Abstract: A system and method for dynamic reconfiguration of network topology for low-latency media transmissions. Under conditions where latency is not a large issue, the system establishes a standard infrastructure type wireless configuration. Under latency sensitive conditions such as the transmission of media that must be rendered synchronously, a topology of direct connection between the source device and rendering devices is chosen. When packet receipt issues between the source and one or more rendering devices occurs, the data pathway between network member devices is modified to re-establish reliable connection.

Abstract: A system for transmission and rendering of media data over an Internet Protocol network from portable data storage source devices to spatially-separated destination devices located at lifestyle-determined locations. Destination devices are brought online by a discovery process as they come in the vicinity of a source device. In the interest of speed, discovery messages utilize low-overhead, asynchronous messaging. The discovery process begins with multicasting from a source device to local destination devices of discovery messages which include a unique session key and zone, priority and ID specifications, followed by unicasting of a discovery acknowledgement message from destination devices to the source device, and unicasting of a configuration message from the source device to destination devices. In one preferred embodiment, the latest source device to come into the vicinity of a destination device becomes the source of the media rendered by the destination device.

Abstract: A system for event-based synchronized multimedia playback, comprising a media source device and a plurality of destination devices, each destination device comprising a local clock, and a synchronization module on one of the devices. The synchronization module transmits common events, En, each with a unique event number, to each of the plurality of destination devices. Each destination device records time Dxn when event En is received and transmits an acknowledgement message back to the synchronization module comprising time Dxn and event number n. The synchronization module determines phase and frequency differences between clocks of respective destination devices; computes a frequency adjustment to compensate for phase and rate differences; and directs each respective destination device to adjust its clock phase and frequency accordingly. Each destination device adjusts its local clock as directed or may perform a sample rate conversion on sample data in order to enable synchronized media playback.
