What is HDMI? Its types, Structure, Functions, Benefits and losses | HDMI Vs USB, VGA, DVI

Nowadays all LED TVs and computers have an HDMI port. Its job is to send video and audio signals to the monitor in digital format. Now you need to understand about the video format.

The video format is the one on which the video is made. Such as 4K, FULL HD, 720P HD, MP4, 3GP, etc. Now, most of the shooting is done in 4K or Full HD format because you want to see so much clear footage in your TV or computer. HDMI only helps to maintain that clarity.

The functions of HDMI cable:

If you have ever had a small TV, then you will definitely be familiar with the three wires that used to connect your TV to the DVD or cable box.
The colors of these three wires were red, yellow and white. Their work used to reach the video and audio element to your TV.
Now as TVs became bigger and thinner, the method of video and audio transfer also changed. Now those three wires have been replaced by HDMI.
HDMI is a high-speed cable capable of bi-directional work at speeds up to 100 MBPS. And because of this you can see and hear videos of high frame rates and high-quality sound without any interruption.

Structure of HDMI cable:

Structure of HDMI Cable

It is a 19 pin cable which can be of 3 types-
  1. Type A HDMI of  13.9 mm × 4.45 mm                   
  2. Type C HDMI of 10.42 mm × 2.42 mm
  3. Type D HDMI of 6.85 mm × 1.8 mm

Types of HDMI cable:

HDMI cable can be divided into only two types. Their types are kept only on the basis of their speed.

Standard cable: This cable is also called common cable. Its pixel speed is 75 Mhz and its bandwidth is 2.23Gbps. In this type of cable, you can transfer the 1080i signal without any hassle.

High Speed ​​Cable: It is a high-speed cable. Thus the pixel speed of the cable is 340 Mhz and bandwidth is 10.2Gbps. With this cable, you can transfer 1440p and WQXGA resolution signals without any hassle.

Advantages of HDMI:

Intelligence- There is 2-way communication in it which it automatically configures, so you will not need to do any setting. In this, Extended Display Identification Data (EDID) technology is used.

Authentication and encryption: HDMI is the most secure communication so that you can send your signals to the authorized device itself.

Deep colors- HDMI cable provides depths of 10 bit, 12 bit and 16-bit color, which gives you good screen quality and with this you will get good detail using HDMI cable.

With DVI compatibility- You can use DVI Interface in HDMI. You can transmit HD Signal in DVI Enable Pc.

Good Quality: In HDMI, you will get the original quality of all video and audio, as there is no converter used so that it will not affect the signal. Using HDMI cable, you will get to see the best quality video.

CEC- which means Consumer Electronics Control, is a communication link with the help of which you can connect a device with a company.

HD quality- With its help, you can transfer HD video and signal without any hassle.

Disadvantage of HDMI:

Although there is not much loss of HDMI. But if you go to any shop to buy HDMI cable, you will get to know that it is a bit costly. So we can't use it for long-distance because it is expensive.

Difference between HDMI and USB:

HDMI and USB ports look almost the same, but they vary considerably. The work of both is different. Now to understand this difference better, you also need to know about the USB.

USB is a short form of Universal Serial Bus, which has a plug and play interface. With the help of this, computers and devices are able to connect like, mouse, CPU, keyboard, and speaker, etc.

While HDMI work is different from this, it transfers audio and visual elements to the monitor at a high-speed rate in the form of data.

Difference between HDMI, VGA, and DVI:

You must have heard the name of these three often. They are also a connector like HDMI. Let's know the difference between them.
 
VGI-
VGA is the oldest technology among the three, which was created in 1987. It is able to transfer only the visual element. It is unable to transfer the sound element. There is no security management in it.
In this, the quality of the video depends on the quality of the cable, the quality of the pin and the distance of the PC. Its system is an analog system.

HDMI-
HDMI was discovered in 2003 which is mainly found in all large televisions and computers. Gradually, it has now become a part of laptop hardware.
It does not depend on cable quality, pin quality, and PC distance. There will not be any effect on video and sound quality due to inexpensive HDMI cable. But inexpensive cables don't work for a very long time.

DVI:
DVI was created in 1999. It is also similar to VGA and HDMI, and it is analog as well as digital. Actually, with the help of a connector, this can be converted to VGA or HDMI. One drawback in this is that it does not support sound like HDMI. and it also requires separate audio cables for DVI interfacing.

Conclusion: So, this was all about the HDMI, VGI, DVI, and their difference. I hope this article was useful to you. Share the information with your friends and if you have any query or questions, free feel to ask in the comment section.
