摘要： Systems, methods, apparatus, and articles of manufacture to provide root re-selection in a spanning tree protocol are disclosed. An example method includes transmitting, from a current root device on a playback network, a query message to a router on the playback network. The example method includes evaluating a response received from at least one intermediate device between the current root and the router, the at least one intermediate device relaying the query message from the root to the router and transmitting a response back to the current root device indicating a root path cost associated with that intermediate device. The example method includes determining, based on the received root path cost(s), an updated designation of a new root device for the playback network. The example method includes, if the new root device is different from the current root device, exchanging bridge priority between the current root and the new root.

摘要： Techniques for managing a playlist in a multimedia system are disclosed. According to one aspect of the techniques, the playlist is structured to be able to include as many items as desired. To facilitate the manageability of such playlist, the playlist is built with a plurality of items. Each of the items is associated with metadata that includes information related to, for example, artist, album, genre, composer, and track number. The metadata for each item may be parsed, updated or logically operated upon to facilitate the management of the playlist. In another embodiment, each of the items is either a single item or a group item. A single item contains metadata of a corresponding source. A group item contains metadata of accessing other constituent items, which again may be single items or group items. As a result, the playlist can accommodate as many items as desired in a limited memory space without compromising the manageability of the playlist. Each of the items can be removed from, added to, or moved around in the playlist without concerning that an item may further include many items therein.

摘要： Techniques for automatically configuring necessary parameters of a device to be coupled to a network with minimum human intervention are disclosed. In one embodiment, a wired and/or wireless Ad-hoc network is established to facilitate communications among a group of devices. When a new device is added to the network, a rudimentary communication path is initially established between one of the devices in the network and the new device such that necessary parameters (e.g., SSID, WEP security, channel frequency) can be exchanged for the new device to function properly in the network. To ensure the parameters are exchanged in a secure fashion, an additional public security procedure can be used between the two devices.

摘要： A system is described for maintaining synchrony of operations among a plurality of devices having independent clocking arrangements. A task distribution device is to distribute tasks to a synchrony group comprising a plurality of devices to perform tasks distributed by the task distribution device in synchrony. The task distribution device distributes each task to synchrony group members over a network. Each task is associated with a time stamp that indicates a time, relative to a clock maintained by the task distribution device, at which synchrony group members are to execute the task. Each synchrony group member periodically obtains from the task distribution device an indication of current time indicated by its clock, determines a time differential between the task distribution device's clock and its respective clock and determines therefrom a time at which, according to its respective clock, the time stamp indicates that it is to execute the task.
