Overview

A Songcast receiver plays audio broadcast from a Songcast sender.
The Receiver service provides the means for controlling a Receiver source. If a device's Product service reports a source of type Receiver, then that device is guaranteed to bear the Receiver service.

State Variables

Metadata

The metadata of the sender to listen to. In the DIDL-lite format provided by the Sender service.

Uri

ProtocolInfo

Reports the protocols supported in the normal UPnP forum format – a comma separated list of elements of the form

<protocol>:<network>:<contentFormat>:<additionalInfo>

Supported protocol elements are <ohz>, <ohm> and <ohu>. Other elements are normally wildcards *
