+
+The tuner (or network if using IPTV) with the highest priority value 
+will be used out of preference. If the tuner is busy the next available 
+with the highest priority value will be used. 
+
+An example:
+
+Tuner            | Tuner A | Tuner B | Tuner C 
+-----------------|---------|---------|--------
+Priority         | 100     | 50      | 80
+Status           | BUSY    | IDLE    | IDLE
+
+In the above table *Tuner A* is busy so Tvheadend will have to use the 
+next available idle tuner which in this example is *Tuner B* and *Tuner C* 
+but because *Tuner C* has the higher priority of the two Tvheadend will 
+use that instead of *Tuner B*. If no priority value is set for any tuners 
+Tvheadend will use the first available idle tuner.

+Streaming priority is like the *Priority* setting (above) but only 
+applies when streaming over HTTP or HTSP. If no streaming priority value 
+is set (0) the priority value is used instead.
