Audio Mixing Priority Arbitration for Urgent Alert Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio mixing devices may delay the output of important audio information, leading to potential delays in user treatment, especially when both earlier and later audio information require urgency.
Innovation Solution
An audio mixing device with a mixing circuit and arbitration circuit that prioritizes and arbitrates the input of audio data based on urgency, ensuring that audio data with high urgency is output immediately while data with low urgency is delayed if necessary, using a channel-priority setting table and gain setting to manage audio playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If audio data is processed in strict sequential order, then output order is maintained, but high urgency audio data may be delayed when low urgency audio data is being processed
Solution Approach 1:
The patent segments audio data into multiple priority levels (first priority/high urgency and second priority/low urgency). The arbitration circuit divides the audio data processing into separate priority channels, allowing high urgency audio data to be arbitrated and output independently from low urgency audio data, thus preventing delays caused by sequential processing of all audio data regardless of urgency.
2Productivity
If multiple audio data are mixed simultaneously, then system throughput is improved, but critical audio information may be obscured or delayed
Solution Approach 1:
The patent applies local quality by assigning different processing characteristics to different portions of audio data based on their urgency. High urgency audio data receives preferential arbitration and is processed with higher priority, ensuring timely delivery. Low urgency audio data is processed with normal priority. This localized differentiation in processing quality ensures critical audio information is delivered promptly while maintaining overall system throughput.
3Productivity
If low urgency audio data is processed first, then system efficiency is maintained, but user response time for critical alerts is increased
Solution Approach 1:
The patent implements preliminary action by pre-classifying audio data into priority levels before processing. The arbitration circuit is configured in advance to recognize and prioritize high urgency audio data. When audio data arrives, the arbitration circuit immediately identifies high urgency data and arbitrates it for preferential processing, ensuring that critical audio information is processed and delivered without delay, thus minimizing user response time for critical alerts.

AI summary
An audio mixing device includes: a mixing circuit configured to mix a plurality of pieces of audio data to be played included in first to p-th audio data among first to n-th audio data when the plurality of pieces of audio data are input in a same period, and output a mixing signal, n being an integer of three or more and p being an integer equal to or larger than two and less than n; and an arbitration circuit configured to arbitrate input of (p+1)-th to n-th audio data among the first to n-th audio data to the mixing circuit.
