Using Placeholder Slices and MPEG-21 BSDL for ROI Extraction in H.264/AVC FMO-Encoded Bitstreams

The concept of Regions of Interest (ROIs) within a video sequence is useful for many application scenarios. This paper concentrates on the exploitation of ROI coding within the H.264/AVC specification by making use of Flexible Macroblock Ordering. It shows how ROIs can be coded in an H.264/AVC compliant bitstream and how the MPEG-21 BSDL framework can be used for the extraction of the ROIs.
