What kind of video interface and its quality? Is it divided into analog interface and digital interface?

The types of video interfaces can be roughly divided into analog interfaces and digital interfaces. Commonly used are:

Typical analog interface: the full name of S-Video interface is separated video, also known as super video. It is actually a five-core interface, which consists of two video brightness signals, two video chroma signals and five cores of a common * * * shielded ground wire. And YPbPr /YCbCr color difference interface.

Typical digital interface: HDMI interface, full name is high-definition multimedia interface, which can support the transmission of video and audio. It belongs to digital signal and is the mainstream compatible video interface type at present. Television, computer, monitor, notebook, projection equipment, etc. Basically, there is an HDMI interface.

Video Compatible Digital and Analog Interfaces Advantages:

1, the composite video signal (CVBS) interface is also called AV interface or video interface. It is a video interface with separated audio and video, generally consisting of three independent RCA plugs (also called Lotus interface and RCA interface).

This is a mixed video signal with good fidelity. The image quality is greatly influenced by the wire used, and the resolution can generally reach 350~450 lines. It can also be used in digital display equipment, which requires a process of converting analog signals into digital signals.

2.DVI interface

The full name of DVI is digital visual interface. At present, DVI interfaces are divided into two types:

One is DVI-D interface, which can only receive digital signals. There are only 3 rows, 8 columns and 24 pins on the interface, and one pin in the upper right corner is empty. Incompatible analog signal.

The other is DVI-I interface, which is compatible with both analog and digital signals.

DVI interface has two main advantages:

High bandwidth: DVI can directly transmit digital signals without complicated conversion between analog signals and digital signals, which is faster and effectively eliminates smear phenomenon.

Clear picture: DVI transmits digital signals, without complicated conversion between analog signals and digital signals, which avoids the loss of signals, makes colors more pure and realistic, and improves the clarity and detail expression of images.
