摘要
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。
The video streaming over the Internet is a new type of service,whose requirements of real time and strong ability of error resilience edmand the better transmission channels.Based on analyzing structure charateristics of MPEG 2 code streaming,and cooperating with real time transmission protocols,a new structure of peer to peer digital video system is presnted and an implementing resolution of hardware scheme is given.Experimental results show that the system has excellent quality when used to transmit video streaming inside local area network.
