Hi.
Now it is becoming popular to support the archive of channels from the iptv server. Several plugins already allow you to do this. Planning to add this feature to tvheadend?
I read the examples and see that the implementation is not very complicated. When accessing from epg, they simply add the line "?utc={utc}&lutc={lutc}" to the channel url. {utc} is the start time and {lutc} is the end time of the TV show in epoch format.
