Abstract
and stable broadcasting service. As a representative SDI signal, it consists of high definition-SDI (HD-SDI) 12) signals with a transmission speed of 1.5 Gb/s used in the 2K broadcasting service, and in recent years, faster 12G-SDI 13) signals have also been standardized. An HD-SDI can transmit one 2K HDTV Abstract Studies on live program production systems using Internet Protocol (IP) communications technology at broadcast stations are progressing. 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.
