Multi-source Audio Broadcast via Host-mediated Access Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication protocols limit wireless audio broadcasts to a single preselected source device, making it inconvenient for transmitting audio from multiple sources or locations efficiently, especially during events like Q&A sessions where source device switching is necessary.
Innovation Solution
A technique that allows for the transmission of access information for multiple audio streams to sink devices, enabling seamless switching between audio sources without releasing control of the sink device, using a host device to manage and coordinate the broadcast of audio streams over isochronous wireless networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single host device preselects a single audio source device for wireless broadcast, then the sink device maintains simple control and pairing, but the system cannot efficiently transmit audio from multiple sources or locations
Solution Approach 1:
The host device acts as an intermediary that receives requests from multiple source devices and manages access information transmission to sink devices. This mediator approach allows multiple sources to broadcast to the same sink without direct peer-to-peer complexity, resolving the contradiction between multi-source capability and control management complexity.
Solution Approach 2:
The sink device is designed to receive and play audio from multiple different source devices through a universal interface managed by the host. This multi-functionality allows the sink to serve multiple sources without requiring separate pairing or control mechanisms for each source, enabling adaptability while maintaining manageable complexity.
2Adaptability or versatility
If the host device releases control of the sink device to allow source switching, then multiple sources can broadcast, but the sink device loses control and pairing stability
Solution Approach 1:
The host device performs preliminary actions by receiving requests from source devices and preparing access information before transmission to the sink. This advance preparation allows smooth source switching without requiring the host to release control, maintaining sink stability while enabling multi-source capability.
Solution Approach 2:
The system uses feedback mechanisms where the host monitors requests from source devices and manages access information transmission accordingly. This feedback loop allows the host to maintain control of the sink while coordinating multiple source broadcasts, resolving the contradiction between source switching capability and control stability.
3Productivity
If audio broadcast is limited to a single preselected source device, then the system maintains simple pairing and control, but the Q&A session is delayed or interrupted when the person speaking changes
Solution Approach 1:
The audio broadcast system transitions from a static single-source configuration to a dynamic multi-source capability. The host device can dynamically switch between different source devices based on real-time needs, allowing seamless Q&A sessions without physical passing of devices while maintaining ease of operation through centralized management.

AI summary
One embodiment sets forth a technique for managing an audio broadcast. The technique includes transmitting first access information for a first audio stream to one or more sink devices, wherein the first access information is used by the sink device(s) to play first audio content transmitted from a first source device and the first audio content is transmitted over the first audio stream. The technique also includes receiving a first request from a second source device to transmit second audio content to the sink device(s), wherein the first request comprises second access information for a second audio stream. The technique further includes transmitting the second access information to the sink device(s), wherein the second access information is used by the sink device(s) to play the second audio content transmitted from the second source device and the second audio content is transmitted over the second audio stream.
