/diy/ - Do It Yourself

I need some advice guys.
A long time ago, I attached an 8 inch crt from a portable TV to a PC, pretty neat, except I had to use a VGA-to-composite and a RF modulator. Quality isn't great because of the modulation and demodulation process, so I want to get rid of it (at least, almost).

The TV main chip is a AN5151. It does the demodulation stuff, controlls deflection and stuff, and has the video output, great. The idea is, keep the modulator and demodulator (because the IC controlls all the CRT stuff and is synced), but I want to bypass the AV signal with the original one.

The main problem is the delay. I've measured something like 1,6us (pic related: up->original down->output of AN5151). I don't know if that time is really a problem. If it is, I need a way to get rid of that. I've got a few delay lines from old TVs, but I read somewhere those are 64us, but I'm not really sure.

>Inb4: Is the output signal the real problem? Yes, I checkd.
