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.

[论文]实现远程直播制作的轻量级压缩8K超高清电视IP传输设备的研制

稳定的广播服务。作为SDI信号的代表，它由2K广播业务中使用的传输速度为1.5 Gb/s的高清SDI (HD-SDI) 12)信号组成，近年来，更快的12G-SDI 13)信号也被标准化。摘要利用互联网协议(IP)通信技术在广播电台进行节目直播制作系统的研究正在进行中。远程制作作为一种利用IP进行直播节目制作的新形式，正受到人们的关注。在远程制作中，广播站和场馆之间通过IP网络连接，由广播站端远程制作节目。为了实现远程制作，场馆和广播站都需要实时共享在场馆拍摄的高质量视频。还需要双向通信节目制作所必需的视频/音频以外的信号，如控制和通信线路信号。为了实现8K远程制作，我们开发了一种轻量级的压缩8K over IP传输设备。在本文中，我们描述了它的功能，并报告了在1000公里的IP网络上进行8K视频和实时8K摄像机控制的多通道音频远程制作的实验结果。
