The display terminal 30 is further configured to play the primary selection video data sent by the server.

When it needs to be explained, the playback operation sent by the user may also include the operation of inputting the selected time information. The server determines whether the corresponding primary selection video data is stored according to the selected time information. If the primary selection video data is not stored, a prompt is obtained. information to remind the user through the display terminal whether to obtain the selected video data from the selected video capture terminal (the selected video data is usually the video data captured in real time), when the user sends a confirm operation, it means that the user is willing to The acquisition terminal acquires the corresponding selected video data, that is, based on the determination operation, an acquisition instruction is acquired, and the server acquires the selected video data from the selected video acquisition terminal based on the acquisition instruction. When the server stores the primary selection video data corresponding to the selected time information, the display terminal can directly play it. At the same time, the display terminal can also store the primary selection video data, so as to play the primary selection video data multiple times.

In addition, before obtaining the prompt information, when storing the preliminary selection video data corresponding to the selected time information, the server may search for the preliminary selection video data corresponding to the selected time information at the corresponding selected video collection terminal, When the primary selection video data corresponding to the selected time information is found, the server directly acquires the primary selection video data corresponding to the selected time information, and sends it to the display terminal, and the display terminal plays the primary selection video data ; When the corresponding selected video collection terminal does not find the primary selection video data corresponding to the selected time information, continue to perform the step of obtaining prompt information.
