Audio Data Transmission Segmentation by Frequency Band
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio data transmission methods in electronic devices are inefficient due to limitations in resource usage and variability in connection schemes, leading to potential data loss and transmission failures when transmitting audio data to external devices.
Innovation Solution
An electronic device method that divides and transmits audio data based on a period of time, considering the codec and frequency band applied to the communication link, allowing for efficient transmission by prioritizing lower frequency bands and retransmitting data as needed to ensure complete data transfer without loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If audio data is transmitted using a single frequency band allocation, then the transmission process is simple, but the audio data may be lost or transmitted improperly due to resource limitations and connection variability
Solution Approach 1:
The audio data transmission is segmented into multiple frequency bands (first frequency band and second frequency band). The processor divides the audio data and transmits different portions through different frequency bands separately, allowing for more reliable transmission by adapting to connection quality variations without requiring complete retransmission
Solution Approach 2:
The system dynamically changes transmission parameters (frequency band selection) based on connection quality. When connection quality is poor, the system switches to transmitting only in the first frequency band; when connection quality improves, it transitions to transmitting in both frequency bands, thereby adapting to varying transmission conditions
2Reliability
If the entire audio data is retransmitted upon transmission failure, then data integrity is maintained, but resource usage increases significantly
Solution Approach 1:
The audio data is segmented into different frequency band portions. When transmission failure occurs, only the specific portion that failed (in the second frequency band) is retransmitted, rather than retransmitting the entire audio data file, thereby reducing energy consumption while maintaining data integrity
Solution Approach 2:
The system performs preliminary transmission of the first frequency band data before attempting to transmit the second frequency band data. This staged approach allows the system to prepare and send critical audio data first, reducing the amount of data that may need retransmission if connection quality is poor

AI summary
Disclosed is a method for transmitting audio data in an electronic device. The electronic device can divide the audio data according to a range of a frequency band determined according to a codec applied to a communication link, and then can transmit the audio data divided in different time intervals to an external electronic device. The electronic device may preferentially transmit the audio data as the frequency band lowers, and when the transmission of audio data corresponding to the lower frequency band is successful, can transmit audio data corresponding to a higher frequency band in different time intervals.
