Abstract

We present a novel video streaming technique called catching for on-demand delivery of `hot' (i.e., frequently accessed) video objects to a large number of clients. This technique not only significantly reduces the server and network resource requirements but also is capable of providing near-instantaneous service to a large number of clients. By combining this technique for delivery of `hot' video objects with controlled multicast for delivery of `cold' video objects, we design an efficient video delivery scheme referred to as selective catching. Through empirical studies, we demonstrate the efficacy of the proposed video delivery schemes.
