Maybe this will help. Even for TV programming stored somewhere within the
Internet cloud, at some point of time, that TV program had to be transferred
from a source device to the multiple servers, for later consumption by users.
Someone, or some automatic source device, had to schedule that transfer, and
had to send it via a specific IP address (unicast or multicast).
What you think is a big channel and schedule factor exists whether the
recording is done in your PVRs at home, or whether it's done at multiple
servers in the Internet or MVPD "cloud."
