Description

In this paper, we propose a novel scheme for accomplishing rapid channel zapping on IPTV broadcasting services. Today, channel zapping delay is a crucial issue for digital TV broadcasting, which entails audio/video data buffering before reproduction. Such delay could be mitigated in an IP environment if a receiver accelerated this buffering using additional burst transmissions from dedicated servers when a channel zap occurs. However, most of conventional solutions are based on the unicast burst, which may cause an impulsive server/network load because channel zaps apt to happen simultaneously when programs are finished or suspended by commercial messages. To suppress this load, we newly propose a multicast-based solution considering the timing variation of channel zap on each receiver. Through verifications on a prototype system, we have confirmed a maximum 1-second reduction in the zapping delay using commercial multicast streams.
