Dynamically reconfigurable architecture for real time adaptation of H264/AVC-SVC video streams

This paper presents a dynamically reconfigurable architecture for real time video adaptation in order to address different terminals and bandwidths. This architecture is designed to adapt a compressed stream in advanced video coding standard (H264/AVC) using the scalable extension (H264/SVC) with additional refinement in quality transcoding. A low quality and high quality streams requiring different architectures are considered to validate the proposed reconfigurable architecture. Simulation results and hardware implementation have shown the capabilities of this architecture to transcode high definition video in real time. In addition, a significant gain has been obtained in terms of silicon area using dynamic partial reconfiguration.
