Described herein are systems and methods for providing media playback in a networked environment. In one embodiment, a networked media playback device is configured to provide a web server for delivering data indicative of a browser-renderable control interface for the networked media playback device, or for a related networked media playback system. In overview, the user of a networked device, such as a wireless web enabled device, is able to render the control interface in a web browser, and in this manner control playback of digital media via the networked media playback device or networked media playback system.

Systems and methods for providing a media playback in a networked environment

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.

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.

Systems and methods for providing zone functionality in networked media systems

In a wireless network environment, a method of transmitting data from a source device to a set of sink devices, the method comprising the steps of: (a) initially the source device broadcasting packet data collectively to each of the sink devices; (b) the sink devices collecting packet data and identifying missing packets that have been missed; (c) upon a sink device detecting a missed a packet, the sink device separately requesting the transmission of the missed packet by the source device; and (d) the source device separately sending missed data packets.

Media data transfer in a network environment

Described herein are systems and methods for managing the operation of networked media playback devices. One embodiment includes Graphical User Interface for coordinating playback of media via one or more networked wireless speaker devices. In particular, a user is able to 'drag and drop' audio tracks to icons that are respectively indicative of one or more networked wireless speaker devices, thereby to affect playback of those audio tracks via those speaker devices.

User interface for managing the operation of networked media playback devices

A method of keeping global time in a wireless network, the method includes reading a Time Synchronization Function (TSF) to provide an initial time base. An interconnected clock control circuit is employed to read the TSF time from the circuitry used to read the TSF and to implement a local clock based on time values read from the TSF.

Media data synchronization in a wireless network

A method of keeping global time in a wireless network, the method comprising the steps of: using a first 802.11 chip set to read a Time Synchronization Function (TSF) to provide an initial time base; using an interconnected clock control circuit to read the TSF time directly from the 802.11 chip set and to implement a local clock based on time values read from the TSF function.
