The first decode. No TBC applied, obviously, but just good enough to see that the hardware is working.


Yep, looks horrible. So why is this big news? It means I can finally access the raw signal, in real-time with hardware. I'm using an ARM-based embedded 32bit cpu. It can be programmed in C to decode the video. The sample rate can go up to 144MS/s, way more than enough for HD video. I can also input s-video. However I'm having some bandwidth problems.

For now I can do a type of hardware assisted software TBC, meaning that I can record/embed the sync information so that a software decoder can use it to resize.

I'd like to try raw decoding the VHS direct from the video heads; first I need a good video amplifier, but it can be easily decoded.

Here's what the hsync looks like: http://desmond.imageshack.us/Himg59/...pg&res=landing

Not too bad. I need a tape with a major flagging issue to test.

Slightly related. Looking at HSYNC with Barco video monitor.

edit: I noticed that "plain" analog HSYNC from VHS is a bit more plain than this SDI-passthru if anyone was wondering what all that fuzz was about.
