Sony's forgotten ‘80s Picture Phone

Many people now carry a videophone in their pocket (whether they use this feature or not) - but it's been a long road getting here. This video looks at Sony's Face-to-Face - a $499 video picture-phone from the late 1980s.

I'll show the first version of a video on Patreon and often the feedback I get results in a video going through further revisions to improve it. e.g. Fix audio issues, clarify points, add extra footage or cut extraneous things out. The video that goes live on youtube is the final version.

There is actually a name for this technique of sending still television images rather slowly. It is called slow scan television or SSTV for short. Radio amateurs still use this technique to send images all over the world, although we use analogue mainly and colour these days, the idea is the same. The limited resolution used was primarily a limit of transmission time as a 320x240 image in full colour will take about two minutes to transmit using analogue signaling.

A similar Panasonic device was used during a series of segments on Late Night with David Letterman in 1988. Calvert DeForest (a regular on the show) was sent on a doomed goodwill tour from New York to the southern tip of South America, calling into the show to make phone reports every few days and sending a snap of himself using a Panasonic Picturephone. As they went further south, the picture quality gets worse and worse before finally not working at all and they just abandon the idea. You can find the video on KZbin by looking up "Letterman Pan-American Goodwill Tour 1988". Can't direct link in the comments for some reason. Worth a watch for the sheer situational comedy as well, but it gets a bit uncomfortable when they get to Nicaragua, have their car seized at the border and have to catch a rickety bus into the major city....and Calvert is reduced to begging Dave to let them come home!

[@nrdesign1991]

Looking at the waveform, it does seem to use FSK to transmit the settings and initialize the transmission, but uses ASK on a carrier frequency to transmit the image. The 64 grayscales might just be the result of the ADC on the receiving end. The setup for the full resolution "Normal" üictures will be a bit different timing-wise, but fundamentally the same.

My first thought was that it was going to be SSTV. Anyone who has pinged the ISS is quite familiar.

[@StarkRG]

It would be pretty silly of them to invent a new technology to do something identical to what already exists which suggests it probably is SSTV. That said this _is_ Sony who tended to have a "Not invented here" kind of corporate culture, so who knows.

[@GoSlash27]

Also an easter egg in Kerbal Space Program.

[@mrphlip]

I don't believe it's actual SSTV, as Wikipedia tells me SSTV is an FM signal, while this is AM...

[@MUSICLOVER72]

Great video and trip down memory lane 👍😎

[@IdahoFox]

It's interesting to see how many times the idea has been tried over the years. From proof-of-concept versions by Bell Labs in the 1930s when television itself was still fairly new to the public, to their later efforts with Picturephone in the 1960s, to this neat Sony effort in the 80s you show, and early webcams in the 90s and 2000s. Yet every time it seems like the public at large just isn't overly interested beyond the novelty of it. At least for the price that was frequently asked for the quality given. Smartphones and internet speeds certainly have helped bring the price way down, that's for sure. You do mention a good use for the tech being those who benefit from sign language and I agree that's an excellent market for video phone calls (2020 isolation stuff notwithstanding). But even as it's matured I think for most of us it's still a novelty with limited uses. Fascinating and cool, but still relatively niche. I think mainly because most still feel self-conscious about being seen on video. Whether that's a good or bad thing is certainly up for discussion.

well.

The audio of the picture being sent sounds very close to the same as what us hams use to send pictures over radio. Called slow scan TV.

[@m3snusteve]

Hi Robert I think you’re right sounds similar to Martin mode 2, or Scottie mode 2 using mmsstv. Been a long time since I’ve sent and received any slow scan tv pictures on 2m fm. 73s.

[@DarkFiber23]

That's immediately what I though of. :) I instinctively wanted to fire up MMSSTV to try to demodulate it. hahaha 73 de WU2F

[@imranahmad2733]

I had a similar problem with a 6" Sony pvm monitor, the geometry would get better when left to warm up after 30 minutes, I changed a couple of capacitors and that fixed it, but the service manuals made it easy to fault find, without them it's not too difficult but with them it's straight forward.

Yes, it can't be judged from today's standards standards of quality of photos. If you do it, you could also say that cameras on mobile phones of early 2000s were pretty useless. But instead many people used them and look where are we now with mobile phones cameras.

[@debrainwasher]

@Techmoan The keystone effect is probably caused by a dry electrolytic capacitor in the horizontal amplifier of the CRT. When e.g. the internal power supply voltage breaks down during each frame and recovers during the blanking intervals, such an effect is explainable.

[@bvapeldo]

Nice to see these again!! You could try them out at the PTT Museum in The Hague, The Netherlands, there were also telephones connected. The PTT Museum has unfortunately changed a lot the last years.

[@briebelbus1524]

I’m from the Netherlands and I’ve actually seen these Sony Devices in the PTT telecom store in full working demonstration back in the early 90-ies. There was also a payphone setup with video images. To see these units brings me back to my teens. Nice item.

Yes! Let us know how you go. That said, we are talking about analogue here, so before any decoding you need to demodulate the audio. GNU radio is made for stuff like this.

Judging by the way the direct capture of the video out looks, it sends it as analog, as in, it doesn't digitize anything. edit: I downloaded the file and looked at the waveform and spectrum, it certainly looks like amplitude modulation with carrier just below 2 khz

[@brucel.6078]

Ahhhhh.. early tech. Great stuff!!! Thanks!

[@BillOLDbergSucks]

This is just one of those innovations that was more of a novelty than something I could imagine have any practical uses. It's still cool to see though and I enjoyed your video covering this piece of history.

[@blacklion79]

Maybe, this picture distortion is "mechanical" problem - mirror/screen changed its position, as tube project image upward - and not electronic problem?

[@TehBIGrat]

These screens are used in alot of old Video Door-Phones / Video Intercoms. We service a few different brands and usually there are potentiometers for that adjustment.

[@somitomi]

I think it's an electronic problem, but it is related to the fact that the screen in these small CRTs is not perpendicular to the electron gun. So just like a projector set at an angle to the wall, some additional circuitry is needed to make the image rectangular and if that circuit fails, you get this. If I'm not mistaken, the screen is a phosphor coating on the inside surface of the glass envelope, so it's hard to imagine it moving without the CRT shattering entirely.

[@mjouwbuis]

@@somitomi the deflection yoke could have moved, btu I agree it's more likely to be a problem in the correction circuit.

Like humanoid robots or flying cars, video-phones are one of those ideas that people THINK they want, because its a sci-fi trope of "the future", but really, the practicalities mean they're next-to-useless, outside a few, niche cases.

[@ligius3]

Maybe it's just me and where I live, but I see people from the middle-east doing video calls in parks all the time, presumably talking to their families. So maybe it's a big thing there or just a cultural thing. I rarely see people from the west doing this in public, except perhaps for teenage girls. Maybe there's a stigma associated with it or perhaps people getting tired of video calls from work and not wanting to carry them over into their personal life.
