Abstract
Methods, systems, and computer readable media for encoding, distributing, and decoding multimedia files with interleaved video, subtitle, and audio chunks are provided. Multimedia files in accordance with embodiments of the present invention can contain multiple video tracks, multiple audio tracks, multiple subtitle tracks, data that can be used to generate a menu interface to access the contents of the file and ‘meta data’ concerning the contents of the file. In one embodiment, the generated ‘audio,’ ‘video’ and ‘subtitle’ chunks are interleaved so that the ‘audio’ and ‘subtitle’ chunks are located within the file prior to the ‘video’ chunks containing information concerning the video frames to which they correspond. In other embodiments, the ‘audio’ and ‘subtitle’ chunks can be located after the ‘video’ chunks to which they correspond. One embodiment of a multimedia file in accordance with the present invention includes a series of encoded video frames and encoded menu information.
