Subject: Info about Proyect of Digitalman (3Chip)

I tell you that I made the project of Digitalman (that changed to the mail and not it) with a friend and this it was the result:
- we put preset to him in the zone of clamp to improve the brightness
- We made an amplifier to operational with variable gain to the entrance of the circuit because the signal level varied
- We managed to put it inside of the television sets (by necessity, all we do not have VCR)
- To the all this Project work well, the only disadvantage is: Channels that return to positive the video, the soft does not detect it and therefore we see in negative. We are thinking about a separator of horizontal to transistor when coming out of the circuit, soon to create a window in the correct line of video with an counter and to command, with a AND between the Pic and the key, the invertion. Or to use the integrated LM1881 , but would raise the cost of everything.
With this I want to arrive at the following thing: I have doubts of the line of video where the information comes(PAL-N Argentina, cablevision and multicanal) from invertion and finally the code still has randon invertion but i have not become familiar with Assembler. Somebody can give a hand us?
thank you very much.
Dasman :-)
