Abstract :
The interest that has been shown in the provision of mobile communications systems has led to the study of real time video traffic over wireless and other error prone networks. Many of the papers in this area employ the MPEG-2 video coding algorithm and provide experimental results of the decoded image quality derived from using only the effect of cell loss on the MPEG-2 video layer. In a practical transmission scheme, this video information is combined with the audio and synchronisation information in the MPEG-2 systems layer. Results presented in this paper show that the omission of the effect of cell loss on the MPEG-2 systems layer may lead to a significant underestimation of the degradation in the quality of the decoded video
