IMAGE PROCESSING DEVICE AND METHOD Russian patent published in 2018 - IPC H04N19/152 H04N19/187 H04N19/463 H04N19/70 

FIELD: information technology.

SUBSTANCE: invention relates to image processing. Image processing device comprises a receiving section, configured to receive a bitstream, obtained by encoding an image, having at least one layer, buffer management parameter information of each layer, indicating at least one of that a parameter for managing a decoder buffer is a parameter for performing a decoding process of only a corresponding layer and that the parameter for managing the decoder buffer is a parameter for performing a decoding process of a corresponding layer and a lower layer; and a decoding section, configured to decode the bitstream, received by the receiving section, and generate an image.

EFFECT: technical result is ensuring execution of the process of decoding a bitstream in the proper period of time by using buffer management parameter information of each layer.
