Abstract: Described herein are systems and methods for synchronization in a networked environment. For example, some embodiments provide methods for synchronizing a client device having a client media time reference with a server device having a server media time reference. In some cases such methods are embodied in computer readable code that is executable on one or more processors. Furthermore, some embodiments provide hardware, such as networked media devices that are configured to perform such methods. In overview, in some embodiments a client obtains timing information from a server and, on the basis of this timing information, applies an adjustment to a client control time reference, thereby to synchronize the client media time reference with the server media time reference. Some embodiments are particularly directed to the situation where there is a desire to synchronize networked media devices across a combination of wired and wireless networks.

Abstract: 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.

Abstract: 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.

Abstract: Described herein are various methods and systems relating to the unification of media devices, and more specifically to the provision of wireless audio systems. In overview, two or more wireless speaker subsystem units substantially autonomously form a single wireless audio system having its own control interface. This control interface is used to apply operational changes across the wireless audio system, such as volume adjustment. That is, an operational change may be applied to the system as a whole, and this change is subsequently implemented by each of the individual wireless speaker subsystem units.

Abstract: A method performed by a wireless media device such as a wireless loudspeaker subsystem for configuring and connecting to a media wireless network. The wireless media device first associates to an existing infrastructure based wireless network at a first phase. At a second phase, the wireless media device establishes a secure communications tunnel with a complementary wireless device that has also previously associated to the existing wireless network. Using the secure tunnel, the wireless media device shares with the complementary wireless device data indicative of a set of parameters for a second wireless media wireless network at a third phase. Once this sharing is complete, the wireless media device connects to the second wireless network at a fourth phase.

Abstract: In a network environment such as a wireless packet network, a source node transmits a data stream, e.g., a stream of media packets to a plurality of sink nodes, including the source node transmitting a first data stream of unicast packets addressed to at least a first one of the sink nodes, while other ones of said sink nodes receive while in promiscuous mode traffic on the network including the data stream. Individual ones of the other sink nodes, upon ascertaining that there are packets of the stream that were not received, transmit a re-transmission request to the source node so that the source node can take corrective action, and so all the sink nodes can receive the data stream, even though sent as unicast addressed to fewer than all the sink nodes.
