Abstract

A portable electronic device includes a TV module and a touch screen module. The TV module is used for receiving a first TV image signal on a first selected channel. The touch screen module is in communication with the TV module and controlled by the TV module for displaying a program frame corresponding to the first image signal in a full-screen mode. The TV module receives a second TV image signal on a second selected channel in response to a handwriting operation on the touch screen module during the full-screen mode.

Claims

1. A portable electronic device, comprising:

a TV module for receiving a first TV image signal on a first selected channel; and

a touch screen module in communication with the TV module and controlled by the TV module for displaying a program frame corresponding to the first image signal in a full-screen mode, wherein the TV module receives a second TV image signal on a second selected channel in response to a handwriting operation on the touch screen module during the full-screen mode.

2. The portable electronic device according to claim 1, further comprising an accelerometer in communication with the TV module for detecting a shaking motion, wherein the TV module performs a channel-switching operation in response to the shaking motion.

3. The portable electronic device according to claim 2 wherein if the shaking motion is detected by the accelerometer and the accelerometer has an output value greater than a threshold value, the TV module performs the channel-switching operation.

4. The portable electronic device according to claim 3 wherein when the channel-switching operation is performed, a current selected channel is switched to a previous selected channel.

5. The portable electronic device according to claim 1 wherein the channel-switching operation is performed by handwriting a numeral symbol on the touch screen module, wherein if the numeral symbol is recognized by the touch screen module, the touch screen module generates a channel-switching signal to the TV module, and the TV module receives the second TV image signal on the second selected channel in response to the channel-switching signal.

6. The portable electronic device according to claim 5 wherein the touch screen module determines not to generate the channel-switching signal if the number symbol fails to be recognized by the touch screen module within a specified time interval.

7. The portable electronic device according to claim 5 wherein the touch screen module determines not to generate the channel-switching signal if the numeral symbol recognized by the touch screen module is not included in a channel selection menu.

8. A channel-switching method for use with a portable electronic device having a touch screen module, the channel-switching method comprising steps of:

receiving a first TV image signal on a first selected channel;

displaying a program frame corresponding to the first image signal on the touch screen module in a full-screen mode; and

receiving a second TV image signal on a second selected channel in response to a handwriting operation on the touch screen module during the full-screen mode, so that another program frame corresponding to the second image signal is displayed on the touch screen module in the full-screen mode.

9. The channel-switching method according to claim 8 wherein a channel-switching operation is performed in response to a shaking motion of the portable electronic device.

10. The channel-switching method according to claim 9 wherein when the channel-switching operation is performed, a current selected channel is switched to a previous selected channel.

11. The channel-switching method according to claim 8 wherein the channel-switching operation is performed by handwriting a numeral symbol on the touch screen module, wherein if the numeral symbol is recognized by the touch screen module, the touch screen module generates a channel-switching signal to the TV module, and the TV module receives the second TV image signal on the second selected channel in response to the first channel-switching signal.

12. The channel-switching method according to claim 11 wherein the channel-switching signal is not generated by the touch screen module if the number symbol fails to be recognized by the touch screen module within a specified time interval.

13. The channel-switching method according to claim 11 wherein the channel-switching signal is not generated by the touch screen module if the numeral symbol recognized by the touch screen module is not included in a channel selection menu.

14. A portable electronic device, comprising:

a TV module for receiving a first TV image signal on a first selected channel; and

a touch screen module in communication with the TV module and controlled by the TV module for displaying a program frame corresponding to the first image signal in a full-screen mode, wherein a channel information is displayed on the touch screen module in response to a handwriting operation on the touch screen module during the full-screen mode.
