I have no knowledge of the spec for HDMI so was hoping someone here might.
As far as I can tell all video and audio data is transmitted using the four differential TDMS 0/1/2/CLK signal pairs. So is it possible to distribute using only these signals or will the receiving device refuse to accept it if, say, the DDC channel is missing. Basically, am I snookered by DRM?
HDMI cables don't come cheap, and the point of this exercise is to do it the cheapest possible way, so I thought I'd find out if this is a dead duck before I start chopping.
PS. Yes, I know I can buy devices to do this but where is the fun in that Plus they are about 5 times the price here they are in the US or UK.
PPS. The runs are quite short but probably not short enough, so I do realise that a TX driver and RX buffer may be required. I'll cross that bridge when I come to it (maybe come up with something to utilise the batch of RS485 line drivers currently gathering dust and cobwebs in the shed.)
