Abstract: The present invention relates to a playback apparatus, a playback method, a program, a recording medium, and a data structure that enable interactive operations when playing back AV content. A controller 34 obtains an order list of audio stream numbers in advance. In response to an instruction to switch audio by a user, the controller obtains the audio stream number subsequent to the audio stream number which is being played back. It is then checked whether a stream that is found to be playable by the playback apparatus is included in a main clip or a sub clip, and the main clip referred to by the Main Path is read together with the clip in which the corresponding audio stream is multiplexed. Then, the audio stream file of the corresponding clip and the file to be played back included in the main clip are selected by the switches 57 through 59, and 77. The selected files are combined by a video data processor 96 and an audio data processor 97, and the combined data is output.

Abstract: The present disclosure relates to an image processing device and method which can accurately reproduce a dynamic range of an image. A value on a vertical axis corresponding to a maximum white level is a digital value of the maximum white level (white 800%) which is assigned to a developed image, and is set as max_white_level_code_value which is one of characteristics information of the dynamic range and is transmitted. A value on the vertical axis corresponding to a white level is a digital value of a white level (white 100%) which is assigned to a developed image, and is set as white_level_code_value which is one of characteristics information of the dynamic range and is transmitted. The present disclosure is applicable to, for example, an image processing device.

Abstract: A processing device for adding a subtitle to a three-dimensional (3D) image produced by left-eye and right-eye display patterns displayed on a display is disclosed. The processing device may include a video decoder configured to receive video content data representing content left-eye and content right-eye display patterns. The processing device may also include an audio decoder configured to receive sound data indicative of an audio volume level. Additionally, the processing device may include a subtitle decoder configured to receive subtitle data indicative of a subtitle display pattern, and modify the subtitle data based on the sound data. The processing device may also include a superimposition unit configured to combine the modified subtitle data with the video content data to create combined pattern data representing combined left-eye and combined right-eye display patterns.

Abstract: A data recording/playback configuration whereby data compatible with a standard such as the BD standard, AVCHD standard, or the like, and data incompatible with a standard are usable is realized. In the event that recorded data is data compatible with a standard such as the BD standard, AVCHD standard, or the like at the time of data recording processing as to a medium, the management information of the data is recorded in a first management information file only for data compatible with a standard, and in the event that the recorded data is data incompatible with a standard, the management information of the data is recorded in a second management information file. Also, management information updating processing for recording all of management information recorded in the first management information file in the second management information file is performed.

Abstract: A data recording/playback configuration whereby data compatible with a standard such as the BD standard, AVCHD standard, or the like, and data incompatible with a standard are usable together is realized. In the event that recorded data is data compatible with a standard such as the BD standard, AVCHD standard, or the like at the time of data recording processing as to a medium, the management information of the recorded data is recorded in a management information file only for data compatible with a standard, and in the event that the recorded data is data incompatible with a standard, a URI (Uniform Resource Identifier) that is file identification information to be applied to playback of recorded data is recorded in a file list. Playback processing is performed by using the management information file only for data compatible with a standard at the time of playback of data compatible with a standard, and by applying the file list at the time of playback of data incompatible with a standard.

Abstract: In processing of recording data on a recording medium, three-dimensional image discrimination data representing whether or not there is a possibility of a three-dimensional image being included in recorded data is recorded as management information. The three-dimensional image discrimination data is recorded in a clip information file set in association with a stream file as a storage file of image data, a playlist file including reproduction section designating information for the clip information file, a disc management file which directly or indirectly designates the playlist file, or the like. A reproducing apparatus can thereby easily determine the presence/absence of a three-dimensional image without performing analysis on reproduction target data.

The file conversion unit converts a file of the first file format generated by the application execution unit into a file of the second file format having an allowable size defined by the file system and supplies the converted file to the file system unit in the form of a file to be recorded.

Abstract: For a content-prerecorded large capacity disc-shaped recording medium, a user interface having high flexibility is accomplished. Button image data, corresponding sound data as an effect sound, and control commands for the sound data and image data are multiplexed with a stream and recorded on the disc. A scenario reproduced from the disc is stored in a buffer. The image data and sound data are stored in a buffer. Image data is read from the buffer in accordance with a scenario and expanded to a graphics plane. In addition, corresponding sound data is read from the buffer and reproduced by a sound player. When a button image is varied in accordance with a state change of the button, an effect sound is reproduced. As a result, a more effective user interface is accomplished.

Abstract: A data recording/playing configuration capable of easily acquiring attribute information on a frame constituting a 3D image recorded on a recording medium. The attribute information of the 3D image is recorded in each of hierarchized management information files as an attribute in units of management data of each of the management information files. When a coding method is a frame sequential method, frame identification data indicating whether each frame is a left-eye image (L image) or a right-eye image (R image) are recorded; and when the coding method is an inter-view reference coding method where any one of L and R images is referred to during decoding, base image identification data indicating which one of the L and R images is a base image are recorded. Thereby, a playing apparatus can determine an attribute of a frame without performing analysis of data to be played.
