In this paper, the problem of real time transmission of compressed video over a variable UWB channel is investigated. The main goal is to create joint compression and transmission scheme (jpeg progressive + ARQ protocol) that will provide the required level of PSNR and probability of lost rows in reconstructed frames. For this purpose an ARQ protocol for multi stream video delivery is developed. Also a special model is presented to find the optimal parameters (packets sizes, number of slices) of the joint coding scheme minimizing the number of dropped rows and maximizing PSNR of reconstructed frame. The suggested solution was developed for Cable Replacement program and can be used with existing UWB PHY/MAC.
