Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless transmission of audio data between a display device and an electronic apparatus is susceptible to network interference, affecting the stability and quality of audio signal output.
Innovation Solution
The electronic apparatus adjusts the format of audio data based on the network state between the display device and itself, using different codecs and sampling rates to ensure stable and high-quality audio transmission to an audio output device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless transmission is used to transmit audio data from display device to electronic apparatus, then ease of connection is improved, but transmission stability deteriorates due to network interference
Solution Approach 1:
The electronic apparatus dynamically changes transmission parameters including codec type (e.g., MAT, DD+, LC3), sampling rate (48kHz, 24kHz, 16kHz), and bitrate based on real-time network state assessment. When network quality is good, higher quality codecs and sampling rates are used; when network quality degrades, the system switches to more compressed formats with lower bitrates to maintain stable transmission.
2Manufacturing precision
If audio data is transmitted in high quality format, then audio output quality is improved, but network transmission stability deteriorates
Solution Approach 1:
The system dynamically adjusts audio data format parameters including codec selection, sampling rate, and bitrate based on real-time network conditions. The electronic apparatus continuously monitors network state and adapts transmission parameters to maintain both quality and stability, switching between high-quality formats (MAT, DD+) and more compressed formats (LC3) as needed.
3Reliability
If audio data format is adapted to network state, then transmission stability is improved, but device complexity increases
Solution Approach 1:
The electronic apparatus implements a feedback mechanism where it continuously monitors network state (packet loss rate, latency, bandwidth) and uses this information to dynamically adjust audio transmission parameters. The system assesses network quality in real-time and automatically selects appropriate codecs and sampling rates, creating a closed-loop control system that maintains stable transmission without manual intervention.

AI summary
An electronic device is disclosed. The present electronic device comprises: a first communication interface; a second communication interface for wirelessly communicating with a display apparatus; and one or more processors that, when audio data is received from the display apparatus through the second communication interface, transmit the audio data to a sound output apparatus through the first communication interface. A format of the audio data received from the display apparatus is determined on the basis of a network state between the display apparatus and the electronic device. The one or more processors change the format of the audio data when the format of the audio data received from the display apparatus is different from a format for transmitting the audio data to the sound output apparatus, and transmit the audio data having the changed format to the sound output apparatus through the first communication interface.
