INTRODUCTION 1.1. General Introduction VP-791 is a very flexible image scaler developed specifically for driving large screen displays from SDSDI, HD-SDI and 3G-SDI serial digital source. VP-791 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-791 SYSTEM DESCRIPTION 2.1. Product Overview VP-791 is designed to accept the input signals: 3GSDI and HDSDI and SDI (Serial Digital Interface) via BNC 2.2. Product Specification This section provides technical details of the VP-791 input and output connections. 2.2.1. Power Supply Requirement 12V DC table top power supply requiring a 100V-264VAC 50 and 60Hz mains connection. 2.2.2.
VP-791 CONTROL 3.1.
3.2. Introduction The VP-791 units have the input connector on one side of the housing and the output connector as well as the communication ports on the opposite side. The keypad for controlling VP-791 is located on the input connectors side. 8 1 7 6 2 5 4 1 – Keypad with three keys for OSD menu navigation (Menu, Down and Up). With the Menu key the OSD menu is activated. The up and down keys are used for OSD menu navigation.
2 – 3G-SDI input 3– 4 – DVI-I output connector (only the digital DVI-D is supported, HDMI receivers can be connected with a DVI/HDMI adapter cable) 5 – TCP/IP port 6 – USB port 7 – RS232 port 8 – Power supply connector
3.3. Main Menu The main menu lists 5 sub menus. The 5 sub menus are Output, Color, Geometry, Enhancement and System. On each menu page an Exit menu item is available. Some adjustments are not applicable to all signal types or operating modes, in which case those non-applicable functions will be ghosted and are not accessible via the menus. All menus have a top status line and a bottom line indicating the firmware revision number.
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 1.1/1.2 devices it is 24 bit, for HDMI 1.3 compliant devices it is up to 36 bit. DVI forced will output with 24 bit color depth irrespective of the supported standard of the attached monitor.
3.5.6. (Available) Frame Rates Settings: 60 and 50 Hz, 60, 50 and 24 Hz, 60, 50 and 48, 60, 50, 24 and 48 Limits the possible output frame rates that can be selected. It is primarily to be able to limit the choices available for the Auto refresh rate configuration. 3.5.5. I/O Lock Settings: ON, OFF If I/O Lock is switched off the output is run with a fixed refresh rate determined by the frame rate setting, which deviates from the input refresh rate, even if both are nominally at the same 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 Settings: 0 IRE, 7.5 IRE Used to select 7.5 IRE black level set-up adjustment. 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. Contrast Settings: -50 to 50 in steps of 1 Contrast controls the gain applied to the video signal. 3.6.4.
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.
3.7.5. Overscan Settings: 0 to 10 in steps of 1 Overscan is used to slightly zoom into the image. Thus, the border area of an image is no longer displayed on the screen. This cuts off unwanted features at the top or bottom from e.g. video images. 3.7.6. Pan Tilt Zoom This menu provided settings to zoom and shrink the image, as well as panning within the image. Pan Tilt Zoom (PTZ) can be switched ON or OFF. PTZ mode increases the latency of the system by one frame.
3.8. Enhancement The enhancement menu provide image enhancement functions. Note that the enhancement settings apply to video input signals only, not computer graphics signals. 3.8.1. Sharpness 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 Settings: USER 1, 2, 3, 4 A predefined setting stored under a user name can be selected. Several settings of the VP-791 can be stored under a user name. Thus, different users can store their preferred VP-791 settings and recall these profiles by picking up their user name from this menu.
3.9.6. Network Settings The Network Settings menu allows to configure the VP-791 TCP/IP address. Address Type: select a static or DHCP leased address. The static address and Netmask need 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-791.
REMOTE CONTROL WEB SERVER 4.1. Introduction VP-791 features a Web server which connects to a PC Web browser via TCP/IP. The menu system of VP-791 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.
FIRMWARE UPDATE 5.1. Introduction VP-791 has an USB port which allows a PC connection. With the Kramer PC Updater tool new firmware can be installed on VP-791 for feature upgrades and bug fixes. 5.2. Updating Firmware VP-791 accepts firmware downloads in a dedicated Updater mode. The unit is put in Updater mode by keeping the Menu key pressed at power up. If the Menu key is released within 10 seconds after power up VP-791 is in Updater mode. Otherwise, VP-791 is started normally.
