HCP6: a high-quality conferencing platform based on IPv6 multicast

We introduce a high-quality videoconferencing application implemented using IPv6 multicast. The conferencing application is made to operate at IPv6 network environment on Microsoft Windows XP or 2000 enabled IPv6 stack. We implement this application using MPEG-4, MJPEG and Video-1 codec to support high-quality conference and can select one by necessity of usability. In this paper, we describe the software architecture that is divided three managements area, efficient buffer managements that is data transmission technique from Directshow filter to network manager, RTP and RTCP library, and DirectShow technology that is provided by Microsoft DirectX. And we present the experimental result that measures delay of a respective module and bandwidth of this application.
