| Abstract: | A network video server based on MPEG-4 was designed to meet the demand of a digital network video moni- toring system. Mpg-440-based MPEG-4 real-time video compression card is adopted to compress the captured audio and video data. The network data transmission are implemented with the multi threading technology and transfer mechanism while the circular queue is employed to achieve audio and video data compression, which can effectively restrain the unclear frames, desynchronized audio ~ video and mosaic phenomenon, and ensure the audio ＆ video real-time and synchronization when customers monitor. The experiments show that the scheme is cost-effective and can be used in the occasions which need audio and video surveillance. |
