The video is gathered is more efficient now because the issues are now seen in realtime, and video is no longer being encoded across the network but locally. Instead, full ATSC streams are sent to centralized points where they are encoded, muxed and the video is processed before uplinked. In the future, the regional uplinks won't have any encoding gear at all. Everything is now about metrics and all that data is gathered. The blips you see are not issues with the uplink but are mostly IRD issues, especially with the HS17. (No secret)
The entire monitoring system was overhauled in the past few years and is now exclusively IP monitoring over the network, and the capabilities are now much better even though it had growing pains. This allows us to see PAT, PMT, PCR, Transport errors in real time. Including any network errors. We can see all of those errors at every point in the entire uplink chain from the incoming, to our encoder, to our mux's, ect and can track down if it's an incoming issue or something else in real time. The tools we have are much better than what we had 5 years ago, by far. AI is a great thing when used correctly.
If you want to learn more about probes and what they can do today, you should check out this link.It's only one tool of many that we now have and it is much more than IP and router-related problems. Everything can be detected in real time and the metrics of it is being gathered. It's pretty crazy but when you can find trends to help save money, it tends to push what gets implemented.
