Abstract: 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.

Abstract: 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.

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: 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.

Abstract: 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.
