The test data library 40 enters the digital audio test function 43, and the digital fiber connector 32 of the pixel receiving device 30 outputs the digital sound signal carried by the digital television signal to the sound effect by using the optical fiber communication module j. The card 35, the sound card 35 converts the optical fiber communication signal into an electrical signal to analyze the digital sound source signal, and is received by the usb 埠1Π a of the control module n. Second, the test database 40 executes a digital audio test environment 43〇, the sixth picture, wherein the sine waveform 431 represents the sound card % output 15 = bit sound number, the lower phase shows the maximum amplitude of the sound, Test data 432 such as sound frequency, and the function value of the waveform value of the test data library is divided into two parts, and the test value is compared with the digital audio specification parameters defined in step 2, so that the audio and video reception can be verified. Whether the digital fiber connector 32 of the device 3 and the sound card 35 can operate normally and whether the electrical characteristics of the device 2 are in compliance with the specifications, if they are all met, a green light will appear on the PASS display item 433, otherwise a yellow light will appear and fail A red light warning will appear on each electrical item of the test specification. 8. The test database 4 enters the above analog video test function, and the control module 11 sends a digital control signal through the USB port to the π 200803463 clamp circuit 21 'to make the analog output of the switch module 2 The group 26 sends the image signal to the data capture module 12. ^ The test database 4 performs a video test environment, and the seventh picture is taken, wherein the color bar waveform 441 represents that the video output group 33 inputs 5 (four) video signals 'below the gray level and the ternary color (R) /G/B) test data 442, and the test data library * towel for the numerical analysis of the waveform of the data 疋 _ test value, and step 2 mosquito sense to find some video specifications parameters, so it can be used to check the sound and sound pure device 3G search output, 3+3 can operate normally and infer whether its electrical characteristics are in compliance with the rule 0. If it meets, it will display green light on PASS display item 443, otherwise it will appear yellow light, and it will not pass the test specification. Two lights warnings will appear on all electrical items. 10. The test database 40 further cooperates with the data capture function of the data capture device, and performs the tearing of the CVBS. The analysis environment, the eighth figure refers to the R/G/B. The color is determined separately by waveform determination and color scale determination, and the R/G/B standard standards of the video specification parameters defined in step 2 are compared with the extracted values to determine whether the standard specifications are met. If all are met, a green light will appear on the PASS display item, otherwise a yellow light will appear, and a red light warning will appear for each electrical Q item that has not passed the test specification. 11. The test database 40 enters the panel operation test function 45 and executes a panel test environment 450. The reference to the ninth figure shows that all the function buttons 36 actually corresponding to the panel of the video-receiving device 30 are available for initial operation. Each command light is in a red state.

If the correct f will be green, the job is limited to purchase-key first Wei, and each function 5 can be tested by 36. • The measurement and reduction data S 40 returns to the initial test interface as shown in the fourth figure. The hardware connection test function 4 ^ shows whether the system hardware is connected or not. The analog audio test Wei 42 and the digital audio test function 43 The analogy test function 44 and the panel operation test function 45 display steps 1〇4 to 11 and the final _ is all good, if both are in the state, the column 46 displays the entire test state' and the green light appears in the PASS display item. , ^ will appear yellow light, and failed to pass the test specification for each t gas item red light warning. θ Therefore, the present invention completely performs all electrical and device function tests of the video/audio receiving device 30 through the test database 40. The test environment displays the characteristics of the video receiving device and the signal transmission with a signal waveform, and has a clear discriminating light. The number shows the test results for the user to get the test results quickly and correctly. It is worth mentioning that when the digital TV system can provide a wider frequency band or a digital TV minus time, the receiving user terminal often needs to cooperate with two set-top boxes for the lower level without _ (four) _ processing, so The video test system 2 for testing a plurality of video receiving devices according to the second preferred embodiment of the present invention is further provided by the device according to the second preferred embodiment of the present invention. The video receiving device 50 has the same structure as the video receiving device 3〇13 200803463, and has a video receiving end group 51, a digital fiber connector 52, a video, an audio output group 53, 54 and a plurality of function buttons. %, so the system connection is further known by the video receiving end group 51 receiving device - the surface is mixed 37, tender = the; ^ = connected to the sound card 35, the video output terminal group 53 is electrically connected, and The audio input group 24 is electrically connected to the audio input group 25 of the switching module 2, and one of the control modules U is electrically connected to the video receiving device. 5〇's command communication bee (the picture is like the step of the financial class) Audio and video connection = 3 〇, 5 〇 output image and audio signal signal characteristics and its function 15 20 ” 1.

The test data library 5 executes the audio test environment 420, the twelfth = photo, compared to the above implementation Step 5 of the example is the #娜娜 module 12: the audio-visual receiving device 30, 5 〇 different frequency audio signal area knife mouth member is taken out, thus more sinusoidal waveform output by the video receiving device % 421, the assignment data 422, and the pASS display item 423. The test database 60 is inserted into the digital audio test function 43, and the sound card 35 can simultaneously set the number two digits compared to the step 6 of the embodiment. 15 The optical fiber track signals output by the optical fiber connectors 32 and 52 are converted into electrical signals, and are received by the USB port 111 a of the control module 11. 7. The test data library 6 executes a digital audio test environment 430, and the thirteenth figure refers to the data capture module, and the video capture device 30 can be used for the video capture device 30, The sound signal zone cutters of 50 different frequencies are taken out, so that the sinusoidal waveform 431, the test data 432, and the PASS display item 433 output by the video receiving device 50 are more. The remote test data library enters the analog video test function 44, and the image signal of the video receiving device 30, 50 is sent to the analog output terminal group 26 of the switching module 20 to the data. The module 12 is captured. 9.
