摘要： Described herein are systems and methods for providing dual control functionality in a networked digital media device. In overview, a networked digital media device advertises a standard digital media device, which is discoverable and controllable by a standard control device in accordance with a standard media control protocol (also referred to as a Device Control Protocol, or DCP). The networked digital media device also advertises a non-standard digital media playback device, the non-standard device being discoverable and controllable by a non-standard control device in accordance with a non-standard media control protocol. These two devices are manifested in the same device hardware, essentially allowing the device to implement dual-control such that it is able to be controlled both as a standard device and a non-standard device.

摘要： A Zone Control service is disclosed which provides for hierarchically managing a plurality of networked media subsystems. This can provide a layer of abstraction for the collection in the form of a single Renderer zone interface represented by a delegated zone controller. This hierarchy establishes a virtual super-system. Although a Zone Control services can be advertised on all networked media devices, the services will typically be unavailable while a device is subservient to, or equivalently under the control of, a zone controller. A single instance of the Zone Control service can reside in a Services Device, co-existing with a Group Control service.
