INSTRUCTIONS (1) [Technical field of invention 4 浐 ί : Ming system: There are video output test systems, systems, methods and devices, especially the test of the image wheel * I set the image of S Whether it is a good test system, method and device. /, 疋 [Before the technology is equipped with a composite direct input with high-frequency card, the signal is usually also included in the Out), thinking that AV (Aud is the original color line merged. Currently Video In and chroma signal can be Only the TVs whose brightness is transmitted separately for the two-point operation have only the video input and output and the output demodulated amount. The video input terminal does not contain the audio signal. The audio input, the audio transmission, and the synchronous transmission of the sound i 〇 V i deo ) terminal - when it is in the signal color, and this complex antenna input 埠, the new TV set (Video In, Video Out), to the video signal, because the video signal is not simple, Therefore, the video of the computer gets the video signal. Also, because of the video, it is generally difficult to reproduce with the video input and output end (Audio-in, Audio-signal, so the composite video interface is also called 'however' the brightness and chroma of the composite video. Restoring a fully identical video signal. Generally, only 240 scanners have a two-component video input 埠 (s _ ^, which can output a two-component video signal, which divides the luminance number into two independent analog signals. The two wires are respectively recorded on the two tracks of the analog tape. This signal does not have a wide bandwidth with the chromaticity, and the interference can be reduced due to the brightness and chromaticity, and the scanning line Up to 4 2 〇 bars, making the video signal more reproducible than the composite video signal
