PADDING OF SEGMENTS IN CODED SLICE NETWORK ABSTRACTION LAYER UNITS Russian patent published in 2016 - IPC H04N19/70 H04N19/436 

FIELD: information technology.

SUBSTANCE: method of encoding video data, comprising dividing a picture into a plurality of picture partitions, the picture having a plurality of tree blocks, the picture partitions associated with non-overlapping subsets of the tree blocks of the picture; and generating a coded slice network abstraction layer (NAL) unit which includes encoded representations of the tree blocks associated with a slice of the picture, the encoded representations of the tree blocks grouped within the coded slice NAL unit into segments associated with different picture partitions, wherein one or more of the segments are padded such that each of the segments begins on a byte boundary, said segments including a given segment; and generating a coded slice network abstraction layer (NAL) unit comprises performing a padding operation which appends bits to the given segment if the next tree block is inside the slice and is associated with a different picture partition from the given segment.

EFFECT: high coding efficiency by providing parallel processing.
