The Sender service indicates the presence of and provides information concerning an Openhome Sender.
An Openhome Sender broadcasts music on a network in a way that is playable by an Openhome Receiver.
Actions
Counters
Counters are used to manage the changing of the Track, Details, and Metatext information.
When a track changes, the Track Count is incremented, the Uri and Metadata are set, the Details Count is set to zero, the Details are defaulted to blank and zero values, the Metatext Count is set to zero, and the Metatext is set to blank.
Subsequent updates to the Details and Metatext are accompanied by increments in their respective Counters.
The Counters action can be used by clients that are unable to partake in UPnP eventing in order to establish changes in the information provided by the Info Service.
