Audio Data Segmentation for Simultaneous Service Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices can only have one service, such as a voice call service, utilize audio data from a microphone at a time, limiting the flexibility of service control as other services, like control services, cannot access the audio data simultaneously.
Innovation Solution
An electronic device transmits audio data captured by a microphone to both the application service and the control service, allowing the control service to control the device and the application service to perform multimedia interactions, using separate audio channels and backup data processing to manage keyword triggers for controlling the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If only one service can obtain audio data from the microphone at one time, then the system is simple to manage, but the control service cannot obtain audio data when an application service is in operation, resulting in poor service control flexibility
Solution Approach 1:
The patent segments the audio data transmission by creating separate audio channels: a first audio channel for transmitting audio data to the control service, and a second audio channel for transmitting audio data to the application service. This segmentation allows both services to simultaneously access audio data through independent channels, resolving the conflict between service control flexibility and system simplicity.
2Adaptability or versatility
If audio data is transmitted to both control service and application service simultaneously, then service control flexibility is improved, but the system requires separate audio channels and backup data processing increasing complexity
Solution Approach 1:
The control service acts as an intermediary in the audio data transmission architecture. The microphone transmits audio data to the control service via the first audio channel, and the control service can then forward relevant audio data to the application service through the second audio channel. This intermediary role allows coordinated data distribution while maintaining systematic management.
Solution Approach 2:
The patent implements a backup data mechanism where the control service maintains backup audio data that can be transmitted to the application service. This copying approach allows the application service to access audio data without requiring direct access to the microphone, simplifying the overall data management architecture while enabling simultaneous service operation.
3Measurement precision
If the control service processes all audio data for keyword identification, then control accuracy is improved, but the application service cannot perform multimedia interactions simultaneously
Solution Approach 1:
The patent segments the audio data processing responsibilities by creating separate audio channels for different services. The control service processes audio data through the first audio channel for keyword identification and device control, while the application service receives audio data through the second audio channel for multimedia interactions. This segmentation enables both services to simultaneously process audio data with their respective functions.
Solution Approach 2:
The control service is designed with multi-functionality, serving both as the primary audio data receiver for keyword identification and as a data forwarder to the application service. This universal role allows the control service to maintain high keyword identification accuracy while simultaneously enabling the application service to perform multimedia interactions without conflict.
