Black on air, a frozen frame, audio drifting out of sync with the picture: these are the faults viewers actually notice and remember. They are also the faults a human wall-watcher misses, because they happen on channel 31 while the operator is dealing with channel 6.
- 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
