Information Processing Device and Method, and Program, for Gamut Conversion of Content

Abstract

An device, method and program may properly perform gamut conversion of content and be applied to a gamut conversion device. A restoration conversion state confirming unit performs confirmation such as gamut conversion state of image data read out from an optical disc and the existence or not of restoration metadata. An information exchange unit communicates with an output device via a communication unit and performs information exchange such as the existence or not of restoration processing functionality and gamut conversion functionality and the like. A determining unit determines whether or not restoration processing is performed with a playing device based on information obtained by the restoration conversion state confirming unit and the information exchange unit. Similarly, the determining unit determines whether or not to perform gamut conversion processing with the playing device based on information obtained by the restoration conversion state confirming unit and the information exchange unit.

1 . An information processing device comprising:
 restoration metadata generating means to generate restoration metadata that includes data referenced in restoration processing which returns at least a portion of the gamut of an image subjected to gamut conversion to the state before gamut conversion; and   associating means to associate said restoration metadata generated with said restoration metadata generating means to said image.
