I remember seeing patches for marking channels as identical in terms of EPG (so e.g., a DVB-S version of the channel can automatically share the EPG entries from the DVB-T version), but has anyone worked on a patch for identifying simulcasting channels, or even had some preliminary design thoughts for how one could be implemented?
I can imagine at least the following two use cases:
1) When watching live TV, channel '1' automatically selects the 'best' available version of 'BBC One London' depending on available tuners - e.g., rotating through BBC One HD (DVB-S2), BBC One (DVB-T2), BBC One (DVB-S) and BBC One London (DVB-T). This is much more intuitive than having to manually find an available broadcast of the channel.
2) For recordings, if a timer needs to start a recording on 'BBC One London', depending on its priority and a 'required quality' attribute it will similarly locate a tuner to make the recording with. Assuming it needs the DVB-S2 tuner for HD, if someone with lower priority is currently watching live TV on BBC One HD via DVB-S2 (and only one HD tuner is available) then they will be transparently switched down to the next available tuner quality.

Hi. This is an interesting topic and I have had exactly the same ideas. But I think this violates Klaus's "Keep it simple" philosophy and (as usual) I tend to agree with him. /Magnus H

If you've ever read the algorithm that picks the best possible device for a recording, you'd probably agreed that we're already way too far from keeping it simple. These rules are already way too complex. Adding the complexity of choosing from different quality sources and up/downgrading other receivers would probably push this a lot further towards insanity.
Cheers,

Even without the primarylimit it's still deadly complex. The very clever programming syntax used for the device selection makes it very difficult to understand and also to debug.
I have an old idea in my head but I've never taken the time to do so, it's also quite erratic: disable channel and device management and allow an external program to decide how to deal with devices and channels. I wouldn't want to start from scratch and work around dvbstreamer, vdr and its plugins are wonderful ! I love it ! (it's just the device and channel management that are too limited imho)
I'm not really into C++, it might already be possible to let plugins take over the channel and device management but i doubt it.
