Device Driver Interface for Time-Sensitive Audio Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems, such as Bluetooth devices, require developers to have knowledge of both audio and wireless communication drivers, leading to complexity and inefficiency, as audio data often bypasses standard host controller interfaces, necessitating a separation of audio and wireless communication drivers for independent development.
Innovation Solution
A device driver interface is created to channel audio data separately from wireless communication data, allowing developers to focus on either audio or wireless communication development independently, with the interface managing communication between the two drivers and limiting information flow to only what is relevant for each driver's functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If audio data and wireless communication data share the same transmission channel, then the system structure is simpler, but the time-sensitive audio data transmission quality deteriorates due to interference and processing delays
Solution Approach 1:
The patent divides the data transmission channel into separate pathways: a first channel for audio data and a second channel for wireless communication data. This segmentation allows audio data to bypass the Bluetooth HCI and other components that process non-audio data, ensuring time-sensitive audio transmission quality while maintaining manageable system structure through dedicated channels.
2Productivity
If audio driver and wireless communication driver are integrated, then the development process is more efficient, but the developer must master both audio and wireless communication protocols increasing skill requirements
Solution Approach 1:
The patent separates the audio driver from the wireless communication driver, allowing each to be developed independently by specialists. The audio driver focuses solely on audio data handling while the wireless communication driver manages Bluetooth protocols. This segmentation enables developers to master one domain deeply without being overwhelmed by requiring knowledge of both audio and wireless communication stacks.
Solution Approach 2:
The patent introduces a device driver interface as an intermediary layer between the audio driver and wireless communication driver. This interface provides standardized communication protocols that allow the separated drivers to cooperate without requiring the developers to understand both audio and wireless communication internals, thus maintaining development efficiency while reducing skill requirements.
3Speed
If the audio driver communicates directly with the wireless communication driver, then the information flow is more direct, but unnecessary information increases processing overhead and reduces performance
Solution Approach 1:
The patent implements a device driver interface as an intermediary that mediates communication between the audio driver and wireless communication driver. This interface filters and selects only the necessary information to pass between drivers, eliminating unnecessary data transfer and reducing processing overhead while maintaining direct and efficient information flow for critical audio-related parameters.
Data Source
AI summary
One or more techniques and/or systems are provided for communicating between two or more drivers respectively controlling and/or managing different channels through which data is transferred between a wireless communication device and a computer system and/or between a controller of the computer system and an application of the computer system. Typically, at least one of the channels is configured to transmit time sensitive data (e.g., such as audio data) while another channel is configured to transmit time insensitive data (e.g., such as call control data). A device driver interface may be configured to provide a medium through which the two or more drivers can communicate. The techniques and/or systems find particular application with respect to Bluetooth headsets used in combination with a computer system comprising a system on chip architecture, but other applications are also contemplated.
