METHOD AND APPARATUS FOR ENCODING VIDEO USING TRANSFORMATION INDEX AND METHOD AND APPARATUS FOR DECODING VIDEO USING TRANSFORMATION INDEX Russian patent published in 2015 - IPC H04N19/169 H04N19/96 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to computer engineering. A method of encoding video which comprises determining a transformation unit, i.e., a data unit in which a current coding unit from among coding units is transformed, the coding units being data units in which a current video image is encoded, wherein the size of the transformation unit is determined independent of the size of at least one prediction unit which is a data unit in the current coding unit; transforming data of the current coding unit based on the transformation unit to encode the data of the current coding unit; and outputting the encoded data of the current coding unit, encoding mode information which indicates an encoding mode of the encoded data of the current coding unit, and transformation index information which indicates a structure of the transformation unit, as a bit stream.

EFFECT: high rate of encoding and decoding data.
