FIELD: radio engineering, communication.
SUBSTANCE: device contains a receiver receiving and syntactically analyzing a bit flow of a coded image; a processor forming a coding unit which is included into a maximum coding block which has hierarchical structure by means of use of the information which indicates this hierarchical structure, syntactically analyzed from the accepted bit flow and forms one sub-block for prediction of a coding block from the coding block, by means of use of information on blocks of a prediction of the named coding block, an image recovery decoder.
EFFECT: higher efficiency of decoding of high-resolution images by determining the depth of the coding unit and the operating mode of the encoding tool according to data characteristics of the image.
