VP-790 - Overview
3 Overview
The VP-790 is a proscale genlock presentation scaler/switcher with edge blending,
warping and genlocking. The unit includes a powerful software tool to generate
custom warp maps to fit any projection surface.
The unit takes one of the input signals (RGB component, computer graphics,
composite, s-Video, HDMI, DVI or 3G HD-SDI), scales the video, embeds the audio
and outputs the signal to the computer graphics, DVI/HDMI and 3G-SDI outputs
simultaneously.
The VP-790 features:
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 and 2:2 pull down), noise reduction,
and scaling performance for both standard-definition and high-definition
signals
Flexible warp mapping for curved screen projection, simulation and 3D
alignment
Edge Blending –facilitates building large images using multiple projectors by
feathering the overlapped edges
A maximum data rate of 3Gbps
3G-SDI, HDMI, DVI, VGA Analog, Component YPbPr, RGsB/RGBS,
Composite and s-Video inputs with signal compatibility up to 1080p and
WUXGA
HDTV Compatibility
Genlock Input - ideal for use in broadcast video applications
HDCP Compliance. The HDCP (High Definition Content Protection) license
agreement allows copy-protected data on the HDMI input to pass only to the
HDMI output.
Three output connectors are provided which can be used simultaneously,
provided that the input signal is not HDCP encrypted. When the input signal
has HDCP encryption, the DVI-D output connector will carry a similarly HDCP
encrypted signal and the VGA and 3G-SDI connector will be disabled

VP-790 – Overview

K-Storm™ Scaling Technology - Kramer’s extremely high performance scaling
technology. High quality 3:2 and 2:2 pull down de-interlacing and full up and
down scaling of computer graphics video input signals
4D Motion, Noise Adaptive HQV noise reduction for spatial and temporal noise
Genlock and frame lock options, making the unit ideal for broadcast
applications
DVI/HDMI, 3G HD-SDI and computer graphics video (15-pin HD) scaled
outputs
DVI/HDMI supports HDMI with 36-bit video and multi-channel audio (DTS6.1, Dolby5.1
and PCM Multichannel (8x) at 48kHz)
SD-SDI, HD-SDI and 3G-SDI that support SMPTE 259M, SMPTE 292M and
SMPTE 424M compliancy
Standard Definition (SD-SDI) means an NTSC or PAL compatible video format,
consisting of 480 (for NTSC) or 576 (for PAL) lines of interlaced video
High Definition (HD-SDI) means a video format, consisting of 720 active lines of
progressive video or 1080 lines of progressive or interlaced video
3G-SDI means a video format, consisting of 1080 lines of progressive video
An S/PDIF audio output, de-embedded from HDMI
Multiple aspect ratio selections: standard, full screen, crop and anamorphic
4-field full resolution SD and HD processing
A USB port for in-field firmware updates
Built-in ProcAmp - Color, hue, sharpness, noise, contrast, and brightness
Front panel buttons, including menu, test pattern, PIP and Reset to XGA/720p
buttons
Scales and zooms (to up to 400% of the original size)
Non-volatile memory that retains the last settings used
Front panel lockout, as well as input lock and save lock features via the OSD
Control your VP-790 directly via the front panel push buttons, or:
By RS-232 serial commands transmitted by a touch screen system, PC, or
other serial controller
Remotely, from the infrared remote control transmitter (with on-screen menus)
Via the Ethernet

VP-790 - Overview
The VP-790 is housed in a 19” 1U rack mountable enclosure, with rack “ears”
included and is fed from a 100-240 VAC universal switching power supply.
3.1 Using the IR Transmitter
You can use the IR transmitter to control the machine via the built-in IR receiver on
the front panel or, instead, via an optional external IR receiver (Model: C-A35M/IRR-
50). The external IR receiver can be located up to 15 meters away from the
machine. This distance can be extended to up to 60 meters when used with three
extension cables (Model: C-A35M/A35F-50).
Before using the external IR receiver, be sure to arrange for your Kramer dealer to
insert the internal IR connection cable (P/N: 505-70434010-S) with the 3.5mm
connector that fits into the REMOTE IR opening on the rear panel. Connect the
external IR receiver to the REMOTE IR 3.5mm connector.

1. Connect an SDI source (for example, an SDI digital camera) to the SDI IN
BNC connector.
2. Connect an s-Video source (for example, an s-Video player) to the Y/C IN
4-pin VIDEO INPUT connector.
3. Connect a component video source (for example, a component video player)
to the COMP/RGB IN PR, PBand Y, RCA connectors.
4. Connect an HDMI source (for example, a DVD player) to the HDMI IN
connector.
5. Connect a computer graphics source to the PC IN 15-pin HD VIDEO INPUT
connector.
6. Connect a DVI source (for example, a computer) to the DVI-D IN DVI
connector.
7. Connect a composite video source (for example, a composite video player)
to the CV 1 IN BNC connector.
8. Connect a composite video source (for example, a composite video player)
to the CV 2 IN RCA connector (not shown in Figure 3).
