Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication modules (WiFi) are used for audio transmission to avoid complex cable wiring, then ease of operation is improved, but reliability deteriorates due to shielding and interference from electronic devices and decorations on stage
Solution Approach 1:
The patent applies preliminary action by pre-sorting audio data packets based on timestamps before transmission and processing. The audio playing device sorts packets in advance according to timestamp order, and the processing device extracts and processes packets in the correct sequence, ensuring timely audio playback even in complex electromagnetic environments. This preliminary organization of data prevents transmission issues from affecting playback quality.
2Reliability
If multiple wireless communication channels are used to improve transmission stability, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing audio data into multiple packets with timestamps and distributing them through different wireless communication channels. The receiving device segments the reception process into: obtaining packets from multiple channels, sorting by timestamp, extracting valid packets, and processing in sequence. This segmentation allows multiple channels to be used effectively without significantly increasing overall system complexity.
3Speed
If audio data packets are processed in real-time to improve timeliness, then speed is improved, but manufacturing precision deteriorates due to packet loss and transmission instability
Solution Approach 1:
The patent applies feedback by implementing a timestamp-based validation and reordering mechanism. The receiving device checks packet timestamps, identifies missing or out-of-order packets, and processes only valid packets in the correct sequence. This feedback loop ensures that even if some packets are lost or arrive out of order during fast transmission, the audio quality and timing precision are maintained.
Data Source
AI summary
An audio data processing method, an audio data processing apparatus, a computer readable storage medium, and an electronic device, which are suitable for a stage, are provided. The audio data processing method includes steps of obtaining audio data packets sent by wireless communication modules of the audio playing device, and extracting a first timestamp from audio data package names of the audio data packets; determining whether each of first package names corresponding to a preset primary cache queue includes the first timestamp; and inserting the audio data packets into the preset primary cache queue if each of the first package names corresponding to the preset primary cache queue does not include the first timestamp; taking an earliest value in the timestamps corresponding to each of the first package names corresponding to the preset primary cache queue as a second timestamp.
