Abstract :
Today, VoD is an important technology for many applications, and a number of periodic broadcasting schemes have been proposed to support a large number of receivers. However, these schemes are not suitable to the environment where wired and wireless devices coexist. With the existing schemes dealing with heterogeneous receivers, the service latency of low-end clients is reduced by sacrificing that of high-end clients. In this paper we propose a novel scheme reducing the service latency of high-end clients as well by partitioning the first segment and transmitting them through sub-channels added according to the network condition. Computer simulation shows that the service latency is significantly decreased compared to the existing scheme.
