Patent ID: 8381254

Claim:
A non-transitory computer-readable storage medium containing video, audio and/or other data, comprising: a basic AV MPEG-2 transport stream of multiplexed elementary streams; a navigation file comprising a basic stream path of consecutive descriptors pointing to parts of said basic AV MPEG-2 transport stream, wherein said descriptors define the arrangement in time for playing back said parts of said basic AV MPEG-2 transport stream; the navigation file further comprising multiple sub stream paths of consecutive descriptors existing in parallel to said basic stream path, said sub stream paths of descriptors pointing to data streams or parts of data streams of which at least one data stream is located out of the basic AV MPEG-2 transport stream on one of the computer readable storage medium and an external data source, wherein each of said sub stream paths is of one of: a video stream path type, an audio stream path type, a subtitle stream path type and a graphics stream path type; and an indication of the stream path type of each of said sub stream paths; said descriptors of at least one data stream, which is originating from an external data source, pointing at said basic AV MPEG-2 transport stream thus allowing binding of the corresponding sub stream path to said basic AV MPEG-2 transport stream.
