Abstract :
The provision of video communication over wireless links is a challenging task because there is difficulty to get better video quality guarantee for video transmission over the current wireless networks include GPRS or CDMA. In this paper, we developed a embedded adaptive live video streaming transmission system on GPRS/CDMA network based on MPEG4 video compression standard. This system presents a performance enhancement for real-time video transmission by employing an adaptive sender rate control scheme, which estimates the available channel bandwidth between the sender and receiver, then adjusts the output rate of encoder side using R-D framework and frame-skip control mechanism according to the estimated time-varying channel bandwidth.
