In order to better understand the present invention, the following is directed to the working process of the multimedia playing control system provided by the embodiments of the present invention is briefly described.

Firstly, whether the control device 11 is connected with the first radio frequency module 13 is inquired, if the control device is connected with the first radio frequency module 13, the subsequent process is carried out, otherwise, relevant prompt information is sent out, and the inquiry is continuously executed until the control device 11 is connected with the first radio frequency module 13.

Then, the target identification code and the target operation instruction are input through the control device 11. More specifically, the target identification code and the target operation instruction are input, for example, by inputting text information or clicking a corresponding button through a graphic user interface in an application program.

Then, a target control command including the target identification code and the target operation instruction is generated by the control device 11.

Then, the target control command is converted into a radio frequency signal by the first radio frequency module 13 and transmitted. The radio frequency signal is generated, for example, by a series of amplification, modulation, and the like.

Then, at least one second rf module 15 is used to receive the rf signals, analyze the received rf signals to obtain the target control command, and send the target control command to at least one multimedia playing box 17.

Then, each multimedia playing box 17 determines whether the target identification code in the target control command is the same as its own identification code. And when the judgment result is the same, the multimedia playing box 17 executes the target operation instruction. That is, only when the object identification code is the same as the identification code of the multimedia player 17, the multimedia player 17 having the identification code identical to the object identification code executes the object operation command. If the working frequency band of the first rf module 13 is different from the working frequency band of the at least one second rf module 15, the working frequency band of the first rf module 13 needs to be adjusted to be equal to the working frequency band of the at least one second rf module 15. Because, only when the working frequency band of the working frequency band box of the first radio frequency module 13 is consistent with that of at least one second radio frequency module 15, the data sent by the other party can be correctly analyzed, and communication is realized.

The identification code of the multimedia play box 17 is set or preset by, for example, an application installed thereon.

Under some use scenes, such as a stage screen, the screens can be grouped to give different identification codes to the multimedia playing boxes connected with the screens of different groups, and the screens of the same group can be controlled at one time or the screens of multiple groups can be controlled at one time by controlling the multimedia playing boxes connected with the screens, so that the cool and dazzling stage effect can be realized.

The foregoing embodiment of the present invention replaces the network environment with the radio frequency module, thereby reducing the dependency on the network environment and improving the capability of the system concurrency control; only one radio frequency module is needed to be installed, equipment such as a router and a switch needed by a network environment is not needed to be established, and the degree of freedom of layout is high; the radio frequency module has long transmission distance and high speed, the remote control capability of the system is improved, and the working frequency band of the radio frequency module is different from that of a universal WIFI network, so that the interference can be reduced, and the stability of the system is improved; the USB interface radio frequency module can be conveniently connected with various computers with USB interfaces to be used as control equipment to construct a system; through the broadcast communication mode of the radio frequency module, the command can be synchronously sent to a plurality of multimedia playing boxes, and the identification code of the multimedia playing box is used for distinguishing whether the command needs to be executed or not, so that the synchronization of control is realized.
