MOTION-CONSTRAINED CONTROL DATA FOR TILE SET Russian patent published in 2018 - IPC H04N19/577 H04N19/70 H04N19/46 H04N19/167 H04N19/174 G06T9/00 

FIELD: data processing.

SUBSTANCE: invention relates to transmission of overhead and more particularly to processing of encoded data. System for processing encoded data implements an encoder system configured to perform operations comprising: encoding multiple pictures to produce encoded data, wherein each of the multiple pictures is partitioned into multiple tiles; and outputting the encoded data along with control data that indicates that inter-picture prediction dependencies across specific boundaries are constrained for a given tile set, wherein the given tile set is parameterised in the control data as one or more tile regions covering the one or more tiles of the multiple tiles, wherein the control data include a quantity parameter indicating the number of tiles in the tile set, and syntax elements that indicate the location of the tile region in the multiple pictures.

EFFECT: simplifying picture processing through the use of control data.
