INTRODUCTION 1.1. General Introduction VP-794 is a very flexible image scalers developed specifically for driving large screen displays such as Projectors and LED videowalls in multiple screen applications from video or graphics sources. VP-794 features the ability to switch between two internal sets of firmware, one optimised for Projection soft edge blend and warp and the other optimised for LED walls.
System control is via a menu system either on screen or through the inbuilt TCP/IP Web server or via the built in LCD panel and jog dial. The OSD (On Screen Display) is scaled to fit the chosen window. Note: At extreme low pixel count resolutions the OSD is hardly readable and control from a Web browser or the inbuilt LCD is recommended. Additionally a free API manual is published on our Website to allow the use of the LAN or RS232 remote control ports. www.kramerelectronics.com . 1.2.
VP-794 SYSTEM DESCRIPTION 2.1.

3.1.3. Web Browser The factory default is DHCP. The Network Settings menu allows to configure the VP-794 TCP/IP address. Under Address Type a static or DHCP leased address can be chosen. The static address and Netmask needs to be entered manually. The Network Settings menu has a section with information on the DHCP Status and IP address assigned to the board, as well as the fixed MAC Address programmed into the VP-794.
3.4. Software Operation Once the address has been entered the Web browser starts to load pages from the VP-794 mirroring the menu system of the unit. All menu items are shown as their respective buttons, sliders and list boxes and can be accessed and altered with the PC mouse or corresponding navigational key presses. To control VP-794 through a network start a Web Browser and enter the TCP/IP address of the unit in the address field of the browser.
Menu items can be lists, sliders or alpha numeric fields. A list item can be activated by moving the mouse pointer over the list item and clicking the left mouse button. The list comes up and an item can be selected by moving the mouse pointer to the desired value (ON or OFF) and clicking the left mouse button again. A slider value can be changed by moving the mouse pointer over the slider, click and hold the left mouse button and move the mouse to the right or left to decrease or increase the value.
A page for file uploads is provided. Test patterns can be created on a PC and uploaded to the VP-794 unit. Also, an alpha map can be loaded to VP-794. Details are outlined in section 4. VP-794 set-ups can be backed up to a PC and restored later through Web browser uploads.
3.5. Introduction The front panel has keys and a jog wheel for OSD and local LCD menu navigation and direct keys for input channel selection. 1 2 3 4 5 6 When applying power to the unit it starts up. This is indicated by the green ON LED flashing. Once the unit is operational, the ON LED is permanently on. 1 – Standby key: By pressing the Standby Key, the unit is put into standby mode. This is indicated by the red Standby LED being permanently on.
The back panel features all input and output connectors, communication ports and the power supply connector.
3.6. Main Menu The main menu lists the input channel select item, 6 sub menus, and a menu item for automatic setup of VGA modes. The 6 sub menus are Output, Color, Geometry, Multiple Unit, Enhancement and System. On each menu page an Exit menu item is available to leave the menu or submenu. VP-794 also has a separate back key to leave a submenu. Some adjustments are not applicable to all signal types or operating modes, in which case those nonapplicable functions will be greyed out and are not accessible.
Set to LCD/Plasma if you want only scaler functions and do not need the warp functions to be shown in the menu system. In this mode also the Flicker Filter becomes available. 3.8.2. Output Mode Settings: 640x480, 800x600, 1024x768, 1280x768, 1280x800, 1280x1024, 1400x1050, 1600x1200, 1920x1200, 480i, 576i, 480p, 576p, 1080i, 720p, 1080p Set up the desired output resolution with output mode. The output mode setting should match the native resolution of the imaging device to avoid double scaling.
For all other modes 48Hz, 50Hz and 60Hz refresh rate is available. 3.8.5. I/O Lock Available settings: Off, Source, Genlock, Auto If I/O Lock is switched OFF the output is run with a fixed refresh rate determined by the frame rate setting. This setting will result in the output vertical refresh rate deviating from the input refresh rate, even if both are nominally at the same rate. This causes occasional frame dropping or repeat.
It is recommended to use a setting between 0 and 16 and not more than 20. For most LED videowalls the optimum setting for Black Crush is between 8 and 20. For particularly noisy subject material 24 can be used but detail loss may occur in dark areas. If too high a setting is chosen, image solarization may be observed where dark image areas turn completely black or even change color. 3.8.9. Output Config This Menu provides items to configure the output port.
3.9. Color This is an INPUT channel menu containing adjustments associated with setting up inputs to the unit. 3.9.1. Black-Level Offset Settings: 0 IRE, 7.5 IRE Used to select 7.5 IRE black level set-up adjustment. Should always be set to 7.5 IRE for HDMI video and NTSC video inputs and should usually be OFF for PAL analog video inputs. 3.9.2. Black-Level Settings: -50 to 50 in steps of 1 Black level controls the offset applied to the video signal. (same as the brightness control on a TV) 3.9.3.
3.10. Geometry This menu contains adjustments associated with setting up position, aspect ratio and scale of the input signal.. 3.10.1. Horizontal and Vertical Position Settings: in steps of 1 pixel or line Change the positional values to match the display boarders. 3.10.2. Edge Control Submenu for changing the position of the image edges, effectively scaling the image in horizontal and vertical direction. 3.10.3. Warp Note:- This menu is only available when Display Type is chosen as Projector.
3.10.4. Picture Format Settings: Standard, Full Screen, Crop, Anamorphic Picture Format allows a user to select the displayed aspect ratio where the signal input is different to the display panel’s natural aspect ratio. Note that some aspect ratios may not be applicable to all signal types, in which case selecting a nonapplicable aspect ratio conversion will have no effect on the displayed image. When a 16:9 image is displayed on a 16:9 panel all settings give an identical full screen image.
3.11. PiP VP-794 can be rebooted in a single unit configuration in the System Menu. Then the multiple unit menu is replaced by a PiP menu. It contains adjustments associated with setting up source, position and size of a picture in picture video image. 3.11.1. PiP Input Selects the video source for the PiP window. The available PiP video sources depend on the currently displayed (main) video source.
3.12. Multiple Unit VP-794 when operated it’s Projector or LED modes and in the default ‘multiple unit’ configuration (not PIP) it has a Multiple Unit menu. This is to set up each unit for use in a multi screen application. Multiple screens are stitched together to provide a bigger display with higher resolution than a single display. Each display is driven by a separate VP-794 unit. In a multi projection display the individual projections typically are chosen to overlap to give seamless transitions.
3.12.3. Horizontal Pos and Vertical Pos Settings: 0 to 3 indicating co-ordinates 0,0, to 3.3 for the maximum matrix size of 16 With Auto zoom turned ON this provides the VP-794 unit information of which window portion of the total image it is assigned to and has to process (cut out and resize). Note:- This function can be used in conjunction with the item above to select the blend regions to be provided even when auto zoom is turned off 3.12.4.
3.12.6. Black-Level Uplift In LED mode: This should be set to zero In Projection mode: This enables the user to provide a black level uplift to compensate for the additional light leakage from multiple projectors in overlap regions. The black level uplift can be set for the 9 possible regions of the image. Setting the black level uplift for the middle of an edge also sets the black level uplift for the two adjacent corners, and if needed the corners can then be set individually.
3.13.4. Flicker Filter Note: This feature and the corresponding sliders are only available when VP-794 is operated in LED or LCD and Plasma mode to be set under Output/Display Type/Display. Also, this feature is only available when the Display Mode is set to Low Latency. In low latency mode the motion adaptive de-interlacer is switched OFF and the Flicker Filter is used to achieve a decent image quality.
For 3GSDI you can choose between LevelA and Level B type input modes. SDI audio input is routed to the HDMI and 3GSDI output connector by default. VP-794 can also be set to monitor audio on the SPDIF connector. SDI Audio on the HDMI and 3GSDI connector and SPDIF connector are mutually exclusive. Two consecutive SDI audio channels can be output on the HDMI and 3GSDI output interface. The group can be chosen. Or all eight SDI audio channels can be transmitted.
3.14.5. Menu Settings This menu provides items to change the menu position and menu display time, i.e. the time after which the OSD is switched OFF again with no user interaction. OSD Messages can be activated and deactivated. The menu language can be altered and the keypad can be locked. To unlock the keypad a combination of keys has to be pressed at the same time. The locking of the keyboard is accompanied by the message that the keypad is locked and which keys need pressing to unlock the unit.
REMOTE CONTROL WEB SERVER 4.1. Introduction VP-794 features a Web server which connects to a PC Web browser via TCP/IP. The menu system of VP-794 is mirrored into the Web browser and all menu items can be accessed and controlled through the keyboard or mouse of the PC. 4.2. Installing the Software No extra software needs to be installed on a PC. The PC Web browser is used as the graphical user interface for all control items.
4.5. File Upload A page for file uploads is provided. Test patterns can be created and stored on the PC. Four such custom test patterns can be uploaded to and stored by the VP-794 unit. Each of the test patterns in the four slots can be deleted and replaced by another test pattern. The test patterns need to be in RGB 24bit .PNG format as supported by MS Paint®.
