USB

USB (Universal Serial Bus) is now the de facto standard for connecting peripherals to computers. The USB family of connectors includes Type-A, Type-B, micro USB, mini-USB and more. USB Type-A and Type-B connectors and cables are typically used to connect computers to peripherals such as printers, scanners, keyboards, mouse, and more. USB offers a host of advantages over other types of connectivity options. These include the ability to daisy chain, plug-and-play compatibility, reduced cable clutter, and more.

USB Application Field and Working Principle

USB is an industry standard developed to connect computers and peripherals. It provides a series of connections from the host computer to various peripheral devices such as keyboards, mice, printers, and digital cameras. USB has been designed to be hot-swappable, meaning devices can be connected and removed when the system is running. It allows you to connect multiple peripheral devices such as keyboards, mice, scanners, and external storage devices without the need for additional power or control sources.

USB cables are used to provide data connections from your PC or laptop to a peripheral device. When connected, the USB signals are interpreted by the host controller. The host controller then attempts to configure the device, and when successful, makes the necessary connections to enable data transfer. Data is then communicated between the computer and the peripheral devices using the USB ports. Different types of USB cables are used for different operating systems.

USB has been widely adopted by virtually all computer manufacturers and peripherals developers as the standard connection interface. The use of USB has allowed for the development of a wide range of computer peripherals such as external hard drives, digital cameras, printers, scanners, and more. As the demand for smaller and faster data transfer rates increases, new versions of the USB standard have been developed, such as USB 2.0 and USB 3.0.

DVI

DVI (Digital Visual Interface) is a digital interface that is used to transmit video data. The interface was developed by the Digital Display Working Group (DDWG) and first released in April 1999. It is commonly used to connect computers to displays such as television sets or computer monitors. DVI supports both analog and digital displays. The interface is backwards-compatible with the VGA interface, allowing users to use existing VGA cables to connect DVI-enabled equipment. DVI comes in different varieties, including DVI-A, DVI-D, DVI-I, DVI-M, and more.

DVI Application Field and Working Principle

DVI is commonly used to connect computers to digital displays such as television sets or computer monitors. It can support both analog and digital displays and is also backward-compatible with the VGA (Video Graphics Array) interface. A DVI cable can be used to connect a computer to an analog display, but an adapter will be required to convert the signal.DVI transmits uncompressed digital video signals from the computer to the connected display. It is capable of displaying resolutions up to 1920×1200, with some devices being able to support resolutions up to 2560×1600. The video data is transmitted over a 24-pin or 29-pin connection, depending on the type of DVI connector used. This connection includes three rows of contacts, labeled TMDS (Transition Minimized Differential Signaling), which are used to transmit the video data from the computer to the display.

In addition, the DVI interface can also be used for audio transmission, as it supports the two uncompressed audio streams commonly found in the HDMI (High Definition Multimedia Interface). To enable audio transmission through the DVI cable, you will need to use a specialized adapter.The DVI interface is widely used in the computer industry and is available on most modern desktop and laptop computers. The majority of LCD monitors and televisions, as well as most high-definition content sources, are also equipped with the DVI interface.

HDMI

HDMI (High Definition Multimedia Interface) is an interface that was developed by the HDMI Forum to provide a high-definition digital audio and video connection between devices such as televisions and computers. It is the latest in a series of standards developed by the HDMI Forum. HDMI was the first interface to combine high-definition video and multi-channel audio into a single interface, and is now the standard digital connection for many consumer electronics devices such as televisions, DVD players, and game consoles.

HDMI Application Field and Working Principle

HDMI is a digital interface that is used to transmit audio and video signals from devices such as Blu-ray players, DVD players, computers, and game consoles to displays such as HDTVs and projectors. It is capable of transmitting uncompressed digital video and audio in high-definition (HD) and ultra-high-definition (UHD) resolutions. The HDMI interface is capable of carrying signals with resolutions up to 4K (3840x2160), and some HDMI cables are capable of carrying signals with resolutions up to 8K (7680x4320).

HDMI cables come in different varieties, including standard cables, high-speed cables, and ultra-high-speed cables. Standard HDMI cables are capable of carrying signals with resolutions up to 1080p (1920x1080), while high-speed and ultra-high-speed HDMI cables are capable of carrying signals with resolutions up to 4K (3840x2160) and 8K (7680x4320) respectively.

The HDMI interface supports multiple audio formats, including uncompressed and compressed audio formats. It is also capable of transferring other audio/video-related data such as consumer electronic control (CEC) data and One-Touch Play technology. This allows devices to be connected to each other and for data to be exchanged between them.
