Research On Embedded Streaming Media Real-Time Transmission Synchronization Control Strategy
Guo Hai-tao, Tan Huai-Liang · 2013
For the real-time transmission of stream media, a novel synchronization control strategy is proposed in this paper. The strategy includes the layer-based flow control algorithm and the delay jitter compensating algorithm. In order to avoid the network congestion and ensure that the data transmission is not less than the frame bit-rate, the former adjusts the streaming media frame bit-rate and the transmission rate on the basis of the detected network transmission performance. According to the feedback information on the occupancy of the receiving buffer, the latter adjusts the transmission strategy to ensure the quality of streaming media services and compensate the negative impact of delay jitter. The experimental results indicate that this strategy achieves the synchronization of streaming media real-time transmission.
