Remote control signal-using device, remote control signal-using method, car navigation apparatus, and display apparatus

A car navigation apparatus comprising:

• a display panel;
• a touch panel being placed on the display panel, the touch panel outputting a two-dimensional coordinate value signal in response to a touch;
• a receiver receiving a first remote control signal from a remote controller;
• a signal generator generating a second remote control signal from the two-dimensional coordinate value signal, the second remote control signal not overlapping the first remote control signal;
• a code analyzer analyzing a remote control signal originating from the receiver or the signal generator to determine if the remote control signal is the first remote control signal or the second remote control signal;
• a remote control processor performing remote control processing depending on the remote control signal, upon the remote control signal being the first remote control signal;
• and
• a touch panel operation processor performing a touch panel processing depending on the remote control signal, upon the remote control signal being the second remote control signal,
• wherein:
• the remote control signal includes first one-byte data and second one-byte data;
• the first remote control signal exists on a first portion which is defined as a group of points existing on a diagonal of a two-dimensional coordinate consisting of the first one-byte data and the second one-byte data;
• and
• the diagonal has a first endpoint consisting of a minimum value of the first one-byte data and a maximum value of the second one-byte data, and has a second endpoint consisting of a maximum value of the first one-byte data and a minimum value of the second one-byte data.

A display apparatus, comprising:

• a display panel;
• a touch panel placed on the display panel, the touch panel outputting a two-dimensional coordinate value signal in response to a touch;
• and
• a signal generator generating a second remote control signal from the two-dimensional coordinate value signal, the second remote control signal not overlapping a first remote control signal,
• wherein:
• the remote control signal includes first one-byte data and second one-byte data;
• the first remote control signal exists on a first portion which is defined as a group of points existing on a diagonal of a two-dimensional coordinate consisting of the first one-byte data and the second one-byte data;
• and
• the diagonal has a first endpoint consisting of a minimum value of the first one-byte data and a maximum value of the second one-byte data, and has a second endpoint consisting of a maximum value of the first one-byte data and a minimum value of the second one-byte data.

In an apparatus using a remote control signal, an improvement comprising:

• assigning a first remote control signal to a signal of a remote controller;
• assigning a second remote control signal to a signal of a touch panel, the second remote control signal not overlapping the first remote control signal;
• and
• analyzing a remote control signal to determine if the remote control signal is the first remote control signal or the second remote control signal,
• wherein:
• the remote control signal includes first one-byte data and second one-byte data;
• the first remote control signal exists on a first portion which is defined as a group of points existing on a diagonal of a two-dimensional coordinate consisting of the first one-byte data and the second one-byte data;
• and
• the diagonal has a first endpoint consisting of a minimum value of the first one-byte data and a maximum value of the second one-byte data, and has a second endpoint consisting of a maximum value of the first one-byte data and a minimum value of the second one-byte data.
