Method for displaying videos and control device

[0079] Please refer to figure 1 , is a flow chart of a method for displaying video provided in Embodiment 1 of the present application. The method is applied to a multi-screen display system, and the system includes a control terminal, M playback terminals connected to the control terminal, and The M groups of displays connected to the M playing ends respectively, M is a positive integer, and the method includes:

[0080] S101: The control terminal detects whether at least one first display for displaying at least one video in the M groups of displays is in a state of not being able to output video;

[0081] S102: If yes, the control terminal judges whether the N displays in the M groups of displays except the at least one first display have at least one display capable of displaying the at least one video in a state capable of outputting video The second display obtains the first judgment result, and N is a positive integer;

[0082] S103: When the first determination result i

[0122] Based on the same inventive concept as Embodiment 1 of this application, please refer to Figure 5 , is a structural block diagram of a control device for displaying video provided in Embodiment 2 of the present application, which is applied to a multi-screen display system, and the system includes the control device, M playback terminals connected to the control device, and The M groups of displays connected to the M playing ends respectively, M is a positive integer, and the control device includes:

[0123] A detection module 10, configured to detect whether at least one first display for displaying at least one video in the M groups of displays is in a state where video cannot be output;

[0124]The judging module 20 is used to determine whether the N displays in the M groups of displays except the at least one first display have a video output capable of displaying the at least one video when it is YES. At least one second display of the state, to obtain the first ju
