Abstract:
There is provided a file generation apparatus and a file generation method as well as a reproduction apparatus and a reproduction method by which a file in which quality information of a depth-related image at least including a depth image is efficiently stored can be managed. An MPD file generation unit generates an MPD file. The MPD file is a management file that manages a file in which quality information representative of quality of a plurality of depth-related images including at least a depth image is disposed in a form divided in a plurality of tracks or subsamples and the management file in which a correspondence relationship between the respective tracks and associationID that specifies the depth-related images is described. The present disclosure can be applied when a segment file and an MPD file of a video content are distributed, for example, in a method that complies with MPEG-DASH.
