1 Introduction Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world of unique, creative, and affordable solutions to the vast range of problems that confront the video, audio, presentation, and broadcasting professional on a daily basis.
2 Getting Started We recommend that you: Unpack the equipment carefully and save the original box and packaging materials for possible future shipment Review the contents of this user manual i 2.1 Go to http://www.kramerelectronics.com/support/product_downloads.asp to check for up-to-date user manuals, application programs, and to check if firmware upgrades are available (where appropriate).
2.3 Recycling Kramer Products The Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC aims to reduce the amount of WEEE sent for disposal to landfill or incineration by requiring it to be collected and recycled. To comply with the WEEE Directive, Kramer Electronics has made arrangements with the European Advanced Recycling Network (EARN) and will cover any costs of treatment, recycling and recovery of waste Kramer Electronics branded equipment on arrival at the EARN facility.
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.
K-Storm™ Scaling Technology - Kramer’s extremely high performance scaling technology.
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/IRR50). The external IR receiver can be located up to 15 meters away from the machine.

4 Installing in a Rack This section provides instructions for rack mounting the unit.
5 Connecting the VP-790 ! i Always switch off the power to each device before connecting it to your VP-790. After connecting your VP-790, connect its power and then switch on the power to each device. You do not have to connect all the inputs and outputs, connect only those that are required. To connect the VP-790, as illustrated in the example in Figure 3, do the following: 1. Connect an SDI source (for example, an SDI digital camera) to the SDI IN BNC connector. 2.
10. Connect the SDI OUT BNC connector to an SDI acceptor (for example, a projector). 11. Connect the DVD-D/HDMI VIDEO OUT connector to an HDMI acceptor (for example, an LCD display). 12. Connect the PC OUT 15-pin HD connector to a VGA acceptor (for example, a display). 13. Connect the audio output signal to the S/PDIF OUT digital audio acceptor, as required (not shown in Figure 3). 14. Connect the power cord (not shown in Figure 3).
6 Configuring the VP-790 via the OSD MENU Screens The VP-790 uses an on-screen display (OSD) menu for system configuration. The menu appears as an overlay over any images that are output from the VP-790. There are seven sub-menus (the PIP and Multiunit menus automatically replace each other in the Single Unit mode and the Multi-unit mode, respectively) that are used to configure the VP-790. You can activate and navigate these menus from the front panel buttons or from the IR remote control.
To return to the previous menu level, press the front panel MENU button or the MENU key on the remote control. All settings and adjustments are automatically saved in non-volatile memory for each of the inputs (except USB). i 6.1 The values defined in the different menus may change according to the firmware version (you can download the up-to-date firmware version from our Web site at http://www.kramerelectronics.com).
Setting Component Sync Function Select the component sync: 3 Wire, 4 Wire, Auto 3 Wire: The sync signal is stripped from the green or Y channel (typical for YUV) 4 Wire: The sync signal is derived from a separate sync line (typical for RGB) Auto: Automatically detects a sync signal The Auto setting will automatically detect a sync signal and set-up the VP-790 accordingly SDI to HDMI Audio Select the channels through which the SDI audio signal will be routed to Map the HDMI output: Stereo ch(1,2), Stereo c
6.2 The Picture Screen The Brightness, Contrast, Color, Hue and sharpness settings are saved individually for each input (except USB).
6.
Setting Aspect Ratio Function Set the aspect ratio to: Standard, Full Screen, Crop or Anamorphic (also see Section 6.3.1): Standard: Maintains the aspect ratio of the input and scales the image to fit the display size.
The Flicker Filter reduces interlace horizontal line edge bounce or flicker when scan converting from a computer progressive input format to an interlaced output signal. By choosing the filter strength and recursion mode it is possible to choose between higher levels of flicker reduction or better motion reproduction. 6.3.2 Selecting the Correct Aspect Ratio You can configure the aspect ratio of any output image to fit your application.
6.
6.4.1 The PIP Feature The VP-790 PIP feature lets you show two images on one screen: the main window and the PIP window.
6.4.1.1 Activating the PIP You can the PIP feature (indicated by an illuminated PIP front panel button) in any of the following ways: Press and hold (for about 2 seconds) the front panel PIP button Press the PIP button on the IR remote control transmitter (see Section 7.4) Access the OSD menu, select SETUP>Operation Mode>PIP/Single Mode and then in the PIP menu select the PIP type Via the Web pages (see Section 7.3.3) 6.4.1.
Figure 9: Audio Screen Setting Auto Zoom Function Select to automatically crop and zoom the input video image so it outputs the appropriate part in the matrix Units Wide Set the number of screens comprising the width of the wall display matrix (1 to 4) Units High Set the number of screens comprising the height of the wall display matrix (1 to 4) H-Position Define the horizontal position of the display in the matrix The unit will cut and resize the output signal according to the display’s location in
Setting Blend Width (Contd.) i Function Each display in the matrix needs to be set to the same blend width and offset value for its left and right sides. The top and bottom blend width and offset values also need to be identical (though they don’t have to be identical to the left and right settings). This is necessary for the calculating the Auto Zoom for the matrix.
6.6 The Geometry Screen Figure 10: Geometry Screen 24 Setting Application Function Default Select the output application: Off, Keystone, Anyplace, Rotation or PC Location Select the location of the display: Front Tabletop, Front Ceiling, Rear Tabletop or Rear ceiling Horizontal Keystone Adjust the horizontal keystone If the projector is located at an angle to the left or right of the screen Vertical Keystone Adjust the vertical keystone.
The settings available for each application are defined in the following table: 6.
Setting Frame Lock Function Set the frame lock mode: Off, Source, Genlock or Auto Off: the output is set to a fixed refresh rate defined by the frame rate setting (in the Output menu, Section 6.3), which deviates from the input refresh rate, even if both are nominally at the same rate.
