During the event broadcasting process, due to the rapid changes in the field conditions, the large number of athletes, and the focus content of the audience is not completely consistent. Therefore, in the process of recording and transmitting the event video, multiple sets of equipment are often required to cooperate with each other. In the emerging long-term In screen video and other technologies, the video data of multiple devices can be combined and synthesized to form a video with a wider viewing angle and a clearer picture, and obtain a viewing experience similar to panoramic video, which will improve the viewing experience in the future and ensure the integrity of event information. An important technical means of timely transmission, but the response of this technology is accompanied by a large amount of video data. In the process of encoding and addin

Embodiment Construction
[0036] The present application will be described in detail below in conjunction with specific embodiments.
[0037] An online event video server encoding method of the present application is mainly used in the encoding process of online event video, used to reduce the data volume of event video, and at the same time improve the clarity and efficiency of multi-video combined utilization. Its basic content includes:
[0038] 1. Set up a multi-channel video acquisition device and corresponding hardware and software, establish the hardware foundation for transmitting the event video to the server, and obtain multiple original video data;
[0039] In order to ensure the smooth progress of video combination and reorganization in subsequent steps, in this application, the multi-channel video acquisition device requires at least two cameras, and the cameras used for video combination need to have at least 25% of the acquisition area overlap;
[0040] 2. Based on the video combination ...

The invention belongs to the technical field of online competition video transmission, and particularly relates to a server coding method for online match videos. The method comprises the following steps: setting a multi-channel video acquisition device, and obtaining multi-channel original video data; obtaining a recombined video based on the video combination; establishing a key point set of two paths of video frames acquired at the same time node; calculating and combining projection frames corresponding to the two paths of video frames; combining the video frames and the projection frames S' to obtain a combined frame; and determining a key frame and related parameters to complete video coding. According to the server coding method for online competition videos, the data volume after video coding can be effectively compressed, the network transmission pressure of the online competition video is reduced, the rebroadcasting cost is further controlled, meanwhile, the method can well adapt to a future video combination utilization mode, the compatibility is good, and smooth transition between an existing traditional transmission scheme and a future multi-video combined transmission mode is facilitated.
