Data processing method and device for adaptive image playing

A data processing apparatus comprising:

• a generator generating an uncompressed data signal;
• and
• a transmitter transmitting the uncompressed data signal and InfoFrame,
• wherein the InfoFrame is a data transmission structure for transmitting information to a sink device that receives the uncompressed data signal, and includes a color volume descriptor describing information on a color volume,
• wherein the InfoFrame includes type information for indicating a type of the color volume according to a target of the color volume, color volume type information for indicating the type of the color volume according to a method for defining the color volume, and color space type information for indicating a type of a color space in which the color volume is expressed,
• wherein the color volume corresponds to one of a content color volume for indicating a color volume of a content in accordance with the type information, a mastering display color volume for indicating a color volume of a mastering display used for mastering of the content, a display color volume for indicating a color volume of a display recommended for playback of the content, and a container color volume for indicating a color volume of a container transmitting the content, and
• wherein the color volume corresponds to one of a first method for defining the color volume through color gamut and luminance range in accordance with the color volume type information, a second method for defining the color volume through a color boundary of a color plane according to a luminance level, and a third method for defining the color volume through a color boundary according to a color space in which the color volume is expressed.
