[linux-dvb] How to handle multiple frontends?

[Klaus Schmidinger]

I'm wondering how an application is supposed to handle
devices with multiple frontends.

Let's assume a device that provides

  dvb/adapter0/frontend0        DVB-S
  dvb/adapter0/frontend1        DVB-T

so that it can receive both DVB-S and DVB-T. Does this
mean that it can simultaneously receive one DVB-S transponder
and one DVB-T transponder? Or can it receive either a DVB-S
*or* a DVB-T transponder, but not both at the same time?
