Kramer Electronics VP-794 8-Input Universal Live Event Scaler/Switcher
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. 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. 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. Picture In Picture In LED and scaler modes with flexible pixel-accurate PIP sizing. Worldwide Power Supply 100-240V AC.
