I just committed code to CVS to handle _most_ of this functionality.
Basically, support's there for switching inputs manually (using the 'c' key)
and for switching to an input and changing channels on an external device
(using an external program) automatically. So, telling the TV code to switch
to channel 'Composite1:25' would switch to the Composite1 input of the TV
card, and call an external program like 'changedevice 25' to change the
channel on the external device.
So, if you'd want to finish off the feature, and have it be useable with
everything, like scheduled recordings and live tv, here's what needs done:
1) Modifying the database structure to use a string instead of an int for
channels. This would be pretty easy, just a matter of modifying the database
structures, and then going through the codebase to modify the few places
where it writes an int to the channel number fields.
2) Modifying the grabber scripts to be able to grab multiple sources, and
prepend the proper prefix to the channel numbers it grabs -- maybe:
would grab all the dish channels, create channels in the database like
Composite1:3, Composite1:4, etc., while:
would grab all the regular TV channels and inset them like normal. Basically
just a tiny bit of scripting.
3) Testing it to make sure it all works.
It should be quite easy.. I just don't have any real use for the feature, and
I can't really test it, so I'll probably just leave it as is, until you (or
someone else) submits a patch to finish things off.
