Abstract: Systems and methods for negotiating control of a shared audio or visual resource are disclosed. A request for control of a shared audio or visual resource is received at an arbiter. The arbiter maintains existing state information for ownership of the shared audio or visual resource and ownership transition conditions of the shared audio or visual resource. The request is received from one of a process executing on an embedded system and a process executing on a mobile computing device. New state information regarding ownership of the shared audio or visual resource is determined based at least in part on the request for control and the ownership transition conditions. The new state information indicates which of the processes controls output of the shared audio or visual resource.

Abstract: Methods and systems provide synchronized sharing of multimedia between multiple devices. The multiple devices may form an ad-hoc network for sharing of multimedia. In an embodiment, group members may have playlist manipulation privileges such as pausing, rewinding, fast forwarding, or adding tracks to the playlist (116). A system may stream or distribute content according to the shared playlist (116). Playback may be synchronized for group members so that everyone is exposed to a same part of the content at the same time.

Abstract: Techniques are described for synchronizing multiple time-based data streams with independent clocks wherein relationships between clock rates of timing devices associated with the time-based data streams are determined, and based on these relationships, times in at least one of the time-based data streams may be translated to times in any of the other time-based data streams despite the data streams having independent clocks.

Abstract: One embodiment provides for a media playback device comprising a memory device to store instructions, one or more processors to execute the instructions stored on the memory device, the instructions to cause the one or more processors to provide a playback queue manager to manage one or more media playback queues including a set of media items associated with a scheduled event; and a playback routing manager to determine an output destination for the media items based on context associated with the scheduled event.

Abstract: Methods and systems provide for coordinated control between multiple devices of playback of a media track or playlist. The multiple devices may form an ad-hoc network for sharing control of media. A control device may coordinate control of the playlist and facilitate playback of the media at a playback device. Then when the control device leaves the group, a second device in the group will seamlessly become the control device and control playback and playlist coordination. The playback device may also be the control device. The playback advice may be a network-enabled speaker. Where the playback device is separate from the control device, the playback device may maintain sufficient information to operate without a control device until a new control device is selected.
