FIELD: physics, video.
SUBSTANCE: invention relates to video data encoding and decoding techniques. Disclosed is a method of encoding a plurality of transform coefficients associated with residual video data during video encoding. The method includes a step of encoding information indicating significant coefficients for a plurality of transform coefficients according to a scanning order. Further, the method includes encoding information indicating the level of the significant coefficients of the plurality of transform coefficients according to said scanning order. Said scanning order for the significant coefficients corresponds to the scanning order for the levels of the significant coefficients.
EFFECT: matching the scanning order for encoding the transform coefficient significance mapping and for encoding transform coefficient levels.
