Vehicle Audio Stream Switching by Category and Terminal Location
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current audio stream processing methods in vehicles lack flexibility, as they automatically switch playback between vehicles and terminals based on connection states without considering the type of audio stream, leading to inflexible entertainment options and potential privacy issues.
Innovation Solution
An audio stream processing method that determines whether to switch playback based on specific categories of audio streams, allowing for flexible switching between vehicles and terminals, and uses audio signals to detect the terminal's location relative to the vehicle, enabling continuous playback and privacy management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the play device is automatically switched based on connection state, then the switching process is simple, but the flexibility of audio stream playback is poor
Solution Approach 1:
The patent changes the parameter of play device selection from automatic connection-based switching to category-based switching. The terminal device categorizes audio streams into first category (local playback preferred) and second category (vehicle playback preferred), and allows users to select play devices based on audio category rather than automatically switching based on connection state, thereby improving flexibility while maintaining simple operation
Solution Approach 2:
The patent segments audio streams into different categories (first category and second category) based on playback requirements. This segmentation allows different switching strategies to be applied to different audio types, improving overall system flexibility without complicating the user interface
2Object-affected harmful factors
If the terminal device switches back to local playback when disconnected, then privacy is protected, but entertainment continuity is interrupted
Solution Approach 1:
The patent changes the default playback behavior from automatic local playback upon disconnection to category-based playback selection. Audio streams in the second category continue playing through the vehicle even when disconnected, maintaining entertainment continuity, while the terminal device can still control first category audio locally to protect privacy
Solution Approach 2:
The patent segments audio playback into two independent pathways: first category audio plays locally on the terminal device for privacy protection, while second category audio continues through the vehicle for entertainment continuity. This segmentation resolves the contradiction by allowing both privacy protection and continuous playback simultaneously
3Ease of operation
If all audio streams are treated the same way, then the system is simple to operate, but user experience is poor
Solution Approach 1:
The patent changes the system from treating all audio streams uniformly to categorizing them into different types with different playback behaviors. The terminal device automatically categorizes audio streams based on their characteristics, and provides different playback options for each category, improving user experience without requiring complex manual configuration
Solution Approach 2:
The patent creates a universal categorization system that automatically applies to all audio streams regardless of source or type. The same category-based switching logic handles music, videos, calls, and other audio types uniformly, maintaining system simplicity while adapting to diverse user needs through intelligent categorization

AI summary
Embodiments relate to audio stream and address processing methodologies, which is applicable to exemplary methods and devices including a first terminal device. The first terminal device establishes a connection to the vehicle, and switches a play device of audio streams in a first category and a second category from the first terminal device to the vehicle; and in a process in which the first terminal device and the vehicle are in a connected state, upon detecting that the first terminal device is moved from the inside of the vehicle to the outside of the vehicle, obtains a target category corresponding to the target audio stream being played by the vehicle. The target audio stream is generated by the first terminal device and sent to the vehicle. The vehicle continues to play the target audio stream if the target category is the first category.
