Generating a Video Signal

To generate a video signal based on a bitmap image using the factory settings, select the proper options in the NI Video Generator Wizard dialog box.

In generate a video signal, complete the following steps:

  1. Make sure that the device ID is set to the correct value (configured by MAX).
  2. Select Load BMP file and compute video data.
  3. Click Browse.
  4. Double-click the appropriate directory from the following:
    • For NTSC users, double-click the 640x480 or the 1044x480 directory.
    • For PAL and SECAM users, double-click the 768x576 or the 1040x576 directory.
  5. Double-click any of the example .bmp files. The bitmap image file path now appears in BMP Input File Path.
  6. On the left side of the dialog box, select Use factory settings. This option applies the default video parameters to the video signal you are going to generate.
  7. On the right side of the dialog box, select M-NTSC, Standard-PAL, or SECAM, depending on the video format you want to generate.
  8. Select Download video data file. This option downloads the binary video data from the computer to the NI PXI/PCI-5431.
  9. Click Finish. A Processing dialog box appears to show you the processing status.
Note  If you select Display BMP next to Browse, when you click Finish in step 9, you can see the .bmp file displayed on the computer monitor.

Based on the .bmp file you selected, the NI Video Generator Wizard calculates an NTSC, PAL, or SECAM video data, downloads the calculated data to the NI 5431, and automatically starts the generation of the video signal on the analog video output connector.
