Abstract :
The CCITT V.42bis standard for data-compressing modems, a conservative and economically implementable scheme, is discussed from algorithmic, experimental, practical, and marketing standpoints. It is shown that 4.2bis compresses text about as well as the Lempel-Ziv-Welch algorithm of the Berkeley Unix Compress utility. Other Ziv-Lempel variants are discussed briefly.<>
