Spent sometime over the weekend on this project. I am now trying to get it to convert from NTSC as well as PAL. So far getting good results even though it is not completed yet.
For a 525 line signal I have been using both a Hedghog PSC and one of those mini HDMI2AV boxes that can convert from HDMI to PAL or NTSC.
It would appear that converting from 60Hz to 50Hz results in less judder than going from 50Hz to 60Hz.
When completed I will update the firmware on the website. It will require both the FPGA and microcontroller firmware to be updated.
When I get this finished the only thing it wont have been tested converting from is SECAM.
I know very little about SECAM but as far as I understand the luminance portion of the signal is the same as PAL and this is the only part I am interested in.
The video decoder can decode SECAM so I think it should be able to convert from SECAM as well.
