Huidu HD-VP820 Video Processor Overview

HD-VP820 is one powerful 2-in-1 controller which with eight network ports output, support dual live video windows integrated video processing and sending card functions.

It product supports 4K input and is a cost-effective video processor for mid-to-high-end video control equipment in the LED large-screen display, performance and rental, studio and other markets.

Practical video input interface —1 HD video input interface (HDMI), 1 digital video input interface (DVI), 1 analog input interface (VGA),1 * extended EXT input interface (DVI or SDI, factory standard DVI)。

Audio input and output HDMI/DP audio input ,1 independent analog audio input, select 1 from 3 to send to the audio output terminal.

Debug control interface—Square USB(Type B)、Wi-Fi。

Dual-screen layout—Support dual images function,picture-in-picture PIP, picture-outside-picture POP.

Input resolution adjustment—In DVI/HDMI/DP input mode, it supports preset and custom adjustment of common input resolutions.

Support 8network port output—maximum load 5.2 million pixels, maximum width 8000, maximum 3840.

Set-and-save —The set-and-save technology solves the user’s cumbersome setting and manual storage process, the user no need to manually save after adjusting or adjusting the parameters, and the user parameters are automatically stored in EEPROM, even if the power is turned off After the power failure, the parameters before the power failure remain in the device.Save template function—it can save the current settings, up to 8 groups of template parameters, and save the parameters to the corresponding mode, which is convenient for customers to call directly.Key lock — lock the keys to prevent accidentally pressing the operation keys to change settings during operation.。

Application Scenario

Displaying the screen of a video playback device such as a computer/TV/camera synchronously
