CED VideoDisc and Player Discussion

Anyone got schematics for the models w/stereo adapter ports? I should be able to suss out what's being fed to it, at least...

Jesse - that got me curious - turns out it's a hybrid of broadcast FM and LD - there are two FM carriers - the 716khz signal is L+R, and the 905khz is L-R. (source: page 15 of the SJT-400 SM, http:/ ...

I looked at the RCA annual reports - in 1986 RCA was actually financially quite healthy and profitable, and with some more reading I found that Bradshaw (the CEO) decided he just wanted to sell the co ...

CED stereo is much more like Laserdisc analog audio than FM stereo - it has a second modulated FM carrier and a CX decoder. With boardcast FM left and right are multiplexed into one signal.

I don't have any connection with the site, but I can see about spreading it around a bit...

SJT-400 manual is here: http://www.dragons-lair-project.com/tech/ldguide/rca.asp

I've actually got that for Laserdiscs (using a much cheaper PCI capture card), and I'm pretty sure if I got a similar sample (or a suitably tapped CED player and disks) I could hack up the same for it ...

... (indignant words go here)

edit: a few unplayables???

In this case I would've thought a dealer would've known better, or told whoever stored them about it!

In any case, sad. Sad

Semi-related: what were the production yields?

This is what Tom did for the reverse - he basically regenerated the 220v/50hz power by going AC->DC->AC:

Ouch

http://www.dragons-lair-project.com/tech/pages/nfl.asp has the SJT400 service manual (the only free pdf CED manual I can find...)

And no ESD protection on the RCA jacks? Blah.

Totally. Even moreso since one of those players is an SJT-400 (even if it needs some work)!

I'd need to see a PAL player service manual, but I suspect the video FM modulation frequency is different.

In addition the color subcarrier is remodulated, and that is also likely different for PAL C ...

Agreed - service manuals are very useful for people wanting to dig into formats, etc. I've found Laserdisc service manuals rather useful myself, even for models I don't actually own! The only public ...

Sweet - I hadn't heard of any 2010-built players yet.

I'll have to look more closely at my (1999 Razz

) 919 soonish. One thing I remember noticing in the service manuals was that the 703/4's NR chip w ...

It's not that the DVL's are bad LD players, it's just that they could've been a lot better. And people often overcharge for them, since they were the last LD players made (I thought discontinuation w ...

Yeah - can't hold failed belts/rubber parts against any 30 year old home video equipment. A CED player is probably much easier to fix than a contemporary VCR. Even I could probably fix one... if one ...

Yipes! :(

Edit: The only vaguely local CL hit for CED's is this very confused, and long-lasting, listing: http://losangeles.craigslist.org/sgv/clt/4686591278.html

Yup! Even w/ the delays, if he was kept on as head of strategy, they would've made up the much smaller losses with the VHS tape licenses!

The only one I know of is the SJT400 manual here:

http://www.dragons-lair-project.com/tech/ldguide/rca.asp

Pretty useful for learning a bit more technical stuff about how CED works in general.

Ugh.

It's one thing if the reseller is a collector who knows what the item/player is and adds value to it first (new belts/tuning/good shipping for something bought local), but blind reselling is ann ...

I can't take it either (for multiple reasons, esp distance) but this looks good - properly stored disks and an SJT-400!

I'm on the LD side, but I wouldn't mind a nice CED setup if it fell in my lap, or preferably near it. (My housemate would have words, however Wink

)

Most LD rot comes from particular factories at ...
