DISCRET 11
DISCRET 11: Video encryption from 1984
The circuit is based on the pirate decoder from Radio Plans magazine, 1984. This decoder permitted to watch TV shows from a quite famous French TV channel without paying, with the help of some specific ICs and some reflexion. It was based on two video delay line, a sync signal extractor and also a delayed/nondelayed line detection circuit.The original encryption working by delaying lines of the picture pseudo-randomly (with fixed delay times), Radio plan circuit was checking if the line was delayed or not, and with the 2 onboard delays, realign the lines of the picture to make it viewable. A Wikipedia page about this encryption is available (in French).
Discret11 keeps the delays, and also a quite similar sync extraction circuit as the one from the above schematic,however, the goal is to encrypt instead of decrypt, so the line detecting circuitry isn’t used. It’s replaced by frequency dividers, which divide the line frequency in subdivision, so the delayed picture appear every 2, 4, 8 lines, selectable using two rotary switches. The occurency of delayed lines can be set to random (with a circuit based on Random Gate from Yves Usson/Yusynth), in an attempt to reproduce the original encryption (a pseudo-random sequence of a length of 6 frames). The delay times, fixed on the base circuit, can be modified using potentiometers, which will delay the whole line but will also affect color the line (as the phase of the chrominance signal is delayed with the rest of the signal). A wipe between original, non delayed, signal and the delayed signal has been added. Two potentiometers adds glitch effects, with a switch to turn them off.
The project is now available assembled through the webshop.

Luma keying is a good way to constrain effects to certain parts of the source image.
Here, Détail pre-filter output is connected to Seuils which generates hard keys out of it, with each channel of Seuils controlling each of the parameters of Détail.
Recorded in Composite NTSC 480i59.94.
Let me know in the comments if there is any module combinations you’re curious about!

Long time no sync!
Past month has been quite busy, been working on setting up a fixed video recording setup (finally), and here is the first recording made with it! (Need to work on the lighting still).
The now classic Détail and CBV001 combo, with CBV001 used to process the modulation going to Détail. Getting the best of CBV001 distorsion without worrying about loss of sync as Détail preserves it.
Recorded in Composite PAL 576i50.
Stock of Détail and CBV001 are low, so might be the right time to grab one!

On my way to @superbooth_berlin can’t wait to talk about analog video non-stop for 3 days!
First picture is from last year booth, coming with a different setup this year, come check it out and play the video synth at booth W201!

For the next couple weeks, I’ll be trading LED and LCD ligthing for true analog lighting (the sun). So check Syntonie website for the shipping schedule, which will get back to normal after Superbooth on May 14th.

Update on standalone options for CBV001, Stable and Détail: the enclosures are now available separately on Syntonie webshop.
This is mostly to make it easier in terms of keeping things in stock, and so there’s no wait for a specific batch of standalone units to be put together (as long as modules and enclosures are in stock of course).
It can also be a way to offload your modular case by making the module standalone.
Pictures are Détail in its standalone incarnation.
(merci @leon.neon.glow pour les superbes photos!)

First round of Détail has shipped, thanks a lot for the support!
Note that Détail can be made standalone, the enclosure and power supply are now available as a separate listing on Syntonie webshop.
I’ll make a dedicated post about standalone options soon.
Captures above are Détail going into Stable, recorded in Composite PAL 576i50 with Analog to SDI + Video Assist.
Stable adds another layer to the effects Détail achieves like solarization, hue modulation, etc...

Building a proof-of-concept RPi frame sampler w. cyberboy666 ! Records ~30 seconds NTSE 24bit video when GPU split is set to 128MB - with some additional #discret11 for effect. Code up on http://github.com/autr/rpi-frame-sampler #raspberrypi #openframeworks #videocircuits #videosynth

Détail is now available through Syntonie website! Some units will be on their way to retailers soon as well.
Inspired by old school video detailers, it is based around a lowpass/highpass filter, which can either soften/blur or enhance/sharpen the incoming video signal. It outputs a fully compliant Composite/Component Y video signal, meaning that the effects it produces can be pushed to the extreme without requiring stabilisation (unlike most analog glitch video devices).
Demo video is up on Youtube (link in bio), and a more in-depth description is available on the webshop listing.
Specs:
- 12HP
- 200mA +12V
- 0mA -12V
- 0mA +5V
- 42mm deep
Can be powered through standard Eurorack 16pin connector or DC barrel connector.

Discret11 CV test. Slightly better quality available on my YT channel. Process:
Discret11 glitch effect is modulated by a sample and hold, this same sample and hold is also sent to a pitch quantizer to play the synth.
