The development of ultra-broadband IP network has enabled video transmission over an IP network, and this provides the next-generation video transmission method for broadcasting stations. Standardized and stable IP technology enables broadcasts such as multicast over a low-cost network system. Video transmission of live TV broadcasts requires high-quality and low-delay video. In this paper, we propose IP video transmission method for uncompressed HDTV video that meets the high quality and low-delay requirements. And our video transmission system was applied to TV broadcasts, and stably used for half a year. We describe the knowledge and experience that we obtained through the development and use of technologies for producing and broadcasting TV content.
