A reproduction apparatus, a reproduction method, a program, and a recording medium configured to stabilize display upon starting of reproduction of an HDR video stream. The reproduction apparatus according to one aspect of the present technology decodes, in a case where a first content including a first HDR video stream to which dynamic metadata including luminance information of a unit of a video frame is added and a second content including a second HDR video stream to which the dynamic metadata is not added and with which static metadata including luminance information of a unit of a content is associated are included in reproducible contents and the second content is to be reproduced, the second HDR video stream, and adds the dynamic metadata to video data obtained by the decoding and outputs resulting data to a display apparatus. The present technology can be applied to a Blu-ray Disc player.

Reproduction apparatus, reproduction method, program, and recording medium

To enable MMT format data to be recorded as BDAV format data in a medium, and a list of video-recorded contents to be displayed and reproduced by an application for BDAV. Data to be recorded in a playlist or clip information file defined in a BDAV format is extracted from MMT format data input on a broadcast wave or the like thereby to generate a data file thereof. For example, data applied to display a list of video-recorded contents is extracted from MMT-SI or TLV-SI in the MMT format data and recorded in the playlist or clip information file.

Information processing apparatus, information processing method, and program

A configuration is implemented that converts MMT format data to MPEG-2 TSV format data for recording onto medium, thereby permitting copy control in compliance with the initial copy control information. MMT format data with copy control information set therein is input and converted to MPEG-2 TS format data for re-cording onto information recording medium. The copy control information recorded in the service description table (MH-SDT) stipulated by the MMT format is acquired and, in accordance with predetermined conversion rules, used to generate the copy control information for recording to the program map table (PMT) stipulated by the MPEG-2 TS. For example, the EPN and CCI values to be recorded to the PMT are determined in accordance with the conversion rules.

Information processing apparatus, information recording medium, and information processing method

A configuration capable of recording MMT format data on a medium as BDAV format data and performing copy control according to the original copy control information is achieved. The MMT format data, for which copy control information is set, is input and recorded on an information recording medium as BDAV format data. As record data, (a) a stream file including a packet string in which the MMT format data is stored, and (b) copy control information corresponding to the stream file, in which the copy control information corresponding to the MMT format data is reflected, are generated and recorded as an additional header of a packet included in the stream file or as another file.

Information processing apparatus, information recording medium and information processing method

A configuration is realized that allows reproduction control on the basis of age at the time of reproduction by recording information regarding age permitted for reproduction corresponding to media recorded content. A clip AV stream file storing content to be reproduced acquired from input data including MPEG-2 TS format data or MMT format data and information regarding age permitted for reproduction corresponding to content acquired from the input data are placed into a playlist file, a clip information file, a usage control information file, or other file and recorded in media. A reproduction apparatus reads the information regarding age permitted for reproduction corresponding to the content to be reproduced from the playlist file or other file and compares the information regarding age permitted for reproduction with user's age information, thus allowing for content reproduction to be controlled.

Information processing apparatus, information recording medium, information processing method, and program

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.

Information processing device, and information processing method, and program

There is provided an information processing apparatus, an information processing method, a recording medium, a playback apparatus, a playback method, and a program that are designed to prevent an unnatural change in luminance during random access. The information processing apparatus according to one aspect of the present technology generates dynamic metadata including information regarding luminance of a picture, and encodes HDR video data such that the dynamic metadata is added to each picture serving as a random access point. For example, the dynamic metadata can be allowed to be added to the first picture of a GOP, the first picture serving as the random access point during fast-forward playback/rewind playback or cueing playback. The present technology can be applied to a Blu-ray (registered trademark) Disc player.

Information processing apparatus, information processing method, recording medium, playback apparatus, playback method, and program

There is provided a reproduction apparatus, a reproduction method, a program, and a recording medium that can prevent an unnatural change in luminance in a case where other information is displayed by being superimposed on a video. A reproduction apparatus according to an aspect of the present technology receives a video stream to which dynamic metadata including luminance information of a picture has been added, and in a case where predetermined information is superimposed and displayed on the picture, adds metadata indicated by a flag indicating the metadata used for luminance adjustment while the predetermined information is superimposed and displayed to the picture constituting the received video stream, and outputs the picture to which the metadata has been added to a display apparatus. The present technology can be applied to a Blu-ray (registered trademark) Disc player.

Depending on the type of an image stored in an information recording medium and display function information about a display device, an image to be displayed is acquired from a recording medium and output to the display device. A data processing unit configured to execute data reproduction from the information recording medium receives, from the display device configured to perform reproduction data display processing, image display function information such as type information about a VR image to be displayed, acquires, from a database file recorded on the information recording medium, VR identification information indicating which one of a VR image of type 1, a VR image of type 2, and non-VR image other than the VR images is included in the information recording medium, reads, from the information recording medium, image data that can be displayed on the display device based on a result of comparison between the acquired display device function information and VR identification information, and outputs the image data to the display device.
