Abstract

The embodiment of the invention provides a video synthesis method and system. The method is applied to a guide station of the video synthesis system. The method comprises the following steps: receiving a video synthesis instruction, wherein the video synthesis instruction at least comprises a video main body and a video picture from different video sources; determining a first video source where the video main body is located and a second video source where the video picture is located; extracting target video data of the video main body in the first video source according to a preset algorithm; and superimposing the target video data to a preset location of the second video source. By adoption of the video synthesis method and system provided by the embodiment of the invention, on the basis of the existing live broadcast / recorded broadcast system, image matting and synthesis are realized through the guide station, the operation is convenient, and the original high-definition video data are retained; and for a live video source, the real-time output can be performed after the synthesis, thereby shortening the delay and meeting the live broadcast use demands.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of mobile communications, and in particular, to a video synthesis method and system. Background technique [0002] The video recording and broadcasting system integrates and records the video, audio, and image signals of electronic equipment (including computers, video booths, etc.) recorded on site to generate standardized streaming media files for external live broadcast, storage, post-editing, and on-demand broadcasting. . Viewers can log in to the server of the recording and broadcasting system to watch the live audio, video and graphic information, and can also order video information later. The video live broadcast system collects and encodes the above-mentioned image signals in real time into standard streaming data (such as FLV, WMV format) for management, classification, etc., and transmits them to the server and publishes them in the form of pages for the audience to watch li...
