Research on H.264/SVC Compressed Video Communication in 3G
The emerging of third generation mobile system (3G) makes various video applications in wireless environment possible. Scalable Video Codec (SVC) is the latest amendment for H.264/AVC that allows efficient, standard-based temporal, spatial, and quality scalability of video bit streams. The 3rd Generation Partnership Project (3GPP) video services, e.g. multimedia broadcast/multicast services (MBMS), packetswitched streaming service (PSS) etc., may greatly benefit from the adoption of SVC. And 3GPP has been gradually discussing to select SVC as one of the video codec tools in 3G. But not every key technology of SVC can be implemented because of 3G wireless networks characteristic of time variation, high bit error rate, limited bandwidth, and 3G mobile terminals limitation. So we analyze the key technology that adapts to 3G in this paper, and present compressed SVC video transmission in 3G wireless network together with the offline video transmission simulation in 3G wireless network. Here we modify the VCEG offline 3G transmission simulation model to transmit SVC byte stream format, moreover test and show the effect of SVC error resilient tools by using the model.
