The Most Important Device For Large Screen Splicing - Capture Card

The most important device for large screen splicing - capture card

At present, the multi-screen seamless splicing system on the market is mostly a large-screen projection splicing system using soft-edge fusion splicing technology, which can open multiple picture-in-pictures at any position on the screen, and the external computer can display the screen of the external computer on the screen. In the painting. Multi-screen seamless splicing separates a single VGA display signal into multiple signals, forming a multi-screen splicing of M*N to form a single logic screen.

Nowadays, one of the most important devices for realizing large-screen splicing system in the industry is the video capture card, because the large-screen projection splicing system can use different video capture cards to display external AV, VGA and other signals in the screen. In the painting, in order to meet a variety of VGA display devices can be displayed on the large screen, the computing power of the single large screen splicer itself cannot be satisfied, which requires the large screen splicer to receive a variety of signals and integrate the display output to On the big screen, the requirements for HD VGA capture cards are relatively high, such as 1920*1080, 2048*768, etc. That is to say, a VGA capture card is required, which not only can acquire high resolution, but also requires high speed and high frame count.
