Abstract

A robust video transmission technique that protects video signals over wireless channels is proposed in this work. First, we present new packetization and concealment methods for compressed video data. Second, the loss of each packet is quantitatively measured under this normative concealment method. More specifically, the encoder associates each packet with the mean square error between the error-free reconstruction and the concealed reconstruction. Third, a channel code rate is adaptively allocated to protect each packet so that the expected mean square error is minimized subject to a constraint on the overall bit rate. Extensive simulations show that the jointly designed video codec provides acceptable image quality in a high bit error rate environment. Besides, the proposed algorithm can be applied to real time video transmission applications, since its computational complexity is very low.
