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.

VP−794 features include:

  • 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).

  • 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 Colour 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.
