Abstract
An adaptive algorithm to adjust the Intra update rate of a video encoder is presented. As optimization criterion, the PSNR at the decoder after lossy transmission is used. Based on a model for the video encoder and error propagation at the video decoder the optimal Intra rate can be calculated for a given transmission channel analytically. In this paper it is shown how the parameters of these models can be measured adaptively during encoding. Thus, the Intra rate can be adjusted to changing channel conditions and sequence statistics. It is shown that a practical robust system can be built with the presented algorithm.
