In this paper, we present an efficient method for supporting wireless video multicast services. The method is based on storing multiple differently encoded versions of the video stream at the server. The corresponding video streams are obtained by encoding the original uncompressed video file as a sequence of I-P(I) frames using different GOP pattern. Mechanisms for controlling the multicast service request are also presented and their effectiveness is assessed through simulations. Wireless multicast video services are supported with considerably reduced additional delay and acceptable visual quality at the wireless client –end.
