Control method of display system, video synchronous playing method and display system

The invention relates to the technical field of display control, particularly provides a control method of a display system, a video synchronous playing method and the display system, and aims to solve the problem of how to realize low cost, high efficiency and flexible configuration of a video synchronous splicing playing process. In order to achieve the purpose, one tiled display terminal receives the synchronous control instruction and then sends the synchronous control instruction to other tiled display terminals, and synchronous control over the multiple tiled display terminals is achieved. Meanwhile, an independent control mode can be realized according to the equipment identification of the tiled display terminal which needs to be independently controlled, and the tiled display terminal which receives the equipment identification sends the equipment identification to other tiled display terminals, so that the equipment identification is locally stored by the plurality of tiled display terminals; therefore, the tiled display terminal corresponding to the equipment identifier is independently controlled, other tiled display terminals are synchronously controlled, and more flexible, efficient and low-cost synchronous control and synchronous playing can be realized.
