USB, DVI, HDMI Connectors

Each type of connection technology has its own advantages and disadvantages when it comes to interfacing digital devices. The USB, DVI (Digital Video Interface) and HDMI (High-Definition Multimedia Interface) are three of the most popular and widely used connection technologies. While each type has its own main purpose and offer different advantages depending on the needs of the user, understanding their characteristics and properties is key to determining the best option for each connection.

USB

The Universal Serial Bus (USB) is a serial bus designed to carry data between computer and external devices. It enables connection of numerous devices through a single port, and all connected devices will be accorded equal privileges and the same data rate. USB ports are mainly used to connect digital cameras, printers, external storage, game controllers, and other external technology. Many computers have multiple USB ports and with the availability of USB hubs, can connect multiple inputs with just one connection.The USB interface can be seen as a physical layer consisting of a four-pin connector, two of which are called Data+ (the high-speed line) and Data– (the low-speed line). The other two pins are called Power+ and Power– for providing power. The USB also includes a communication facility, which includes commands, errors, and a data packet for transferring data through the respective pins.

DVI

Digital Visual Interface (DVI) is a digital interface for transmitting video signals from a source such as a desktop or laptop computer to a separate display source such as a monitor or projector. DVI is the successor to the analog VGA (Video Graphics Array) standard. DVI support digital and analog video signals as well as multi-channel audio signals. There are three different types of DVI connectors: DVI-A, DVI-D, and DVI-I.DVI-A is an analog-only connection and is rarely used today. DVI-D is an all-digital connection used to send digital video from the source to the display. DVI-I is an integrated connection that can be used to transmit both digital and analog video signals.The DVI connector consists of two components, the connector and the link that transmits the video. The connector is composed of 24 pins or 29 pins, depending on the type of DVI being used. The link consists of four lines: two clock pairs and two data pairs.

HDMI

HDMI (High-Definition Multimedia Interface) is an all-digital audio/video interface designed to transmit high-definition video and multi-channel audio data from a source such as a Blu-Ray or DVD player to a compatible display such as a television. HDMI uses the same cable connector as DVI, but has additional pins in order to support the larger bandwidth of the HDMI standard. The HDMI connector includes 19 pins that are used to transmit both audio and video data.The HDMI interface also provides support for two different data rates: single-link and dual-link. The single-link rate supports resolutions up to 1080p at a 1.65GHz frequency, while the dual-link mode supports resolutions up to 4K at a 3.4GHz frequency.

Application Field and Working Principles

USB is the most versatile of the three connections technologies and can be used for devices such as digital cameras, printers, external storage, game controllers, and other external technology that require a fast, reliable data connection. DVI is the preferred technology for connecting computers to displays since it can take advantage of higher resolutions than its analog predecessor, VGA. HDMI is the most complex of all the connection technologies, allowing for the transmission of both audio and video data at higher resolutions.No matter which technology is used, the principles remain the same. The output source needs to be connected to the input source so that data can be transmitted. Each of the three technologies use pins and the appropriate interface to ensure that data can be sent in a manner that is both reliable and secure.
