External Audio State Feedback for Display Playback Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses struggle to provide consistent and high-quality audio playback due to incompatibilities between different external audio output devices, leading to abnormal sound playback and inefficient resource utilization.
Innovation Solution
The display apparatus includes a processor that adjusts audio states and formats to match the capabilities of connected external audio output devices, employing sound channel switching and audio data processing methods to ensure compatibility and quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display apparatus supports multiple external audio output devices with different capabilities, then the adaptability and versatility are improved, but the device complexity increases due to the need for compatibility management and audio state synchronization
Solution Approach 1:
The display apparatus actively requests audio state information from external audio output devices and uses this feedback to adjust audio playback parameters. The system sends requests for audio state (such as mute state, volume level) and adjusts playback based on the returned information, creating a closed-loop control system that ensures compatibility without requiring complex pre-configuration
Solution Approach 2:
External audio output devices automatically report their own audio state (mute state, volume level) to the display apparatus when requested. This self-service mechanism allows the display apparatus to adapt to different devices without manual intervention or complex compatibility management, as each device provides its own status information on demand
2Measurement precision
If the display apparatus actively requests and adjusts audio state parameters, then the measurement precision and control accuracy are improved, but the loss of time increases due to additional communication overhead
Solution Approach 1:
The display apparatus sends audio state requests and adjusts playback parameters in advance before actual audio playback begins. By proactively obtaining audio state information (such as checking if the device is muted or its volume level) before playback, the system ensures accurate control without causing delays during the actual media playback, as the communication overhead occurs during the setup phase

AI summary
The disclosure provides a display apparatus and a method. The display apparatus includes a display, a communicator, an external device interface, a memory and a processor. The processor is configured for: receiving a command for adjusting an audio state of an external audio output device in connection with the display apparatus; determining a target audio state to which the external audio output device needs to be adjusted by parsing the command; sending, to the external audio output device, an audio state adjusting instruction for adjusting the audio state to adjust a current audio state of the external audio output device to the target audio state and an instruction for requesting audio state to request the external audio output device to send the target audio state to the display apparatus; receiving the target audio state returned from the external audio output device and displaying the target audio state.
