Image processing device and method

An image processing method using an image processing device, the image processing method comprising:

• setting whether or not to remove filler data from a bitstream for media data of a file including the bitstream generated by coding an image;
• setting an identification parameter used for identifying whether or not the filler data is removed;
• and
• generating the file without changing characteristics of Hypothetical Reference Decoded (HRD) parameters by retaining the filler data for the media data.

An image processing device comprising:

• a reception unit configured to receive media data of a file including a bitstream acquired by coding an image;
• and
• a decoding unit configured to read an identification parameter for identifying whether or not filler data is removed from the file received by the reception unit and to decode the bitstream by using a parameter managing a decoder buffer,
• wherein the file is generated without changing characteristics of Hypothetical Reference Decoder (HRD) parameters by retaining the filler data for the media data,
• wherein the reception unit and the decoding unit are each implemented via at least one processor.

An image processing method using an image processing device, the image processing method comprising:

• receiving media data of a file including a bitstream acquired by coding an image;
• and
• reading an identification parameter for identifying whether or not filler data is removed from the received file and decoding the bitstream by using a parameter managing a decoder buffer,
• wherein the file is generated without changing characteristics of Hypothetical Reference Decoder (HRD) parameters by retaining the filler data for the media data.

An image processing device comprising:

• a setting unit configured to set whether or not to remove filler data from a bitstream for media data of a file including the bitstream generated by coding an image;
• and
• a generation unit configured to generate the file without changing characteristics of Hypothetical Reference Decoder (HRD) parameters by retaining the filler data for the media data,
• wherein the setting unit and the generation unit are each implemented via at least one processor.

An image processing device comprising:

• a reception unit configured to receive a file generated using a setting whether or not filler data is removed from a bitstream for media data of a file including the bitstream generated by coding an image;
• and
• a decoding unit configured to read an identification parameter used for identifying whether or not the filler data is removed and to decode the bitstream by using the read parameter,
• wherein the file is configured so that characteristics of Hypothetical Reference Decoder (HRD) parameters do not change in the case that the filler data is removed from the bitstream by retaining the filler data for the media data, and
• wherein the reception unit and the decoding unit are each implemented via at least one processor.
