摘　　要：在广播电视行业,4K、8K超高清技术的快速发展,对于信号传输产生了更高的要求,需要更高的带宽和更低的延迟。在这种情况下,传统的串行数字接口(Serial Digital Interface,SDI)技术已经不能满足,需要向网际互连协议(Internet Protocol,IP)化转化。针对SDI技术的局限性以及IP技术的优势进行阐述,发现IP化不仅可以提升传输效率、降低传输成本,还可以促进广播电视行业的创新和发展。In the broadcasting and television industry,with the rapid development of 4K and 8K ultra high definition technology,higher requirements have been placed on signal transmission,requiring higher bandwidth and lower latency.In this situation,traditional Serial Digital Interface(SDI)technology is no longer sufficient and needs to be converted to Internet Protocol(IP).This article mainly elaborates on the limitations of SDI technology and the advantages of IP technology.It is found that IP-based can not only improve transmission efficiency and reduce transmission costs,but also promote innovation and development in the broadcasting and television industry.

关 键 词：串行数字接口(SDI) 网际互连协议(IP) 传输效率
