Building a Standards Converter

[ppppenguin]

Would be possible to do an analogue modulator (need something better than the traditional 1496 chips) and synthesise the carriers in the FPGA that's doing the video conversion. The PLLs in most modern and fairly modern FPGAs will do 200MHz+ with ease. In what is now a pretty old and near obsolete Xilinx (Spartan 3A) I run one of the PLLs at 192MHz which is nowhere near its maximum speed.
