It should be noted that, in the embodiment of the present invention, the step S4 may be performed before the step S3, may be performed simultaneously with the step S3, or may be performed after the step S3. If step S4 is performed after step S3, step S4 may be performed simultaneously with step S5, which is not limited in the embodiment of the present invention.
And S6, the matrix switcher receives the mapping instruction, and when the target playing device plays the specified resource according to the playing instruction, the matrix switcher executes mapping operation according to the mapping instruction so as to display the specified resource on the specified display device.
