Abstract

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.

Claims

1. An apparatus for using remote control signals, 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 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 being 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 being the first remote control signal; and

a touch panel operation processor performing a touch panel processing depending on the remote control signal upon being the second remote control signal.

2. An apparatus of claim 1, wherein:

the remote control signal includes first one-byte data and second one-byte data;

the first remote control signal exists on first portion which is defined as a group of points existing on a diagonal of two-dimensional coordinate consisting of the first one-byte data and the second one-byte data;

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.

3. An apparatus of claim 2, wherein the first remote control signal has the first one-byte data, and has the second one-byte data used to error-correct the first one-byte data thereof.

4. An apparatus of claim 2, wherein:

the second remote control signal has a set of the first one-byte data and the second one-byte data, which indicate a two-dimensional coordinate value corresponding to the two-dimensional coordinate value signal.

5. An apparatus of claim 4, wherein the second remote control signal is transmitted via a cable.

6. An apparatus of claim 1, wherein the two-dimensional coordinate value is corrected to avoid a predetermined special coordinate value which indicates being the second remote control signal.

7. An apparatus of claim 6, wherein the predetermined special coordinate value is a coordinate value indicating an edge portion of the touch panel.

8. An apparatus of claim 6, wherein the predetermined special coordinate value is used in supplying an electric power to the touch panel.

9. 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 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 being 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 being the first remote control signal; and

a touch panel operation processor performing a touch panel processing depending on the remote control signal upon being the second remote control signal.

10. 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 touch; and

a signal generator a second remote control signal from the two-dimensional coordinate value signal, the second remote control signal being not overlapping the first remote control signal.

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

assigning a first remote control signal to a signal of a remote controller; and

assigning a second remote control signal to a signal of a touch panel, the second remote control signal being not overlapping the first remote control signal.
