Well, I guess this explains some of my "why the fuck is this even an option" when trying to make a TV just display the signal as it was received.
- p_l 4y agoYeah, the simplest possible circuitry for driving a flat panel TV from HDMI (except the HDCP block, which AFAIK can be placed inline before the display logic) would be to declare the 720i/p capability and then just... pump the data straight onto display interface with some buffers here and there meaning to drop the porches, driven all by HSync/VSync signal recovered from the HDMI clock. :V
