Link channels for auto switch

[thunderclap 52]

I have an antenna and sometimes it has signal issues and I've never been able to figure out why. For example, NBC will work fine for weeks and then for an evening or two it the signal strength will be low and the channel is unwatchable. I also use IPTV and have these same channels mapped so I can switch if necessary. It would be cool if Emby allowed me to link different channels and if it sensed a signal problem it would automatically switch to the IPTV channel. This way Emby could automatically cycle through linked channels to find the strongest option.
