Ziv, a research professor at the Faculty of Electrical Engineering
at the Technion, is the first Israeli to win the Medal of Honor - the most
prestigious award given by the union and one of the most prestigious in the
world of technology.
In 1977, research professor Ziv and Prof. Avraham Lempel of the Faculty of Computer Science published the initial version of the algorithm for waterfall Ziv, and in 1978 the second version. Both versions served as the basis for essential compression technologies including TIFF, PNG, ZIP and GIF and played a major role in PDF (for documents) and MP3 (for music) formats. This is an information compression algorithm that enables lossless compression, regardless of the structure of the data and without prior knowledge of the statistical properties of the data. On the basis of this algorithm, many of the compression technologies currently used in memory devices, computers and smartphones have been developed.
