INTRODUCTION 1.1. General Introduction VP-792 is a very flexible image scaler developed specifically for driving large screen displays and multiple screen applications from video or graphics sources. VP-792 features a state of the art digital image processor which provides market leading HD& SD perpixel multiple Iow-angle motion-adaptive de-interlacing and automatic film pull-down correction for 3:2 and 2:2, significantly outperforming the capabilities of benchmark competitor products.

VP-792 SYSTEM DESCRIPTION 2.1. Product Overview VP-792 is designed to accept the following input signals: YPbPr or RGBS SD and ED and HD component video via 3 or 4 BNC connectors VGA analog (computer interface) via 15HDD DVI (Digital Visual Interface) via DVI-I (only the digital part is implemented on this connector), HDMI is supported via a HDMI/DVI adapter. 2.2. Product Specification This section provides technical details for all possible inputs.
2.2.5. Display Output A DVI-I connector is provided which will support DVI outputs as well as HDMI 1.3 with 36-bit video and HD audio formats when connected to a suitable HDMI 1.3 receiver. When the input signal has HDCP encryption, the DVI-D output connector will carry a similarly HDCP encrypted signal. When an HDCP encrypted signal is input, but the display device does not support HDCP, the output image will turn black and a message indicating HDCP Signal will come up to indicate this.
VP-792 CONTROL 3.1.
3.2. Introduction The VP-792 units have the input connectors on one side of the housing and the output connector and communication ports on the opposite side. The keypad for controlling VP-792 is located on the input connectors side. The active input is indicated by their corresponding triangles lit green. 1 8 7 2 6 5 3 4 1 – Keypad with three keys for OSD menu navigation (Menu, Down and Up) and a key for input channel selection (Input). With the Menu key the OSD menu is activated.
A factory reset can also be applied when pressing the factory reset key combination at power up. The keys have to be kept pressed for about 10 seconds until the RGB(S) input LEDs stop flashing. If the keys are released during that 10 seconds period the system will get into Updater mode (see section 5) since the Menu key is part of this key combination.
3.3. 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, Enhancement, System and Multiple Unit (only VP-792 and VP-792). On each menu page an Exit menu item is available. The menus are contextual, therefore some adjustments are not applicable to all signal types or operating modes, in which case those non-applicable functions will be ghosted or greyed out and are not accessible.
3.5.2. Location Settings: Front Tabletop, Front Ceiling, Rear Tabletop, Rear Ceiling The image can be flipped to accommodate different projection scenarios as well as screens mounted upside down. 3.5.3. Optimize for Display Settings: DVI forced, Optimized, DVI/HDMI Internally, the display interface processes data at a full ten bits per color. The color depth on the DVI-D output is determined by the supported standard of the attached monitor or device when set to DVI/HDMI. For DVI 1.0 and HDMI 1.1/1.
Otherwise it is displayed at 50Hz. A 25Hz input mode is output at twice the frame rate 50Hz. An exception to the 24 and 25Hz input mode treatment is if the output resolution is set to 480i or 480p. 480i and 480p are always run at 60Hz output rate. 50Hz input modes are displayed at 50Hz output rate. The output frame rate can also manually set to 24Hz, 48Hz, 50Hz or 60Hz Only 720p and 1080p output modes are available with 24Hz refresh rate. 480i and 480p output modes are only available at 60Hz refresh rate.
3.6. Color This menu contains adjustments associated with setting up inputs to the unit. Use the Up and Down keys to scroll to the required item and press the Menu key. 3.6.1. Black-Level Offset Available 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 inputs. 3.6.2. Black-Level Settings: -50 to 50 in steps of 1 Black level controls the offset applied to the video signal. 3.6.3.
3.7. Geometry This menu contains adjustments associated with setting up position, aspect ratio and scale of the input signal. Scale can be as simple as an overscan up to arbitrarily warping the image. 3.7.1. Horizontal and Vertical Position Settings: in steps of 1 pixel and line Change the positional values to match the display boarders. 3.7.2. Edge Control Submenu for changing the position of the image edges, effectively scaling the image in horizontal and vertical direction. 3.7.3.
Crop preserves the aspect ratio and scales the image to fit the screen. Dependant on the aspect ratio of the panel either the top and bottom or right and left areas of the image are cropped. Anamorphic scales the input image such that it is displayed with a 16:9 aspect ratio when displayed on the screen. The image is further scaled to fit into the size of the panel. Dependant on the aspect ratio of the panel the image is then either bordered by the right and left side or bottom and top of the panel.
3.8. Enhancement The enhancement menu provides image enhancement functions. Note that the enhancement settings apply to video input signals only, not computer graphics signals. 3.8.1. Sharpness Available settings: -50 to 50 in steps of 1 Control of the sharpening enhancement filters' levels. These are peaking filters to improve highfrequency response. Note that setting this control too high on a signal which already has good high frequency response will cause ringing or ghosting. 3.8.2.
3.9. System This selection contains functions which are more applicable to system operation than to picture adjustment. 3.9.1. User Available settings: USER 1, 2, 3, 4 A predefined setting stored under a user name can be selected. Several settings of the VP-792 can be stored under a user name. Thus, different users can store their preferred VP-792 settings and recall these profiles by picking up their user name from this menu.
Custom test patterns loaded into the file system of the unit through the Web interface, can be accessed through the same means. The speed of the moving cross test pattern can be changed. Also, the foreground and background color and the line width of the moving cross test pattern can be changed in this menu. Note: Most test patterns are scaled in multiple unit configurations with Autozoom enabled since they are useful for setting up the blend and warp of the system.
In the Network Settings menu is a submenu Status Announce Setting. This feature is activated when Enable Status Announce is switched on. VP-792 will then send messages out continuously through RS232 and TCP/IP to signal system condition. Server address and port of the PC where to send the message need to be entered. The Refresh Rate determines the rate at which the VP-792 status condition and the message entered under Custom Data being sent out. 3.9.8.
3.10. Multiple Unit The VP-792 has a Multiple Unit menu 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-792 unit. When using the Auto Zoom function - Each VP-792 unit gets the same graphics or video input signal through a distribution amplifier. The VP-792 unit cuts out and resizes the image to display the part of the image assigned to the corresponding screen.
Note: Each VP-792 unit needs to be provided with the exact same value for left and right blend region. Top and bottom blend region have to be identical as well, but don´t need to have the same value as left and right. The VP-792 units do not communicate between each other and thus they have to make an assumption for auto zoom calculations and that is overlap of the neighbouring (and those beyond) projectors is identical. 3.10.5.
REMOTE CONTROL WEB SERVER 4.1. Introduction VP-792 features a Web server which connects to a PC Web browser via TCP/IP. The menu system of VP-792 is mirrored into the Web browser and all menu items can be accessed and controlled through the keyboard or mouse of the PC. Note: Backup and Restore is only available for V2 hardware. 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.
4.4. Software Operation Once the address has been entered the Web browser starts to load pages from the VP-792 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.
