It's not very difficult. Just buy a video scalar and slice the screen into quarters. I have a pile of these devices at work. The delay is one frame (or one field in interlaced modes). They are really straightforward devices generally built out of an FPGA or CPLD and some RAM/RAMDACs and old analog ones are cheap.
