Message-ID: <1991Jun10.185834.3927@waikato.ac.nz> Date: 10 Jun 91 06:58:34 GMT Article-I.D.: waikato.1991Jun10.185834.3927 References: <22285@imag.imag.fr> Organization: University of Waikato, Hamilton, New Zealand Lines: 19 In article <22285@imag.imag.fr>, gourdol@imag.imag.fr (Gourdol Arnaud) questions the need for MPEG, saying the proprietary algorithms are already very good. The April issue of the Communications of the ACM was a multimedia special. I'd recommend it for anybody wanting very good, yet not highly technical overviews of what JPEG and MPEG are all about, as well as other interesting subjects like designing video formats for interactive access, and getting video to work over a 64K-bit channel. One of the articles even had a performance comparison in it. As I recall, there was no significant difference between MPEG and Intel's DVI (if that's the proprietary algorithm you were thinking of).
