Video communication through wireless channels is still a major problem due to the limitations in bandwidth and the presence of channel errors. The other limitations within the mobile networks is low transmission bit rate which demands the reduction of the used video resolution and a high efficient video compression technique. Video transmission in wireless environments is a challenging task calling for high-compression efficiency as well as a network-friendly design. The network-friendly design of H.264/AVC is addressed via the network abstraction layer that has been developed to transport the coded video data over any existing and future networks including wireless systems. Exploiting this feature, we present a modified temporal-spatial error concealment algorithm for H.264 coded video. Simulations were carried out in computing environment Matlab using the standard video-sequences.
