Video over mobile telephone has a wide range of current and future potential applications. The integration of two new technologies, namely GPRS and MPEG4, makes it possible to transmit MPEG4 bit streams over GPRS Network. This paper presents the implementation details of MPEG4 coded video transmission over GPRS network. Mobile telephone is responsible for video data subsampling and is used as a player device. A testing result obtained after actual video transmission is presented in this paper. Based on the principium of RTP and the features of MPEG4 standard, we put forward a RTP payload format and a packetization algorithm for MPEG4 video, which achieves both efficiency and robustness. We present an end-to-end feedback congestion control scheme based on RTP/RTCP.
