A playback method of reading out and playing streams from a recording medium is provided in which are recorded a stream file, a playlist file, first and second combination information, elementary streams that can be played at the same time with the first luminance video, and elementary streams that can be played at the same time with the second luminance video. The playback method includes in a case of playing the first luminance video, reading out any one of the elementary streams listed in the first combination information of the playlist file, and playing at the same time with the first luminance video, and in a case of playing the second luminance video, reading out any one of the elementary streams listed in the second combination information of the playlist file, and playing at the same time with the second luminance video.

Systems and methods can support a data processing apparatus. The data processing apparatus can include a data processor that is associated with a data capturing device on a stationary object and/or a movable object. The data processor can receive data in a data flow from one or more data sources, wherein the data flow is configured based on a time sequence. Then, the data processor can receive a control signal, which is associated with a first timestamp, wherein the first timestamp indicates a first time. Furthermore, the data processor can determine a first data segment by applying the first timestamp on the data flow, wherein the first data segment is associated with a time period in the time sequence that includes the first time.

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.

In various embodiments, a subtitle timing application detects timing errors between subtitles and shot changes. In operation, the subtitle timing application determines that a temporal edge associated with a subtitle does not satisfy a timing guideline based on a shot change. The shot change occurs within a sequence of frames of an audiovisual program. The subtitle timing application then determines a new temporal edge that satisfies the timing guideline relative to the shot change. Subsequently, the subtitle timing application causes a modification to a temporal location of the subtitle within the sequence of frames based on the new temporal edge. Advantageously, the modification to the subtitle improves a quality of a viewing experience for a viewer. Notably, by automatically detecting timing errors, the subtitle timing application facilitates proper and efficient re-scheduling of subtitles that are not optimally timed with shot changes.

A playback method of reading out and playing streams from a recording medium is provided. A stream file. including a first luminance video and a second luminance video, a playlist file, first and second combination information, elementary streams that can be played together with the first luminance video, and elementary streams that can be played together with the second luminance video are recorded in the recording medium. The playback method includes, when playing the first luminance video, reading out any one of the elementary streams listed in the first combination information of the playlist file, and playing at the same time with the first luminance video, and when playing the second luminance video, reading out any one of the elementary streams listed in the second combination information of the playlist file, and playing at the same time with the second luminance video.

Device for providing a playable sequence in renderable manner comprises: a providing unit for providing defined functions, said functions for applying playable effects to objects, a time unit for adding time boundaries to said functions, to provide time bounded functions, an ordering unit for ordering said time bounded functions into a sequence, and a translation unit for applying translations to said objects in accordance with said effects.

A recording medium includes a video stream of a standard-luminance range and a video stream of high-luminance range, which are used selectively in accordance with a playback environment. The recording medium also includes a subtitle stream of the standard-luminance range and a subtitle stream of the high-luminance range, which are used selectively in accordance with the playback environment. A playlist file includes a management region where playback control information relating to a main stream is stored, and includes an extended region. The management region stores first playback control information specifying playing of the video stream of the high-luminance range and the subtitle stream of the high-luminance range in combination. The extended region stores second playback control information specifying playing of the video stream of the standard-luminance range and the subtitle stream of the standard-luminance range in combination.

A playback device reads out from a recording medium and plays multiple High Dynamic Range (HDR) video streams that are encoded with video information. The playback device includes a first register, a second register and a playback unit. For each of the HDR video streams, the first register stores first information indicating whether the playback device corresponds to or not, and the second register stores second information indicating whether a display device connected to the playback device corresponds to or not. The playback unit plays the HDR video streams using a playback format selected based on a playback program stored in the recording medium, in a case where the first information and the second information indicate that there are multiple playback formats corresponding to both the playback device and the display device.

A method is provided for reading out contents of a video file having a predefined video file format. The contents include video frames of an object in motion captured by a video recording device, and motion data of an object collected by an inertial measurement unit (IMU) that is attached to the object. The motion data is stored as metadata in one or more time intervals of the video file. Parsing instructions are stored in a computer memory. The parsing instructions indicate how the metadata is parsed into motion data for one or more video frames that are associated with the respective motion data. The contents of the video file are read out using the stored parsing instructions, thereby identifying specific video frames with their respective correlated motion data.
