USB, DVI, HDMI Connectors - Application Field and Working Principle

Introduction

USB, DVI, and HDMI connectors allow the connection of two devices, such as a computer and a monitor for example. To ensure that the two devices are compatible, each connector has a specific purpose and must be matched with corresponding devices. In this article, we will look at the applications, technical characteristics and working principles of these three connectors.

USB Connectors

A USB (Universal Serial Bus) connector is one of the most popular connectors used today, allowing the connection of many devices including digital cameras, smartphones, handheld devices, printers, and external hard drives. It translates data from one device to another, and also provides power from a power source such as a laptop or a USB charging block.

USB connectors are classified into different types, based on their shape and the amount of pins they have. The most common type is type A, which is square-shaped with four pins. Other types such as type B, mini-USB, and micro-USB are also available, with different shapes and pin numbers.

DVI Connectors

DVI (Digital Visual Interface) connectors are used to connect displays and other devices such as digital cameras and set-top boxes. The main application field for DVI connectors is computer graphics, for example connecting a computer monitor and a graphics card.

DVI connectors come in two types: DVI-D and DVI-A. DVI-D has 24 pins for digital video and usually supports resolutions up to 1920x1080. DVI-A has fewer pins (4 pins) and supports lower resolutions (640x480).

HDMI Connectors

HDMI (High Definition Multimedia Interface) connectors are mainly used for high-definition video and audio. They have 19 pins and are used to connect devices such as Blu-ray players and HDTVs, and even computers and mobile devices.

HDMI connectors come in three types: Standard, Mini, and Micro. Standard HDMI is usually used to connect home theater systems, while Mini HDMI is used to connect small devices such as digital cameras and smartphones. Micro HDMI is commonly found on the latest tablets.

Working Principle

USB connectors use a universal serial bus interface system to connect devices together. Data is sent and received through USB ports, which are found on the back or side of most computer systems.

DVI connectors send digital data between the source and the display device. Data is transmitted from the source device (host) to the display device (sink). The connectors use a high-speed serial communication protocol to transfer data.

HDMI connectors use a serial digital interface system for video, audio, and control signals. The data is encoded using 8-bit transport coding, and is then transmitted over 19 pins in the connector. The data is routed over twisted-pair cables to the right devices.

Conclusion

USB, DVI, and HDMI connectors are all used to connect devices together. Each of them has a specific application field, and they all work using different communication protocols. Knowing the basics of each connector will help ensure that you choose the right one when purchasing a new device.
