Applying Mpeg-21 Bsdl to the Jvt H.264/avc Specification in Mpeg-21 Session Mobility Scenarios

Video coding is present in a lot of multimedia applications such as video conferencing, digital storage media, television broadcasting, and internet streaming. However, offering universal access to video content is far from trivial when taking into account the diversity of current networks and terminals. In this paper, we will discuss how MPEG-21-based technology can be combined with a recently standardized video compression scheme, called JVT H.264/AVC. To be more specific, we demonstrate how MPEG-21 tools can be used to adapt an H.264/AVC bitstream dynamically to the requirements of a new terminal when transferring a multimedia session between devices. This can be seen as a first step in order to create a framework that allows optimal usage of video data in a network of heterogeneous terminals.
