Abstract

A system for media distribution and rendering over a spatially extended wireless network, comprising a plurality of media rendering devices configured as nodes in a spatially extended wireless network. The media rendering devices dynamically establish a hierarchical arrangement wherein a first media rendering device acts as a root node of the hierarchical arrangement. The first media rendering device receives media content over a network and distributes the media content to the remaining media rendering devices using the hierarchical arrangement. The media content is rendered synchronously by each of the plurality of media rendering devices.

Claims (11)

1. A system for media distribution and rendering over a spatially extended wireless network, comprising:

a plurality of media rendering devices each comprising at least one wireless network adapter configured as nodes in a spatially extended wireless network;

wherein the plurality of media rendering devices dynamically establish a hierarchical arrangement wherein a first media rendering device acts as a root node of the hierarchical arrangement;

wherein the first media rendering device receives media content over a network and distributes the media content to the remaining media rendering devices using the hierarchical arrangement; and

wherein the media content is rendered synchronously by each of the plurality of media rendering devices.

2. A method for media distribution and rendering over a spatially extended wireless network, comprising the steps of:

(a) configuring a plurality of media rendering devices each comprising at least one wireless network adapter as nodes of a spatially extended wireless network;

(b) dynamically establishing a hierarchical arrangement of the plurality of media rendering devices, wherein a first media rendering device acts as a root node of the hierarchical arrangement;

(c) receiving media content via a network at the first media rendering device;

(d) distributing the media content to the remaining media rendering devices using the hierarchical arrangement; and

(e) synchronously rendering the media content by each of the plurality of media rendering devices.
