Abstract :
Based on the client-server application model, an MPEG-4 speech/audio streaming system over the Internet is implemented and demonstrated. This system provides an architectural prototype for carriage of MPEG-4 data over the IP (Internet protocol) network via the RTSP (real time streaming protocol) and the RTP (real time protocol). MPEG-4 natural audio parametric coding functionalities are fully explored for the coding of speech signals at 2 kbps to 4 kbps and the coding of non-speech signals at bit rates of 4 kbps up to 16 kbps. A set of MPEG-4 oriented RTSP feedback controls is utilized for client-to-server interactivity.
