AV cable
This is the oldest video cable that transmits analog video signals. Both ends are RCA connectors. Both DVD players and TVs will have this kind of interface. It is not necessary to wire this cable during decoration.
S terminal cable
A few years ago, the video cable with better quality than the AV cable, the interface is round, similar to the PS2 mouse head.
Trichromatic line
A video cable with better quality than the S-terminal cable, which transmits analog signals, should be the best video cable among analog signals. New DVD players, high-end TVs, and home projectors will all have this interface.
VGA cable
It is also an analog signal video cable, which is most commonly used in computers. Compared with the color difference line, its signal has its own merits. However, as the amount of video data increases, for example, 1920X1080P video signals will be transmitted in the future, the redundancy of the color difference line will be greater. , After the resolution exceeds 1600X1200, the quality of the VGA cable is slightly inferior, and the length is slightly longer, which will cause snowflakes. Why do home theaters mention VGA cables? That's because HTPCs have entered home theaters, and all projectors have VGA ports.
DVI cable
The full name of Digital Visual Interface, the latest digital video line, transmits all digital signals with uncompressed technology, the maximum transmission speed is 8Gbps, and has been supported by most manufacturers of digital video signal lines. The transmission speed of the interface is as high as 8Gbps, and its interface has 24+1 (DVI-D), 24+5 (DVI-I) type, DVI-I supports simultaneous transmission of digital (DVI-D) and analog signals (VGA signal). Generally speaking, HTPC graphics cards are generally DVI-I interfaces, while LCD monitors and projectors have a DVI-D interface. Although the DVI-I interface is compatible with the DVI-D interface, the DVI-I plug cannot be inserted into the DVI-D interface. Why? There are four more pins. But we still have a way, using a DVI-I to DVI-D converter.
HDMI cable
The full name is Hi-Definition Multimedia Interface. It is a newer digital video cable than DVI. It transmits all digital signals with uncompressed technology. The maximum transmission speed is 3.95Gbps. In addition to transmitting video, HDMI also supports eight-channel 96kHz or mono 192kHz digital. For audio transmission, there are not too many devices that support HDMI. Its interface can be converted with DVI interface (video signal part).
