Abstract

An electronic device connected to numerous first load medias and second load medias. The electronic device comprises a processor and a switch module. The processor is capable of switching between a first working mode and a second working mode. Under the second working mode, the processor generates a second control signal, the switch mode establishes independent electronic connections between specified first load medias and specified second load medias, thus, the first load medias and the second load medias simultaneously communicate with each other through the electronic device.
