REMOTE CONTROL SIGNAL-USING DEVICE, REMOTE CONTROL SIGNAL-USING METHOD, CAR NAVIGATION APPARATUS, AND DISPLAY APPARATUS

摘要

The present invention utilizes a remote control signal for transmitting commands respectively from a remote controller and a touch panel. A signal generator generates a second remote control signal from a two-dimensional coordinate value signal (touch panel output). The second remote control signal does not overlap a first remote control signal (remote controller output). The remote control signal includes first one-byte data and second one-byte data. The first remote control signal exists on first portion that is defined as a group of points. These points exist on a diagonal of two-dimensional coordinate. The second remote control signal is transmitted via a cable. Processor performs remote control processing upon being the first remote control signal and performs a touch panel processing upon being the second remote control signal.
