A multicast communication system over Internet and its application

Abstract

Many networking applications become feasible and required with the popular use of Internet. We present an Interactive Digital Radio Station, which is called IDRS, over Internet. Several architecture and synchronization methods are proposed to solve the communication problems that only occur during the digital radio multicasting. In order to perform the communication between DJ and audience, two operation modes, which are called the DJ mode and the Call-in mode, are defined. Related technique issues and the corresponding system development are presented in detail.
