Background
During traditional events, performances and live broadcast, cameras with a plurality of machine positions are arranged on the site, and in traditional live broadcast, the switching of different machine positions is switched and controlled by a broadcast station. The director can switch the contents output by different machine positions and cut and combine the contents into one path to be transmitted to the online for the audience to watch. Thus, conventional viewers are completely passive, most of the content is carried by the director, and the viewers cannot choose to see what they want to see. This also results in a large number of points of interest to the viewer and a loss of highlights.
In traditional live broadcast, especially in event live broadcast, when a highlight picture appears, a director can form a 360-degree surround play effect of the frame picture by switching different contents output by the frame picture in a camera circling around one circle, and the frame picture is edited to highlight and played for a user. In addition, this play is also a still playback (or a playback of motion within a few frames) rather than a surround play during the entire live broadcast. In fact, the audience is interested in observing all angles of people and things which are interested in the audience, just like the people in the real world, and not only can stop watching in one plane.
As can be seen from the above, in the conventional live broadcasting, because the director controls the picture watched by the viewer, the degree of freedom of the picture content desired to be watched by the viewer is lacked, and the viewing angle and the subjective operability of the viewing angle at which the viewer watches the picture content are limited.

In this step, the video capture card is used to capture the video image.
S20: and splicing the video images of the plurality of visual angles and forming a video stream.
In this embodiment, the video images acquired by the plurality of cameras in the step S10 from a plurality of viewing angles are spliced to form a video stream for subsequent live broadcasting.
Specifically, in the present embodiment, the step S20 includes the following subdivision:
s21: stitching the video images of the multiple perspectives to form an integrated video package.
After the step of S10, the video images captured by the multiple cameras are synchronized on the same time axis, and thus, after the video images are spliced to form an integrated video package, each video image in the integrated video package is played on the same time axis.

When the display terminal is controlled to play the video images of other visual angles, the video images of one or more other visual angles can be played.
Specifically, in this step, after receiving the stream pushing instruction, the stream pushing server 23 pushes the video stream to the CDN with a preset address, for example, the preset address of the CDN is CDN 25.
The processed video stream will be pushed to CDN25 for download play. At this time, the display terminal used by the user pulls the video stream through the preset address of the CDN25, and downloads the video stream to the display terminal for playing.
In this step, a display terminal is controlled to play video images of one or more visual angles in the video stream;
the display terminal downloads a video stream (formed by splicing a plurality of video images), and selects one or more predetermined video images to play, namely, pictures shot by one or more cameras are played, and pictures shot by other cameras are not displayed on the display terminal at this time.
And responding to the received control instruction, and controlling the display terminal to play the video images of other visual angles.
The user can input a control instruction to control the display terminal to switch the video images to be played, for example, the user can drag the picture on the display terminal, and the step determines to switch to the required video images according to the dragging direction and the dragging distance. If the user drags to the left continuously, the display terminal receives the switching instruction continuously and switches to the next picture continuously, namely the picture of the camera which is continuously rightwards in reality, so that the whole visual angle turns to the right around the target area. Similarly, if the user continues to drag right, the switched video images are opposite.
Besides, the user can control the basic video playing function through the display terminal, and the control instruction can also include stopping playing or playing back.
