CVBS is short for Composite Video Broadcast Signal. This is the most common video Interface, the first application in the field of radio and television, then a lot of camera output support the CVBS interface, CVBS signals are interlaced video signal, and a Resolution of 720 x576 (PAL) or 720 x480 (NTSC), CVBS is the analog video Signal Interface, has gradually been digital video signal interface and replace the hd video signal interface.

RCA interface: Composite video signal (CVBS) interface, commonly known as lotus socket, also known as AV terminal, also known as AV interface, is usually a pair of white audio interface and yellow video interface, RCA connector is by far the most common kind of sound/video terminal. RCA audio terminals are usually color-coded in pairs: red for right channel and black or white for left channel.

AV video interface English full name is: "Composite video connector", AV terminal is usually consists of three lines, transmission of video is usually yellow RCA terminal, the other with two red and white RCA terminal transmit audio, transmitted in AV terminal is analog TV signal source of three elements: Y, U, V, as well as the benchmark of the pulse signal synchronization.

BNC (coaxial cable card ring interface) is mainly used to connect high-end home theater products and professional video equipment. The BNC cable has five connectors that receive red, green, blue, horizontal and vertical synchronization signals respectively. The BNC connector allows the video signals to interfere with each other less to achieve the best signal response.

The Video Graphics Array is also known as D-SUB. VGA interface has 15 pins, divided into 3 rows with 5 holes in each row. It is the most widely used interface type on video CARDS, and most video CARDS have this interface. It transmits red, green, and blue analog signals as well as synchronous signals (horizontal and vertical).

DVI is called Digital Visual Interface. At present, there are two kinds of DVI interfaces. One is the DVI-D (Digital, so-called pure Digital) interface, which can only receive Digital signals. There are only three rows and eight columns on the interface, with a total of 24 pins.
