If you look close at the 17:34 mark, under the microscope you can read the RCA logo from the beginning of the movie. Its a mirror image but it clearly shows up!
The dark and light pattern you see around 20:00 is what an incrementing binary sequence (00000000, 00000001, 00000010, 00000011 ... 11111100 11111101 11111110 11111111) looks like as pixels. Digital encoding of the frame number in one line of the vertical blanking interval. Didn't some players read that code for random seek?
@@coyote_den There is nothing binary about this format. Pure analog. Those are test signals recorded in the first 21 lines, including closed captions and the analog macrovision signals ect. There will also be a multi burst and color bars, as well as aVIR reference and anything else in the VITS (Vertical Interval Test Signals) area of the NTSC frame.
I just picked up a 1982 RCA Selectavision CED player yesterday, and it works! I also got a 1981 Selectavision RCA VCR with optional remote control system too. So much woodgrain :D
Wow, what an awesome piece of technology that I've never even heard of. I really appreciate the in-depth look and explanation, the close-up shots of the disk were so cool. Such a strange chain of events that delayed the release of this for so long, and the fact it even released at all is definitely strange to think about, since it was so outdated by that point
There is a bunch of these on Ebay USA and there is one that comes with 16 movies but it sounds like it has the same issue as yours. The description reads- “This player works, takes the movie and plays. The color does fade and move, so repair may be necessary (possible new belt needed). Comes with all the movies shown and in original box with original styrofoam. Machine looks to be in almost unused condition. Please ask all questions before buying.”
It's junk just like this one. Worth 0 dollars. Just like the guy on Facebook now that was asking 75 for a broken DAT. Has had no bites so he has reduced to 50. Last broken DAT I bought was 10.00
We bought a CED player in 1982.Looks just like that one. Have a few dozen discs. The player stopped working a couple years ago. I was trying to copy to DVD. (They were specially edited for CED Gimme Shelter and Queen Greatest Flix). CED was what my father chose over Laserdisc. I noticed that some of the discs would skip a lot. I guess over the years dust got in or something. (60 minutes max per side) Believe it or not, we never replaced the Stylus. But we only used it for a couple years constantly until we got a VCR.
It's a common issue with the format and can occur for a multitude of reasons, including if the disc hadn't been played in a while. One of the things that can happen is that the silicone lubricant that was applied to the disc can form a smooth and glassy surface that the stylus must cut through to the groove, and sometimes it can't do that on the first run. Therefore, a conditioning play must be run before actually playing the disc for viewing ... and sometimes you may have to run it through more than once before you can bring down the frequency of skipping to a minimum. It's kind of amazing that the format even worked at all.
Its actually not that bad. I have seen far worse, namely any TV shop from the 1960s through the 2000s. There is a reason shops had a sign that said employees only. LOL. They all looked like this. Even the benches at Sony were cluttered.
I had laserdisk and had to drive a long way to rent movies. So i would go to a store that rented them once a week and get about 10 movies at a time. Store owners name was Jack Frost. He was a big jazz fan and had all the jazz laserdisk. I remember him telling me that the rippingtons were going to play in Vancouver so i got tickets. When he closed his store he sold me a bunch of his concert disks which i still have. Some 8" and the rest 12" laser.
Too bad that there is not a way to fix the bearings for as how rare that machine is would be great to have it in a fully working order even tho it is just a shelf piece to look at or for in a museum .... I know time wise it is not feasable to try to fix the bearings as you wont make any money off it but sure would be great to see it really resotored some how in a fully working unit... Good video Dave
I wonder if you can drill it out and insert a nylon drill bushing in there. I did that with a dishwasher pump and it lasted 2 years of daily use, which was the same as the factory pump motor regardless.
$77. The first thing out of my mouth was totally inappropriate for this channel, but it started with an "F" and ended with the word for eternal fire and brimstone. Also, I agree, the shipping totally outweighs the repair cost. You might want to consider only doing stuff locally in Canada, unless your USA counterparts want to actually pay the postage, of course.
I found one of these for $15 at a local thrift store with five discs. Mine's the Zenith clone. Said to myself, "I'm the only one in this store right now who knows what that is, and it's coming home with me." Somebody thought it was an audio record player and had some religious record stuck in it. Removed the audio record and it then worked perfectly.
I have one of those and it blinks L when you plug it in and it’s in the off position, so idk what’s wrong with it, that’s what it does when it’s off, when you put it in the off position, it blinks the L(Loading)…..so any help would be nice
I think these things are cool even though they are old, I just wanted mine to work and I have two ced discs to go with it, any suggestions would be greatly appreciated……I want to figure out how to fix mine…….I got an old tv that I can connect it to, so I would like to know why mine blinks L when in the off position, I haven’t put any discs in mine so even try it…..I want to replace that stylus, well the whole plastic thing but I want to fix the L problem…….
Your statements at the beginning of this video were completely untrue. RCA did not recall all the CED players, and did not burn all the discs. Why do you make these untrue statements? Clearly, you were the wrong person to bring this player to for repairs.
Actually they did in Canada. I worked at a large RCA dealer and they took them all away. And the discs. Now perhaps they blew them out in other markets all I remember is we shipped them all back. Had to box up the unsold discs and players and sent them all back for credit. What RCA did with them i don't know. Never fixed any because nobody was dumb enough to buy them. We actually rented players and discs out when they were around.
Technology Connections did a great video on the history on this format and has done lots of videos about the history and development of lots of different types of media. Definitely a channel worth looking at if you are into old stuff like this.
Who do I see about getting that hour back? LOL...I wish the video was longer...listening to you drone on about dead video technology pushes all of my buttons. If you had a matched set of screwdrivers or a clean workbench you'd lose some of your charm. Thanks for bringing some much needed meaning to my life...really.
I was actually hoping that this was going to be repairable and that it would have been just lubricating and so forth or that it was a disc that was causing the problem and I actually thought that that's what the issue was right to the end. I'd actually finished the video and left it on a note that I thought it was the disc and just before going to put the thing together I just happened to by accident push down on that spindle while it was running and the picture cleared and it was like holy crap it's the platter it's the bearing! I had suspected that the bearing might have been causing the problem just from the way that it seemed to resonate but I wasn't sure because the disc looking like it had a warp to it certainly could cause the same issue but it actually wasn't the desk it was the platter itself. Now I'm sure some of the old texts that worked on these things briefly in the early 1980s were probably laughing now knowing exactly what it was but myself not have had the privilege of ever working on any because I think the shop that I worked at sold a total of 2, and I never got to work on either of them. We sold one replacement stylus to one fellow that was gung-ho about the technology. Here's a kicker for you the shop had a break in we caught it all on video in 1984. The crooks grabbed about 50 VCRs they did not take one CED disk player. I'm kicking myself now because when RCA took all the units back they offered us a player at $25 and movies at $2 each when they were recalling them that was for the current movies that were already out that we had in the store and none of us took them up on that offer so they took them all away. I should have had the foresight that 40 years down the road this would be a highly collectible item and having one that was brand new in the box might be worth something.
The CED format was released in 1981. Player production terminated in 1984, owing to sales of players being well below projections; no point in making more players when you have a surplus. Disc production continued until 1986, followed by the acquisition and breakup of the RCA Corporation by General Electric. CED wasn't the only factor to cause RCA's downfall, but it was a major contributor to its failure as a company, considering how much money was lost because of the venture. That said, a big issue with RCA was that it basically had no leadership for almost two decades up to the point where it went under, so the company was all over the place with its diversification outside of its core business as well as mismanagement. It basically all started when David Sarnoff retired from the company, leaving the reins to his son, Robert Sarnoff ... and things went downhill from there.
That happens more often than you can imagine. Electronic parts shop. Original founder passed to his son when he retired and he ran the business for 40 years passing it to his son who promptly closed the business.
I would like to add: our CED player came with a free disc. On Golden Pond. We never seen that movie before, I was skeptical it would be any good, because it was free. We actually loved it. Our local tv and appliance store sold us a new CED player, but it didn't work out of the box. So they exchanged it for the store Demo player. July 31, 1982. What memories! Yes, I remember dates . Not of everything, just important things.
movies on a vinyl, that's new. or should i say old? Thinking about the "invalid traffic" on channel, i hope youtube doesn't see it as such when i start a video on thursday evening, pause it and resume on friday. when i do that, youtube reloads the video
There are actually some NOS stylus cartridges available on eBay. Though of course they are absurdly priced. Those microscope shots of the disc were really cool to see. Thanks for that!
I actually use mine. Not a lot, every few weeks I watch a disc. Pain in the backside to money wise to find one and get it to Australia, and then find somebody to service it. Have about 30 movies I think. Model I think is SGT-250. I’m on the lookout for a VHD player now….
If I remember right, the stylus was diamond made in a special lapping machine then had a metal contact plated/deposited on the back of it. That formed one plate of the capacitor, then the disc was a multilayer deal where the core was conductive (the second plate) and then the shell (thus the dielectric) was molded atop with the information. I lived in a town (Lancaster PA) with a pretty big RCA plant and R&D effort. That company tossed out great ideas left and right. Heatpipes were an invention of that plant - get rid of it, they said, no money in it. So the managers bought the patent and got rich. CED was something they kept. If it had come out ten years earlier when they were futzing with it, it would've been great, or if they went with their prototype tape system instead, they'd have been sitting pretty. But no. Bad management.
I think the diamond stylus was supposed to have been profiled into something resembling a keel shape profile. The metal contact on the diamond was probably formed using chemical vapour deposition and was connected to the rest of the stylus assembly and on to the rest of the player using a trailing titanium electrode as far as I have been able to glean through research.
It's too bad RCA didn't discount the players, discs, and stylus long enough to get them off the showroom floor to people who didn't care if they just had a unit that only played discs.
They did. The players dropped to 99.00 to clear them out. A couple of them sold, but most went back. Boxing day they dropped to 49.00 and any that didn't sell were shipped back.
The music background from RCA Selectavision VideoDiscs logo is from Isao Tomita- Pictures at an Exhibition, and I didn't know that. It's ironic that it was produced by RCA Victor Records.
RCA bet the farm on this inexpensive, 70s tech and lost. What people really wanted was to record their favorite shows and watch them later. That's something that NTSC 3 will finally put an end to. For over 40 years, people have been legally pirating TV. That's an oxymoron if I ever heard one. I honestly don't even know why they're even bothering with keeping TV alive when video streaming gives IP owners full control over their content. I mean, you need Internet for all encrypted TV content, and it will likely pull the content off the Internet, anyway. I don't even watch TV except with severe weather rips up my home state of Oklahoma, and you'll likely need a subscription for that, too. Welcome to the dystopia of the future!
Next will be data usage fees by ISP. The more you watch the more you pay. Oh wait, thats already here. Pay an extra 20 for unlimited data. I read on C-Net last month that AT&T is going to shart charging 10.00 per month for the ability to skip commercials on recorded content. Netwitz and anazoon and disnay and already charging for commercial free viewing as is youboob.
So I acquired one of these a while back. I did not realize this was a completely different format. I tried shoving a laser disc in the thing. I took it apart and was like WTH! I thought laser disk was optical what’s this stylus for? Then I found out RCA was trying to break in to the market with this crap. I did find a video disk and it did play okay but with horrible picture and sound. Sold it at yard sale and never want another one.
I remember these. When I was a kid in a small town we used to rent the machines and the movies before we got a top loading Panasonic VHS machine on NYE 1983. My aunt and uncle actually owned one of these machines (a Toshiba), probably the worst investment they ever made lol.
As the old proverb goes, the invention of the light bulb was not a result of infinite refinement of the candle. Well, what RCA did with CED proved the dangers of failing to learn from the history. RCA engineers simply took the LP record format and iterated it to barely idiot-proof fragile product, while at the same time making every effort (and a lot of compromises along the way) to slash the player's price tag to the bottom. This is the reason for the bare-bone analogue approach for the CED recording, where the entire TV signal was directly etched to the surface of the disk, negating the need for any extra circuit logic, even for a simple aspect as the vertical blanking signal. This race to the bottom in the end is took the whole company with down, given the fact that RCA had to even subcontract the manufacturing of their first VCR machines -- to expensive and complicated to do it themselves apparently.
The players were well built and easy to service. In the early 00s I had a 400 model with similar problems. But the format sucked, I call it skip-a-rama bc it skipped so much. LD was superior.
I bought this unit at the thrift store a in November of last year. it was a player cost $9 it was a great deal not a steal. the stylus is intact when I try look for a outlet to see the player function works. but sure enough the power switch mode the light flashes see L. it stand for load disc on there. I bought the thing. took it home had some couple video discs from the previous thrift store to try it out test it see it's works. it works perfect. I just bought some couple of CED titles online they were National Geographic and Gloria both sealed copies. I was planning to get a few more RCA video disk movies they have. I used to have this I was so young I remember it was a Sears brand a clone version of the player like this. my parents bought it the first disc we watched was Star Trek the motion picture. the last disc my parents bought Popeye in stereo a blue caddy sleeve. those are my childhood memories I remember. now it's in my bookshelf cabinet for the rest of my vintage video disc player collections. it's so rare too own.
@@12voltvids wow that's cool. I have a laser disc player and another DVD and laser disc player and the Blu-ray player. also I have DVD recorder player and VCR combo player as well. they're all both from pioneer. 👍
I enjoyed your very much video. I'm in the UK. I have one of these machines and 20 or so discs. It's a little simpler by design. At one time I had two machines and one would be a lot worse at playing discs, I think the stylus was wearing out on it. Also some of the CED discs are in a shocking state, the oil on them I guess gets sticky and I found that one of my discs needed repeated plays to settle down and behave itself! When they skip it is quite funny to watch. These players are nice in that they remind us of times gone by! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-_zGbT6GMd1c.html
I still Have One just Like this Player and A pioneer that Takes that Big CD looking type disc, My RCA is This type Of caddy Disc, Both players Been in the Family since new and Still work All that was needed is A bit of Cleaning ETC from time to time, yet i'm looking for more Movies for the Pioneer Lazer disc player, i have 10 of The Movies for my CED player, Just seems here both are rare or hard to find now.
@@12voltvids I only Got one for mine , its A cartoon one, The other RCA i have about 12 Disc for that one .I like to keep anything thats an odd format myself too, but here Can't find Any at all no place, I live in NY state, but seems noe many Disc or even players here either. The 2 Players i had been in the Family for Qiute a number of years, since no one else wanted them i took the Players home here with me.
There is a video on youtube titled "How to Service a F/G Model CED Videodisc Player" (Credit recognition: Josh Gibson ) with examples on how to remove the platter and some of the deeper consepts of its operation . the platter does set down on a braking surface in its lowered position.. dont know if examples like that will be any help but you can look at it if you wish. .
Yes I know. The lever below it raises and lowers it. The problem with this one is the bearing shown at the 49:37 point when I oiled it is worn. That plastic base is the bearing that the platter fits into. It's just worn out. When I pressed down on the disk centering hub i could feel it wandering around. This is what happens in belt drive equipment. There is the constant pull in the direction of the drive motor by the belt that wears the bearing more on one side then the other.
@@12voltvids You also have two sleeve bearings that interact with the turntable shaft that need to be lubricated. You can't get to those without removing the platter. And if those sleeve bearings are dry, they will induce drag.
In the early eighties I wanted one of these discs players. I voraciously read consumer hi-fi and video magazines opting to go with LaserDisc for the more superior sound and picture.. Not that I was smart. Far from it. LaserDisc too was a plagued format. My Magnavox player did not handle warped discs well...and most rented LaserDiscs would become warped likely from users hot cars and other poor handling. To buy discs was still expensive enough that it didn't make sense for me to buy a movie I'd only want to watch once or twice. Matsushita and Pioneer lost a lot of jack pushing the LD format which ultimately failed too.. At the time most folks chose VHS over these discs. That was actually being smart. Outside of the novelty of owning new tech (which wore off fast) the benefits of early optical discs were few if at all. Good nostalgia here of a time when the race for the future of home video was a hot sector of the consumer electronics market. I enjoyed your video and could clearly see the built-in reasons these players were what Steve Jobs later referred to Blu-Ray as "a bag of hurt", LOL.. Blu-Ray was (and actually still is w/ 4K) like a Porsche 911 opposed to these early optical video formats which were more like the East German Trabant comparatively speaking.
Laserdisk was a success this was not a laserdisk. It used a stylus not a laser. This was a flop but rca had to bring it to market to fail because they spent so much over 550 million in 1960s abd 70s dollars developing it over 17 years.
Had one of these in college, they were in several video rental places, when VHS took over all the stores sold the rental players for $75 I picked up one and bought a bunch of discs for $5 each till nobody wanted them then they were $2 still have them all Player still works. I thought it was fine at the time as VHS players were way more money. But i hated flipping disc in the middle of the movie. And some of the long movies had 2 discs and you have to flip it twice. I am not so sure it was the same quality as VHS i think it was better, but no way to record. I won't say it was leaps and bounds better, in fact i doubt there was much difference. I got all mine at a RCA store.. The funny thing is that the store is still open 40 years later but it's not RCA anymore.
I actually HAD disks and players in both formats. Being a CB radio junkie i met a lot of pickers that had everything you could think of electronic. I got players from them and at an antique store in area i found a both that had several disk in both formats. Im just extremely sad that GF at the time jacked me for them and lots of CB radio equipment i had collected. That horrid ho!!
I found the same unit years ago and it had the same issue. The stylus would not advance in playback. I took the cover off and cleaned the gears where the wires were cut and that fixed it. Just grime from sitting all those years. I have about 2 stacks of movies about 3 ft tall collecting dust.
My thoughts on the disk. Back in the day the original owner of this unit bought it to watch quality action movies. Well that was all good but the owner had a kid. They bought this movie for the kid. By knowing just the parental thing, and kids, this movie has been played over and over. And over and over and over. LOL.
i remember growing up with these, my dad had a huge collection of the CED discs, they where cheap at the time and VHS and BETA was super expensive, he ended up selling it because VHS got cheaper later on, then years later he found a machine in goodwill (different than the one your showing) and gave it to me to fix all it needed was a drive belt, and i fixed it, i still have 1 disc the original 1953 the war of the worlds, but my stupid dad sold the machine among many other of my collectible stuff when moving, i was young at the time. and i got so pissed at him. no, actually a slight warp disc will play just fine the needle is not supposed to move like that. the needle is the problem it appears to be missing the back support wire (similar to the electrode wire) or rubber which holds it steady. and no, holding the center isnt the problem, not a bearing issue, your body is grounded which is how the disc operates low voltage electricity flows through the disc to the needle. there is a grounding brush on the platter shaft similar to the grounding brush on a vcr head drum. it could be clogged or missing.
No you can feel the platter shaking. There is not a viktage flowing through the disk. The dept of the Grove changes which changes the capacitence of the stylus. It rides in a totally smooth groove with noblateral or vertical movement. The signal is pressed in below the actual groove the stylus rides in. It reads the information below the groove. When i presses down on the spindle it actually removed contact from the disc. It was stopping the wobble that allowed the disc to play. Soon as I released the wobble returned.
@@12voltvids CED discs are made of conductive pvc with use of carbon a small voltage goes through the disc, to ground, its a grounding issue, this is causing the color issue, trust me, also i forgot to mention watching your video made me break out my RCA CED player SJT 300 which i bought years ago and replaced the stylus, found on ebay, my player has stereo and rca component outputs. along with the typical coax. i still have the remote. brings back soo much memories. someday id like to get more CEDs to collect.
@@jr-pl9kj Yes i kbow. I remember seeing a documentary on it. Forms a capacitor the disc being a grounded plate and tip of the stylus the other plate. Capatence changes. I never serviced this was the first one i have looked at. Have no idea what goes wrong. The disk did have tons of wobble. It wasnt just pushing down on the spindle but pull it slightly to atop the wobble.
@@12voltvids the wobbling thing, sounds like the platter needs oiling usually done under a bolt accessible under the machine in the center, i hope my comments can help you out. let me (or us viewers) know how it goes. there are service manuals for these CED machines available online for free in pdf format. heres a link manuals.lddb.com/CED_Players/RCA-SFT-100_EN__Service_Manual_Scan.pdf
I have two ced players and I swapped the needle out on one of them and I have one that wants to play but it makes a noise but it wants to work, it powers up but no picture, how can I swap parts on one player to another so I can have one working player…..
I bought one from eBay and in the ad the guy said it works good and it came with ced discs and I connected it to the old crt tv that I have and I put it into the load position and nothing, I put a disc in and nothing came on the screen and then after that I took out the disc and then there was no power, I plugged it into another outlet and got nothing, so idk what went wrong with it, so I got another one from Craigslist and that’s the one that will power up but it wants to work, I swapped out the needles but it makes a noise so idk if it’s a belt or what, I want to swap out the parts out of the one that didn’t power up, can anyone help me with this???
A friend of mine back in the day bought one of these. He actually joined a mail out club to gets his discs. When the tech went belly up the club sent him a list of their inventory. He was asked to tick 50 titles and they would send them for free. Indeed, a few weeks later he received a big box of 50 discs. I can definitely remember An American Werewolf In London and maybe even Debbie Does Dallas? Such fun!
Don't think there was ever any porn released. Laserdisk yes, because 3rd party manufactures released them but rca controlled 100% disk manufacturing and i doubt they would get involved with that. Too high risk of backlash.
I had the hitachi version I bought it at a local auction house . It worked out was schechy on some discs I sold it one I had gotten fed up with the films I got with it .
hi picked 2 stereo decks up some time ago i was lucky the decks worked ok the thing is the discs had heavy wear because the one who had the deck used it as a music player it's the kind of deck you could show of on here i don't have alot of disc's what you said on here they are money pits
I worked for an RCA dealer and there were continuous complaints of skipping. They had model numbers SFT-xxx, SGT-xxx and jumped to SJT-xxx. They probably skipped a model number starting with SHT because it was a piece of you know what!!! The shop display demo disc skipped like crazy. What a way to sell a product!!! 149000 was what RCA called a QT (Quick Turnover ) part. Stylus assembly. Actually the motor in this unit is only a 2 pole motor (not a 4 pole). Again. Cost cutting.
My dad bought a CED player for my Grandma when they came out, I inherited it when Grandma died in the late '80's. It was a mono player, but we had one stereo disc: A live stage performance from the cast of the Fame! TV series. Some of the movies we had were The Wizard of Oz, Trading Places, Oklahoma, On Golden Pond and Seven Brides for Seven Brothers. It had a mechanical loading problem when I got it, and I fixed that. I enjoyed it well into to the early 2000's, but got rid of it when the stylus got too worn to play properly. I wish I still I had it for the "Museum Factor". I forgot the model number, but it was most likely a RCA SJT-090.
I have two working players, I got hold of the new belts, and changed them out. But It Is the Stylus that Is no longer available. So I have to keep swapping It between the two, till I can get two new ones. If Anyone has any idea where to get these from. They are both UK Pal Stereo machines. GEC McMICHAEL V5000H CED video disc player is the same model as the Hitachi VIP201P
@@12voltvidsThanks. I have looked on there, but none for my model. When You change out the other belts. Be very careful with the Plastic parts. as these are very brittle. I used a Hair dryer to sofen It first. When Is the second half of this one going up?.
Funny bit of info … I got one of these … fixed it (belts were gummed up and gears were cracked) Going through it …I thought I had a speed problem… audio was a tad fast… Got frustrated because I could not find any speed adjustments. Well, I was using The Empire Strikes Back as my test disk. Turns out Lucasfilm prohibited the release on 2 disks.. they got around it by speeding it up 😆😆😆😆 So don’t use Empire Strikes Back as a test disk !!!! 😂
"A New Hope" was also time-compressed to make it fit on one disc, so that's another "Star Wars" movie where the sound pitch is higher than normal because the film-to-video transfer was faster than normal. "Return of the Jedi" is a two disc release, so no time-compression was used. But it came out relatively late in the CED format's life, so that's a relatively rare pressing whereas the first two movies are common. The SFT/SGT belt drive models used magnetic sync plates for speed adjustments while all other CED player models were quartz-locked and no adjustments are possible. But if you are getting steady color video, your turntable speed is right on. Variations in turntable speed will directly affect video stability, and one of the first things you'll lose pretty much immediately if the speed is off even by the slightest is the color.
There use to be a place that rented these when I was kid (yes I'm old) this was my first experience watching the star wars trilogy. A side story about that place that rented only CEDs it burnt down and after reading about the format flopping years later I'm wondering if that fire was no accident.
I have a suggestion: you may want to drop the audio level of your intros music by 12dB when talking over them. Makes it easier to hear what your saying, I'm straining some times. This isn't negative criticism, I enjoy watching all your videos. It's just some times your mic is either too quietly mixed or too hot.
I actually do balance my audio level while I'm doing the production and I'm going to stay with headphones and I hear my voice clear as a bell but the audio is typically 10 to 12 DB below the voice over.
Also, the picture of the dog listening to a phonograph under the RCA logo, wasn't that originally "His Master's Voice"? Or, did RCA either own or bought it out?
Hello Dave , i was born in 73 portugal . I use to watch the muppets show wen i was a kid , the best memories of my childwood ! I Just want too adress something , i love the content of your channel your knowledge in old tech its amazing , big fan , lots of respect .

A magnetic video disk format also existed, that one was like a floppy disk. 50:39 - 2-pole; probably not even a sync motor, just an induction type shaded pole motor.
Definitely not a synchronous motor. The power line (and the drive belt) don't provide enough stability for color video. I'm sure it's an induction motor running on varying voltage, that allows the circuitry to trim the platter speed to exactly the required 60/n/1.001.
That your colour varies on playback is due to the variations in speed. Might be the drive belt or the platter's magnetism is lacking. And don't try to adjust those front switches. Thanks for the video.
With the sled motor disconnected, it could still play the first few seconds before skipping back because there is an "arm stretcher" transducer that does the fine positioning of the stylus. If you were digging deeper into it I'd check that next.
As far as I remember reading, the stylus on a CED player was indeed diamond but had a trailing titanium electrode that was somehow bonded to the back of the diamond to provide the electrical and capacitive coupling which fed the signal to the rest of the player.
Yes you can see the tiny tip. I couldn't see that in prevue resolution that shows on the screen during editing, but it was certainly visible when rendered at full resolution.
I have a selectavision in the garage. I don’t have any disks though😞. Had these not been delayed so long from release they would have been ahead of their time. They were developed in the early 1960s but by the time they got released there was already the other technologies you mentioned and they were much better quality and no contact with the disc.
Certainly another strike against this format was having to turn the disc over halfway through a movie, using the disc's caddy, ala side 1 and side 2 of a record.
That pot is just providing feedback to the sled servo and it's working. The failure on this one as shown at the end is the main bearing for the platter. Its plastic, go figure.
A great idea poorly executed and took 20 years to develop. and you are right, it bankrupted RCA. My brother bought one new and it never really worked well right from the get go. issues with playback even with brand new disks. toward the end they just had to get something out and rushed in no t yet ready to market. Designed by Committee and with teams not talking to each other.
My parents had one. Video quality was superior to VHS. The only problem was like a audio record at the time, if you got dust on the disc, the video would skip.
Considering the resolution was the same as VHS you can't say with a straight face it was superrior. Now laserdisk, now you are talking a superrior picture and sound.
The yield rates for early laserdisc pressing at the DiscoVision plant near LA were awful, apparently in the single digits at the beginning. So if you bought a disc you were also paying for all the ones they threw out. I think it took Pioneer buying the plant and retooling it to get them up to acceptable levels. The stylii for these machines are also quite sophisticated and complex to make; apparently when they killed the format RCA made enough spares to satisfy their projected demand for replacements from existing machines and then decommissioned the tooling (I wonder how long you could get them from RCA). And I've actually seen used CED movies for sale at BMV Books in Toronto multiple times (somebody bought them, and they didn't sit in the store for months either).
They are bringing these back to replace blurays. Bluray can be copied to easily. Just like with CDs. That's why CDs really disappeared. The music industry doesn't want you to own cds.
The music industry loves to sell you physical CD. It's just the young folks are dumb as a box of hammers and pays 15 bucks a month to lease music. And then a expensive data plan to listen on their phone.
had one of these, ages ago, got it at a garage sale 1985 or so, with 20 movies, I don't remember paying much for all of it, it worked, then died, a miserable death a few months later, I do admit, the intro start up circle/logo music etc is cool , I also made for the time, wall art with the disc covers for some of the movies, definitely a financial blunder from RCA, Coleco would do the same in some ways with it's horrible, ill fated Coleco Adam Family Computer,
@@12voltvids I agree, way overpriced, for what they are, a electronic oddity,that would be neat to have today, but one would have to fall into my lap for nothing, for me to actually want it, I just don't see the value, typical of Ebay sellers though where everything is literally rare, and therefore valuable in their eyes
I was maybe 10 years old. My dad lived with a friend of his. This friend was way up into the players and picture quality. He had the VHS, beta, AND the video disk player. I remember going to the Curtis Mathis store to rent movies. You would flip through those things like you were shopping for an audio record. I remember being all up into a movie and all a sudden 'Please Flip the Disk'. They had full sized satellite dish. One weekend he would go outside and crank a handle to change satellites, the next week he had a rotor. What the hell is a line doubler? LOL Good video. PS So uses constant velocity and not linear velocity like digital, got it.
There's another channel that did a deep dive on the CED format and development (not posting the exact name out of respect for your channel). Quick summary is that it was an ambitious product that took way too long to develop and your comments about Videotape killing it was very true. (Edit - obviously I wrote this before getting to the end as you mention this)
I actually replaced the cartridge on one of those machines , pretty nice picture! That was one of the problems with it, the cartridge didn't last long , disc would wear pretty fast!
My neighbor's dad bought a player and a few disks. One night we watched a movie over there. It was fine as long as you didn't touch the player or stomp much. It would start skipping and go insane.
i had a chance to buy one of these players with a stack of movies a couple of years ago and i never seen or heard of the format. I kind of wish i had picked it up but then why bother if i had a good laser disc and vhs player. still pretty neat look into how this format operates.
My uncle had one of these and it has so many memories attached to it i would watch movies on it when i stayed over with them idk maybe thats some of the early beginnings with my fascination with electronics.
Bought mine in the early eighties from Radio Shack under the Realistic brand. The discs were around 30 bucks with limited selection. This was a very finicky system as skipping would occur frequently. The first selection I purchased was a 2 disc set of the Godfather....
It was terrible. Should never have gone to market. I can think of a few other things that should never have gone to market too. VHS being one. Betamax was so much better and the recording time thing could have been extended like it ended up being. Had everyone got on board there would have been 1 format and that would have been better for everyone. Smaller tape better quality. Then there was HD DVD which also should never have happened. It basically took down Toshiba like the ced system did to RCA. Sony on the other hand did extremely well with beta. Notice I didn't say betamax, as it was their betacam format that ruled broadcast and professional production for the life cycle of video tape. It used the same parts as the betamax system used.. same pinch roller and tape threading system, same size drum. Just a different video head and different video processing and of course a much faster tape speeds. 2 sizes of cassette. A small cassette exactly the same as the betamax used and a larger cassette for longer record times.
@@12voltvids "I can think of a few other things that should never have gone to market too. VHS being one." Yeah, right. "Betamax was so much better" It wasn't better at all, let alone "so much better." "and the recording time thing could have been extended like it ended up being." It could never match VHS's recording time because its tape cartridge was smaller, so for a given thickness of tape, VHS cartridges could always fit a lot more of it, and no matter how slow they made their linear speed, VHS manufacturers could always make theirs just as slow. L-830 was the longest Betamax tape and it could record 5 hours at its slowest recording speed (βIII). That's not even as long as VHS's recording time of 6 hours on a _standard_ T-120 tape at its slowest recording speed (EP), and with a T-120 you're not stuck with the fragile, ultra-thin tape that an L-830 uses. And if you wanted to use fragile, ultra-thin tape with VHS you could go all the way up to a T-240 for 12 hours of recording time at EP speed. "Sony on the other hand did extremely well with beta." No, they didn't. Betamax was a failure and Betacam was only a success in the professional market, which is small potatoes compared to the consumer market. I have three VHS VCRs from the 1980s (1983, 1985, and 1988) that still work fine, so there's nothing inherently wrong with the fundamental design in terms of reliability. Also, I've made recordings on my highest-end VCR (JVC HR-D566U with new Maxell HGX-Gold T-120 tapes at SP speed) that look almost as good as the DVD or BD that I recorded from (when viewed at the same distance, on the same CRT TV, and over the same composite video connection), so there's nothing inherently wrong with the picture quality. Betamax _might_ be able to produce slightly better picture quality at βI speed, but then I couldn't even fit a whole movie onto a standard L-500 tape, nor even an L-750 tape for movies longer than 90 minutes, and most Betamax VCRs didn't even have the option to record at βI speed to begin with. Sony shot themselves in the foot with that tiny tape cartridge, and them being a far less open format than VHS didn't help matters either. Your idea that a wildly successful video format that dominated the consumer market for two full decades (1980s and 1990s) and parts of two other decades (1970s and 2000s), and for which most people had no complaints back then, never should have gone to market makes no sense whatsoever.
Sony could have dropped the speed so the l750 tape could record 6 hours. They chose not to have an even slower speed. Sony put their engineering efforts into betacam. Cost wise it wasn't that much more to make a betacam deck and with them selling for 12,000 to 80,000 that was a real moneymaker for Sony. They might not of sold millions like home video but there also wasn't 30 different companies making them. There was Sony and Ampex making betacam and all the other flavours of betacam. Digibeta, sx, HD beta. They sold 10s or thousands to tv stations and production companies world wide and with a high profit margin and high profit on maintenance and parts. Make no mistake Sony was laughing all the way to the bank and it started as betamax. Betacam uses the same parts. Betacam SP used a different drum due to metal tape but regular betacam they just added 2 more heads for the component chroma and they were golden.
@@12voltvids "Sony could have dropped the speed so the l750 tape could record 6 hours." Again, no matter what they did to increase recording time, they would always be behind VHS. Plus, with an L-750 you get thinner-than-standard tape. That same thinner-than-standard tape for VHS is in a T-160, which gives you up to 8 hours of recording time. "Cost wise it wasn't that much more to make a betacam deck and with them selling for 12,000 to 80,000 that was a real moneymaker for Sony." Sure it made them money, but like I said, small potatoes compared to the consumer market, even at the exorbitant prices for each unit. For example, there are about 1,750 TV stations in the US (most of their customers were TV stations), but there are about 131 million households. Thousands or tens of thousands vs. hundreds of millions is a drastic difference. "They might not of sold millions like home video but there also wasn't 30 different companies making them." JVC got a piece of the pie for every VHS VCR sold, not just on the basic VHS technology, but also on the use of its logo, and for licensing Hi-Fi stereo technology and its logo, and for licensing HQ technology and its logo. Also, there weren't 30 different companies making them. It was more like six Japanese companies three Korean companies (LG/Goldstar, Samsung, and Daewoo). Ones branded GE, RCA, Zenith, Magnavox, Sylvania, etc., weren't actually made by those companies. They were rebranded Panasonics, LG/Goldstars, Samsungs, etc. "Make no mistake Sony was laughing all the way to the bank" They would have traded it in an instant for the success that VHS had in the consumer market for decades.
