Its structure is easy to see, it is used to separate the device brightness and color output. Why do this? This is designed primarily to overcome interference composite output video program when the luminance and chrominance. Luminance signal bandwidth of radio and television in general is 6MHz, while the domestic standard PAL color signal bandwidth of 1.5MHz. Composite video output signal is 4.43MHz chroma subcarrier wave frequency is placed between the video luminance signal, chroma demodulation display output, the chroma subcarrier filtered out from the composite video signal, so that you may lose luminance signal 4.43MHz ± 0.75MHz frequency, high-temperature line motor UL product type, reduces the level of clarity. In addition, not completely filtered chrominance subcarrier may interfere with the luminance channel, whereas in the edge of the luminance signal is entered 4.43MHz chroma demodulating circuit, both interfere with each other, reducing the quality of the broadcast. Using S-Video output luminance and chrominance separation can improve the picture quality, high-temperature line motor UL, which is why some people call it "High Definition output" reasons. There are a lot of cards have increased the video output on the installation of video output, the motor UL high temperature wire manufacturer, there are S-Video output and ordinary composite video output. What is S-Video output it? Some people call it "High Definition Output", this argument naturally can not be wrong. Some technical problems S-Video output for interested friends for reference. S terminal is actually a five-pin interface, the two-way video luminance signal, two-way video chrominance signals and one common shield ground altogether five core composition (in fact there is its support of the brightness, chroma separator) ??? UL motor temperature line, preferential plant, motor UL high-temperature line quality assurance by the Dongguan City, Shi Jie Xu Song electronic products factory provided. UL motor temperature line, preferential plant, motor UL high-temperature line quality assurance is Dongguan Shijie Xu Song Chong electronic products factory (chuangxs.1688.com) (www.chuangxs.1688.com) this year introduced a new upgrade, the above picture only for information, please call Tel picture on this page or to obtain the latest information, contact: Mr. Hu.
