Patent ID: 7949229

Claim:
A method of synchronizing media data used in authoring a Blu-ray disc (BD), the method comprising: receiving BD media data having at least an audio portion and a video portion, the audio portion formed from at least one audio stream and the video portion formed from a plurality of video streams, wherein a discontinuous input timecode having at least one discontinuity is associated with said plurality of video streams, wherein said at least one discontinuity has a start point and an end point, and is present between video streams; first generating an output timecode for the video portion that matches said discontinuous input timecode until the start point of said at least one discontinuity, and continue first generating said output timecode sequentially from a timecode subsequent to the end point of said at least one discontinuity, when a user specifies converting the discontinuous input timecode to a continuous output timecode; and second generating an output timecode for the video portion that matches said discontinuous input timecode until the start point of said at least one discontinuity, and continue second generating said output timecode that matches input timecode from a timecode subsequent to the end point of said at least one discontinuity, when the user specifics maintaining the discontinuous input timecode as a discontinuous output timecode.
