| Abstract: | Receive buffer plays a key role on ensuring the playback quality of video media stream. In light of this special request on receiving real time video media stream, a design of buffer based on time driver is proposed in this paper. After a test, this buffer has good results both on smoothing video show and on solving the packet drop and packet disorder problems brought from the poor network environment. This design can be widely applied in the client systems receiving real time video media stream. |
