Development of Uncompressed 8K Super Hi-Vision Signal Transmission over 100 Gigabit Ethernet

摘要

In order to share 8K Super Hi-Vision programs in broad-casting stations, we have been developing a transmission system using Ethernet technology. In this paper, we propose a clock recovery and control method for 8K signals as part of an uncompressed 8K signal transmission system over 100 Gigabit Ethernet with effective usage of transmission capacity as well as low jitter and low latency. We report the results of an examination using a test bed implement-ing the proposed method, in which the latency was 459 μs, frequency deviation was ±1ppm or less, and which satisfled the standard value of jitter specifications.
