Set-top box port number query
Except TVs with built-in digital TV set-top boxes, most TVs use analog video. This article will introduce the types of TV interfaces to help you choose the right interface and enjoy high-definition picture quality.

Analog interface

Red, yellow and white lines are common analog interfaces, while red, blue and green lines are component interfaces. These interfaces are all analog interfaces, except for the network cable and USB interface.

Component interface

Red, blue and green lines are component interfaces, which can transmit red, blue and green signals respectively, thus improving the clarity and color reproduction of the picture.

Special interface

In addition to analog interfaces, there are various interfaces with special shapes, such as HDMI and S interfaces. These interfaces can transmit digital signals to ensure high-definition image quality.

Radio frequency port

If there is only one external antenna interface left on the TV, it is the RF port. This interface can only transmit analog signals, and the picture quality is poor, so it is not suitable for watching high-definition videos.

Choose the right interface and enjoy high-definition image quality.

When buying a TV, be sure to carefully check the interface type to ensure that it can meet your needs. Choose the right interface and enjoy the visual feast brought by high-definition image quality.
