METHOD OF ENCODING AND DECODING IMAGES, DEVICE FOR ENCODING AND DECODING AND RELEVANT COMPUTER PROGRAMMES Russian patent published in 2017 - IPC H04N19/91 H04N19/50 G06T9/00 

FIELD: physics, communication.

SUBSTANCE: invention relates to technologies of encoding / decoding video data. The decoding device is proposed comprising: a means for receiving a bitstream representing at least one encoded image. The device also comprises a means for identifying the predetermined plurality of blocks subsets of said at least one encoded image from the bitstream, each subset of said plurality comprising at least a series of consecutive blocks. The device also comprises a means for entropy decoding of the first number of consecutive blocks in the first subset of blocks and for entropy decoding of a second number of consecutive blocks in the second subset of blocks.

EFFECT: invention provides more efficient data stream decoding due to improved adaptation of the encoded data stream to a particular kind of decoding.
