Server coding method for online competition videos

Abstract

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.

[0002] 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 adding, a large amount of auxiliary information and other data are needed to ensure the effectiveness of data transmission. The current video encoding processing method It is still mainly aimed at the processing of a single video screen of an independent camera, and rarely involves the aforementioned combined video. The above problems lead to a very large amount of data in online event videos. During real-time transmission and playback, the cost requirements for equipment and users’ software and hardware are relatively high. High, and the efficiency of encoding and decoding is limited, which is not conducive to ensuring the timeliness and integrity of the event video, and it is easy to cause problems such as video freeze, or distortion and deformation, which brings bad experience to the viewers and increases the Operation and maintenance costs of broadcasting organizations
