Human captioning of live output is expensive, hard to staff across languages, and impossible to scale to every channel you run. External captioning services add a cloud dependency to your signal path and put your content on someone else's infrastructure. Meanwhile the accessibility obligations don't move.
- 1 operator cannot monitor 40+ tracks by ear or eye at once
- Legacy probes confirm packet presence, not what airs inside the stream
- Faults survive on air for minutes until viewers or affiliates complain
