Technological development and standardization of contribution signals to IP (Internet Protocol) with low latency for program production are progressing. In IP transmission, transmission packets may be continuously discarded (burst loss) due to occurrence of congestion in a network switch device arranged on a transmission path. Since burst loss locally occurs in the video signal to be recovered on the receiving side, quality degradation of the recovered video is larger than random erasure. As a technique for restoring lost packet generated in the transmission path, an erasure correction code using exclusive OR operation considering low latency property is standardized by SMPTE (conventional method). We have proposed and studied methods to improve the burst loss tolerance by improving the construction method of the conventional method. In the proposed method, the burst loss tolerance can be improved about twice as much as the conventional method or the erasure correction code that improves burst loss tolerance by interleaving, while maintaining the same random discarded characteristic, in the case where the latency is not greatly. In this report, we outline the construction method of the erasure correction code of the proposed method, and the performance evaluation results we have done so far, and describe the effectiveness of the proposed method. |
