Wireless Audio Sharing with Metadata and Intermediary Range Extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems for audio and data sharing among devices are limited in allowing users to share music experiences, as they do not enable full stereo sharing, are restricted by transmission range, and lack the ability to transmit metadata like song information, preventing users from identifying the music being shared and limiting the ability to purchase the same audio content.
Innovation Solution
A digital audio player system that enables wireless stereo communication among devices using built-in transmitters/receivers or intermediary devices, allowing users to transmit and receive audio signals and metadata, including ID3 tag information, and enabling rebroadcasting and playlist sharing, with options for secure, closed-network communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless headphones receive music from media devices via wireless transmission technologies, then users can share music experiences wirelessly, but the transmission range is limited and users cannot be too far from the source
Solution Approach 1:
The patent introduces an intermediary device (wireless transmitter or receiver) that acts as a mediator between the media device and wireless headphones. This intermediary extends the effective transmission range by receiving signals from the media device and retransmitting them to headphones beyond the original transmission distance, effectively solving the range limitation while maintaining wireless operation.
2Ease of operation
If prior art wireless headphones are used, then wireless transmission is enabled, but users cannot share music from the same media device simultaneously
Solution Approach 1:
The patent segments the audio signal transmission by introducing multiple independent wireless transmission channels. Each wireless headphone receives a separate stereo signal stream from the media device, allowing multiple users to simultaneously access different music content or the same content independently, thereby enabling multi-user sharing while maintaining full stereo capability for each user.
3Ease of operation
If general transmission techniques such as Bluetooth are used, then wireless communication is enabled, but the transmission is accessible to anyone having the capability to receive that data
Solution Approach 1:
The patent applies local quality by implementing security measures specifically at the transmission and reception points rather than throughout the entire system. Encryption and authentication protocols are applied locally at the media device and wireless headphone interfaces, ensuring that only authorized devices can establish connections and receive transmissions, thereby securing the data stream without affecting the overall wireless communication functionality.
4Ease of operation
If audio sounds are shared wirelessly, then music transmission is enabled, but information about the audio sounds such as ID3 tags is not shared
Solution Approach 1:
The patent merges the audio signal transmission with metadata transmission by combining both data streams into a single unified wireless communication protocol. The ID3 tags and other audio information are packaged together with the audio data and transmitted simultaneously through the same wireless channel, ensuring that recipients receive both the music and its associated information without requiring separate transmission systems.
Data Source
AI summary
A system and method are disclosed for wireless sharing of audio sounds among a plurality of users. A user of the present invention can communicate his or her audio sounds to other users, who can receive the audio sounds wirelessly and choose to rebroadcast them. Along with the audio sound files users can share information regarding the audio sounds being shared, such as title, artist, collection, genre, year, encoding rate, size, playlist, and other desired information. The user of device can opt to set the device to transmit, re-transmit, broadcast, re-broadcast, receive or not to receive play-list information in addition to the audio sound files and the information regarding the audio sounds themselves.
