A Tutorial on Picture and Sound Compression, and an Introduction to JPEG and MPEG: Or, a Little Data can Go a Long Way!

This note comprises two parts: a tutorial on the storage and transmission of digital images and sounds in compact forms, and an outline of the JPEG and MPEG-1 standards for image compression. — Image and sound data is generally quite voluminous and taxes the data capacity of computers. Fortunately image and sound data is usually highly redundant, so digital compression techniques may be used to make more tractable the problem of storing and transporting images and sounds using computer techniques. — JPEG is an acronym for Joint Photographic Experts Group, an international standards group within ISO and CCITT that is standardizing a compression algorithm for continuous-tone still color pictures. — MPEG is an acronym for Moving Pictures Experts Group, a standards group within ISO that is standardizing the coding of moving pictures and associated audio information.
