Product Specifications

2 in 1 Video processor HD-VP1220



HD-VP1220 is one powerful 2-in-1 controller which with twelve 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.

Video input interface—1 high-definition video input (HDMI), 1 digital video interface (DVI), 1 DP interface, 1 analog input (VGA), 1 extended EXT input interface (DVI or SDI, standard with DVI ).

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

Debug control interface-square USB port (Type B), Wi-Fi.

Dual screen layout—support dual screen 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 12 network port output-maximum load 7.8 million pixels, maximum width 16000, 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 Scenes

Simultaneously display video equipment such ascomputer/TV/camera.
