Abstract
A media bundle and one or more media bundle overlays allow modifying content that is to be played by a playback framework of an electronic device with multimedia content objects contained in the media bundle overlays without modifying the media bundle. A runtime data structure dynamically incorporates the multimedia content contained in the media bundle with multimedia content contained in the media bundle overlays. Manifest objects in the media bundle and some media bundle overlays describe multimedia content contained in the media bundle and the corresponding media bundle overlays. Multimedia content contained in the multimedia bundle overlays may supplement or replace multimedia content contained in the media bundle.
