FIELD: image processing.
SUBSTANCE: device has an installation section configured to set information on a buffer control parameter of each layer, indicating at least one of the parameters for controlling the decoder buffer is a parameter for executing the decoding process of only the corresponding level, and that the parameter for controlling the decoder buffer is a parameter for executing the decoding process of the corresponding layer and the lower layer; an encoding section configured to encode an image having at least one layer and generate a bit stream; and transmitting section, configured to transmit buffer control parameter information set by the setup section and a bitstream generated by the encoding section.
EFFECT: technical result is enabling execution of decoding process in proper period of time.
