One stream, one channel at a time.

You can change channels through a Playlist.

Multicast will let everyone see the same channel at a time.

Multiple channels simultaneously requires multiple streams.

Yes, you need a dedicated receiver for each stream.

Yes, either you can change channels for specific stream through a list-of-channels Playlist or you can switch between streams through a list-of-streams Playlist.

It's physically impossible for a TV Tuner, Satellite Tuner or Cable TV tuner to select more than a single channel at a time. So if you want to view, stream or select more than one channel, you need more than one tuner. Even Picture-in-Picture requires 2 tuners to select 2 channels.

Good luck on your quest!

OK, I stand corrected, or with a little change, one tuner = one frequency, however that single frequency can include an mpeg transport stream with multiple muxed channels inside of it.

So, any digitally muxed single frequency can contain several channels up to the capacity of the carrier. Just didn't want to supply too much info.

Thanks "Guest" for your example.

you have to retrieve the PAT and then select the right PID for the channel you want to watch, I don't know how you can do this in vlc, but it's the principle.
