Efficient coding of video data in the presence of video annotations
Systems and methods for coding a video to be overlaid by annotations are devised. A motion compensated predictive coding is employed, wherein coding parameters of video pixel blocks are determined based on the pixel blocks' relation to the annotations. A decoder decodes the video and annotates it based on metadata, obtained from the coder or other sources, describing the annotations' appearance and rendering mode.
