An architecture of muldimedia platform for integrated audio-visual data processing

In this paper, we introduce an experimental hardware architecture of a multimedia data processing system called ComBiStation, whose application area includes multimedia authoring, CSCW and video conferencing. The platform comprises most commonly needed multimedia processing functions : audio-visual data capture, playback, multistandard compression as well as interleaving of compressed audio visual data. The proposed architecture minimizes the CPU overhead that might be caused by multimedia data processing and assures the fluent data flow among system components. We begin with overall architecture of the whole system, and then audio-visual data capture/display unit and multistandard compression unit are discussed. Implementation issues and future works are also discussed
