    Abstract: The present disclosure relates to an information processing apparatus and method that make it possible to suppress subjective a decrease in quality when a bit rate is low. A video metadata generation unit, and an audio metadata generation unit generate stream selection support information, the stream selection support information being metadata indicating information regarding a parameter to be preferentially maintained, the parameter being determined in accordance with content of content data, and a communication unit transmits the generated metadata and pieces of content data of a plurality of bit rates. The present disclosure is applicable to, for example, a distribution system including a file generation apparatus, and a reproduction terminal.

    Abstract: The present technology relates to an image processing apparatus and a file generation apparatus that make it possible to appropriately reproduce a BV content.An image processing apparatus includes: a file acquisition unit that acquires a file having a management region where information for management of a 3D object content is stored and a data region where a track in which streams included in the 3D object content are stored is stored, group information for selection, from a plurality of the streams included in the 3D object content, of the stream appropriate for reproduction of the 3D object content being stored in the management region; and a file processor that selects a plurality of the streams to be used for reproduction of the 3D object content on the basis of the group information. The present technology is applicable to a client apparatus.

    Abstract: There is provide 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.

    Abstract: To resolve or at least reduce trouble related to mismatch between a dynamic range of an HDR video signal and peak luminance of a display. Provided is an image processing apparatus including: a transformation unit configured to transform image signals based on a signal scheme of fixedly handling a display luminance level of reference white into display signals by executing gamma transformation so that the display luminance level of the reference white is maintained using a parameter decided on a basis of a peak luminance level of a display.

    Abstract: The present disclosure relates to an information processing apparatus and an information processing method, which enable efficient description of depth representation information in an MP4 file. A file generation unit samples and arranges an elementary stream obtained by encoding a depth image including pixel values, which are obtained by quantizing depth information indicating a position of each pixel in a depth direction, as well as groups samples with the same depth representation information regarding the depth image and generates the MP4 file in which the depth representation information of each group is described. The present disclosure can be applied to, for example, a file generation apparatus and the like.
