>its actually the other way around, HDMI is secretly just DVI HDMI signalling is actually extension of DVI, it embeds TERC4 data islands containing extra metadata and PCM audio during blanking interval. (yes, I was surprised at beginning but HDMI/DVI also have blanking periods just as VGA) https://warmcat.com/hardware%20design/hdmi/fpga/2015/10/21/h... |

It doesn't have any error detection or correction. The timing of the signal is still based on CRT TV's.
Really the whole lot should be done away with and replaced with something properly bidirectional, and preferably IP based so it can be routed anywhere.
