Re: Composite video from HDMI port
I finally got round to locating the thing and popping the lid off last night. It appears to contain 4 major components for video.
- An anonymous micrcontroller
- An EPROM containing the HDMI decryption keys
- A EP9351 which decodes HDMI serial into 3x8 bit parallel data
- A MDIN 165 digital to analogue video encoder chip.
If I get round to it I may try soldering a load of tiny wires to the pins of the EP9351 and hijack the data as it goes by and feed it to an FPGA.
THE MDIN 165 seems to be the chip that does all the heavy lifting in terms of encoding but I can't find a full datasheet for it - it would be great if that could be persuaded to do the 405 linedness!
