What is the difference between HDMI high-definition cable and ordinary cable? Many people have gradually discovered that many electronic devices in our lives have gradually added an HDMI high-definition cable interface, such as our TVs, computers, etc., will have HDMI interfaces, many friends I don’t know what the HDMI interface is for. What is the difference between HDMI high-definition cable and ordinary cable? Today, Jianghan Electronics will tell you what the difference is.

　　Different resolution:

　　1, ordinary video cable: support 576P resolution;

　　2, HDMI high-definition cable: support 1080P high-definition video.

　　Support different channels

　　1. Ordinary video cable: does not support 8-channel 96kHz or mono 192kHz digital audio transmission;

　　2, HDMI high-definition cable: supports 8-channel 96kHz or mono 192kHz digital audio transmission.

　　Other differences:

　　1, the physical properties of the insulating layer are different;

　　2, the core wire diameter is different;

　　3. The above two fundamental differences determine the transmission characteristics of the two cables-the transmission attenuation is different;

　　4. The obvious characteristics of high braided cables are: low DC resistance of the shielding layer and reduced low-frequency attenuation below 200KHz, which is beneficial to suppress low-frequency interference. In terms of frequency distortion, high braided cables are more serious. The direct influence of frequency distortion is the normal proportional distortion of the various frequency components of the video signal, which directly affects the image distortion;

　　5. Copper-clad steel core wire: This is a type of SYWV cable, used for radio frequency transmission above 46MHz for CATV, and the 0-200KHz low frequency attenuation is too large.

　　The above is the difference between HDMI high-definition cable and ordinary cable. If you are buying HDMI high-definition cable, you must first check whether your device supports HDMI function, because some devices still do not support HDMI high-definition cable.
