This is not SSTV. This is directly synthesizing a frequency spectrum using images as the volume for each spectrum chunk. This is a rudimentary wideband method. Very cool, though.
SSTV uses frequency-shift keying (a single tone shifted around higher and lower) to represent the video signal in much the same format as composite video on your VCR, only much slower. Each scanline is synced with a low sync pulse. Each frame has a "header" and "footer" area. Modern modes even support color images. :)
Try searching for SSTV, Amateur Radio has been doing stuff like this for years. We send Images, Text and Morse all using sound, this could be easier to record to Tape. Try MMSSTV or HRD (HAM Radio Deluxe) if you want to try decoding most of the stuff. I'm sure you can record this to Tape in the same way although you will need a Radio Licence to transmit.
So like in the beginning I'm laughing "She's just a modem", but this signal never stops being analog really, right? just like old school TV wasn't digital?
whats the program you used to encode the picture to analog audio signal and what softare did you use to get it back from audio to picture, i want to try this at home.
could it ry this with an ordinary cassette recorder, please could you do a quick video or inbox message about how you did this i would like to try this.
To easily decode these kind of messages google for "Coagula Light". Though when it comes to transmitting images over audio I prefer plain old SSTV (best software for it as far as I know is MMSSTV). Supports not only colored images, but using some high quality settings you can actually transmit them in very good quality too (though the clip will be very long, almost 5 minutes if you use the highest settings)
Not sure of the point of this. I used to have ZX Spectrum which basically loaded a program which may or may not have included a picture. That was some years ago. Are we going backwards?
@LiviuJETIX It's a telebug, a cartoon that aired in the early 80 about robots with TVs for heads, you're probably not old enough to remember that series.
A similar method was how my dad used cassettes to record the 'beeps' from the (If I remember it right) NOAA weather sattelites: the infra-red weatherpicture was completely hidden in those beeps (and yes it took ages for a single picture to appear on the screen) but the tapes did work, and were a good way to leave the computer off if he wasn't planning on viewing the picture as the sattelite moved over our heads...
In an inverse way, one day I used VHS to record Audio and it worked, seem to me that Tape is Tape and records anything that can be recorded. Nothing more
@noisedownloader If that VHS had HI-FI stereo, that would have been a very good recording, some early HI-FI VHS recorders actually had an audio-only mode for doing that.
Very cool that you worked this out. Amateur Radio ops still do this for fun. Several years ago, I captured pictures being sent over a local 2-meter repeater. I used my computer mike into the sound card. My HT (handy talkie) transceiver was the sound source. It was fast and perfect quality using free software on the computer.
I will post a video of the data sounds that I have from the microcassette too. maybe someone out there can tell me how to decode it. It's just some data from an answering machine tape but I just want to find out what it is.
@coondogtheman1234 I don't have the wav of this anymore, the programs i used were audiopiat, which turns the pictures into sounds, and to turn the sound back into pictures is i used sonic visualizer, i cant remember if there free or if i used a trail version. You might also want to try a programs called MMSSTV (i know this one is free) As for the data that's on the microcassette, i have no ieda what it could be, so i dont know what could decode it.
that's OK, I di9d decode what was on the end of this video. I used one iof those youtube to mp3 sites and I opened the mp3 file in my goldwave and played the parts that had the data screeching sounds in them and I saw pics i was like WTF that is cool. I wonder what else I can see by doing this. the pic you put in the end of this vid is some cartoon dude maybe Eric cartman of southpark and he's putting a CD in a stereo. I have a vid of this I will upload.
do you still have this wav file? b/c I'd like to run it thru my goldwave, I have a feature like that on mine where you can see an image of the sound. are any of these programs free?
@coondogtheman1234 byt the way, i just read what i typed and i misspelled audiopaint, blame my stupid keyboard. so anyway the programs i used were audiopaint and sonic visualiser.
The Fourie encoded picture is a caracter from one of your movies. Check out a software called Bitmaps & Waves. It has a ton of settings that you can play with. Try to encode an image, add some audio effects to the sound encoded image (like reverb or echo) and see the result on the decoded image :)
Very fascinating. Nice demonstration of analog-digital transformation. I think it looks neat when the pics get degraded and artifacted like that. TOo bad color isn't a sound..... or is it?
Cool video! I knew that it was possible to store images on tape by converting them to sound,but i have never tried it! There ae those old video TV games that have all the information on cassettes. Anyway,5/5!
Some old computers such as the Amstrad CPC, Commodore 64 and ZX Spectrum could use tape, but those tape loaders were quite slow and not reliable, but the whole idea of it is what inspired me to do this.
it would be intresting when you record the pictures on the reel to reel and play them thru a speaker,record the speaker and then put it on your computer,and see what happens...
l once had a cassette for one of those old computers.Can't recall the make now,but it was possibly Sinclair.Very impressive alternative use for your old Akai...
Did you run the tape in mono record mode - as in using the width of the tape? I noticed only the left meter needle was moving.
I well remember loading 16Kb (wow!) games onto my Sinclair ZX81 via cassette. Quite often the process failed and you had to start again, making life rather too short for bothering!
it was in mono mode, because I didn't see any need for it to be in stereo for this. In mono it only records on to one of the 4 tape tracks, depending on what track you select and whether you're using side 1 or side 2, it doesn't have a full track record feature.
I'm sure it's possible to do it with tape instead of over the radio, later on (probably some time this week), I'll give it try myself and see how it goes.
Thats awesome! Can slow scan TV be recorded on tape? I tried it on MP3 and it worked great, not sure how it could cope with wow and flutter perhaps someone can try it?!! Instead of the radio being there the tape was plugged in instead? MMSSTV is a good free program for experimenting with it :)
They were doing fax over radio as early as the late '20s. Late at night when their normal programming had ended for the evening, radio stations would use fax to transmit documents and photos back and forth between cities. There were plans to sell fax printers to people so they could receive these faxes at home, but the development of television quickly made that obsolete.
Very cool video! I was able to decode the pic in cool edit but I didn't get quite enough resolution to see what it was. I can make out the shape of a character and that's about it. :) JC
Thanks. Try it in the program I used (sonic visualizer, it's free), as it works best on something that shows a monochrome spectrogram, I can't get good enough resoloution in cool edit either because it shows a color one.
that picture sounds cool and the sound looks cool too. wow, i think my head's going to explode
