 VDR Plugin 'streamdev' Revision History
 ---------------------------------------
  
+- Implemented multi-device support for streamdev client (suggested by johns)
 - Basic support for HTTP streaming of recordings
 - Close writer when streamer is finished
 - Don't abort VTP connection if filter stream is broken

 The parameters "Remote IP" and "Remote Port" in the client's setup specify the

-client, you will have to restart VDR. However requests to switch channels will
-be refused by streamdev-client once it has been deactivated. All other settings
-can be changed without restarting VDR.

-The client will try to connect to the server (in case it isn't yet) whenever 
-a remote channel is requested. Just activate the client and switch to a 
-channel that's not available by local devices. If anything goes wrong with the 
-connection between the two, you will see it in the logfile instantly. If you 
-now switch the client to a channel which isn't covered by it's own local
-devices, it will ask the server for it. If the server can (currently) receive
-that channel, the client will show it until you switch again, or until the 
-server needs that card (if no other is free) for a recording on a different 
-transponder.

+you configure here. Each of these devices opens one connection to the server
+and becomes associated with one of the server's devices (typically a DVB card)
+on demand.
 
 Only the needed PIDs are transferred, and additional PIDs can be turned on
 during an active transfer. This makes it possible to switch languages, receive
-additional channels (for recording on the client) and use plugins that use

+So for viewing live TV a single device is sufficient. But if the client needs
+to receive channels from different transponders simultaneously (e.g. for PiP or
+client side recordings) a second device becomes necessary.
+
+To allocate additional devices, just increase the number and push the OK button.
+There's no need to restart VDR. Deleting VDR devices on-the-fly is not possible.
+However requests to switch channels will be refused by redundant devices.
 
 The default timeout of 2 seconds for network operations should be sufficient in
 most cases. Increase "Timeout" if you get frequent timeout errors in the log.
