learned today that people *really* underestimate how complex digital video signal transport is

i examined my assumptions and learned that they include "ah, I think everyone probably has at least a basic understanding of gigabit line codes and SerDes". that... that would explain why

@whitequark Honestly if I were designing a digital video protocol in 2024 I'd leverage as much existing open standard tech and investment as possible while maximizing interoperability and flexibility.

The standard connectors for consumer applications would be RJ45, SFP+, and LC, with QSFP+ and MPO as higher-performance options targeting professional/studio end users. DACs being used for short range and fiber / EOE for long range.

Framing would be IPv6 over 10/25/40/100G Ethernet, using link local addresses by default but with routability possible for more complex topologies.

Replace EDID with a standard discovery protocol, either HTTP to download a metadata file from a well known URL or maybe something mDNS based that would simultaneously provide device discovery.

Video transport would be uncompressed RGB24 (maybe with YUV and high-bit-depth as optional addons) over UDP, probably using RTSP or similar.
