Abstract
In one embodiment, a system includes a compositor operable to receive a plurality of source video streams, each containing source images, and to convert each of the source video streams into source slice groups using flexible macroblock ordering (FMO). The compositor is further operable to add pad slice groups to the source slice groups to create a composite image, and reorder the source slice groups and pad slice groups into a single composite output stream. A device receives the single composite output stream and displays the composite image as a rectangular picture that has a size larger than that of any of the source images. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.
