Abstract

A testing system and a method thereof are provided. The testing system includes an audio/video playback apparatus and a testing apparatus. The audio/video playback apparatus is configured to receive an audio/video signal, and analyze the audio/video signal to generate a signal analysis result and a processed audio/video signal. The processed audio/video signal is configured to be displayed on a screen of the audio/video playback apparatus. The testing apparatus includes a switching module and a determining unit. The switching module controls at least one audio/video transmission interface of the audio/video playback apparatus, so as to select and transmit the corresponding audio/video signal to the audio/video playback apparatus. When the switching module transmits the audio/video signal to the audio/video playback apparatus, the determining unit receives and analyzes the signal analysis result, so as to determine whether the processed audio/video signal is normally processed by the audio/video playback apparatus.

First claim

What is claimed is:

1. A testing system, comprising:
an audio/video playback apparatus, configured to receive an audio/video signal, and analyze the audio/video signal to generate a signal analysis result and a processed audio/video signal, wherein the signal analysis result is corresponding to information required in testing, wherein the processed audio/video signal is configured to be displayed on a screen of the audio/video playback apparatus; and
a testing apparatus, comprising:
a switching module, controlling at least one audio/video transmission interface of the audio/video playback apparatus, so as to select and transmit the corresponding audio/video signal to the audio/video playback apparatus; and
a determining unit, receiving and analyzing the signal analysis result when the switching module transmits the audio/video signal to the audio/video playback apparatus, so as to determine whether the processed audio/video signal is normally processed by the audio/video playback apparatus.

2. The testing system of claim 1 , wherein the at least one audio/video transmission interface comprises a radio frequency interface, a video graphic array interface, a composite video blanking and sync interface, a high definition multimedia interface and a component video terminal interface.

3. The testing system of claim 1 , wherein the audio/video playback apparatus executes a testing procedure, and the testing procedure controls the audio/video playback apparatus through a controlling module to analyze the audio/video signal according to the at least one audio/video transmission interface.

4. The testing system of claim 1 , wherein the audio/video playback apparatus comprises an audio/video processing unit configured to analyze whether the audio/video signal is received, test a receiving signal intensity corresponding to the audio/video signal and a value and a chroma of each color in the audio/video signal.

5. The testing system of claim 1 , wherein the audio/video playback apparatus comprises an audio/video processing unit displaying the processed audio/video signal on the screen of the audio/video playback apparatus after the determining unit of the testing apparatus determines that the processed audio/video signal is normally processed by the audio/video playback apparatus.

6. The testing system of claim 1 , wherein the signal analysis result comprises normal signal, no signal, black frame, snowy screen/grainy, ghosting/multi-path/double image, blockiness, blurring, mosquito noise, moire/ripple, color shift and/or a combination thereof.

7. A testing method, suitable for a testing system including an audio/video playback apparatus and a testing apparatus, and the testing method comprises:
controlling at least one audio/video transmission interface of the audio/video playback apparatus, so as to select and transmit the corresponding audio/video signal to the audio/video playback apparatus; and
receiving and analyzing a signal analysis result from the audio/video playback apparatus, so as to determine whether a processed audio/video signal is normally processed by the audio/video playback apparatus, wherein the signal analysis result is corresponding to information required in testing;
wherein the audio/video playback apparatus receives the audio/video signal, and analyzes the audio/video signal to generate the signal analysis result and the processed audio/video signal, wherein the processed audio/video signal is configured to be displayed on a screen of the audio/video playback apparatus.

8. The testing method of claim 7 , wherein the at least one audio/video transmission interface comprises a radio frequency interface, a video graphic array interface, a composite video blanking and sync interface, a high definition multimedia interface and a component video terminal interface.

9. The testing method of claim 7 , wherein the audio/video playback apparatus executes a testing procedure, and the testing procedure controls the audio/video playback apparatus through a controlling module to analyze the audio/video signal according to the at least one audio/video transmission interface.

10. The testing method of claim 7 , wherein the audio/video playback apparatus comprises an audio/video processing unit configured to analyze whether the audio/video signal is received, test a receiving signal intensity corresponding to the audio/video signal and a value and a chroma of each color in the audio/video signal.

11. The testing method of claim 7 , wherein the audio/video playback apparatus comprises an audio/video processing unit displaying the processed audio/video signal on the screen of the audio/video playback apparatus after the testing apparatus determines that the processed audio/video signal is normally processed by the audio/video playback apparatus.

12. The testing method of claim 7 , wherein the signal analysis result comprises normal signal, no signal, black frame, snowy screen/grainy, ghosting/multi-path/double image, blockiness, blurring, mosquito noise, moire/ripple, color shift and/or a combination thereof.
