Broadcasters are converting their live program production facilities to Internet Protocol (IP)-networks. The introduction of IP-networks has many possibilities such as cost reduction and remote production, and various efforts are underway. At present, the main issue is to consider the construction of equipment for 2K high definition television (HDTV), and it is expected that the introduction of higher speed 4K and 8K ultra-HDTV (UHDTV) will accelerate in the future. In video transmissions using high-speed signals, video degradation due to packet loss such as random loss and burst loss that occurs in the network-switch of a transmission path becomes a problem. In the case of 4K and 8K UHDTV transmissions, since the number of packets per unit time increases, this problem becomes more serious. Therefore, it is indispensable to apply quality compensation technology to achieve high-quality video transmission. Forward error correction (FEC) using erasure codes is a key compensation method for recovering lost packets at the receiving side in unidirectional transmission. In this paper, we propose an exclusive OR-based FEC method with improved burst loss tolerance. Using this method, we have developed a transmission device for uncompressed 8K UHDTV signals over IP-networks using 100-Gb/s Ethernet packets. Experimental and simulation results clarified that the proposed method can improve the number of recoverable packets at the time of burst loss to twice as many as the conventional Pro-MPEG FEC method.

基于对角异或的 FEC 方法提高 4K/8K UHDTV 传输的突发丢失容限


广播公司正在将其现场节目制作设施转变为互联网协议 (IP) 网络。 IP网络的引入具有许多可能性，例如降低成本和远程生产，并且正在进行各种努力。目前主要问题是考虑2K高清电视（HDTV）的设备建设，预计未来将加速引入更高速的4K和8K超高清电视（UHDTV）。在使用高速信号的视频传输中，由于传输路径的网络交换机中发生的诸如随机丢失和突发丢失之类的分组丢失而导致的视频劣化成为问题。在4K和8K UHDTV传输的情况下，由于单位时间的数据包数量增加，这个问题变得更加严重。因此，应用质量补偿技术来实现高质量的视频传输是必不可少的。使用纠删码的前向纠错（FEC）是单向传输中接收端恢复丢失数据包的关键补偿方法。在本文中，我们提出了一种独特的基于 OR 的 FEC 方法，具有改进的突发丢失容限。利用这种方法，我们开发了一种使用 100 Gb/s 以太网数据包通过 IP 网络传输未压缩 8K UHDTV 信号的设备。实验和仿真结果表明，该方法可以将突发丢失时的可恢复数据包数量提高到传统 Pro-MPEG FEC 方法的两倍。
