Introduction To The Different Roles Of Different Interfaces On The TV

Introduction to the different roles of different interfaces on the TV

USB interface: channel of external storage device

I believe that everyone is very concerned about whether flat-panel TVs can achieve streaming media playback. Of course, to achieve this function, you must first have a USB interface. Although many flat-panel TVs are equipped with a USB interface, the functions that can be achieved when connected to a storage device are not the same. Some TVs only support the playback of pictures, while others can play HD video and music files.

The USB interface on the flat-panel TV can realize streaming media playback.

USB was jointly proposed by Intel, Compaq, IBM, Microsoft and other companies at the end of 1994. Since its introduction in 1996, it has successfully replaced serial ports and parallel ports, and has become a mandatory interface for today's personal computers and a large number of smart devices. one. Since the release of the USBV version 0.7 on November 11, 1994, the USB version has undergone years of development and has now evolved to version 3.0.

USB interface definition

Although the interface on the flat-panel TV is currently version 2.0, due to the different decoding capabilities of the TV itself, the file formats that can be played by different models of different models are also different. Here, it is necessary to mention the USB streaming media. Domestic TV is generally stronger than foreign TV.

VGA interface: commonly used to connect to a computer

VGA (VideoGraphicsArray) is the interface to transmit analog signals to the display device. I believe that most of the contacts are on the display of the computer. Since the era of CRT displays, the VGA interface has been used and has been in use ever since.

VGA is an interface commonly used to connect to a computer

Many people think that only the HDMI interface can transmit HD signals, but this is a misunderstanding that everyone can easily enter, because the VGA connection can also display 1080p images, even the resolution can be higher, so use it to connect the display device. There is no problem when watching HD video, and although it is an analog interface, since the VGA decomposes the video signal into R, G, B primary colors and HV line signals for transmission, the loss in transmission is still quite small.

VGA cable

The current flat-panel TVs all have a VGA interface, so that users can use the computer in the home as an input device to output images to the TV. Although the HDMI interface is more powerful than the VGA interface, not all consumers' computers are equipped with an HDMI interface, so the VGA interface is very necessary.
