AVT-8710 Time Based Corrector

[daz_raven2010]

Has anyone used this TBC from AV ToolBox to get rid of Macrovision and other copyright stuff while recording from DVD to a DVD recorder. I have a PAnasonic DMR-E30 recorder.

[ejai]

I have one, I LOVE IT!

Yes it works fine on the E30 and the E50, I'm sure it works well on all the models. Not only does it bypass the macrovision (on dvds and tapes) it also has video enhancement features such as: sharpness, tint, color, brightness and contrast, all in one small unit that fits in your shirt pocket.

This unit also works with either PAL or NTSC. I also have the Datavideo TBC 1000, but I only use the AVT8710.

Anyone know where to get one in Canada? or something similar to it?

If that does not work, try this:

I originally got an 8710 to get pass the macrovision, which it does beautifully, but have found the picture adjustments even more valuable. Especially to correct the black level when recording with the pan e30. The improvement is enough that I am considering redoing everything I still have the source tape of. Then again turning down the brightness on the tv seems to just as good and a lot less work. Decisions, decisions.

WOW Thats expensive, ship to Canada possible customs charges, nah thats okay, I will have to stick with my RF Modulator for now. Anyone know where, in Canada, to get the Sima Video thinga magigy?

Looks like the AVT-8710 is manufactured by www.cypress.com.tw

Browse their pages and you'll see that you can buy the stuff yourself from Cypress and put your own brand on it. They advise you that all you have to do is silk screen your logo on the product.

Appears that's what AVToolBox www.avtoolbox.com does.

The Cypress product model number is CTB-100. Then, AVToolBox seems to put their AVT-8710 model number on it.

Another interesting thing to me is the fact that DataVideo and Cypress are in the same city in Taiwan.

Another interesting thing to me is that one poster in the forums says that he has both the AVToolBox AVT-8710 and the DataVideo TBC-1000 and he reports both show vertical line artifacts.

As I examine closely the specifications and control functions of DataVideo products and Cypress products (branded as AVToolbox in the USA), it seems there are many exact matches between specifications and control button operation.

This leads me to wonder if the same chips are used in both. (The vertical line artifact found in both really makes me think they are using the same chips.)

Could be they are more than just the same chips ... but the same electronics, as well?

I have one which I use with my E50 recorder to backup VHS tapes. Seems to work great so far.

[ejai]

The artifacts are common especially on vhs captures. I've experienced them quite a bit. I've also found a workaround, I input the signal using the composite and output using svideo.

This seems to help in most cases.

[quasar1963]

That's really wild that they look identical (and most likely are)
Well, I will say it is a great device for making "back-ups".
However, I have had to use much the same the work-around recommended by ejai for making cleaner looking transfers.

so, the connection is sVideo between AVT-8710 and the DVD recorder and composite between VCR and AVT-8710?

just make sure I have this right.

thanks

[ejai]

Or visa-versa, you can swap it and see which way works better for your system. Just remember to use s-video in conjuction with composite, you seem to have stated it correctly, I just can't remember in what order I have them plugged in.

[zanos]

this thing is nothing but a glorified color enhancer.

[quasar1963]

Although it is a completely effective macro-remover

[FulciLives]

this thing is nothing but a glorified color enhancer.

My understanding is that it is a full frame TBC and more than JUST a color enhancer.

I'd like you to please back up this statement if you can. The burdon of proof is one you based on all that I have read.

No I haven't actually used this device myself.

Thank you VideoJockey2002 for providing that information about Cypress Technology.

[ejai]

I couldn't say if the TBC function on this device is any good, all I wanted it for was macrovision removal which it does flawlessly. The added color and brigthness adjustments are just nice add ons.

I have several TBC devices so that wasn't a major concern for me, even my Panasonic E50 has TBC built in, I'm satisfied.

Nope it's just a color corrector which is actually what I had meant to say. Not only does this do little if any kind of "correcting" but the expensive ones from datavideo aren't any better. I've used them all and the best seems to be in the panasonic dvd recorders. It's a good addition to the jvc svhs vcrs. Combine all this with a sima color corrector and you're set.

[ejai]

I too have the Datavideo TBC and agree that the Panasonic built in TBC's do a much better job. The only problem is the Macrovision and that is why I own these other devices. 8)

Here's a link describing the CTB-100.

http://www.cypltd.co.uk/ctb100.html

It says that the CTB-100GR version does genlock. It's difficult to see how this unit could do genlock without a TBC and frame memory. It must be more than just a color corrector.

The 8710 is supposed to be a TBC and frame synchronizer, which means it would have to be more than just a color corrector.

[nixie]

Also, what do these vertical artifacts look like when using the 8710?

The TBCs in the Panny recorders basically do nothing.
You must have a VERY DEFECTIVE Datavideo TBC, to say that.

[lordsmurf]

People too often confuse noise reduction (NR) with time base correction (TBC).

JVC has merged these into one unit.

Panasonic probably has some minor little NR in it, and people think it's the TBC. The TBC is worthless, and the NR is about as strong as the NR from my DR-1000. That's not much.

[ejai]

I agree with Lordsmurf, it is definately the noise reduction that makes the difference. I too sometimes refer to the TBC as a noise reduction feature and it is not. I stand corrected.

I remember reading this thread in my travels.. and forgot about it, until
this thread..

--> Checker Board Pattern from VHS to DVD Capture

Also, what do these vertical artifacts look like when using the 8710?

I too, am *still* waiting to see what these "verticle lines" are
(and I'm wondering if the above subject thread is this, unknown)

(blame the above thread for this threads' resurection)

Thanks,

Hi Everyone,

How do you use the AVT-8710 to reduce the "noise" in a VHS capture? I have this problem when I capture a VHS tape with my ADS Instant DVD box. Other than a loud static noise, the image looks great. Thanks in advance for your comments.
