Internet网络视频流是一种全新的业务类型 ,它对传输信道的实时性、抗误码性有着更高的要求。在分析MPEG 2码流结构特性的基础上结合网络实时传输协议 ,提出了一种全新的端到端数字视频系统结构 ,并给出了其具体的视音频硬件实现方案。试验证明 ,在局域网中该系统传输视频流效果良好 ,接收质量高。
Internet network video streaming is a new type of service, which has higher requirements for the real-time transmission channel and error resilience. Based on the analysis of the structural characteristics of MPEG 2 stream, a new architecture of end-to-end digital video system is proposed based on the real-time network transmission protocol. The realization of video and audio hardware is also given. The experiment proves, this system in the local area network transmits the videoflow effect well, the receiving quality is high.
