The lossless encoding syntax element indicates that the current video data block is encoded using a lossless encoding mode. Herewith the lossless syntactic element is separate from the quantization parameter values (QP); it is determined that the current video data block is a current quantized block based on the size of the current video data block; a zero value of the delta-quantization parameter (dQP) is assigned for the current quantized block. The dQP value is a difference between the QP value and the QP predictor value; the value of the QP for the current quantized block based on the assigned dQP value and the QP predictor is determined; and the current quantized block is decoded in accordance with the lossless encoding mode and a certain QP value.
EFFECT: possibility to avoid potential mismatches of the encoder, decoder.

SUBSTANCE: method for encoding a digital image is proposed. According to the method, the digital space of the digital image is converted, the image is divided into blocks with a size of the P×N elements, each block with a size of the P×N elements is adaptively encoded, a bitstream is formed. Herewith the adaptive coding is performed by defining a basis of the orthogonal conversion, and to determine the basis of the orthogonal conversion, the right-hand matrix of the orthogonal conversion with a size of N×N and the left-hand matrix of the orthogonal conversion with a size of the P×P elements are calculated.
EFFECT: increasing the compression ratio without reducing the quality of the restored image at the reception by eliminating the pre-formed wavelet-basis library and forming an orthogonal conversion basis directly from the original image block itself.
