A key technical barrier to the growth of the information industry is the limited capacity of existing networks, many of which cannot carry large amounts of digital video. New technology is needed to increase network capacity while also reducing video transport costs. Universal access and low cost would be promoted if video could be delivered to personal computers (PCs), which are used by more than 100 million people worldwide and in many cases already are connected to networks. Cubic Defense Systems Inc. proposes to develop prototype video compression technology that will compress color image and synchronized audio data to greater than 150:1. The protocol design work is expected to be conducted by the Information Sciences Institute (ISI) at the University of Southern California. The compressed video data will be distributed over telephone circuits, packet-switched, and/or wireless networks. To enable high-quality, full-motion video to be recreated upon delivery, decompression software will be downloaded to the PC during the set-up procedure for the transmission. This approach should significantly reduce the cost of video distribution and will create new opportunities for interactive on-line services to include video. The technologies developed will be pilot tested on PC platforms and existing networks. If successful, the project will lead to new products and businesses; benefit industries such as semiconductors, computers, communications, software, and video production; and enable the United States to increase its share of the rapidly expanding video products and services markets.
