ENTRY POINTS FOR FAST 3D TRICK PLAY Russian patent published in 2015 - IPC H04N19/00 H04N13/00 G06T15/08 

FIELD: physics, video.

SUBSTANCE: invention relates to video data processing means. The method includes generating an entry point table; defining entry points in the video data stream with a certain a distance in time from each other to facilitate trick play; storing the defined entry points in the entry point table by storing addresses thereof. In the method, the video data stream comprises a plurality of sub-streams representing one stream of 3D video data and comprises a 2D sub-stream which comprises an independently encoded 2D version of the 3D video data and an auxiliary sub-stream comprising a dependently encoded part of the 3D video data. In the method, defining the entry points comprises associating the entry point table with 3D video data by defining main entry points in the 2D sub-stream and auxiliary entry points in the auxiliary sub-stream.

EFFECT: high quality of display during 3D trick play.
