There are many types of video cable connectors, including: AV interface (composite audio and video), S-Video interface (separate video), VGA interface (analog signal transmission), HDMI interface (fully digital video and sound) , and BNC interface (used by professional video equipment).
There are many types of video cable connectors, the following are some of the common types:
AV interface (RCA ): This is a composite audio and video interface, consisting of red, white, and yellow wires. Among them, the yellow wire is used for video transmission, while the red and white wires are responsible for sound transmission of the left and right channels respectively. This interface is more common on older TVs and audio-visual equipment.
S-Video interface: This is a separate video interface that separates and outputs brightness and chrominance signals, avoiding brightness and chroma interference that may occur when mixing video signals. The S-Video interface usually consists of four or five cores and can transmit higher quality video signals.
VGA interface: also called D-Sub interface, it is used to transmit analog signals, including red, green, blue analog signals and synchronization signals. The VGA interface is very common on computer monitors. The interface looks like a "D" and has a total of 15 pinholes divided into three rows of five.
HDMI interface: HDMI is a fully digital video and sound transmission interface that can send uncompressed audio and video signals. It is widely used in consumer electronics such as set-top boxes, DVD players, personal computers and televisions.
BNC interface: This is a coaxial nut interface, consisting of RGB three primary color signals and five independent signal connectors for horizontal synchronization and vertical synchronization. BNC interfaces are usually used in professional video equipment, such as security monitoring systems.
In addition, there are other types of video cable connectors, such as SDI interface, DVI interface, etc. These interfaces have their specific application scenarios and advantages. When selecting a video cable connector, you need to consider device compatibility, transmission quality, and usage requirements.
