There was some effort to reverse engineer those devices [1] so that one could use for example either transmitters or receivers paired with normal PCs and not just connecting them straight each other. There are also newer models around, though I'm not aware of any reverse engineering efforts so far. If you want to tinker with them, please leave some writeup of the results. Beware that there are both HDMI over IP and aesthetically very similar, but often cheaper, HDMI over Ethernet cable adapters. The 2nd ones contain no brain and can't do any IP encapsulation, they're essentially just level translators using CATx cable to carry the HDMI signals, and of course aren't compatible with any network devices, switches, etc. For that use, you want HDMI to IP transmitters and receivers, which should be clearly marked as capable of working in a network environment. Check carefully the features before buying, because some among the stupid level translators sold on the usual channels are marked as HDMI over IP, which they clearly are not. 1 - https://blog.danman.eu/reverse-engineering-lenkeng-hdmi-over-ip-extender/ https://blog.danman.eu/reverse-engineering-lenkeng-hdmi-over...
