said by NuShrike:TV (air or cable) is multicast on paid-for, generally one-way, dedicated frequencies, unmulti-tasked frequencies, so you failed.
That's one broadcaster to multiple receivers (with repeating rebroadcast stations) so it takes much, much, much less bandwidth than the point-to-point bidirectional cellular, mobile data on a tower.
Please educate me on the ways of UDP. and UDP Multicast.
