Abstract: Method of managing input signals of a first display device includes determining a specified electronic device to be an input signal source of the first display device, and displaying a specified virtual remote controller of the specified electronic device on a second display device of a mobile device. In response to detecting touch signals on the second display device, a virtual remote controller is determined. When the determined virtual remote controller is different from the specified virtual remote controller, a first switch signal corresponding to the specified virtual remote controller is sent, and the input signal source is controlled to switch from the specified electronic device to a default electronic device. A second switch signal corresponding to the determined virtual remote controller is sent. The input signal source is controlled to switch from the default electronic device to an electronic device corresponding to the determined virtual remote controller.

Abstract: Method of remote control includes determining a selected virtual key on a user interface provided by the mobile device and acquiring an identification number of the selected virtual key from a storage device of the mobile device. In response to detecting infrared signals sent from a remote controller to an electronic device, the infrared module is controlled to record the infrared signals of one or more keys on the remote controller in sequence. The recorded infrared signals is stored to a queue corresponding to the identification number of the selected virtual key in sequence. Induction delay time corresponding to each of the recorded infrared signals in the queue are set.
