Kramer VP-794

The VP−794 is a high−performance switcher/scaler/edge−blend & warp for analog and digital video signals developed specifically for driving large screen displays and multiple screen applications from video or graphics sources. It up− or down−scales the incoming signal, processes the image with HQV and flexible warping, geometry correction and professional grade edge blending and outputs the signal to 3G HD−SDI, DVI/HDMI, VGA and S/PDIF connectors. VP−794 includes a special mode for driving LED video walls with pixel−accurate output image sizing.

• Optimized Operating Modes — For LED video walls, or soft edge–blend and warp for projection, or scan conversion/scaling for general purpose scaler/switcher use.
• Multi–Format Operation — 3G HD–SDI, HDMI, DVI, computer graphics, component, composite and s–Video inputs for signals up 1080p & WUXGA.
• Full Warp Mapping — Easy warp map creation for stacked projector alignment and curved screen multi–projector tiling via an included PC application.
• Powerful Geometry Correction — For off–axis projection, pin/barrel and image rotation, pan, tilt and zoom.
• Edge Blending — 4–sided professional grade edge blend with 48–bit processing, degamma & multi–region black level correction.
• HQV® Video Processing — HQV (Hollywood Quality Video) processing represents the state–of–the–art in video processing technology, with the highest quality de–interlacing (with 3:2 & 2:2 pull down), 4D motion adaptive SD noise reduction and outstanding scaling performance for both standard–definition and high–definition signals.
• HDTV Compatible.
• HDCP Compliant.
• Supported Resolutions — HD 720p, 1080i, 1080psf (psf digital only), 1080p23.97/24/25/30, 1080p30, 1080p50, 1080p59.94, 1080p60; ED 480p, 576p (not via SDI); SD 625i (576i), 525i (480i); common VESA graphics formats from 640x480 to 1920x1200 (with reduced blanking for 1920x1200 and 1600x1200 modes).
• LED Videowall Mode — Superb video down–scaling to as low as 128x96 pixels.
• Genlock (V–Lock) — Accepts bi–level, tri–level sync or black & burst.
• Selectable Lock Modes — Genlock (V–Lock), I/O lock or frame rate conversion.
• HDMI Support — Deep color up to 12 bit.
• Multi–Standard Support — For CVBS & YC in PAL, NTSC, SECAM formats with selectable 3D comb for composite.
• Superior De–interlacing — Motion adaptive per pixel video de–interlacing with multi–directional diagonal de–interlace filter reduces HD & SD image flicker and artifacts.
• Live Image Capture — Logo/still/backdrop capture with full scale warp/blend of the captured image, 4 memories.
• Selectable Processing Versus Latency — Best picture and low latency modes; latency as low as 0.25–frame progressive inputs, 1.25–field interlaced inputs.
• Selectable Aspect Ratio Conversion — Or incoming aspect ratio preserve mode.
• Built–in Time Base Corrector — Stabilizes unstable video sources.
• Flexible Color Calibration Controls — RGB Gains, RGB Cut–Off/Black Level, Saturation, Hue, Brightness, Contrast controls, Gamma selection with separate calibration memories per input channel.
• Audio De–embedding — From HDMI & 3G HS–SDI to S/PDIF compatible formats.
• Built–in Test Pattern Generator.
• USB Port — For upgrading firmware.
• Non–Volatile Memory — Auto–saves and recalls settings.
• Flexible Control Options — Front panel buttons, jog wheel and LCD menu display, RS–232, TCP/IP API and Web Server, PC–based Warp Map Generator tool.
• Setting Backup — Save complete system config to disk via Web browser interface to clone or restore units.
• Front Panel Lockout.
• Picture In Picture — In LED and scaler modes with flexible pixel–accurate PIP sizing.
• Worldwide Power Supply — 100–240V AC.
