Converting 802 Images for use on 881/882



If you have made images for the 802 series of video generators, you can easily convert them to XML files for use on the 881 or 882 generators.

Here’s the procedure for converting 802 images (.IMG) to 880 images (.XML):
  1. Use VGM to open the .img file. The image file should show up in the upper pane of the VGM main window.
  2. Right-click on the image file, click on File -> Save As, change Save as type to .cmd, and save the file. This will save a text file.
  3. Edit this text file to make the following changes:
    • After IMGB command, add XRES and YRES commands which determine what the horizontal and vertical active resolutions are. For example, if you are going to use the image in 720p, then you need to add XRES 1280 and YRES 720. (If you are going to use the image in various resolutions, then you need to create multiple image files.)
    • Modify the IMGA command with an absolute path. For example, use IMGA /tffs0/library/userdata/image_name to create the files in /tffs0/library/userdata/. You can change this to wherever you want the files to reside, even the CompactFlash card (using /card0/ instead of /tffs0/ as the base device in the path).
  4. Connect to the generator’s command line interface (either RS232 serial or Telnet over TCP/IP Ethernet).
  5. Copy and paste the contents of the text file to the command line interface. The commands will be sent to the generator, and the custom image will be created in the 880 generator.
  6. Press SOURCE and select the format you want to use. You will need to select a format with the same resolution you selected in step 3A.
  7. Press the TOOLS button for two seconds to go into Browse mode. Browse to the location you specified to save the image file in step 3B.
  8. Select the custom image; then you should see the image on the display.
