The present disclosure describes techniques of synchronizing subtitles in live broadcast The disclosed techniques comprise obtaining a source signal and a simultaneous interpretation signal in a live broadcast; performing voice recognition on the simultaneous interpretation signal in real-time to obtain corresponding translation text; delaying the simultaneous interpretation signal to obtain a first delayed signal; delaying the source signal to obtain a second delayed signal; obtaining proofreading results of the first delayed signal and the corresponding translation text; determining proofread subtitles based on the proofreading results; and sending the proofread subtitles and the second delay signal to a live display interface.

In some embodiments, a method receives a message that identifies an asset being viewed on a video service at a timestamp. The message is associated with a profile identifier and a plurality of messages are received for the profile identifier while using the video service. The method determines a channel identifier for a channel in which the asset is offered during the timestamp and determines whether a channel change occurred based on the channel identifier and a prior channel identifier determined from a prior message in the plurality of messages. When the channel change has occurred, the method stores the channel identifier and timestamp for the profile identifier in a data structure, wherein a list of channels is generated by querying the data structure to determine a set of channel identifiers and timestamps for the profile identifier.

The present application discloses an intelligent processing method and system for video data, wherein, in the method an intelligent camera set a warning rule, the method comprises: the intelligent camera collecting video data and analyzing the collected video data in real time, generating intelligent data if the warning rule is met, which intelligent data contain an encoder identifier and motion trajectory information; the intelligent camera packaging the video data and the intelligent data into a program stream and sending it to a frame analyzing component in a cloud storage system; the frame analyzing component unpacking the received program stream to obtain the video data and the intelligent data, and storing the video data and the intelligent data in storage components respectively; the storage components sending storage address information of the video data and the intelligent data to an index server for recording respectively. The solutions of the present application can perform intelligent processing for the collected video data in real time.

A method for receiving a real-time video feed of a region of interest includes generating, at a processor of a first device, a request for a real-time video stream of the region of interest. The request indicates a location of the region of interest. The method also includes transmitting the request to one or more other devices via a network to query whether another device is situated to capture a portion of the region of interest. The method also includes receiving the real-time video stream of the region of interest from a second device of the one or more other devices. The second device includes a camera having a field of view that includes at least a portion of the region of interest.
