4K30 UHD DVI (HDCP)ProScale演示矩阵切换器/双倍线器带切换特技

　　VP−772是一款8输入高性能UHD（4K）双倍线器，带各种过渡特技，可用于舞台租赁，现场直播等系统。它的接口为DVI−U输入（支持模拟，DVI和HDMI信号）和平衡立体声音频信号。该设备将选择的视频音频信号经过倍线处理之后输出到两个独立的DVI−I输出（主输出和预览输出），并带有平衡立体声音频输出。

　　PixPerfect™ Scaling Technology — Kramer’s extremely high performance, state–of–the–art scaling technology with extensive high–quality pull–down and de–interlacing algorithms, and full up–and down–scaling of the video inputs.

　　K–IIT XL™ Picture–in–Picture Image Insertion Technology — Ultra–stable picture–in–picture, picture–and–picture, and split screen capability. Any video source can be inserted into or positioned next to any other video source with full window positioning and sizing controls.

　　Seamless Video Switching — With cuts or built–in special effect transitions, including horizontal, vertical, diagonal circle and chessboard wipes, cross–fading, and more.

　　Dual Scalers — For “live” seamless transitions from one source to another with two independent outputs: a PREVIEW OUT and a PROGRAM OUT. The PREVIEW output, including an OSD menu for making adjustments, is used for determining how the scaled output looks before displaying live during a presentation.

　　8 Preview Input Buttons — For switching a selected input to the PREVIEW output and 8 PROGRAM input buttons for switching a selected input to the PROGRAM output.

　　Output Resolutions — Up to 4K30 UHD (3840x2160) for single output mode (non–dual scaler); HDTV and computer graphics resolutions with selectable refresh rates.

　　Multi–Format Operation — Selectable HDMI, VGA, YUV or CV on each DVI–U input and VGA or HDMI on each DVI–I output.

　　Audio–Follow–Video & Breakaway Options

　　Advanced De–interlacing Functions — Including 3D comb filtering, film mode, diagonal correction and motion detection.
