XOR-Based FEC to Improve Burst-Loss Tolerance for 8K Ultra-High Definition TV over IP Transmission
Junichiro Kawamoto, Takuya Kurakake · 2017
We are currently developing a 4K and 8K ultra-high definition television (UHDTV) over Internet Protocol (IP)-transmission system for live program production in broadcasting-station networks using high-speed Ethernet. If network-switch devices in a transmission path discard transmitted packets in this system, block noise is generated at recovered video signals on the receiver side, which makes it difficult to ensure stable video transmission. In particular, burst loss of packets significantly degrades video-image quality compared to random loss. Forward error correction (FEC) using an erasure code is a key technology to recover lost packets at the receiver in unidirectional transmission. In this paper, we propose an exclusive OR-based FEC method for improving burst-loss tolerance and developed transmission equipment for an uncompressed 8K UHDTV signal over IP-transmission using 100-Gb/s Ethernet packets implemented with the proposed method. The experimental and simulation results indicate that the proposed method can improve burst-loss tolerance to twice that of a conventional method.
