VIDEO ENCODING DEVICE, VIDEO DECODING DEVICE, VIDEO ENCODING METHOD, VIDEO DECODING METHOD AND PROGRAMME Russian patent published in 2015 - IPC H04N19/46 H04N19/61 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to computer engineering. A video decoding device includes extraction means for extracting information on the size of the pulse-code modulation (PCM) unit from a bit stream; means of determining the size of the PCM unit for determining the minimum size of the PCM unit for parsing the PCM header, based on the information on the size of the PCM unit; means of parsing the PCM header for parsing, from the bit stream, the PCM header, the unit of which has a value equal to or greater than the minimum size of the PCM unit; entropy decoding means for parsing converted image data in the bit stream; PCM decoding means for decoding, by decoding PCM data, an image in the bit stream; and decoding control means for controlling the entropy decoding means and the PCM decoding means based on the PCM header.

EFFECT: high quality of compressed video.
