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.

Going offline for the next week, trading video synthesis for photosynthesis in the French Alps ☀️
Orders will start shipping again on July 21st, and I’ll catch up with emails and dm at the same time.
STVC bundles are running low, so if you were interested in getting one, don’t wait.
Keep patching and see you soon!

First round of STVC bundles have been shipped! A couple more are available still!
Here is a patch made with it, source video goes to Stable, then CBV001 and finally Détail, with luma-based modulation on Stable and Détail parameters.

Introducing Système de Traitement de Vidéo Composite (STVC), a bundle that includes CBV001, Détail and Stable, making a really versatile Composite video processing system.
The bundle is offered at ~15% off, in other words, it’s a free CBV001 or some spare cash to get a case!
Limited to 10 bundles. Available now on Syntonie webshop.
Case is not included, a @4ms_company POD 40X is used on the pictures.
(Merci @leon.neon.glow pour les belles photos!)

Video synthesis speed patching #1
- Shapes/ramps from Rampes are sent to a 1st Cadrans set as crossfaders (white cables)
- Slow modulation from VHS Baja is going to 1st Cadrans CV inputs (purple cables)
- Outputs of 1st Cadrans going to Solaire for mixing/solarizing (green cables)
- Outputs of Solaire going to a 2nd Cadrans for final color balance/inversion/negative space (black cables)
- Outputs of 2nd Cadrans going to Sortie for RGB encoding to 720p60 Component (orange cables)
Video sped up 3 times, and capture is tilted 90°

I’ve been asked about how Stable and Solaire looks when patched together, so here we are!
Solaire is based around full wave rectifiers, which when applied to video, produces an effect known as solarization. It makes the picture brightness « fold on itself », and it is here used as modulation on Stable parameters.
In the second part of the video, the post-processor output of Stable is used instead of the pre-processor output, creating a feedback loop and Solaire having quite a high gain (up to 16 times), it produces a lot of noise (let’s see how it get through Instagram compression).

Now using Isohélie as a processor for Détail self-modulation, yielding those « paint-by-number » kind of effects.
Recorded in Composite NTSC 480i59.94
Isohélie is currently out of stock on Syntonie website, a new batch is on the way. However, if you’re looking for one right now, there is probably some available at retailers.

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.

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.

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!
