, and network options, are addressed. The characteristics of audio and video and their digital representations are discussed. Because these media are so demanding of space and channel bandwidth, compression methods are reviewed. Standards for digital multimedia are considered. Current multimedia systems are described, and future prospects are indicated.<
