Patent ID: 8867890

Claim:
A method for authoring a pre-recorded optical storage medium after finalization of a main AV multiplex, said method resulting in an optical storage medium for out of multiplex bit-stream reading wherein an out of multiplex semantic provides the ability to playback AV streams combining streams coming from the optical storage medium and via internet or another storage medium, a description for out of multiplex AV material comprises different files including navigation files and stream files, the navigation files provide all entry points for navigation within the stream files and a playback element on the optical storage medium is described, in a higher layer of the navigation files, by means of a List_of_PlayItems with a number of PlayItem elements and a number of SubPlayItems arranged within the List_of_PlayItems structure in parallel to the PlayItem elements, each of a PlayItem structure and a SubPlayItem structure comprises a StreamFile describing a link to an elementary stream file, a Start_time describing the presentation start time of the respective structure within the StreamFile and an End_time describing the presentation end time of the respective structure within the StreamFile, and each SubPlayItem structure further comprises a SubStream_type which defines the type of the respective structure, the SubStream_type being one of: an auxiliary audio stream path for audio dubbing, a video stream path, an audio stream path, a subtitle stream path, a graphics stream path and an auxiliary transport stream path, said method comprising the step of: independently preparing, on an external source, an auxiliary AV multiplex wherein a StreamFile of at least one SubPlayItem describes a link to an elementary stream multiplexed in said auxiliary AV multiplex.
