Multimedia Broadcasting over the Internet: Part II-Video Compression

In the first part of our project report, published in the October-December 1998 issue, we described a new technique for multimedia broadcasting over the Internet, called IP Simulcast. In this article we introduce a new video compression technique, called XYZ compression, which suits ultra-low bandwidth applications very well. Current technology permits delivering video over the Internet. Video applications on the Internet divide into the following groups: videophone and videoconferencing applications, viewing video on the Web, and video broadcasting. Delivering video via the Internet requires a combination of some compromises and clever engineering, summarized as
