Abstract

A system for synchronized media playback to multiple mobile receiver devices, comprising a network-connected media source device that prepares media content for viewing by separating it into a plurality of media streams, a plurality of network-connected media receiver devices that each receive a plurality of media streams and synchronize their playback relative to one another, and a method for providing synchronized media playback to multiple receiver devices.

Claims (13)

1. A system for broadcasting media from a stationary source to multiple mobile devices over Wi-Fi, comprising:

a media source stored in a memory of and operating on a processor of a first network-connected and physically stationary electronic device;

a plurality of media receivers each respectively stored in a memory of and operating on a processor of a network-connected mobile electronic device, each further comprising a synchronization module that directs the rendering of media content;

wherein the media source broadcasts media content via a network; and

wherein at least a portion of the plurality of media receivers receives at least a portion of the media content from the media source and renders at least a portion of the received content in a synchronized manner with regard to the media source, using the synchronization module.

2. The system of claim 1 , further comprising a media synchronization system stored in a memory of and operating on a processor of a network-connected electronic device, wherein the media synchronization system directs the operation of a synchronization module on a media receiver for synchronized playback of media.

3. The system of claim 2 , wherein the media synchronization system operates on the media source.

4. The system of claim 2 , wherein the media synchronization system operates on at least the first media receiver.

5. A method for broadcasting media from a stationary source to multiple mobile devices over Wi-Fi, comprising the steps of:

broadcasting, from a media source stored in a memory of and operating on a processor of a first network-connected and physically stationary electronic device, media content;

receiving, at a plurality of media receivers each stored in a memory of and operating on a processor of a first network-connected mobile electronic device, at least a portion of the media content; and

directing, using a synchronization module operating on at least one of the plurality of media receivers, the rendering of media content in a synchronized fashion with regard to the media source.

6. The method of claim 5 , further comprising the step of synchronizing, using a media synchronization system, playback of the media content on all devices synchronously.
