Abstract: A signal expansion selection device receives a plurality of selection data from users to select one of audio-video signals generated from audio-video apparatuses. Each of the audio-video signals selected by a corresponding one of the users is converted into an audio-video datum for use by the user. The signal expansion selection device includes selection ports, a processing unit, multiplexing modules, and audio-video output ports. The selection ports send the selection data to the processing unit. The processing unit processes the selection data with an algorithm to generate a control command. The multiplexing modules select one of the audio-video signals according to the control command. The processing unit decodes and converts the selected audio-video signal to audio-video data and enables the audio-video data to be sent from one of the audio-video output ports.
