In the process of video transmission, packets loss may lead to the reconstruction distortion. When network coding is used for video transmission, the original error will cause propagation in the following nodes. To reduce the impact of error propagation, a random linear network coding (RLNC) based on the rate distortion is proposed to realize reliable video transmission. The method finds out the optimal...
In order to further improve the performance of rate control in H.264, a pixel-level rate control algorithm for the optimal prediction residual is proposed. Firstly, this proposed algorithm determines whether discrete cosine transform (DCT) should be applied to the macro block according to the simple rate distortion optimization (RDO) mode. Then quantization parameter (QP) is determined through a new...
