Abstract

An Internet Protocol (IP) based high-quality real-time audio-visual (AV) communication tool has been developed. A digital video (DV) camcorder and VCR, being consumer market products, are adopted as the AV codec. The AV devices, which have an IEEE-1394 (Firewire) interface, are connected to the IP host with its interface. The original packet format is adopted by simply encapsulating the isochronous stream packet of the DV with UDP/IP. In the highest quality of communication, the system consumes over 35 Mbps of network bandwidth. The system can also change the bandwidth adaptively for end-to-end network conditions. The DV communication effort was performed using the APAN TransPAC link between the USA and Asia (Japan and Korea)
