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.

Generation and use of user-selected scenes playlist from distributed digital content

A digital content package includes first content comprising a video feature such as a motion picture or the like, and a user-selectable application configured to operate as follows. When activated using an icon off of a menu screen, the application records an identifier for scenes (discrete portions) of the first content that are selected by a user to generate a playlist. The user may select the scenes by indicating a start and end of each scene. The application saves the playlist locally, then uploads to a server. Via a user account at the server, a user may publish the playlist to a user-created distribution list, webpage, or other electronic publication, and modify the playlist by deleting or reordering scenes.

System and method for presenting content with time based metadata

Systems and methods are described for presenting content with time-based metadata. Methods may comprise transmitting the time-based metadata to a playback device. The time-based metadata may comprise a plurality of time stamps that are triggerable at different points of a timeline of content and one or more of the time stamps may be associated with corresponding metadata content. The playback device may trigger a sequence of time stamps of the time-based metadata and the triggered sequence of time stamps may be synchronized with the occurrence of one or more events in the timeline of the content.

PLAYBACK DEVICE, PLAYBACK METHOD, AND RECORDING MEDIUM

A non-transitory recording medium is provided that is reproduced by a playback device having an attribute reader, a decoder, and an outputter. The recording medium has recorded therein a video stream that is encoded video information, and a management information file correlated with the video stream. The management information file includes first attribute information, indicating whether a dynamic range of luminance of the video stream is a first dynamic range or a second dynamic range that is wider than the first dynamic range. In a case where the first attribute information indicates the second dynamic range, the first attribute information also indicates a type of the second dynamic range.

Recording medium, reproducing apparatus, and reproducing method

In a recording medium on which is recorded a multiplexed stream including a plurality of first packets (V_main) constituting a first I-picture in a first video stream and a plurality of second packets (V_sub) constituting a second I-picture in a second video stream, information for identifying the first I-picture and information for identifying the second I-picture are recorded on the medium. A recording medium can thereby be obtained that enables the rapid detection, from a small amount of information, of a particular picture included in a stream such as a TS in which multiple content streams are multiplexed.

Recording medium, playback method, and playback device

Recorded in a recording medium is a video stream, map information, and bitrate information of the video stream. The map information includes size information indicating data size of a section where a picture is recorded in the video stream, based on a predetermined stipulated data size. The stipulated data size differs in accordance with the bitrate information.

Playback device, playback method, and recording medium

A playback device includes: an attribute reader that reads out first attribute information, indicating whether a dynamic range of luminance of the video stream is a first dynamic range or a second dynamic range, from a management information file recorded in the recording medium in a manner correlated with the video stream; a decoder that generates decoded video information by reading the video stream out from the recording medium and decoding the video stream; and an outputter that, in a case where the first attribute information that has been read out indicates the second dynamic range, outputs the decoded video information, along with maximum luminance information indicating a maximum luminance of the video stream in accordance with the second dynamic range.

INFORMATION RECORDING APPARATUS AND DATA ERASURE METHOD
20190066726 · 2019-02-28 ·

An information recording apparatus includes: a first memory which stores synchronization data for updating data on a recordable optical disc and/or adding data to the recordable optical disc; a second memory which stores erasure information indicating data to be erased; and a controller which controls addition, update, and erasure of data on the optical disc. The controller records the synchronization data onto the optical disc. After recording the synchronization data, the controller records, onto the optical disc, management information indicating the state of the optical disc on which the synchronization data has been recorded and the state of the optical disc resulting from erasure according to the erasure information. Subsequently, the controller closes the session. After closing the session, the controller physically erases the data to be erased which has been recorded on the optical disc.

Computer implemented method for use in a play back apparatus

A computer-implemented method is provided that includes determining whether a display apparatus that displays video played back by a playback apparatus supports an optional feature for playback of the video by using a first technique. The method also includes determining whether the display apparatus supports the optional feature for playback of the video by using a second technique that differs from the first technique in case that it is indeterminate whether the display apparatus supports the optional feature by using the first technique.

Recording and reproducing data based on conversion of data format
