Abstract

The present invention discloses a system for simultaneously showing TV images and video camera images and method of the same, the system comprises: a TV interface device for receiving TV image signals; at least one video camera signal receiving device for capturing video camera image signals; at least one multiplexing circuit-switch device connected to the TV interface device and the video camera signal receiving device for receiving the TV image signals and the video camera image signals from the TV interface device and the video camera signal receiving device respectively, and further switching the TV image signals and the video camera image signals; an audio and video capturing chip device connected the multiplexing circuit-switch device to receive and process signals from thereon; and an interface circuit device connected the audio and video capturing chip device with an external display device, such as a computer screen. Via the method and the system of the present invention, TV image signals and video camera image signals are thus shown on a same display device at the same time for users'"'"' convenience.

Claims

1. A system simultaneously showing TV images and video camera images comprising:

a TV interface device for receiving TV image signals;

at least one video camera signal receiving device for capturing video camera image signals;

at least one multiplexing circuit-switch device connected the TV interface device and the video camera signal receiving device for receiving the TV image signals and the video camera image signals from the TV interface device and the video camera signal receiving device respectively, and further switching the TV image signals and the video camera image signals;

an audio and video capturing chip device connected the multiplexing circuit-switch device for receiving and processing signals from thereon; and

an interface circuit device connected the audio and video capturing chip device with an external display device.

2. The system simultaneously showing TV images and video camera images as cited in claim 1, wherein the system can be built up in a PC.

3. The system simultaneously showing TV images and video camera images as cited in claim 1, wherein the TV interface device is a TV interface card.

4. The system simultaneously showing TV images and video camera images as cited in claim 1, wherein the video camera signal receiving device is a monitoring video camera.

5. The system simultaneously showing TV images and video camera images as cited in claim 1, wherein the interface circuit device is a displaying card.

6. The system simultaneously showing TV images and video camera images as cited in claim 1, wherein the external display device is a PC screen.

7. A method for simultaneously showing TV images and video camera images comprising the following steps:

(a);

inputting individually the TV image signals and the Video camera image signals to their own assigning and processing module;

(b);

each individual assigning and processing modules engaging weighting processes with the TV image signals and the video camera image signals respectively;

(c);

inputting weighted processed image signal streams to a multiplexing module for composing an assembling image signal string;

(d);

inputting the assembling image signal string to a vertical synchronizing detecting module for capturing image signal streams;

(e);

outputting the captured image signal streams to an external display device via a interface circuit.

8. The method for simultaneously showing TV images and video camera images as cited in claim 7, wherein the interface circuit is a displaying card.

9. The method for simultaneously showing TV images and video camera images as cited in claim 7, wherein the external display device is a PC screen.
