Superposition method and superposition system of video structured information, and user terminal

Abstract

The invention provides a superposition method and a superposition system of video structured information, and a user terminal. The method comprises the following steps: the user terminal receives at least one video frame, wherein the video frame is synchronously sent by a video source server to the user terminal and an algorithm server; meanwhile, the user terminal further receives structured information sent by the algorithm server, wherein the structured information is generated by the algorithm server by identification of a monitoring target in the video frame and in accordance with the monitoring target; and finally, the user terminal superposes custom information in the video frame according to a timestamp of the video frame, a video timestamp in the structured information and a position coordinate of the custom information. In the superposition method provided by the embodiment of the invention, the algorithm server is only used for generating the structured information without superposing the structured information, the superposition process of the structured information is executed by the user terminal, so that the superposition speed of the structured information is accelerated, thereby both guaranteeing the display instantaneity of video stream and reducing the requirements of the superposition system for the software and hardware configuration.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a method for superimposing video structured information, a user terminal and a superimposing system. Background technique [0002] At present, with the rapid development of video processing technology, video superimposition technology can meet the different needs of different users for custom information in video, superimpose some custom information to the specified position in a specific video frame in the video, and then superimpose A video with custom information is presented to the user. For example, a user terminal applies for subscribing to a certain topic information. At this time, the topic information needs to be superimposed on the video, and then the video superimposed with the topic information is sent to the corresponding user terminal. [0003] At present, a method for superimposing video structured information is provided in related technologies. T...

Problems solved by technology

That is, it is necessary to add a streaming media server, thus increasing the system hardware and software configuration cost; in addition, when the algorithm server processes real-time video, it not only needs to generate structured information to be superimposed, but also needs to superimpose the structured information to be superimposed For video, a lot of calculations are required and the processing efficiency needs to be real-time. At least the processing speed must be guaranteed to be the same as the frame rate of the video. Dedicated servers to do these tasks in parallel

[0004] In the process of realizing the present invention, the inventors found at least the following problems in the related technologies: the video information overlay technology in the related technologies needs to generate structured information related to the video stream by an algorithm server, and simultaneously superimpose the structured information on the video At the specific position of the corresponding video frame of the stream, due to the large amount of data processed by the algorithm server and the need to ensure the real-time performance of the video display during the real-time video processing process, it is necessary to ensure the video information superimposition speed, and then the configuration requirements of the video information superposition system high
