AN OVERBROAD PATENT ON Wireless Audio - This application from Logitech seeks to patent the idea of...Forwarding a media stream from a first media output device to a second media output device! 10 minutes of your time can help narrow US patent applications before they become patents. Follow @askpatents on twitter to help.

QUESTION - Have you seen anything that was published before 8/25/2011 that discusses:

  • Sharing a media stream between two media devices

If so, please submit evidence of prior art as an answer to this question.. We welcome multiple answers from the same individual.

EXTRA CREDIT - A reference to anything that meets all of the criteria to the question above AND ALSO terminates the first media stream when it is transferred to a second media device

TITLE: EASY SHARING OF WIRELESS AUDIO SIGNALS

Summary: [Translated from Legalese into English] A user commands (with voice, button, gesture, anything) a first media output device (e.g. an iPhone) to stream to a second media output device (e.g. a TV)

  • Publication Number: US20130117693 A1
  • Application Number: US 13/567,203
  • Assignee: Logitech
  • Prior Art Date: Seeking prior Art predating 8/25/2011
  • Open for Challenge at USPTO: Open through 11/5/2013

Claim 1 requires each and every step below:

A method comprising:

  1. receiving, at a first media output device, streaming media from a media source device;

  2. receiving, at the first media output device, a command by motion or voice to share the streaming media with a second media output device; and

  3. initiating, by the first media output device, sharing of the streaming media between the first media output device and the second media output device.

In English this means:

A method, comprising:

  1. Streaming media to a media output device

  2. Receiving a command to transfer the streaming media to a second media output device

  3. Streaming the media from the first media output device to the second media output device

Good prior art would be evidence of a system that did each and every one of these steps prior to 8/25/2011

You're probably aware of ten pieces of art that meet this criteria already... separately, the applicant is claiming A reference to anything that meets all of the criteria to the question above AND ALSO where the first media output stream is terminated when it is streaming to a second media device


"easy sharing of media from one media output device from a first user to a media output device of a second userfrom the Applicant"

Apple's AirPlay technology/branding (September 1, 2010) seems to fit the bill. One can stream audio/visual streams, for example YouTube/NetFlix/etc to iPhone/iPad to AppleTV. Unfortunately I have been unable to find a document detailing everything, but I have identified some Apple patents that may apply:

This looks like it was preceded by http://www.google.com/patents/WO2006133764A8 "A method for establishing a paired connection between media devices"

" ABSTRACT A method for establishing a paired connection between first and second media devices >across a network includes transmitting a first information message across the network including an identifier that includes a request to pair the first and second media devices. When a second information message is received from the second media device within a first predetermined time period, the first device retrieves an identifier of the second device and transmits a confirmation message across the network including the device identifiers. A paired connection between the media devices is completed after a corresponding confirmation message from the second device is received within a second predetermined time period."

Does this count: https://sonos.custhelp.com/app/answers/detail/a_id/126/kw/mesh

It mentions a mesh network between separate Sonos devices. The date published mentions 05/13/2004, but the document has been updated in 01/07/2013.

The picture of the mesh network: https://www.sonos.com/graphics/rn/FAQ126/SonosNet-wireless.PNG is dated as modified on 17 July 2008 16:43:45.

VLC media player has had this functionality for many, many years (very handy to do multi-room audio at parties for no cost!). See (dated 2005): http://www.videolan.org/doc/streaming-howto/en/

The page linked above demonstrates all of the three required criteria for prior art but does takes some reading to fathom. The first page I found that walks you through it I've linked to below, dated 2009: https://github.com/videolan/vlc/commits/66d45378d23e7420a5facdcebf83aab95459a3fc/modules/gui/macosx/wizard.h

VLC is open source and stored on GIT, as such it's trivial to confirm at the code level when a feature was added, to help a little the code for the wizard (in Mac) has a header file with a date starting in 2005: https://github.com/videolan/vlc/commits/66d45378d23e7420a5facdcebf83aab95459a3fc/modules/gui/macosx/wizard.h

Windows Media Player version 12, released in 2009, has the Play To functionality, which does precisely this. See this Wikipedia Article. http://en.wikipedia.org/wiki/Windows_Media_Player.
