【摘要】 文章介绍了一种对网络多媒体数据的实时接收、解码和播放的方法,并广泛应用在基于DSP信源压缩的多媒体监控系统中。监控系统采用MPEG-1编解码国际标准,下位机主要进行信源数据的采集、数字化压缩和以太网传输等工作。上位机主要利用WinSock技术和DirectShow技术进行网络多媒体数据的实时接收、解码和播放等工作,并使用了一种类似"循环队列"的"双缓冲队列"技术来进行内存中多媒体数据的缓冲工作。更多还原

【Abstract】 In this paper,a method for receiving, decoding and playing the real-time multimedia data transmitted in the Ethernet is introduced. The method has been applied well in the multimedia surveillance system based on the source compression with DSP. The MPEG-1 encoding and decoding international standard is used in the system. The submitted-machines are used to compress the acquired source data and send them to the Ethernet. The WinSock and DirectShow technologies are used in the main-machine introduced in this paper to receive, decode and play the real-time multimedia data in the Ethernet. A "double-buffer queue" like "cycle queue" technology is also used to store the multimedia data in the memory of the main-machine.更多还原
