Some "subtitles" may be present for 2 hours but the packets likely
get repeated at intervals shorter than 20 seconds otherwise one could
not start playback of such a stream from the middle. And i find even
20seconds unlikely long for that. That would implicate if one tuned
to a channel and started watching the channel logo would be missing
for 20 seconds in some cases

Those who are best at talking, realize last or never when they are wrong.
