Abstract
Multiple different versions of media content are contained in a single package of audio-video media content, using compression algorithms that reduce storage and bandwidth required for storing multiple full-resolution versions of the media. Portions of individual frames are replaced during playback so that only the pixels that differ between versions need to be stored.
