Abstract

A system for synchronized broadcast of media content across large networks, comprising a media source stored and operating on a network-connected electronic device that broadcast media content, a first media receiver stored and operating on a network-connected electronic device that receives the media content and re-broadcasts it, and a plurality of further media receivers stored and operating on network-connected electronic devices that receive the media content from the first media receiver, and a method for synchronized broadcast of media content across large networks.

Claims (15)

1. A system for synchronous playback of media using a hybrid BLUETOOTH™ and Wi-Fi network, comprising:

a media source stored in a memory of and operating on a processor of a first network-connected electronic device, and configured to communicate via BLUETOOTH™;

a plurality of media receivers each respectively stored in a memory of and operating on a processor of an additional network-connected electronic device, each configured to operate a media synchronization component and configured to communicate via a Wi-Fi network;

wherein the media source transmits media content to a first media receiver via BLUETOOTH™;

wherein the first media receiver receives the media content from the media source via BLUETOOTH™ and transmits at least a portion of the received the media content to a plurality of second media receivers via the Wi-Fi network; and

wherein each media receiver is configured to render the media content it receives synchronously with the media source using a media synchronization component.

2. The system of claim 1 , further comprising a media synchronization service, wherein the media synchronization service provides synchronization information to the media synchronization components of at least a portion of the plurality of media receivers for media playback.

3. The system of claim 2 , wherein the media source operates the media synchronization service and broadcasts the synchronization information to the media receivers.

4. The system of claim 3 , wherein at least one of the media receivers uses the synchronization information during media playback.

5. A method for synchronous playback of media using a Wi-Fi network with the media originating from a BLUETOOTH™ source, comprising the steps of:

selecting, at a media source stored in a memory of and operating on a processor of a first network-connected electronic device, media content for playback;

transmitting the selected media content for playback to a first media receiver stored in a memory of and operating on a processor of a network-connected electronic device via BLUETOOTH™;

receiving, via BLUETOOTH™, at the first media receiver, the selected media content from the media source;

transmitting, from the first media receiver, the selected media content to a plurality of additional media receivers via a Wi-Fi network; and

synchronously rendering, on each media receiver, the selected media content.
