| Abstract: | A kind of network video server based on MPEG -4 is designed to meet the need of digitalized network video monitoring system. In this design, collected audio and video data is compressed through the MPEG- 4 real -time video compression cards based on DM642, compressed audio and video data is saved into the memory of the server by the ring queue, and the transmission problem of network data is dealt with by the multi -thread technology and transmission mechanism, which effectively restrain the phenomena such as unclear image, asynchronous audio and video, the mosaic, at the same time, which guarantee real- time and synchronized audio and video when the clients watch real- time video. |
