When this is complete it will be a worthy successor to the Aurora WC-01. The latter hasn't been available for a number of years. Although Frank is unlikely to attempt standards such as CBS sequential colour, Baird 240/25p should be possible. This was never feasible on the SCRF converters.
The flexibility of an FPGA makes it very easy to program arbitrary output timings though getting the interpolation and other matters right is less simple.
Is there sufficient FPGA capacity to do 405 NTSC? Needs some multipliers and other logic. I can supply VHDL for a PAL/NTSC coder which could be adapted easily for 405 NTSC. Obviously need to store and interpolate the chrominance as well as the luminance.
