For people interesting to use PGenerator, its been tested using Raspberry: Pi 2 Model B / Pi 3 Model B / Pi 3 Model B+ hardware. We recommend these hardware options.

Currently Pi 4 Model B is not supported, but it will be added support (if the testing goes fine) next month probably.

The developer of PGenerator is just an enthusiast, he has provided a lot of free tools to the calibration community.

When the guide I will prepare will be ready with pictures and details about how to setup/use, for those who experience any problem with current instructions, it will be easier from all to get a unit from any store and just follow the super-detailed instructions.

Recently I decided to purchase a DVDO AVLab TPG to help automate my ChromaPure calibrations. As previously mentioned in this thread the DVDO with firmware 1.03 has the cool colorchecker feature which allows one to test whether or not your calibration source's output is bit perfect.

I believe someone mentioned earlier in the thread that the Oppo 203 4K player is bit perfect on output. Of course being the nerd that I am I had to confirm this with my own setup! ConnecTEDDD was kind enough to send me a spreadsheet containing the expected YCbCr triplets for the CalMan color checker classic patches that are found on his excellent Ted's Lightspace CMS bluray disk version 1.1. So I set the Oppo 203 (on latest official 65-0131 firmware) to output [email protected] fps, YCbCr 4:4:4, and 8 bits per channel. I set the DVDO to passthrough, connected the output cable from my Oppo to the DVDO input, and then hooked another HDMI cable from the DVDO output directly to the HDMI 2 input of my LG C6P OLED display. I then activated the colorchecker function on the DVDO and started measuring the YCbCr values of the CalMan color checker patches from Ted's bluray disk. The results are attached...as you can see all patches measured perfectly with no digital errors. This is important to me because I like to calibrate my LG C6 manually using Ted's ChromaPure specific patterns. I will now use ChromaPure in conjunction with the DVDO to automate all of the post calibration measurements.

Hi, I have performed the same test with OPPO 203/205 from drive and from USB, both players had bit-perfect digital output for YCbCr: https://www.avsforum.com/forum/149-b...l#post51029553

Some more info about how these kind of tests can be performed:

HDMI Video Signal Evaluation using Digital Pixel Analysis

For HDMI video output accuracy testing, the most accurate way is to use a device which can examine the HDMI Input signal pixels with digital level analysis.



There available some very expensive solutions for such testing in professional market, like Quantum Data 882EA-HDMI Video Generator / Analyzer, Tektronix WFM5250 SDI/HDMI Waveform Monitor or using Dolby's PRM-4200/4220 Professional Reference Monitors 'Pixel Cursor Display' function.



In the professional market but with more 'consumer friendly' price level, there two Reference Pattern Generators with Pixel Analysis capability: DVDO AVLab TPG 4K Reference Pattern Generator and Accupel DVG-6000 Ultra Plus (with Engineering Option).

Unfortunately, both products have been discontinued now.

DVDO can analyze SDR up to 1080p60 input signal while Accupel can analyze additionally HDR10 also, but its HDMI 2.0a Input board is limited to 10.2 Gbit data rates (not 18 Gbit).

DVDO's AVLab TPG 4K Reference Pattern Generator (Firmware 01.03.769) features a very useful feature called as 'Color Checker'.



Using that feature it can provide real-time digital value analysis (RGB or YCbCR value) of the selected pixel from DVDO cursor.

The top left corner of the cursor box indicates the position of the pixel being measured.

The cursor box can be moved around the screen to select the specific pixel/area to measure using the directional arrows on the AVLab-TPG.

This test can show if the pattern is solid or each pixel has different values from internal device processing.

Professional & Enthusiast calibrators has found this feature very valuable, to check the accuracy of any player output, testing various colorspace output options:

Hi
I want to use for Calman and LightSpace (trial) MADTPG calibration patterns.
When I switch MADTPG after opening on my Sony OLED, I see that the menu bar of the software as on the attachment is still present during the calibration .Is this normal?
IF I select "use fullscreens", nothing happens. I always have this menu bar where you can select some options or disable others?
What should you do?

thank you. sorry for my English . I am French and I try to understand the software.

Laurent

Hi Laurent,

You have to double clip madVR TPG screen.

Can the PGenerator software be used by the new Calman Home for Sony, Samsung, Panasonic, etc? Will Calman recognize the PGenerator RPi device and will it automatically send necessary patterns? Does it support both SDR and HDR color patterns?

I am thinking of buying the Calman package with the C6 meter but don't have a pattern generator and this would be a godsend over spending the $1495 required for the SourceForge Pattern Generator.

Hi,

PGenerator can work with all CalMAN Home versions, you will connect as ''SpectraCal Unified Pattern Generator Control Interface''.

Its been tested using Raspberry: Pi 2 Model B / Pi 3 Model B / Pi 3 Model B+ hardware. Currently we recommend only these hardware options only.

It will support bit-perfect patch generation of RGB-Video triplets, not other colorspace. (of RGB-Full if you like).

As standalone device it can't generate HDR10 patterns since its HDMI 1.4.

But at the output of Raspberry is you connect an HD Fury device as HDR10 metadata/AVI infoframe injection device then you will be able to convert the RGB-Video SDR to RGB-Video HDR10 patterns.

But there no HD Fury device right now which is working when you will direct operate it from inside CalMAN. At past it was supported the HDFury Intergral (1), but the last time it worked, it has before a software release update of CalMAN @ August 2017 with HD Fury Integral (1).

But you can use the HD Fury GUI utility with any HD Fury device to add the metadata manually.

You 'virtually' connect from inside CalMAN the AVTOPcontroller, and from there it will generate for you the metadata/infoframe and later you import them to HD Fury GUI.
