Abstract: An auto switch system and method thereof for IP phones and default audio devices. The system may automatically switch voice output of an information apparatus between the IP phone and the audio device according to IP phone usage. Thus, inconvenience caused by the IP phone being set as the default output is overcome. Furthermore, users need not change the settings when using IP phones.

Abstract: A remote control apparatus with an acknowledge requesting signal button is provided, which sends an acknowledge requesting signal to a target appliance when pressed. The control circuit of a target appliance includes a device identification information storage unit for storing a pre-determined device identification of the appliance. Upon receiving an acknowledge requesting signal from the remote control apparatus, the target appliance responds with information including the device identification, the corresponding communication protocol of the appliance, and control button mapping. When the remote control apparatus receives the response from the target appliance, the display unit of the remote control apparatus displays the corresponding control button mapping (or layout) and configures the communication protocol for controlling the target appliance remotely. The apparatus also stores a plurality of device identifications so that a single apparatus is able to control a plurality of electrical appliances.

Abstract: An apparatus and method for controlling multi-master devices with pseudo IR signals is used by setting one of the master devices as a master module and others as pseudo slave module, the master module receiving and decoding the IR signals, and then confirming the IR signals are used to control which device. If the signals decoded from the IR signal are used to control the master module, the apparatus uses the signal to control the master module. Otherwise, if the signals decoded from the IR signal are used to control the pseudo slave module, the apparatus generates a pseudo IR signal and sends the pseudo IR signal to pseudo slave module, to control the manipulation of the pseudo slave module.
