I wouldn't recommend using a Raspberry Pi 2 as a Tvheadend server for the following reasons:-
* The RPi 2 only has one usb bus shared between 4 usb ports and Ethernet & can easily be overwhelmed, it struggles to receive and stream 45mbps (the avg 28E sat mux) over Ethernet. So say you want to stream an HD service at about 15mbps it'll only take three clients to cause issues, welcome to glitch and bitch (by your SO) city.
* You're going to need a fast mSD card if you want decent timeshift & recording functionality, you could save the files over Ethernet but again you're going to run into issues with bandwidth if you have people watching TV at the same time.
Note: Not all applications support timeshift, the only known (sort of) working client is Kodi and the pvr.hts add-on however it's buggy & doesn't shift to where you actually want it to :p.
>I've seen reference to a plugin for Plex Media Server that will offer the TV Streams from TVHeadEnd as a channel. This is where my uncertainty comes into play:
> Will the live TV streams be transcoded by the RPi in the attic running TVHeadEnd, the Plex Media Server, or the RPi at each television running RasPlex? I'd prefer to offload the transcoding to the Plex Media Server, as it has more significant hardware than the RPi's. Or do the RPi2's at the televisions have more than enough hardware to do the transcoding themselves?
The only way you'll get the Raspberry Pi to transcode is by piping it to an external script that runs gstreamer or something else that supports omx.
The RPi really shouldn't need transcoding as it supports mpeg2 and h264 with a license key.
> Say I only had one tuner connected to TVHeadEnd, and three RPi's with RasPlex to stream the live television to through Plex Media Server. If RPi A is streaming one channel, are the other two RPi's limited to viewing that channel as well, or can they view any other channel at the same time so long as it is on the same MUX?
As long as the requested channel is on the same mux then Tvheadend should be able to use the already active tuner leaving the others free.
> * I've seen mention of IPTV. Say a year down the road I switch to Bell Fibe Television IPTV, would I be able to connect an RPi with TVHeadEnd to the IPTV Router to deliver the stream to my other RPi's connected to the television, effectively eliminating the need to rent Bell set top boxes?
I don't see why not but this depends on a number of factors, encryption, concurrent connection limits and whether or not the provider does some weird crap to limit the receiving devices.
> Thanks for the help folks. I'm hoping that this will be the solution for my home. I've got Ethernet everywhere, but no coax. So getting this to work is the only renovation free way to deliver live television throughout the house.
All I can suggest is that you try it and see but don't say I didn't warn you if you run into problems :p
