Abstract:
To support high-quality wireless video transmission over IP, error-resilience techniques are important because wireless video has more stringent requirements than general video transmission for packet loss, latency and jitter. The optimal forward error correction (FEC) code rate decision is a crucial procedure to determine the optimal source and channel coding rates to minimize the overall picture distortion when transporting video packets over packet loss channels. The conventional FEC code rate decision schemes using an analytical source coding distortion model and a channel-induced distortion model are usually complex and typically employ the process of model parameter training, which involves potentially high computational complexity and implementation cost. To avoid the complex modeling procedure, we propose a simple but accurate joint source-channel distortion model to estimate the channel loss threshold set for optimal FEC code rate decision.
