-I want always receive Channel X
-The user should switch if he want to
-And I want to allot some receiver for some channels(vpids)
But this needs some management.
It's difficult to explane, but I try:
//some defines:
Userreceiver(int channel) : the user want to see or
record some channel
myreceiver(int channel, int vpid) : I want to receive some data from
channel
staticreceiver(int channel, int vpid): this receiver should always
receive the vpid from channel
Same Transponder {1,2,3,4}{5,6,7,8}{9,10,11,12}{13,14,15,16}
********
Getting started:
Device 0: Userreceiver(4)
Device 1:
Device 2: staticreceiver(14,42)
------
->Add new myreceiver(5,213): can be attached to Device 1
Device 0: Userreceiver(4)
Device 1: myreceiver(5,11)
Device 2: staticreceiver(14,42)
------
->Add new myreceiver(2,113): can be attached to Device 0
Device 0: Userreceiver(4),myreceiver(2,113)
Device 1: myreceiver(5,11)
Device 2: staticreceiver(14,42)
------
->Add new myreceiver(7,413): can be attached to Device 1
Device 0: Userreceiver(4),myreceiver(2,113)
Device 1: myreceiver(5,11),myreceiver(7,413)
Device 2: staticreceiver(14,42)
------
->Add new myreceiver(16,515): can be attached to Device 2
Device 0: Userreceiver(4),myreceiver(2,113)
Device 1: myreceiver(5,11),myreceiver(7,413)
Device 2: staticreceiver(14,42),myreceiver(16,515)
------
->User want to switch to Channel(11): myreceiver(2,113) must be detached
Device 0: Userreceiver(11)
Device 1: myreceiver(5,11),myreceiver(7,413)
Device 2: staticreceiver(14,42),myreceiver(16,515)
------
If I want to add a new myreceiver, the i must find a device where to
attach it.
How I do that?:
I ask each device if it can handle it.
->Add new myreceiver(16,515){
for all devices
if(cDevice->ProvideChannel(16))
attach myreceiver(16,515)
}
so I can find: device0 , device1, device2 or nodevice
If I use prio-1 the always device0 will be found.
If I use prio>0 then the user can't switch to other channels if a
myreceiver is also attached to device0,device1, device2.
maybe I don't understand the prio management of vdr.
device0->attachReceiver(myreceiver,Prio10)
if(device0->ProvideChannel(channel1,11))
device0->switchToChannel(channel1): that ought detach myreceiver!
wouldn't it be good if the switchToChannel can have a prio? Maybe 50.
I hope you understand what I mean. My English is not very good.
