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.

Computer implemented techniques that involve captured, e.g., self-captured video for educational and other uses such as improving job performance of geographically distributed employees and incremental video optimizations and compressions are described.

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 system for combining data includes one or more processors that are, individually or collectively, configured to receive video data recorded by at least one sensor and operation data of a movable object that carries the at least one sensor, associate the operation data with the video data, and store the associated operation data and the video data in a video file. The operation data indicates one or more operation states of the movable object during a time period when the video data is recorded.

A method of processing a video includes capturing a first set of video data at a first definition, transmitting the first set of video data at a second definition lower than the first definition wirelessly to a user terminal, receiving a video edit request wirelessly from the user terminal, and finding video corresponding to edited video data described by the video edit request, thereby forming a second set of video data at a third definition. The video edit request is formed from editing the received first set of video data at the second definition at the user terminal.

A video recording system is disclosed and claimed. In particular, the disclosed video recording system maintains a master stream of video and audio when recording is initiated, but also allows the user to create additional label streams by activating an input control. The label stream can be terminated by activating input control a second time. The label stream comprises only the portion of the video and audio between the activations of the input control, while the master stream will contain all audio and video that is recorded on the device. The video stream can be associated with an event, and labeled with an event name by activation of an event control. The event-labeled video stream is stored and organized in a remote data storage unit by activation of a remote storage control. The event-labeled video streams and the label streams are accessible by multiple video recording systems through a network.

An image capturing control apparatus that enables a user to recognize a transparency of OSD for recording. A system controller sets a transparency of OSD superimposed on a captured LV image and sets whether or not to record the captured image in a state combined with the OSD, as an image file. The OSD is displayed in a state superimposed on the LV image at a transparency of OSD for display, regardless of a setting concerning recording of the image file, and in a case where it is set to record the LV image in the state combined with the OSD, the OSD is displayed according to a specific operation, in a state superimposed on the LV image, at a transparency of OSD for recording, regardless of the transparency of OSD for display.

Real-time metadata tracks recorded to media streams allow search and analysis operations in a variety of contexts. Search queries can be performed using information in real-time metadata tracks such as closed captioning, sub-title, statistical tracks, miscellaneous data tracks. Media streams can also be augmented with additional tracks. The metadata tracks not only allow efficient searching and indexing, but also allow insertion of content specific advertising during appropriate portions of a media stream based on the content of the metadata tracks.
