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.

To enable an HDR image and an HDR image metadata to be stored in an MP4 file, and a reproduction device to reproduce an optimum HDR image based on metadata. In generating the MP4 file that stores HDR image data, the HDR image metadata is recorded in the MP4 file. An HDR image metadata storage box is set to a trak box or a traf box in the MP4 file, and the HDR image metadata is stored. The reproduction device acquires the HDR image metadata stored in the MP4 file, determines whether executing a conversion process of the HDR image read from the MP4 file according to the acquired metadata and display function information of the display unit, and executes an output image generation process according to a determination result.

A vehicle camera and record system including a plurality of cameras located around a vehicle. The cameras are positioned such that at least a 360-degree planar view is provide surrounding the vehicle. A control unit is operably coupled to the cameras. The controller includes a computer readable storage device. The cameras will record the surrounding area of the vehicle. Media recorded by the cameras will be stored on the computer readable storage device such that the media can be accessed at a later time and date.

A play back device includes a readout unit and a playback unit. The readout unit reads out an encoded main video stream and an encoded sub-video stream that are recorded in a recording medium. The sub-video stream is a sub-video that is to be superimposed on the main video and displayed. The playback unit plays the main video stream and the sub-video stream that have been read out. The sub-video stream includes multiple sets, each set including a first sub-video stream for a first luminance dynamic range and a second sub-video stream for a second luminance dynamic range, which is wider than the first luminance dynamic range. In the same set in the multiple sets, a registration order of the first sub-video stream in the first database and a registration order of the second sub-video stream in the second database are the same.

A method, system and computer program product for interactively identifying same individuals or objects present in video recordings is disclosed. When a thumbnail in a set of thumbnails is selected, new information is obtained. The new information may be that an individual or object is present in the portion of the video recording associated with the thumbnail. A search can be carried out for the individual or object based on the new information. The search generates new match likelihoods for each of displayed thumbnails within a user interface page. The displayed thumbnails are re-ordered based on the new match likelihoods.

A data recording apparatus including: a data reading device configured to read data from a first recording medium and configured to store data and first management data for managing the data by file; a data recording device configured to record data on a second recording medium; a management data producing device configured to produce second management data for managing data recorded on the second recording medium based on the first management data of the first recording medium on which the data recorded on the second recording medium has been recorded; a data determining device configured to determine data unrecorded on the second recording medium by comparing the first management data read by the data reading device from the first recording medium with the second management data recorded on the second recording medium; a control device configured to read the data determined by the data determining device from the first recording medium and cause the recording device to record the read data onto the second recording medium; and a display device configured to display the recording status of data, managed by the first management data read by the reading device from the first recording medium, on the second recording medium, wherein the recording status includes one of recording of data complete, recording of data in progress, and recording of data yet to begin.

The techniques described herein relate to methods, apparatus, and computer readable media configured to access multimedia data that has a hierarchical track structure that includes at least a first track at a first level of the hierarchical track structure comprising first media data, wherein the first media data comprises a first sequence of temporally-related media units, and a second track at a second level in the hierarchical track structure that is different than the first level of the first track, the second track comprising metadata specifying a temporal track derivation operation. The temporal track derivation operation is performed on a set of media units comprising at least the first sequence of temporally-related media units to temporally modify the set of media units to generate second media data for the second track, wherein the second media data comprises a second sequence of temporally-related media units from the set of media units.

A system presents a media playback. The system receives a plurality of time stamped trigger data. The system reads a plurality of media segments from a media capture device. Each media segment corresponds to a respective time stamped trigger datum. The system outputs the plurality of media segments as a playback including the plurality of media segments.

The present technology relates to a playing apparatus, a playing method, an information processing apparatus, an information processing method, a program, and a recording medium that allow playing of appropriate HDR videos. A playing apparatus in an aspect of the present technology has a storage unit that has regions for storing a plurality of units of information indicating the state of the playing apparatus including preference information indicating the type of an HDR video to be preferentially played, out of a first HDR video that is essential in including in a content an HDR video as a video in a wider brightness range than a standard brightness range and a second HDR video that is capable of being included in the content. The playing apparatus acquires encoded data of the HDR video to be preferentially played indicated by the preference information, out of encoded data of the first HDR video and encoded data of the second HDR video, and decodes the acquired encoded data. The present technology is applicable to Blu-ray disc players.
