說明書
In a preferred embodiment, the playback device request signal will always be generated if the sensor detects a specific property or a specific change in a property of this environment within the area of its environment or if the control unit detects a specific change in the property determined by the sensor, in particular if the sensor detects the presence of an identifier and recognizes the identifier of the identification carrier. The playback device request signal can be sent with a time delay, in particular if the playback device does not have a communication channel to the server at the time the playback device request signal is generated.
In a preferred embodiment, the control unit checks in the request routine whether there is an entry in the playback device allocation table for the identifier recognized by the sensor. If there is no entry or if there is an entry that contains a need for an update, the control unit generates a playback device request signal with an indication of a need for an update.
