TV Ports Guide, What're Their Functions?


HDMI interface:

The HDMI port is a must in the high-definition digital era, not only able to meet the full HD resolution of 1080p but also support DVD Audio and other digital audio formats. HDMI's plug-and-play devices, which can transmit up to 15 meters, are both convenient and powerful.

VGA interface:

VGA(Video Graphics Array) is the interface for transmitting analog signals to display devices. It is believed that most people are in contact with computer monitors. Since the CRT display era, the VGA interface has been used and is still in use today.

Optical fiber Audio interface:

Optical fiber audio interface TosLink, full name Toshiba Link, is a technical standard developed and set earlier by Toshiba Of Japan. Optical is marked on the back of audiovisual equipment. The ray-audio interface is absolutely optimized not only for graphics but also for audio.

LAN network interface:

With the deepening of the network, our daily life has been closely related to the network, the lack of the network seems to be a little disconnected from the world, so, at present, most flat panel TV equipped with LAN network interface, TV is a common RJ-45 interface


Displayport interface:

DisplayPort is an interface specification approved by the Video Electronics Standards Association (VESA). DisplayPort is free of licensing fees and aims to leapfrog DVI and HDMI interface technologies in several areas. DisplayPort leverages the electrical layer of PCI Express, which currently operates at 2.5Gbps, to get up to 10.8Gbps of bandwidth across four channels. DisplayPort will be able to transfer HD audio signals alongside video signals, with higher resolution and refresh rates.

AV interface:

AV interface is one of the earliest interfaces to achieve audio and video separation. It is composed of red, white and yellow lines. Yellow lines are video transmission lines, and red and white lines are responsible for the sound transmission of the left and right channels.

Separate Video interface:

S-video connection specification is a specification developed by Japanese, S stands for "Separate", it will be brightness and chroma Separate output, avoid mixed Video signal output brightness and chroma interference. S terminal is actually a five-core interface, consisting of five core wires, two video brightness signals, two video chroma signals and one public shielding ground wire.


The color difference component interface adopts YPbPr and YCbCr. The former indicates progressive scan color difference output, and the latter indicates interlaced scan color difference output. To put it simply, chromatic aberration is the input of red, green and blue as opposed to AV and S terminals.
