Wireless Audio Output Channel Selection Using RSSI Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless audio output devices can only connect to one content providing device and receive audio from that device, limiting their ability to select and output audio from multiple broadcast channels with varying reception intensities.
Innovation Solution
A wireless audio output device that generates a broadcast channel list, filters inappropriate channels, and allows users to select an output channel based on user input, using a processor to manage a whitelist and blacklist, signal strength, and user preferences to guide audio content output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the wireless audio output device receives multiple audio broadcast signals, then the variety of available channels increases, but the device cannot output audio from multiple channels simultaneously and must select only one
Solution Approach 1:
The system performs preliminary actions by automatically receiving and evaluating multiple broadcast signals in advance, generating a sorted channel list before user selection. This pre-processing reduces the complexity of user operation while maintaining high adaptability.
Solution Approach 2:
The system uses feedback mechanisms by analyzing reception intensity (RSSI) and user selection history to dynamically adjust and sort the channel list, presenting the most suitable channels first to users based on real-time and historical performance data.
2Loss of information
If the device presents all received broadcast channels to the user, then complete channel information is provided, but inappropriate channels with poor reception quality are also included reducing user satisfaction
Solution Approach 1:
The system performs preliminary filtering and evaluation of all received broadcast channels by measuring reception intensity (RSSI) and sorting them before presentation to the user. This pre-processing eliminates channels with poor reception quality while maintaining information about available channels.
Solution Approach 2:
The system automatically evaluates and sorts channels based on reception quality metrics without requiring user intervention to filter poor quality channels. The device serves itself by intelligently managing channel quality assessment and presentation.
3Device complexity
If the device connects to only one content providing device at a time, then connection management is simple, but the device cannot access multiple broadcast channels simultaneously
Solution Approach 1:
The system segments the connection management by maintaining separate connection states for multiple broadcast channels simultaneously. Each channel can be received and evaluated independently, allowing the device to manage multiple connections without increasing overall system complexity.
