Faroudja test images (1 Viewer)

I was just looking at the Kenwood Advertisement/Test DVD that finally came in the mail (link below) and I have a question.
There is no accompanying explanation with the Faroudja test images. If someone has the disc and is familiar with them could you tell me how those specific images are used? What do you look for in each image and such?

Thanks,

Was it just me, or do those test images of outdoor scenes look super-saturated and rather unnatural compared to any well-mastered DVD?
I agree that Kenwood should have included some instructions on what to look for with the pendulum tests etc. But since all those tests are related to DCDi and deinterlacing performance, think in terms of what those features do-- i.e. do you jaggy edges on diagonals, or are they smooth?

The first few tests, which include black and white burst type test, outdoor photos, and cartoon are for the cross-color suppressor. They don't really do a lot for DVD since it is a component format. However, they can be used to test comb filters in TVs and video processors if you use the composite output of your DVD player.
The swinging pendulum is for DCDi. You can turn it on and off in some faroudja products. If you have another DVD player like a Genesis based one it is easy to see.
I think this disc also has one with OK at the bottom of the screen and a rotating logo. The O is in field 1 and the K in field 2. This is a motion-adaptive test. It lets you see how the video mode deinterlacing is. (or what type.) Play this back on a non-motion-adaptive player and you will see some interesting stuff.
Flag is DCDi. You really have to play this on a Genesis based player or turn off DCDi to appreciate.
Was the Hockey player test on this disc? If so, another DCDi test. It is video footage and you can see DCDi really do its thing.
If there is anything I missed, let me know and I will tell you what it does.

The swinging pendulum is an excellent test for RPTV "haloing", which my Sony KP-53HS10 definitly has

Stacey,
Can you tell us what the test pattern after the American flag is? Its the one with a horizontal and vertical patterns moving from upper right to lower left across the screen.
This is the only pattern my iScan pro failed. I know the lines are supposed to stay solid as they move, but they flicker on my set. The iScan pro is in "Film" mode, but I'm guessing this is just flagged incorrectly on purpose.
What do you think?

Let me see if I can locate my notes.

That test with the moving lines showed my convergence was off on the right edge of the screen. And the swinging pendulum showed haloing, made me think about felting the inside of the set...
Interesting test patterns, if they only explained what each was for. That was a major flaw, oh well, it was free and cool.

i didn't know what to do with the tests either, but one thing for sure - on the flag screen, it really showed some jagged edges on my setup.

one question: when i paused, the jagged edges seemed even more pronounced. does that indicate anything?
time for progressive dvd & hd set!

Stacey,
Any luck on finding out what that final pattern on the Kenwood DVD tests?
