It is important to develop the multicasting technology for video on demand (VoD) services in Internet Protocol Television (IPTV) system with multiple channels. In this paper, we proposed an architecture combining multicast and unicast batching channels without scheduled multicasting streams. To provide an acceptable service rate and waiting latency, the 80% multicast channel rate under the experimental scenario is believed to be the optimized allocation between unicast and multicast VoD channels. Depending on the time zone of the arrival and the popularity of the requested videos, the batching scheme with five different time zones was designed to increase the efficient usage of the transmission bandwidth, especially for the request on popular videos, and to reduce the unnecessary waiting latency, especially at cold time zone.
