Description

I. Product Overview
The **Digital SDI Signal Distributor**, independently developed by Shenzhen Huashi Digital Technology Co., Ltd., is an industrial-grade device designed for efficient sharing of high-definition and standard-definition video signals. This device can accurately distribute any single high-definition/standard-definition 3G/12G SDI serial digital video signal to multiple output ports in a **lossless, delay-free, and high-fidelity** manner, synchronously outputting to multiple high-definition TVs, projectors, or large-screen display devices. It is ideal for multi-user collaborative viewing scenarios such as command centers, studios, monitoring halls, and exhibition displays, perfectly addressing the need for synchronized signal sharing across multiple terminals. The distributor ensures that all terminal displays receive visuals identical to the source signal—**without delay, attenuation, or distortion**.
