We need an electronic circuit that converts a standard HDMI signal to composite(PAL and NTSC). The job is primarily to make it as small as possible. We only need a video signal no audio. The circuit should be able to accept external power.
We don't necessarily need the final layout, but it's a nice to have. We will be OK with just the schematic - preferably in Eagle. The primary job is to research a system that will do the job with the fewest possible parts that allows for a small PCB footprint. All parts used has to be well documented and in ready supply.
