A PCB design is under consideration, for when I get back to the UK. Currently sitting around the pool whilst on holiday in majorca. Didn't bring my laptop so can't design circuits
The video decoder device I mentioned is part of my updated scandoubler design, utilising the Averlogic AL250 in YCrCb mode to better suit 18 bit LCD panels, if the screen refresh rates are ok.
The encoder device supports composite, Y/C (S-Video), RGB & YPrPb all via I2C conttrol. A neat solution. Plan to buy some of these from Farnell for video experiments shortly.
The CPLD is to create the equalising pulses for
the TVs benefit. This approach should also work with other retro equipment and modern TVs.
Time for some sangria!
