A video record system and an operation method thereof are provided. The video record system includes at least one camera and a controller connected with the at least one camera. The controller records a video around a vehicle using the at least one camera, records location information of the vehicle when recording the video, and provides a list of videos recorded according to a driving situation of the vehicle.

The present invention relates to a device and a method for transmitting and receiving a signal of a broadcast including a subtitle service. One embodiment of the present invention provides a broadcast signal transmitting method comprising the steps of generating a broadcast signal, which includes video data and subtitle data, and transmitting the generated broadcast signal. According to one embodiment of the present invention, a transmission stream for providing a digital broadcasting subtitle service using XML subtitles can be transmitted.

Systems and methods are disclosed for operating a surveillance system and managing beacon-augmented surveillance data. A surveillance system may include a camera, a controller, and a transceiver. The camera may be configured to generate image data. The controller may be configured to generate image metadata that indicates a surveillance system identifier, upload the image data and the image metadata to a server, and generate a beacon that indicates the surveillance system identifier. The transceiver may be configured to transmit the beacon.

A danger detection system is provided. The system includes a user computing device programmed to receive from a microphone of the computing device a signal indicating a gunshot-like sound and automatically determine if the gunshot-like sound is a gunshot. The user computing device is also programmed to automatically determine a location of the gunshot; and to automatically generate and send to a display of the user computing device a safety notification in response to determining if the gunshot is within a predetermined distance.

Techniques are described that allow DVR users to create program shortcuts to different types of media content from content providers. A program shortcut comprises a reference to another media content. A user may generate a shortcut so that the user may easily find and return to media content without performing a new search. In addition, techniques may be used to automatically generate program shortcuts for a user based at least in part to user-indicated preferences or actions. Shortcuts may be generated to media content that is related to a preferred genre or media type specified by a user. Shortcuts may also be generated to content that is determined to be similar to content that is often viewed or recorded by the user.

A vehicle system is disclosed. The system may comprise an imager, a location sensor, a controller, and a display. The imager may be operable to capture a first video having a plurality of frames with field of view exterior the vehicle. The location sensor may be operable to determine the vehicle's location. The controller may be operable to associate the location of the vehicle with a plurality of the plurality of frames where the location substantially corresponds to the vehicle's location when each respective frame was captured. Additionally, the controller may be further operable to store one or more video clips, each comprising a series of frames. The display may be operable to simultaneously show one of the video clips and a map of an area substantially encompassing all the locations of the vehicle associated with the first frames included in the shown video clip.

Various embodiments include devices, systems, and methods for managing storage of video in response to an event in a body-worn video recording device. A body-worn video recording device may continuously store images captured by the camera in the rolling buffer memory, and copy images stored on the rolling buffer memory and storing images captured by the camera in a non-volatile memory in response to determining that a trigger event has occurred. A network computing device may receive from a first body-worn video recording device a signal that a trigger event has occurred, select one or more second body-worn video recording devices in response to receiving the signal that the trigger event has occurred, and send activation messages to the selected one or more second body-worn video recording devices to store images from a respective rolling buffer memory and subsequently captured images in a non-volatile memory.

An information processing apparatus includes a content reproduction unit, a content part specification unit, a clustering unit, a class detection unit, a common class extraction unit, and a content retrieval unit. The content reproduction unit is configured to reproduce a reproduction content. The content part specification unit is configured to specify a plurality of content parts included in the reproduction content. The clustering unit is configured to classify the plurality of content parts into a plurality of clusters. The class detection unit is configured to detect a class from the plurality of content parts included in each of the plurality of clusters. The common class extraction unit is configured to extract a common class common to the plurality of clusters from the classes detected by the class detection unit. The content retrieval unit is configured to retrieve a content corresponding to the common class.

A wearable camera system includes a wearable camera, an in-car recorder, and an in-car camera. One of the in-car recorder and the wearable camera transmits video recording starting information including information indicating that video recording has been started to the other of the in-car recorder and the wearable camera when one of the in-car recorder and the wearable camera starts the video recording. The other of the in-car recorder and the wearable camera starts video recording after the video recording starting information is received.

A compensating timer system and method utilizable with video data featuring sections of different playback or recording speeds. The compensating timer system can be utilized with a user interface associated with and displayable thereon. The user interface can include a video display region configured or configurable to display video data, and an animated time indicator. The animated time indicator can be dependent on a modified playing speed of the video data that changes between different first and second speed rates. The first speed rate can be changed to the second speed rate upon receipt of an input associated with an affordance, by modifying at least one frame in the video data. This allows for continuous recording and/or displaying of video at different speed rates without altering operations or settings. The animated time indicator can be an animated affordance, an animated progress bar, an elapsed timer and/or a time remaining clock.
