I don't have a clue. Is your LCD 1080p or 720/768p? If it's 720/768p, you may be seeing some funny scaling. I checked the pattern on a 768p Samsung, and it looked okay.

I think it is some sort of chroma delay or something (analog VGA connect).

While my Vizio 32" display is 768p I use the Opera browser which by default crops and does not scale images. This means I can scroll big images left and right and on my display doing that changes the color of your highest frequency test pattern areas, from a red shift to a blue shift.

However normal images look fine on this display and I've generally been happy with it since I got it a couple months ago when I popped another $300 projector bulb. Very strange.

Just wanted to say thanks both to the author and the host of the files.

Any chance for these additional patterns to make a complete set of color window patterns, i.e:

Rec. 601 75% Color Window Patterns
Rec. 601 White Window 1920x1080


Rec. 709 75% Color Window Patterns
Rec. 709 White Window 1920x1080

The same would also be useful for the full field patterns and it would be excellent to have 100% Color patterns too.

Thank you for sharing all of the different patterns, Ron!

Thanks for the great test patterns! I used it yesterday to help calibrate my new HL61A750 DLP LED RPTV. Burned the ISO to a DVD to play on my Xbox 360 HD-DVD drive.

dr1394,

how did you generate the film based test patterns? I am not seeing the expected 3:2 pulldown use of the topfield/repeat first in the picture coding extension. Am I just brainfartng and way off course, long day.

thanks

I have a program that adds repeated fields to progressive YUV sequences.

http://www.w6rz.net/tele.c

Then the telecined YUV sequence is just encoded in video mode. This is also called "hard" telecine.

thanks for explanation and the test patterns

I think those tests are great and used them extensively. Any hope for some that test motion handling? eg: moving line bursts with different frequencies, bar sizes, speed...

dr1394,

I'm looking for a test pattern to test the Slingbox Pro HD. I want to know if the Slingbox is dropping the odd or even frame from the video signal, NTSC or ATSC which have 60 fields per second.

What HD test pattern could I use to prove this? The simplest thing would be a pattern where all odd frames had a number 1 and all even frames have a number 2.

In the end I could simple tell which frame is dropped because 1 of the numbers would be absent.

Does a pattern already exist for this? If so, can someone point me in the right direction? Thanks.

I've added the open source movie "Big Buck Bunny" to the w6rz.net website. To make it a little more interesting, it's coded with 4:2:2 chroma, which you don't see much of in HD resolution.

Ron
post #222 of 290
Sorry if this has already been addressed, but is there a pattern that can be used with a blue filter to set color and tint?

Thanks!

Hi Ron, I realize that this is from a few years ago but I was wondering if you ever got around to making the 5% increment white window patterns including the 75% white window needed by various software tools to do a color measure run? I don't see any on your site. Since I'm also a "C guy" , I've looked at ire.c that you wrote and can see how it should be fairly trivial to create .yuv files for each one of these patterns via the command line arguments but I don't have a lot of expertise in the area of encoding. It sounds like the basic mechanism is to use Avisynth combined with a MPEG-2 encoder such as TMPGEnc. My main goal is to produce MPEG-2 files that I can load onto the HD TIVO via the TIVO desktop software. Unfortunately, the MPEG-4 files from AVS-HD won't load even though TIVO says .mp4 files are supported (it looks like that they are not natively supported but are converted by the Desktop software to MPEG-2 - but that seems to be failing).

thanks for any insights/pointers and for the patterns,

Tom,
Can you turn your PM's on? I might be able to help but don't want to hijack Ron's thread.

Believe it or not, I actually coded the 5% increment patterns. I'm uploading them now. Check for the update tomorrow.

Thanks very much Ron. Just to let you know, the new files seem to be unzipped (unlike the existing ones).

cheers,

Yes, I forgot to zip them up. I'll fix that tonight. BTW, I also added some 100% REC709 color windows.

Hello Guys,

I am looking for SD IRE window patterns in mpeg2 ts format. This is for calibrating my dreambox sat receiver which does not do HD.

Are these available somewhere?

Regards,

Ronald

Here you go. My SD encoder isn't quite as easy to use as my HD encoder, so I put all the IRE windows (5 IRE steps), ramp and color bars into one big file.

I don't want to thread hijack either, but was really excited when I saw all the work you put into this. I was looking for a simple way to get patterns to my HD-Tivo to at least do a greyscale calibration on my TV source on my 32" Sharp Aquos, and this goes far beyond what I hoped for!

Anyone else looking to do this, google pytivo for windows or pytivox for mac. It basically eliminates the need for Tivo Desktop - as long as you can play it on your computer, you can stream it to the Tivo.


Thanks!!!

Hi Ron, not to be a pest but does this SD zip contain any 75% color window patterns? I haven't had chance to look at it yet. I also have a SD TIVO hooked up to an older tv which I've love to run through a calibration using SD versions of the 5% increment grayscale/white window patterns and the 75% Rec601 encoded RGBYCM window patterns. Thanks again for the HD versions of those patterns - they worked great to calibrate the HD TIVO.

cheers,

Wow, thanks a lot!!! :-)

Hopefully I can skip between the patterns in some way :P I'll try this weekend!

Unfortunatly it does not even play on my DM7000 dreambox sat receiver :-X

I notice you are in the Netherlands. Perhaps you need a PAL bitstream? I'll create a PAL stream for testing.

Here's a PAL bitstream to try on the DM7000.

http://www.w6rz.net/sdpaltest.zip

It's a loop of some test video. Also, the audio is MPEG-1 Layer 2 instead of AC3 (even though it's silent).

Hi Ron,

Yes I am in PAL territory ;-)

This has crossed my mind as well, but then I thought, the dreambox plays ntsc channels as well.. Anyway I'll download the sdpaltest and try !

Thanks for all the effort!

Nope, doesn't work either :P I'll try to figure out what the difference is between your transport stream and one recorder by the dreambox itself..

Ronald,

Have you tried extracting the MPEG from the transport stream and seeing if that will play on your DVR box? I had no problems playing the SD patterns MPEG on my older SD TIVO.

cheers,

Hi Ron,

After remuxing you paltest with a program called videoredo it does play on the dreambox!

Unfortunatly videoredo can't open your sdpat file you created before.

Hi Ron, in case you don't a chance to do some SD 75% color windows, I did notice that the color bars pattern at the end of SD grayscale+ramp patterns are just wide enough to use with my Eye-One so it did allow me to measure and set Tint - although setting Color via luminance measures was a bit trickier - it looks like those color bars are at 60% stimulus, is that right?

thanks again for your work on these patterns,
