Abstract: Most of proposed VOD systems are typically de- signed for one-to-one connection between a user and video server. However, it is inefficient and expensive way when server support multiple users who access the same video stream with a dedicated video channel. In this paper, we propose a scheme that can support an interactive VCR for all users requesting the same video stream with batching. To reduce a server I/O and network bandwidth requirement, dynamic buffer is allocated to access node which has variable play- out point. It makes possible interactive VCR operation as if customer uses true VOD system. Consequently, this scheme can just deliver a multicast stream without delay after an initial request or VCR action occurred. This policy can guarantee acceptable services to a number of users at minimum cost.
