DVDO AVLab TPG - 4K Test Pattern Generator

DVDO AVLab TPG 30 A.04

will be 16, 128, 128 (limited range black YCbCr).

The window size is given in %. For more details see the serial control spec and examples in Appendix A.

For Firmware version 01.01 and later, the new full triplet command is implemented allowing software to

send the exact 0-255 RGB value to AVLab for more precision. This command is detailed in Appendix A with

examples. To make the color more precise, all controls that could affect the outcome are included in this

single command which overrides all output settings from the On-Screen-Display or previously set via serial

commands. This includes:

• Input range (That 0-255 triplet of 16, 16, 16 – did you give it to AVLab as limited range where you

mean black or did you provide full range and meant grey)

• Output Color space – output the color in RGB, YC 444, YC 422 (except in 4K/60 where is it 4:2:0)

• Output range – limited or full – note that this affects both the numeric value as well as the info

frame that the TV uses to interpret the value

• Window size – given in % from 0-100 (although a 0% window is non existent)

• Window background color – given as an absolute decimal number from 0-255. Normally this is just

set as black (0 for full range, 16 for limited range), but if the software is asked to provide a constant

APL (Average power level – meaning the background changes to balance the overall brightness of

the color and window size in the main window so that Plasma TVs do not try to auto adjust overall

screen brightness) it can be provided to AVLab.
