Demuxed 2018 Video & Streaming Architecture

on YouTube ↗02m

" summary

Conference streaming architecture centers on handling 1080i and 1080p feeds through an HDMI into a Decimator then SDI into an ATEM control switcher that drives projectors and routes back through a Nova Decimator into an old Studio Mini and Thunderbolt conversion. Vision mixing runs on an Intel NUC running OBS which both streams to Twitch and feeds the ATEM while using bonded LTE backup plus house Wi‑Fi. Two cameras feed the Studio Mini, redundancy mostly works except a flaky HDMI cable broke the chain; plan is two laptops and two HDMI cables.
