A Video Transmission Framework Using Components and Multi-Agent Systems

This paper presents an application of video transmission over Internet, which goal is to be used in a cooperative platform. This application uses proxies during the transmission to adapt the video (changing the size, the frame rate and/or the encoding format). Adaptation is a necessity in this kind of application, due to the diversity of receivers (computers, mobile phones, PDA...). During the design process, we chose to use component oriented programming and multi-agent systems. We present here how these two paradigms help us to have a flexible and evaluative application, and, for each transmission´s step, what is the most appropriated solution. At the end, we also present tests that have been made to evaluate the power needed by the proxies in order to discuss about benefits that can be brought by our architecture
