Videoliitäntä

A videoliitäntä, or video interface, refers to the physical connection and signaling protocol used to transmit video signals between electronic devices. This allows for the display of images and video content generated by one device, such as a computer, game console, or media player, on another device, typically a monitor or television.

Over time, various types of videoliitäntä have been developed, each offering different resolutions, refresh rates, and features. Early interfaces included analog connections like VGA (Video Graphics Array) and S-Video, which were common for CRT monitors and older televisions. These interfaces transmit analog video signals.

With the advent of digital technology, digital video interfaces have become prevalent. HDMI (High-Definition Multimedia Interface) is currently the most widely used standard, supporting high-definition and ultra-high-definition video, as well as multi-channel audio and other data. DisplayPort is another significant digital interface, often found in computer displays and graphics cards, known for its high bandwidth and support for multiple monitors from a single port. USB-C, while a versatile connector, can also carry video signals through protocols like DisplayPort Alternate Mode, enabling a single cable to handle video, data, and power.

The choice of videoliitäntä depends on the devices being connected, the desired video quality, and the specific features required. Compatibility between the ports on both the source and display devices is essential for a functional video connection. Advancements continue to be made in video interface technology, aiming for higher bandwidth, lower latency, and more integrated functionality.
