The smart portable device such as a smart phone is equipped with powerful CPU, touch screen, USB socket, etc. The software application running on the smart portable device can convert the user commands received on the graphical user interface (GUI) into remote control codes and communicate the remote control codes as data packets through peripheral bus interface, such as USB, to a plug-in peripheral device. The plug-in peripheral device receives the data packets and drives the IR transmitter using information in the data packets received. The remote control codes in the form of modulated IR signals arrive at the electronic appliances such as TV, VCR, Hi-Fi systems, robots, etc. that can decode remote control codes.
