A Proposal of Multicast for Personalized Media Stream Delivery

Abstract

This paper describes a scheme of network distribution that enables innovative broadcast content delivery service over the next-generation broadband Internet. The scheme enables producing diverse video/audio contents customized according to the user’s specifications and delivering such contents via streaming with guaranteed quality. The broadcasting of diverse media contents results in a massive consumption of network resources. We developed two multicast techniques, based on asynchronous and layered multicasting. One is an algorithm for statistical traffic control based on asynchronous multicasting that enables flexible bandwidth control to meet the network bandwidth design requirement for QOS. The other is a technique for the delivery of diverse media segments/objects based on a layered multicast technique, improved for the delivery of media with different levels of quality. We prove the implementability of the two techniques by designing network models and protocols using the latest Internet technologies and show their effectiveness by using numerical analysis.
