Layered video transmission based on genetic programming for lossy channels

This paper presents a novel robust layered video transmission design algorithm for noisy channels. In the algorithm, the 3D SPIHT coding technique is used to encode the video sequences for the transmission of each layer. A new error protection allocation scheme based on genetic programming is then employed to determine the degree of protection for each layer so that the average distortion of the reconstructed images after transmission can be minimized. Simulation results show that, subject to the same amount of redundancy bits for error protection, the new algorithm outperforms other existing algorithms where equal-protection schemes are adopted.
