  • Method and apparatus for providing stream linking in audio/video disk media
    Patent number: 9911462
    Abstract: A method and apparatus for providing stream linking in audio/video disk media is disclosed. The present invention sets-up an audio/video stream on a disk drive, uses read and write commands for accessing contiguous data and, given an established stream, establishes a linked stream by sending a linked stream request with the number of a primary stream to the drive. The new stream inherits the beginning and ending addresses of the primary stream. Passed pointer detection is enabled for linked stream pointers passing primary stream pointers.
