What is the difference between Network Standby Mode and Eco Mode?

Standby Mode:
This selects what type of standby mode your player will use.
In Network Standby mode your player will still be controllable by the StreamMagic app and other network services.
Standby Mode is a low power mode
(0.5 Watts). The unit should be left in Standby Mode when not in use.

In Eco mode your player will use less power than in Network Standby mode, but will need to be switched on either by the front panel or the remote control before it can be seen and controlled by the StreamMagic app and other services.
