Abstract :
The emerging of third generation mobile system (3G) makes conversational video transmission in wireless environment possible, and the latest 3GPP/3GPP2 standards suggest 3G terminals support H.264/AVC. Due to high bit error rate in wireless environment, error resilience schemes are necessary for 3G terminals. Moreover, according to 3GPP/3GPP2, 3G terminals support only part of error resilience tools of H.264/AVC. This paper lists various error resilience tools and analyzes their usability in 3G environment, and at the same time, some error resilience schemes are proposed. Performances of these error resilience schemes are tested using offline common test conditions. Experiments shows that, in 3G environment, encoding with simple FMO mode and extra intra block refreshing can achieve the best error correction ability, because this method can make full use of spatial correlation for intra predication and reduce the requirement of bit rate.
