A data processing method and device for a Light emitting diode (LED) Television (TV), and an LED TV are disclosed, the data processing device includes: a signal processing chip configured to perform mode conversion on a received TV signal so as to obtain a first video signal of a preset mode; and a video processing chip connected to the signal processing chip and configured to perform clock synchronization processing on the first video signal so as to obtain a second video signal and output the second video signal to an LED display. The problem in the prior art that an LED TV can only display a TV signal of a single mode is solved, thereby achieving the effect that the LED TV can display videos of various modes and various formats.

Methods and systems are provided for video processing. Video may be captured using an image capture device at a first definition. The image capture device may optionally be, or may be on board, an aerial vehicle, such as an unmanned aerial vehicle. A first set of video data may be transmitted to a user terminal at a second definition, which may be less than the first definition. A user may interact with the user terminal to edit the video and generate a video edit request. The video edit request may be transmitted to the image capture device, which may accordingly produce a second set of video data in accordance with the video edit request, at a third definition. The third definition may be greater than the second definition.

An image information management system includes: a storage medium on which peculiar information is stored; a reading device which reads the peculiar information stored on the storage medium; an image imaging device which shoots a video of a vicinity of a place at which the reading device is provided when the peculiar information stored on the storage medium is read by the reading device; and a processing device which associates, with the peculiar information, image information shot with using the imaging device in a constant time including a time point at which the reading device reads the peculiar information, and registers them in a storage unit. The image information management system reads the peculiar information stored on the storage medium, and associates the peculiar information with the picture information to store them in the storage unit. Then, based on the peculiar information, the image information management system chooses the picture information associated with the peculiar information and stored on the storage unit, and displays it on a display.

Systems and methods for routing audio for audio-video recordings allow a user to record desired audio with captured video at the time the video is being captured. Audio from one or more sources may be routed to the video capture application and recorded with the video. In one or more examples, audio may be routed from another application, e.g., an audio playback application, running on the same device as the video capture application. In another example, audio may be received from a remote device through a wireless connection. Multiple streams of audio content may be mixed together prior to storing with video. The audio, upon reception, may then be routed to the video capture application for recordation. An audio progression bar may also be provided to indicate duration and elapsed time information associated with the audio being recorded.

A playback method according to one aspect of the present disclosure is performed by a playback device connected to a display device. The playback method includes obtaining a type of the display device; selecting each of a version of High-Definition Multimedia Interface (HDMI) and a version of High-bandwidth Digital Content Protection (HDCP), according to the obtained type of the display device; obtaining a video signal of content recorded on a recording medium; decoding the obtained video signal; encrypting the decoded video signal using the selected version of HDCP; and outputting the encrypted video signal to the display device using the selected version of HDMI.

Embodiments of the invention include a subtitling format encompassing elements of enhanced syntax and semantic to provide improved animation capabilities. The disclosed elements improve subtitle performance without stressing the available subtitle bitrate. This will become essential for authoring content of high-end HDTV subtitles in pre-recorded format, which can be broadcast or stored on high capacity optical media, e.g. the Blue-ray Disc. Embodiments of the invention include abilities for improved authoring possibilities for the content production to animate subtitles. For subtitles that are separate from AV material, a method includes using one or more superimposed subtitle layers, and displaying only a selected part of the transferred subtitles at a time. Further, colors of a selected part of the displayed subtitles may be modified, e.g. highlighted.

For video searching, a set of objects and a relationship between objects in the set of objects is determined in a portion of a script for creating a video. From a collection of video clips, a set of video clips is selected based on matching an object from the set of objects to an object specified in a metadata of a video clip that is selected in the set of video clips. A duration of the relationship in the portion is computed. video analysis is performed on the video clip to determine whether the video clip includes the relationship. When the video clip includes the relationship, a determination is made whether the relationship in the video clip is at least of the duration. When the relationship is at least of the duration, the video clip is selected as a fit for the portion of the script.
