摘要
介绍了一种在以太网上传输数字电视MPEG-2传送流的组播网络技术。该技术采用GMRP协议完成以太网二层组播自动注册;用虚拟局域网方法将数字电视网与计算机网络隔离;用以太网的优先级设置保证数字视频流的服务质量;用基于MAC帧传输TS的方法保证处理速度。给出了基于以太网传输数字电视MPEG-2传送流的方法,并介绍了用FPGA实现本方案的过程。
A muhicast network technology for transporting MPEG-2 transport stream of digital TV based on Ethernet is introduced. GMRP completes automatic registration of Ethernet layer 2 multicast; Virtual LAN method separates digital TV network from computer network; Ethernet prior configuration guarantees QoS of digital video stream; and a technique for transporting TS based on MAC frame guarantees processing speed. A method for transporting digital TV program in Ethernet is given, and a process for achieving the goal in FPGA is introduced.
