AVT-8710 vs 1T-TBC vs TBC-1000 (TBC-100)
 
1 Attachment(s)
Hello everyone, first post. :)

Got my 1T-TBC today -- inspired by this thread I thought I could post my findings.

The circuit board is similar but not the same as AVT-8710.

Components are not directly attacted to the metal casing so it does not provide any cooling per se. But the board / components don't seem to get very hot so it likely doesn't matter (12h on).

Picture is sharp and almost noise free (compared to my TBC-1000 this is a big improvement).

Thanks for sharing your experience! Very interesting information. :)

In my experience, TBC-1000 noise is caused by the electrical issues in the home or office where it's being used. It's apparently more touchy than some other TBCs out there -- I've had this experience, too. There are also some models from a few years there were softness was an issue (I've only seen this from submitted captures, never directly on equipment I've used).

Where did you buy this, and what was its cost?

juhok 09-18-2009 05:50 AM

My TBC-1000 issue might very well be due to what you said. It's from eBay and I don't know it's history. 110V/60Hz PSU was replaced by 220V/50Hz switching-PSU and that might play a role too. To be fair the softness issues don't affect luma -channel so much, only chroma gets blurred and that doesn't make correcting VHS chroma shift etc very easy.

Last night I tested 1T-TBC vs TBC-1000 with tapes who produce vertical jitter which has been problem for me from time to time. I'm to happy say that 1T-TBC performs better in that area. Compared to TBC-1000 the jumps are still there but the effect is a lot more subtle and I can only spot the jumps when watching frame-by-frame. This is only one test with one tape tho and time will tell more.

Colorbar generator was a really nice bonus. It wasn't mentioned in the spec sheet (atleast I didn't find it). It's activated when there's no signal input. Together with AGC this makes calibrating the capture levels easier (I'm using bt878 based SweetSpot/PDI Deluxe card).

1T-TBC was bought directly from AV Toolbox's UK store and cost 191 euros (VAT0). Very fair deal imho. :D

admin 09-18-2009 02:11 PM

Hmm, interesting .... that appears to be the AVT-8710 in another shell. Same features from what I can tell.

Chroma does occupy less space than luma, in the 4:2:2 or 4:2:0 processing commonly used in these devices. So it can appear softer, but luma should create the "detail" of the scene anyway. It's definitely possible that the TBC-1000 you have is soft, especially if it were damaged earlier in its lifetime. But I would warn that sometimes a device that oversharpens can make an accurate device seem "soft" by comparison. Verify without any TBC, then compare both images with TBC, to see if one is really softer (or sharper) than the other.

That is good news on the jitter! In tests performs years ago, the TBC-1000 was better than the AVT-8710, so I now wonder if the 1T-TBC is a copy of the AVT-8710 or not. Or maybe the 8710 has advanced in the past 4-5 years since I last did A/B comparisons. (Or maybe it's just more kind to your particular tapes! So many variables to work with here.)

Electrical issue from power supply replacement are possible. Sometimes "fixing" the power electrical issue is as simple as putting the device on a UPS (uninterrupted power supply) that has voltage regulation. APC branded UPS, for example, has AVR (automatic voltage regulation). This works quite well in our setup, to keep the various systems and devices free of most electric noise. Direct connection to a wall outlet or basic surge strip tend to show noise on a VCR or TBC, best seen on a bluescreen or test pattern.

Indeed, the price looks decent, especially for that side of the pond. You made off well, getting a good new TBC for that price.

Double check the softness/sharpness issue, let me know how the three signals compare (VCR only, +TBC-1000, +1T-TBC).

Do keep in touch on jumping, that is interesting, and good to know. It's something not only potentially useful to readers/members of this site, but to me as well.

Thanks for sharing! :)

juhok 09-23-2009 08:01 AM

TBC-1000 softness was observed when comparing directly to the source without TBC. I will look in to the electrical issue some time, online filtering UPS's are quite expensive.

There seem to be some issues with 1T-TBC after observing some more. But I have to investigate this more thoroughly when I have time. I will post comparisons then. If you have some hints on generating test tapes / links to usable testcharts in downloadable format (like DVD or raw YUY2 etc) that'd help. So far I've observed client's tapes (my current occupation is to transfer old tapes, also my 'hobby') and colorbar generator.

Right now I need new heads for NV-FS200 and HM-DR10000EU (anyone? :)), after those get fixed I can run some tests.

admin 09-25-2009 12:07 AM

Hmm... My knowledge of VCRs does admitted get more rusty as the years past (use it or lose it!), but I wonder if the heads from the USA NTSC Panasonic AG-1980P would be interchangeable with the UK PAL Panasonic NV-FS200. They are essentially the same machines, PAL/NTSC aside. Those may be easier to locate, albeit more pricey to ship. There is the benefit, however, of having abundant units out there, especially "for parts only" sales.

juhok 09-25-2009 05:41 AM

Atleast in the case of HM-DR10000EU for which I bought service manual the "DRUM SUB ASSY (PDM2312E)" is the same part in many different models, including NTSC ones. Assuming this is the right part, I'm not 100% sure yet because the terminology changes a bit with different VCR's. I found NV-FS200 heads - again, if it's the right part - from http://www.donberg.ie/ and it seems to be compatible with AG-1980P too.

Addition; According to Dönberg the part I'm looking for JVC D-VHS is

admin 09-28-2009 03:48 AM

The JVC D-VHS series is supposed to share a lot of parts from the JVC S-VHS 7000 and 9000 series latter-generation models. For example, the 9900, 9911, SR-V10, SR-V101, 7800, 7900. I've never compared parts piece by piece, but this was something JVC confirmed some 5+ years ago.

So you may be able to gut a "for parts only" JVC deck, one where the heads are good, but maybe the board or PSU is bad.

juhok 01-12-2010 07:30 PM

Things took a different turn with 1T-TBC. Long story short; it didn't work so good with problem tapes, I lost my patience and sold it. Pretty horrid results (freezed frames for a long periods of time). The stripe problem was propably due to setting sharpness too high (aka the default). Setting it to lower position fixed it (propably, didn't test this one a lot anymore). I'm not saying it's useless. It works fine with many tapes but I rather have a device that works always when working with dozens of tapes a week.

This might've been PAL problem and it works better in NTSC? Who knows.

I must say I'm very disapointed with their tech support which touts being "the best in industry" but I haven't received single reply to my queries after several months.

Also discovered what's causing the problems with my TBC-1000. The input connector is somewhat borked and occasionally gives worse results. Slight push will fix it usually. I've ordered new connectors (and I'm going to throw away the 1->4 distribution amplifier and connect in+out directly to the TBC-100 -board).

I did a test regarding sharpness and comb filter at doom9 and the results might be relevant to readers here so I'll repost the images;

You know what!? I had never considered hacking apart a TBC-1000 and disconnecting the distribution amp. I wonder how many of the "vertical bars, vertical lines" and "softness" problems sometimes reported to this units may be related? After all, those same complaints are common with lower-end distribution amps. You never hear complaints about the TBC-100, which is a PCI slotted version with no amp.

The PNG for the 1T-TBC is awfully noisy. I see a bunch of compression artifacts, like JPEG/MPEG noise. If the PNG is truly 24-bit, and those are passed from the TBC, that's sad.

Not a bad doom9 thread, but it looks like you didn't get a lot of feedback. I did see once useful nugget of info on VCRs:
Quote:

BLAUPUNKT RTV-950 = Panasonic NV-FS200
Metz S-VHS VC62 = Panasonic NV-HS950
Blaupunkt RTV-965 = Panasonic NV-HS1000
Good for remembering. I've been trying to track down rebadges on a lot fo the older and higher-end VCRs. That helps.

The 1T-TBC is really smeary, too. Ugh.

DataVideo TBC-1000 about as expected. There can be slight resolution loss on a TBC, but it's something you really have to look for in an anal-retentive kind of way. I see it when I eagle-eye it.

The PDI looks artificially sharp. I see ringing. Watch for that. "Nice and sharp" isn't always a good thing.

Thanks so much for sharing your results. This is great information for myself and other members/readers of this site.

Keep me posted on your experiences, it makes for good reading. :)

juhok 01-14-2010 08:50 AM

Hi,

a Few notes about the testing.

The PNG images are true 1:1 representations of the 4:2:0 capture.

Charts come from TVblink.com "test suite" and are played back using consumer DVD player. Both pose limitations to the actual testing as we can see. DVD suffers from MPEG2 artifacts which are amplified by the decoder in my DVD player. I've added "pure" versions of the screens decoded with DGMPGDec's "IEEE-1180 reference" iDCT algorithm + resolution chart with exaggerated luma;

http://www.siluriformes.net/doom9/DVD_Resolution.png
http://www.siluriformes.net/doom9/DV...tion_lines.png
http://www.siluriformes.net/doom9/DV...ution_luma.png

About the smearing, this test was purely about comb filter, composite -> Y/C separation. When feeding with Y/C signal 1T-TBC works as expected. Altho it *does* add unwanted distortions to the image atleast with high proc amp settings like I've shortly described before.

PDI might be a bit too sharp. But I've compared it a lot with software decoded DVDs Vs captured ones and it doesn't add much ringing of it's own IMHO. What we're seeing here propably is due to DVD player/composite related. I just ordered Blackmagic Decklink Studio (found one slightly used for a good price) which should give a good reference to this all. It can output very decent test images and I really hope it can capture them well too :p. I didn't choose the ATI route that's often suggested here because I need all the inputs+outs up to component and SDI with balanced audio. If it doesn't play with my other gear / software I'll try AJA cards next. Painfully expensive.. but other options aren't much cheaper.

TBC-1000 with dist.amp. stripped should work quite like TBC-100 because it is one :D The circuit board inside is a PCI card with PC style 12+5V molex connecter and has "TBC-100" printed on it. :p Be warned, if someone reading this tries to connect his 12+5V power to stripped TBC-100 board, things might go wrong. It's missing a voltage regulator (I guess from the pictures I found about "real" TBC-100). And my version is missing 3/4 of it connectors. I don't really know why they left one RCA plug in place. There's absolutely no use for it inside the box.

I stand corrected. Blackmagic S-video input is a lot better. Cannot blame the DVD player now. :o

http://cdn4.digitalFAQ.com/juhok/BM-...resolution.png

In related news, BM composite is not a whole lot better. Still dot crawl.

admin 01-15-2010 02:47 PM

I almost never used the RCA audio passthrough on the TBC-1000, I just wired around it unless I was specifically using the distribution amp (which wasn't too often as years went by).

Ah-ha! I told you. :p I've gotten pretty good at detecting false sharpening in recent years.

Good skill to have when editing, terrible skill to have when trying to watch TV. (Hard to enjoy something when you notice all the errors.)

I doubt you'll ever be satisfied with composite, especially not under analysis with test patterns. But as long as it;s "good enough", it will serve its purpose as the fall-back connection method, when s-video throughput looks bad or s-video is unavailable.

One trick I've learned is that sometimes -- even on the cheap $5 units -- the svideo>composite adapters can look better than native composite output. It only works in certain situations, but it works nonethless. I use one of those on the office TV, s-video out from DVD player, switchover adapter to composite, into the TV. Entertainment while I work on the no-brainer type projects.

I want to add an Aja Kona or Blackmagic card here, too. So your research is interesting.

juhok 01-15-2010 04:42 PM

By RCA I meant the connectors directly attached to TBC-100 board which are unexposed if you don't remove the metal cover. Anyway, I don't use the audio pass-thru either. Once when I measured my soundcards audio delay I checked how much effect the pass-thru had. Result was;

DelayAudio(-0.170) # Video TBC, Audio Direct
DelayAudio(-0.152) # Video TBC, Audio TBC

18 milliseconds delay compared to direct. :p (so I guess they compensate for the video delay)

After quick eyeballing BM seems to be exactly what they were advertising. No problems with VHS etc when using TBC-1000. Quality clearly better than PDI (which already was very good). Capturing thru VirtualDub works fine (I can use ffdshow's codecs with it like Huffyuv). The final test is to see whether I can drag all my hardware and software to Windows 7 and finally get all 6GB of RAM in use. :D I feel that AJA couldn't offer me much more personally. And AJA costs 2x as much if HD is a must. If you want some test etc with BM done just ask. This stuff needs it's own thread soon. :)

admin 01-15-2010 05:00 PM

BM + VirtualDub = good news, indeed.

Windows 7? Good luck with that. :D
I might have to go that path on a system here soon too. Coincidentally, it would be the system that would receive a Blackmagic upgrade. So yet again, your research will prove useful.

Yep, new thread is probably in order.

Hi juhok, I will receive my TBC 1000 soon and I am interested to do a hardware mod like you described (strip off the distributor).
If it's not a big problem, could you upload an image of your mod?

I was trying to get some pictures a while ago but the screwholes are covered with this tape (I don't know english word for it) which allows mounting and removing it fast from the rack. I'll try to peel of the parts covering the screws someday when I have time.

The mod is basicly pretty straightforward if you know a bit about soldering and electronics. You can see (or measure) what cables go where. In the back I drilled new holes for new SVHS connector and used BNC connectors for the composite.

Was not very happy with my JVC HR S8960E I bought new years ago. (DNR leaves artifacts sometimes).
Only thing that's still left on my to do list is exchange the ADVC 110 to a Backmagic Intensity Shuttle well and probably do the TBC-1000 mod as well.

juhok 02-24-2011 01:22 PM

It's worth mentioning that if your TBC-1000 works without faults, the mod won't propably affect the PQ much. I did it because there were real problems. :)

My TBC 1000 does not seem to suffer problems like weared connectors but anyway I did a quick mod on the TBC 1000 without needing to modify the TBC 1000 itself.
I took an old internal CD Audio cable dissected the plugs and soldered on a S-Video cable on it put on some shrink tubes and here we go:

Attachment 1305
http://img852.imageshack.us/img852/357/tbc10003.jpg

Took me probably ~1 hour to build the cable.

So it's possible to plug off the output cable from the TBC 100 circuit board that runs to the distribution board and plug this cable in and connect it directly to (in my case) the BM intensity shuttle. If the distribution is needed just re-plug in the other cable.
Maybe I'll do a second one for the input side also.

BTW: the intensity shuttle is a really nice device - I'm stunned with the quality :)
In contrast to some reviews on amazon it only took me 5 minutes to set up the device and capture the first video in virtualdub. (Did the homework before and updated the drivers and firmware of my USB 3.0 card).

VHS capture without a full frame TBC and the blackmagic intensity shuttle is a no go! A full frame TBC in between is an absolute must in this case.

The connectors Datavideo uses in the PCB aren't really "video qualified" anyway..
Interesting. I wonder if that causes the sometimes-visible "bars" that some owners have seen on their units. However, I still think much of that is related to dirty incoming power, and lack of any AVR on a UPS (assuming they're even using a UPS).

EDIT:
Hmmmm.... you just edited this out of your post. What did you miss?

juhok 03-04-2011 05:00 PM

I misread that Bugs.Bunny used CD-audio cable, when he was really using just the connector. What I noted about the internal connectors which are propably not rated 75ohm holds true. It likely doesn't affect the picture in a meaninfull way tho.

Did solder a second cable for the input side now as well. Hard to say if there is a big difference between direct wired and normal wired (with the distributor). Maybe it's a bit sharper direct wired. Have no DVD player around here to do some testing like juhok.
Did also exchange the original 120V Adapter + transformer 220V->120V (this way I got it from ebay) to one that works from 100 to 240V and is rated for use with medical equipment (I've got 230V here). One from http://dehner.net/en The TBC 1000 works fine with it.
Before the power consumption of the TBC 1000 was ~38W now it's 9W (checked it with a cheap watt-meter).

What I would like to know is how much the TBC 1000 delays the video compared to audio. Is there a free test clip I can download then record on vhs and then capture and look in adobe audition how much video was delayed to audio?

In the virtual dub capture / timing dialogue there is an option about audio latency determination.
I've currently set the timing options this way:

Last time I checked there was 8 millisecond delay. That's neglible. The test clip was created with avisynth "Colorbars()" and recorded to DVD. TBC-1000 does not incorporate audio delay circuitry and the audio is only pass-thru. This small one frame delay is nothing to worry about.

IIRC they're at defaults.

kpmedia 03-12-2011 06:54 PM

The delay is either 1 frame, or half of 1 frame. I forget which it is.

Tranzor 05-02-2011 09:55 PM

Would anyone mind upping some pics of a modded tbc-1000? I know Bugs.Bunny upped some pictures, but they are the tbc default with the cover off. I am having some issues that developed sort of recently and I am not exactly sure what may be the cause of it. Lord Smurf pointed me over to this thread here.

To make a long story short please check the link below for my original post on videohelp.com. I also upped a video clip of what my TBC was doing. I do have a new power plug for it as well as a higher end belkin surge device (that supposedly cleans power as well), but the problem returned the

I don't know that you need any more images. Simply create a cable as shown in post #24, and then unplug the 4-pin coming from the mainboard (see images in post #22), and replace it with your custom s-video cable. That will bypass the distribution amp on the back end of the unit.

Look at the photo/diagram, and understand how this TBC works. Follow the wires. Audio passes from the inputs directly to the output board on back. Video passes from the input to the TBC board. It's a TBC-100 PCI card, and even has the "slot" piece shown inside this TBC-1000. Video then passes out of the TBC-100 back into the split amped outputs. Disconnect it at this stage, from the mainboard, and substitute your own wire. Don't bother with the audio either, pass directly from the VCR to the recorder card/device. Just skip the distribution amp entirely.

Does that make sense?

Sure, more photos may help it become more obvious, but it's really not all that necessary. :)

Yes it does. I had to take a much closer look at the printing on the main circuit board to see the label of "in and out".
Let me ask now, I know I have one of those older cd 4 pins somewhere that came with an older dvd/cd drive. However is it a simple match up the wire type splice or is it a bit more involved when making it??

lordsmurf 05-03-2011 04:15 AM

PM Bugs.Bunny, and ask that he post the answer here. :)

Just as a guess, I'm thinking it's a simple wire to wire match. At least that's how his photos look. Pretty much everything I would have suggested or thought of is already written in the thread so far.

Then I soldered the s-video cable on the pins I disassembled, then put shrinking tubes on the cables and reassembled the plug.

Thank you for the reply. Ignore the PM I just sent as I did not see your post first

just wanted to say that Bugsbunny was kind enough to sell me some of his modified wires. In my TBC's case I am hoping it is just the output that is bad, so I do not have to do any further modding to the actual case. It looks a bit crude, but does the job (did a quick test, did not have time to do a full film to see if the problem occurs). I then attached an svhs coupler jack to his wire. Yes I also sealed up the hole that appears on the top where the wire is fed through, I would not leave it open like that. PS: please disregard the mess with the other wires in the pic, everything has been cleaned up

Hi, I think a good tutorial explaining how to do those mods will be welcome for everybody, especially for people that doesn't have any knowledge or experience with electronics, including me. That will be helpfull, at least.

Also, maybe a bit more informations about the parts that have been tempered with and where to find them (whit links to them).

Thanks again and keep on the good works.

I bought a DataVideo VP-299, hoping to just add the TBC-100 to make a TBC-1000, but the power supplies are completely different.
I'm not exactly sure how to proceed.

ARRGGHHH! :mad:

Anyone know where i can buy one of those little connectors to make up a lead like above to disconnect the distribution amp?
Do those connectors have astandard name?
Thanks

I thought i already posted this but it must of got deleted or something. I have seen inside 2 different TBC1000. There is clearly 2 different TBC1000's out there that use different TBC100. If you look back the photos in this thread, you can see some components on a orange PCB. I have photos of a TBC1000 that does not have these components on the PCB. The 3 legged device whos name escapes me is mounted on the TBC100 in the photos i have. Not sure if the capacitors and diode are scattered around the place (not counted the capacitors) but its clearly different as to where they feed the power into the TBC100. I have never seen this mentioned before. I dont know how different the separate TBC100 are when you buy them but they have clearly stripped some components off that board in the photos above and mounted them on a separate orange PCB but on the version i have there is no separate orange board and appears to be an unmodified TBC100. I wonder if this accounts for varing results when using the TBC1000. Everyone will be lifting the hood on their TBC1000 now. Which version do you have? I wonder if we can work out when each version was made?
