DVDO AVLab TPG User Guide

LightSpace CMS can be integrated with the AVLab DVDO Test Pattern Generator for accurate patch generation, enabling Closed Loop display profiling.

The following instructions are for using the AVLab DVDO Test Pattern Generator for calibration with LightSpace CMS.


Initial Operation

DVDO AVLab TPG

Operation of the DVDO AVLab TPG with LightSpace CMS is exceptionally simple.

  • Connect the DVDO AVLab TPG to the LightSpace PC via the supplied USB cable, and start LightSpace CMS.
  • Navigate to File/Upload, and select the Dvdo from the 'Select the device type' drop-down window.
  • Select the correct COMS port for connection
  • Using the 'Calibration Patches' option select the desired patch size and background level to use.
    (Note: the patch size % box defines the percentage height & width, not 'area', and the BG is the background level in integer values from 0-255.)
  • Use the signal range drop-down to select Video (TV legal) or Data range, rescaling the output signal as required.
  • Close the 'Upload' menu.
DVDO Upload

The Upload menu is located under 'File/Upload'.


Profiling Operation

To use the DVDO AVLab TPG as a Patch Generator with LightSpace navigate to the desired profiling mode - Calibration Interface, or Display Characterisation.

When the patch window is activate (the LightSpace CMS internal floating patch window has been made active by clicking the small colour display box when using Quick Profiling or Manual Measure modes) the output of the DVDO AVLab TPG will mimic the colour displayed, using the patch size pre-set via the 'Upload' window.

Profiling can then be performed as normal, using the probe connected to LightSpace, and with the DVDO AVLab TPG displaying the required patches on the display being profiled.
