Title: Video-On-Demand System for The Unlimited VCR Services
Inventor: KIM BACK HYUN
IPC: H04N21/433
Filed: 2000-08-22
Abstract: PURPOSE: A client buffer system for a limitless VCR(Video Cassette Recorder) service is provided to provide a limitless VCR service by storing and using video streams of multicast groups depending on the access time of a VCR and by using a multicast routing technique. CONSTITUTION: A client buffer system comprises a multicasting transfer server, a multicast router, and a client. A video server and memory device store various moving pictures and transfer video streams to a network. When the video streams are transferred by the request of the client, a multicast group ID(Identification) is included to the header information. The multicast router manages the transfer of video streams from the server and exchanges information about the path through which other multicast video streams are transferred with another router. A routing table is written and managed by the multicast router. If the client requests a VCR service, a transfer path for receiving video streams is reset employing the routing table. The client system stores the video streams in a buffer and plays back a video by decoding the compressed streams. The VCR service is requested to the multicast router. If adjacent video streams are transferred, the video streams are received by an MBA(Multicast Buffering Algorithm) from the multicast router. Therefore, an interactive VOD(Video On Demand) system providing a limitless VCR service is realized.
