Display Audio Profile Switching for Continuous Playback and Voice Chat
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses fail to optimize audio transmission based on their operating situation, leading to user inconvenience when switching between content playback and voice chat functions.
Innovation Solution
The display apparatus includes an audio processor and a Bluetooth module that dynamically switch between audio transmission profiles, such as A2DP and HFP, to maintain audio output during voice chat events while minimizing disruption to ongoing content playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display apparatus uses a single audio transmission profile for content playback, then high-quality stereo audio can be maintained, but the apparatus cannot seamlessly switch to voice chat functions without interrupting audio output
Solution Approach 1:
The display apparatus dynamically switches between different audio transmission profiles (A2DP for stereo content playback, HFP for mono voice chat) based on the current operating situation. The processor monitors for voice chat events and transitions the Bluetooth module from A2DP to HFP profile when needed, enabling the system to adapt its audio transmission characteristics in real-time while maintaining continuous audio output through the external audio apparatus.
2Adaptability or versatility
If the display apparatus switches audio transmission profile for voice chat, then voice chat functionality is enabled, but audio quality deteriorates from stereo to mono
Solution Approach 1:
The system dynamically adjusts audio transmission quality based on functional requirements. When a voice chat event is detected, the processor switches from A2DP (stereo) to HFP (mono) profile, accepting reduced audio quality in exchange for enabling voice chat functionality. This dynamic adaptation allows the apparatus to optimize performance for the current task while maintaining the ability to switch back to high-quality stereo when voice chat is no longer active.
3Manufacturing precision
If the display apparatus maintains stereo audio transmission, then audio quality is high, but the apparatus cannot simultaneously handle voice chat audio input and output
Solution Approach 1:
The display apparatus dynamically reconfigures its audio transmission mode based on operational context. During content playback, the system uses A2DP profile for high-quality stereo output. When voice chat is initiated, the system transitions to HFP profile which supports both audio output and microphone input, enabling dual audio function capability despite the reduction to mono quality. This dynamic switching resolves the contradiction between maintaining high audio quality and enabling comprehensive audio functionality.

AI summary
A method of operating a display apparatus includes: transmitting stereo data corresponding to first audio data included in content being reproduced, to an external audio apparatus using a first audio transmission profile; changing an audio transmission profile from the first audio transmission profile to a second audio transmission profile, based on an audio-related event occurring while the stereo data is transmitted using the first audio transmission profile; and obtaining first mono audio data by selecting any one of a plurality of pieces of sound data included in the stereo data, and transmitting the first mono audio data and second mono audio data generated based on second audio data corresponding to the audio-related event, to the external audio apparatus using the second audio transmission profile.
