FIELD: physics.
SUBSTANCE: invention relates to encoding and decoding video data. Technical result is provided due to the fact that video decoder can determine, based on syntax elements in bit stream, which contains encoded representation of video data, residual quantized samples of the video data unit, determine quantized residual values based on the residual quantized samples. After determining the quantised residual values, the video decoder may inversely quantise the quantised residual values. Video decoder can generate predicted values by performing internal prediction for a block using unfiltered samples from boundary samples of the upper or left block and can restore the initial sampled values of the block based on inverse quantised residual values and predicted values.
EFFECT: high efficiency of encoding and decoding video data.
