There are some bits in the active-marker that are "free". Normaly you
have "0" and "1". A Master-Timer active is ">65536" and contains the
master-timer-internal ID-Number of the timer.

Currently the counter is linear, so the first bits are "overwritten".
But i could change it in a way that the first 16 are always untouched by
master-timer. (count << 16). As a new version of master-timer is needed
anyway, this is no problem at all.

Now you could add this special behaviour via (e.g.) bit 1 and bit 2.

bit 0 set = normal timer
bit 1 set = channel-switch timer
bit 2 set = eit-scan timer

So e.g. Master-Timer only needs to set the needed bit(s).

[Nachrichten]
Title = <Nachrichten>
Channel = ARD
Timertype = channel-switch

and Master-Timer sets bit 1.
e.g. count is "3"
ID = (3 << 16) = 196608
ID OR bit 1
196608 | 2 = 196610
So the active-flag is "196610". VDR sees that bit 1 is set and
interprets this timer als only for channel-switching

Another possibiliby would be to make the special case "Start-Time" and
"End-Time" are equal the trigger for this behaviour. (But this way you
couldn't differentiate between channel-switch and eit-scan timers. Which
wouldn't be a problem in most cases i think.)


eit-scan timers can't be generated by master-timer "correctly(tm)" (Out
of scope for master-timer. For this type of timers user-definied
repeating timers fit best(tm) in my eyes)

Real Programmers consider "what you see is what you get" to be just as 
bad a concept in Text Editors as it is in women. No, the Real Programmer
wants a "you asked for it, you got it" text editor -- complicated, 
cryptic, powerful, unforgiving, dangerous.
