I have to transmit B&W images (about 30fps) with resolution of 1980x1080 pixels. I would like to use a HDMI link between the generating device and the imaging device (to have standard connexions and signals). Is the HDMI standard specification take into account the B&W? I mean is HDMI able to use a lower frequency transmission rate that take into account this particular signal? A low frequency rate is required in my application since I have to transmit the signal over a length of 10m to 15m. Is HDMI standard foreseen such signals?
