A method that applies supplementary attribute information to the e-book content is provided. The method includes retrieving the e-book content; identifying objects in the retrieved e-book content; selecting one or more of the objects; defining one or more screen alteration attribute values regarding the selected objects; collecting an application condition for applying the defined screen alteration attribute values to the selected objects; and generating the supplementary attribute information by binding the defined screen alteration attribute values to the selected objects, and an action condition.

A playlist file for controlling playback of a VOB stream file is recorded in a recording medium. A CombiExt_for_Cell( ) and Combi( ) indicating combinations of elementary streams that each can be played at the same time in the same Cell are described in the playlist file. Elementary streams that can be played at the same time as SDR video are listed in the CombiExt_for_Cell( ), and elementary streams that can be played at the same time as HDR video are listed in Combi( ). The number of elementary streams of a predetermined type listed in CombiExt_for_Cell( ) and the number of elementary streams of the predetermined type listed in Combi( ) are each equal in the same Cell.

Systems, methods, and articles of manufacture to manage tracks and/or other multimedia items are disclosed. An example method includes displaying on an interface of a computing device, a plurality of tracks in a sequential order. The example method receiving, via the interface, an input to play a particular track from the plurality of tracks, wherein the particular track is at a particular position in the sequential order. The example method displaying on the interface, a queue comprising at least a subset of the plurality of tracks to be played after playback of the particular track, wherein each track in the subset of the plurality of tracks is at a different position in the sequential order than the particular position of the particular track.

To acquire attribute information of high dynamic range (HDR) data from a playlist file and a clip information file to realize video reproduction according to a display device. A data processing unit that executes reproduction processing of disk recorded data acquires the playlist file and the clip information file as reproduction control information files corresponding to reproduction data recorded on a disk, determines whether HDR graphics data is recorded on the disk on the basis of record data of these files, and further acquires attribute information of the HDR graphics data from reproduction control information, and executes control of output data for the display device according to the acquired information in a case where the HDR graphics data is recorded on the disk.

The present technology relates to a reproducing apparatus for enabling an appropriate video depending on a viewing environment to be reproduced, a reproducing method, an information processing apparatus, an information processing method, a program, and a recording medium. The reproducing apparatus according to the present technology analyzes reproduction management information describing therein type information on a form of providing a HDR video which is compatible with a SDR video with a standard luminance range and whose luminance range is wider than the standard luminance range or a form of providing the SDR video compatible with the HDR video. Further, the reproducing apparatus acquires and reproduces encoding data of the HDR video or encoding data of the SDR video provided in a form indicated by the type information. The present technology is applicable to Blu-ray Disc players.

A playback device plays video streams recorded in a recording medium, in which are one or more video streams including at least one of an HDR stream whose dynamic range of luminance of video corresponds to a high dynamic range (HDR), and an SDR stream whose dynamic range of luminance of video corresponds to a standard dynamic range (SDR) narrower than HDR, and identification information indicating whether the HDR stream is included in the one or more video streams. A playback method of the playback device includes: reading the identification information from the recording medium; acquiring playback capability information indicating whether the playback device can play the HDR stream, and display capability information indicating whether a connected display device can display the HDR video; and deciding on a video stream from the one or more video streams, according to the identification information, the playback capability information, and the display capability information.

Systems and methods for managing data with respect to tape storage are provided. The system includes a data manager for receiving metadata related to content and for generating a proxy file system which mirrors the data structure of the content data. The system further includes a server coupled to a tape device, the server receiving the content data directly from a data source and providing the content data the tape device for storage on a formatted tape media.

The present technology relates to a reproduction device, a reproduction method, and a recording medium that enable content having a wide dynamic range of brightness to be displayed with an appropriate brightness. A recording medium, on which the reproduction device of one aspect of the present technology performs reproduction, records coded data of an extended video that is a video having a second brightness range that is wider than a first brightness range, brightness characteristic information that represents a brightness characteristic of the extended video, and brightness conversion definition information used when performing a brightness conversion of the extended video to a standard video that is a video having the first brightness range. The reproduction device decodes the coded data and converts the extended video obtained by decoding the coded data to the standard video on the basis of the brightness conversion definition information.

A method according to one aspect of the present disclosure includes the steps of: acquiring a play list including identification information indicating each of a plurality of elementary streams; selecting an elementary stream indicated by predetermined identification information from the acquired play list; acquiring a difference file including data that is not included in the selected elementary stream; and converting the selected elementary stream into an MP4 file format by combining data included in the difference file and data included in the selected elementary stream based on a manifest file corresponding to the selected elementary stream, the manifest file being necessary for the conversion of a file format based on a predetermined rule.

An audio processing apparatus includes an audio file recovery unit configured to recover an audio file related to a video file. With video data of the video file and audio data of the audio file recorded at different speed rates from each other, the audio file recovery unit recovers the audio file so that an end position of the audio data coincides with an end position of the video data in playback of the audio data and the video data at a speed rate.
