Studies on live program production systems using Internet Protocol (IP) communications technology at broadcast stations are progressing. IP technology is suitable for broadcast stations aimed at diversification of broadcasting services such as 4K/8K UHDTV due to its ease of multiplexing and ability to perform bidirectional communication, along with the decrease in cost per bit. Therefore, live program production systems using IP technology are considered an effective means for implementing broadcasting systems more efficiently and flexibly. Remote production is attracting attention as a new style of live program production using IP. In remote production, broadcast stations and venues are connected by IP network, and programs are remotely produced from the broadcast station side. To enable remote production, it is necessary for both the venue and the broadcast station to share, in real-time, high-quality video taken at the venue. It is also required to bidirectionally communicate signals other than video/audio that are necessary for program production, such as control and communication line signals. To realize 8K remote production, we have developed a lightweight compressed 8K over IP transmission device. In this work, we describe its functions and report experimental results on multi-channel audio remote production with 8K video and real-time 8K camera control on a 1000-km IP network.
