CED VideoDisc Development
 
Last Friday we were treated to some never-before-seen artifacts related to development of the CED VideoDisc format at RCA.

The New Jersey Antique Radio Club meets at Sarnoff Corporation in Princeton (the old RCA labs.) We're fortunate to be able to conduct our meetings at such an appropriate historic location. And we're blessed with such convenient access to the wonderful resources of the David Sarnoff Library archives.

Alex Magoun, director of the Library, cobbled together what was billed as the first-ever display of rare CED developmental artifacts from the Library's vaults.

Here's a video of this amazing presentation.

(Alex's presentation is item #12 on the list for "October 2007 Meeting" at the top of the page. You might also enjoy item #11 in which club member Rob Flory showed us an Iconoscope his grandfather made at the labs in 1932!)

That's pretty cool. I once owned a stereo CED player and a handful of discs. One of the local video stores even rented them. The audio was fantastic, the video wasn't all that much, about the same as VHS or early CX LD's.

I've been playing around with my pair of CED players this week. It's sad to think of the tremendous efforts that went into engineering these things, and that the whole project basically layed an egg. I guess that was the last great effort to come out of RCA?

Celt 10-17-2007 11:52 AM

Yeah, I think so. Although RCA continued making some very nice sets for several more years afterwards. VHS's ability to record is what killed the CED format and to face facts, RCA should have made the CED players better. Mine was prone to act goofy and skip. The cheap plastic lightweight platter didn't help things in that regard.

When I first opened up the players I thought the platter was cast metal, but then I saw otherwise. I just replaced the stylus advancing belt, which helped, but the better of my 2 units still skips every so often. I think my other one needs a drive belt. When things are working correctly they do put out a very decent picture (for their age.) Something I really like about these is that they are made in the USA. A real last-gasp.

I think laser disk is what really killed CED. It came out before CED and had a better picture with stereo sound (although early LDs aren't much better than CEDs). CED was obsolete before it came out, but they put too much money into it to just scrap the idea.

Celt 10-18-2007 01:34 PM

What was odd (at least around here) was that CED's were fairly common and even sold in some chain stores, whereas at the time, pre-recorded VHS, Beta and LD's were fairly scarce. It was at least 1982 before pre-recorded VHS became common around here (excluding of course the video rental stores). My first VHS deck was a Panasonic that recorded and played back Dolby Stereo on linear tracks. Shortly afterwards, VHS Stereo Hi-Fi came out. (Don't know why I felt the need to throw that out...I just did.) :D

Maybe it's my failing memory, but I seem to remember that the CED's were about $30-$40, where VHS was about $80 for prerecorded in the 81-82 timeframe. I remember the hoopla about Star Wars coming out on VHS for the unheard of price of $50, and then they were soon trumped by Top Gun for $30 because it had a Pepsi commercial on it, starting a problem all of its own. There were no LD's in the lower Mississippi Delta to speak of back then, it was entirely a VHS/CED market. LD was a science fiction expensive fantasy! VHS rentals were almost entirely what people down here did, and very very few actually bought movies on tape, expense being the issue. Is this familiar to anyone else or am I just senile?

I think CED movies may have been $25 and $30, which would be $5 less than comparable Laser Disc versions. Prerecorded movie tapes started at US$60 for the first group (all Beta) from Magnetic Video in about 1978. Later, they started to go up to $80 and eventually often $100, as the studios priced them for the rental stores since there was no revenue-sharing back then. Star Trek 2 was the first tape priced lower with consumer sales in mind, at US$39.95. The next low price was Raiders Of The Lost Ark at $29.95, and it included a commercial for the upcoming Indiana Jones And The Temple Of Doom, which was also on the Laser Disc, the only LD to ever get a commercial that I know of. These releases were in 1982-83, and low-priced tapes remained the exception all through the life of VHS and Beta. Top Gun in 1986 was notable as the first tape with a true non-related commercial, but the excuse was that it "allowed" the price to be $30 as ha1156w said. CED during its short life was always easier to find than Laser Discs, primarily because it was available from more manufacturers, starting with RCA of course. Laser Disc players were only made by Pioneer and Magnavox in those days. CED players were also less expensive, starting at US$300 if I remember right versus LD players at $600 or more, until Pioneer came up with a stripped-down $400 model.

Man, I forgot about the "low-priced" Raiders-- it may seem funny now, but that really did create a sensation of sorts at the time-- $29.95 was really cheap for a popular 'current' movie on videocasette at its time.

Chris is absolutely right about the relative prices of prerecorded videocasettes versus CEDs. CEDs were a lot less expensive. My parents got their first VCR in 1979 (a Toshiba Betamax-format unit), and prerecorded tapes were *very* expensive to buy. [Even blank tapes cost nearly $20] I remember us actually buying _The Muppet Movie_ on video when it came out (for Christmas 1980, perhaps..?); I think it was $89 or so. We must have watched that tape a zillion times though! :) I remember seeing _The Muppet Move_ on a newer VHS release in the late 1990's, but it somehow just wasn't the same without the cheezy Magnetic Video title 'fanfare' at the beginning. :)

I have a few Magnetic video Beta tapes. I remember that one of them was recorded out of alignment.

The reason for the skips and goofy action was impurities and dirt in and on the disc itself. They had a firmware mechanism for getting out of "locked grooves" but nothing to force it back to get the video skipped over if a piece of dirt kicked the needle forwards. I knew one of the guys developing this stuff, and he said that it wouldn't have been a big deal to write the code to do that, but some bozos in management wanted to freeze the design as is and ship it...

Celt 10-20-2007 11:04 PM

Well, that figures...

Eric H 10-20-2007 11:56 PM

I was working in an Audio/Video type store when these came out, I remember the hype and I remember the huge disappointment at the picture quality, especially compared to the Laser Discs which this store sold.

They had weird artifacts in the picture, maybe they improved later but it was a noticiable flaw at the time.

I wasn't aware that a software 'fix' was even considered or possible for that, but yeah, if you get an old well-used CED disc (like one that was originally a rental), they tend to skip all over the place-- especially the first time you play the disc after it has been sitting for a while.

Anyway, if your CED player skips badly and acts goofy the first time you play a particular disc-- but improves dramatically if you go back and start playing it again-- then the problem is dirt and dust stuck to the disc (a.k.a. the CED "video virus"). On the other hand, if your CED player skips a lot on all discs no matter what, then the problem is more likely that the stylus is worn.
