Similarly, when the linkage group display adjustment instruction is sent, some sending cards cannot receive the linkage group display adjustment instruction due to factors such as a network state, so that a repeated sending mechanism is also set for the linkage group display adjustment instruction in the embodiment of the application. Meanwhile, in order to prevent the transmitting card from repeatedly executing the same linkage group display adjustment instruction, to improve the efficiency of the packet control, steps S206 to S207 are further executed after step S203, and referring to fig. 6, steps S206 to S207 are specifically as follows:
