Videovõimendi

Videovõimendi, also known as a video amplifier or distribution amplifier, is an electronic device used to boost and distribute a video signal. Its primary function is to take an incoming video signal and output multiple identical copies, each with sufficient signal strength to maintain its quality over a given distance. This is particularly useful in applications where a single video source needs to be displayed on multiple screens simultaneously, such as in video conferencing, digital signage, home theater systems, or professional video production environments.

The videovõimendi ensures that the video signal is not degraded by signal loss that would occur if the source were directly connected to multiple displays. Signal degradation can manifest as a weaker or "washed out" image, loss of color fidelity, or even complete signal dropout. By amplifying the signal, the videovõimendi compensates for this loss, ensuring that all connected displays receive a clear and robust video feed.

These devices come in various forms, from simple, compact units for home use to more complex rack-mountable solutions for professional installations. They support a range of video formats, including analog (like composite and component video) and digital (like HDMI and SDI). The number of output ports can vary, allowing for distribution to a few displays or many. When selecting a videovõimendi, factors such as supported video resolutions, bandwidth, and the number of outputs required are important considerations.
