Abstract: A configuration capable of recording MMT format data in a medium as BDAV or SPAV format data and enabling the MMT format data to be reproduced is realized. MMT format data input via a broadcast wave or the like is input, and record data according to a BDAV format or an SPAV format is generated. A data processing unit generates an MMT format stream file storing the MMT format data as reproduction data and further generates a playlist file storing reproduction control information of the MMT format stream file and a clip information file.

Abstract: The present disclosure relates to an information processing apparatus, an information processing method and a program, and a recording medium that can generate graphics in colors in a predetermined dynamic range from the data of graphics of colors in a plurality of dynamic ranges. A processor identifies an SDR PDS that is an information item of a color in the SDR available for the graphics, an HDR PDS that is an information item of a color in the HDR available for the graphics from a graphics stream including the SDR PDS, and the HDR PDS, and a segment_type used to identify the SDR PDS and the HDR PDS on the basis of the segment_type. A CLUT management unit generates the SDR graphics on the basis of the SDR PDS identified by the processor. The present disclosure can be applied, for example, to a reproducing device.

Abstract: Image reproduction according to a display apparatus is realized by acquiring image information of an ultra-high definition (UHD) image from a playlist file or a clip information file. A data processing unit that performs a reproduction process of a disc recording data acquires a playlist file or a clip information file as a reproduction control information file corresponding to reproduction data recorded in a disc, determines whether or not an ultra-high definition (UHD) image is recorded in the disc based on recording data of such a file, and, in a case where the ultra-high definition (UHD) image is recorded in the disc, acquires image information of the ultra-high definition (UHD) image from the reproduction control information and controls output data for a display apparatus based on the acquired image information.

Abstract: The present technology relates to a reproducing device, a reproducing method, an information processing device, an information processing method, a program, and a recording medium, which are capable of reproducing an appropriate HDR video. The reproducing device of the present technology acquires reproduction management information in which a first flag indicating whether or not encoded data of a first HDR video which is mandatory when a video of a luminance range wider than a standard luminance range is included in content is included in the content and a second flag indicating whether or not encoded data of a second HDR video that is likely to be included in the content is included in the content are described. Further, the reproducing device reproduces the encoded data of the first HDR video or the encoded data of the second HDR video on the basis of the details of the first flag and the second flag and performance of a display serving as an output destination. The present technology can be applied to a Blu-ray disc player.

Abstract: It is possible to accurately and securely execute conversion from an MPEG-2TS format to an MP4 format. A data converting unit that executes format conversion from an MPEG-2TS format to an MP4 format sorts out TS packets storing video data from MPEG-2TS format data, selects a TS packet having a start code (SC) at the top of a payload on the basis of header information of the sorted out TS packets, and extracts payload configuration data other than the start code (SC) and sets the payload configuration data as configuration data of MP4 format data. The data converting unit determines, on the basis of, for example, a value of a transport priority set in a header of the TS packet, whether or not the TS packet is a TS packet in which a start code (SC) is set in a top region of a payload.

Abstract: The present technique relates to a file generation apparatus, a file generating method, a file reproduction apparatus, and a file reproducing method capable of enabling a user to enjoy an HDR image.HDR information designated by HDR designating information is acquired from a file storing a track of a stream including the HDR information which is configured with feature information representing features of luminance of an HDR (high dynamic range) image having a dynamic range higher than that of an STD (standard) image and conversion information representing a conversion rule of converting the one of the STD image and the HDR image into the other and a target track including the HDR designating information designating the HDR information which is to be applied to the target track of interest in the HDR information of the track. The present technique can be applied to the case of acquiring HDR information which is to be applied to an image of a subtitle or the like stored in, for example, an MP4 file.
