Abstract

A multimedia processing system includes a selector, an output playback apparatus, a controller, and an A/V signal detector. The selector has a plurality of input ports for receiving multimedia signals and for selecting and outputting one of the multimedia signals according to a selection control signal. The output playback apparatus is used for playing the multimedia signal outputted by the selector in the output playback apparatus. The controller is used for generating the corresponding selection control signals to the selector. The A/V signal detector is used for detecting whether the input ports of the selector have received a newly inputted multimedia signal. When a newly inputted multimedia signal is detected, the A/V signal detector outputs a specific selection signal to the controller, so the controller subsequently generates the corresponding selection control signal to the selector for selecting and outputting the newly inputted multimedia signal to the output playback apparatus.

Claims

1. A multimedia processing system comprising:

a selector comprising a plurality of input ports for receiving a plurality of multimedia signals from different signal sources and for selecting and outputting one of the multimedia signals according to a selection control signal;

an output playback apparatus for processing the multimedia signal outputted by the selector and playing the processed multimedia signal in the output playback apparatus;

a controller for generating the corresponding selection control signals to the selector according to different selection signals; and

an audio and/or video (A/V) signal detector for detecting whether the input ports of the selector has received a newly inputted multimedia signal;

wherein when detecting the newly inputted multimedia signal, the A/V signal detector outputs a specific selection signal to the controller, so that the controller subsequently generates the corresponding selection control signal to the selector for selecting and outputting the newly inputted multimedia signal to the output playback apparatus, so as to be auto-played.

2. The multimedia processing system of claim 1, wherein each of the multimedia signals inputted to the selector is a video signal, an audio signal, or a mixed signal including a video signal and an audio signal.

3. The multimedia processing system of claim 2, wherein the output playback apparatus is a video playback apparatus for processing the video signal or the mixed signal including the video signal and the audio signal outputted by the selector and for playing the processed signal in the video playback apparatus.

4. The multimedia processing system of claim 3, wherein the video playback apparatus is a TV set or a computer display screen.

5. The multimedia processing system of claim 3, wherein the A/V signal detector plays a pop-up menu on the video playback apparatus when detecting that the newly inputted multimedia signal appears, and the pop-up menu plays the multimedia signals currently received by the selector in corresponding options for user selection.

6. The multimedia processing of claim 1, wherein one input port of the selector is connected to a multimedia signal from a cable TV channel.

7. The multimedia processing of claim 6, wherein when detecting that the newly inputted multimedia signal appears, the A/V signal detector switches the selector to the multimedia signal from the cable TV channel and outputs the multimedia signal to the output playback apparatus.

8. The multimedia processing of claim 1, wherein the controller is connected to an input panel comprising a plurality of selection keypads for a user to generate a second input control signal to the controller.

9. The multimedia processing of claim 1, wherein the multimedia processing system comprises an infrared remote controller including a plurality of selection keypads thereon for a user to generate a first input control signal to the controller via infrared transmission.

10. The multimedia processing of claim 1, wherein the output playback apparatus is an audio playback apparatus for playing the output signals from the selector to a speaker.

11. An auto-detection/selection method for audio/video signals in a multimedia processing system, the multimedia processing system comprising:

a selector comprising a plurality of input ports for receiving a plurality of multimedia signals from different signal sources and for selecting and outputting one of the multimedia signals according to a selection control signal;

an output playback apparatus for processing the multimedia signal outputted by the selector and playing the processed multimedia signal in the output playback apparatus; and

a controller for generating the corresponding selection control signals to the selector according to different selection signals;

wherein when detecting the newly inputted multimedia signal, the auto-detection/selection method outputs a specific selection signal to the controller, so that the controller subsequently generates the corresponding selection control signal to the selector for selecting and outputting the newly inputted multimedia signal to the output playback apparatus, so as to be auto-played.

12. The auto-detection/selection method of claim 11, wherein each of the multimedia signals inputted to the selector is a video signal, an audio signal, or a mixed signal including a video signal and an audio signal.

13. The auto-detection/selection method of claim 12, wherein the output playback apparatus is a video playback apparatus for processing the video signal or the mixed signal including the video signal and the audio signal outputted by the selector and for playing the processed signal in the video playback apparatus.

14. The auto-detection/selection method of claim 13, wherein the video playback apparatus is a TV set or a computer display screen.

15. The auto-detection/selection method of claim 13, wherein a pop-up menu is played on the video playback apparatus when detecting that the newly inputted multimedia signal appears, and the pop-up menu plays the multimedia signals currently received by the selector in corresponding options for user selection.

16. The auto-detection/selection method of claim 11, wherein one input port of the selector is connected to a multimedia signal from a cable TV channel.

17. The auto-detection/selection method of claim 16, wherein when detecting that the newly inputted multimedia signal appears, the selector is switched to the multimedia signal from the cable TV channel and the multimedia signal is outputted to the output playback apparatus.

18. The auto-detection/selection method of claim 11, wherein the controller is connected to an input panel comprising a plurality of selection keypads for a user to generate a second input control signal to the controller.

19. The auto-detection/selection method of claim 11, wherein the multimedia processing system comprises an infrared remote controller including a plurality of selection keypads thereon for a user to generate a first input control signal to the controller via infrared transmission.

20. The auto-detection/selection method of claim 11, wherein the output playback apparatus is an audio playback apparatus for playing the output signals from the selector to a speaker.
