摘　　要：基于以太网交换机的IP化架构,可以有效解决传统SDI接口,由于自身带宽等缺陷无法满足4K超高清信号传输的困难,设计一个SDI over IP架构,提供更大的带宽,满足4K信号的安全传输,而且信号吞吐量更加便捷,符合当下5G技术发展要求。The IP-based architecture based on Ethernet switches can effectively solve the traditional SDI interface.Due to its own bandwidth and other defects,it cannot meet the difficulties of 4K ultra-high-definition signal transmission.An SDI over IP architecture is designed to provide greater bandwidth and meet the secure transmission of 4K signals.The signal throughput is more convenient,which is in line with the current 5G technology development requirements.
