Abstract: An extended functionality remote control (EFRC) provides a hardware/software implementation of an integrated interface for remote control emulation. A PDA or other portable computing device is used as a platform for the EFRC application software and peripheral hardware. The EFRC also merges information services into remote controls. Implementation of these information services takes the form of, e.g., electronic program guides (EPGs) merged with the functioning of remote controls. In addition to the portable computing device, the hardware portion of the invention according to a preferred embodiment includes a keypad and an infrared transmitter subsystem which are managed by a microcontroller. The microcontroller also exchanges data with application software of the computing device via a serial communications link.
