Design and application of buffer simulation of real-time streaming media

The decision of receiver buffer length is very important for real time streaming media. Different buffer length get different quality of playback even under the same network circumstances such as algorithm of transmission and playback. Due to the importance of receiver buffer for the streaming media, in this paper we study the principle of buffer and design on a buffer simulation platform of real-time streaming media. This platform realizes complete buffer simulation of real-time streaming media, including sending, transmitting, receiving and playback of the video data. To test the platform, an improved algorithm for real-time video dynamic playback based on PI controller is simulated on this platform. The experiment result shows that this simulation platform is valid.
