QuIVeR: A Class of Interactive Video Retrieval Protocols
نویسندگان
چکیده
Video-on-demand (VOD) servers need to be eeciently designed in order to support a large number of users viewing the same or diierent videos at diierent rates. In this paper, we propose the Quasi-static Interactive Video Retrieval (QuIVeR) Protocol for this purpose when disk-array based video servers are used. Five variations-QuIVeR-1, QuIVeR-2, QuIVeR-3, QuIVeR-4 and QuIVeR-5-are presented. The properties as well as the relative merits and de-merits of each protocol are discussed. The protocols require no buuer at the server and hence, all retrieved segments are immediately transmitted to the appropriate users. The amount of buuer required at each user's set-top box is reduced to two video segments. Guarantees are provided for the avoidance of video starvation as well as buuer overrow at each user's set-top box. Numerical results, obtained using data from an MPEG coded \Star Wars" video, are provided.
