摘　　要：专业无压缩音频信号在以太网中的传输技术已相当成熟,包括CobraNet和EtherSound等。但受到基础以太网功能的限制,很多实际应用功能无法实现,传输基础由以太网向三层IP网络发展肯定是个必然,只是配套的技术基础一直都还未成熟。当IEEE1588精密时钟协议出现以后,它的瓶颈就被打破了,由此拉开了三层网络传输专业音频信号技术时代的序幕。The technology for transmitting no compressed pro-audio signals using Ethernet including CobraNet and EtherSound is mature. Due to the limit of Ethernet itself, many applying functions can not be achieved. And it is inevitable that the transmission foundation will developed from Ethernet to the third level of OSI, IP networks. The problem to do this is the lack of pertinent accessorial technology. When the protocol of precise time synchronization of IEEE1588 is promulgated, the bottleneck is broken, and now...
