Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transmission methods between computing devices require specialized hardware and communicative pairing, which can be cumbersome and inefficient, especially in scenarios where a shared computing network is not available or practical.
Innovation Solution
The use of audio transmissions to send data between devices, where data is interleaved and modulated into audio symbols, allowing for transmission without the need for specialized hardware or pairing, using conventional devices like speakers and microphones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If specialized hardware and communicative pairing are used for data transmission, then transmission reliability is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent replaces specialized communication hardware (Bluetooth modules, Wi-Fi cards) with conventional audio hardware (speakers and microphones). Data is transmitted by modulating audio signals that can be played through speakers and captured by microphones, eliminating the need for dedicated wireless communication components while maintaining transmission capability.
Solution Approach 2:
The patent introduces audio signals as an intermediary medium for data transmission. Instead of direct device-to-device communication, data is embedded within audio signals that serve as a carrier, allowing transmission through the audio environment without requiring specialized communication protocols or pairing mechanisms.
2Reliability
If specialized hardware and pairing protocols are implemented, then data security is improved, but ease of operation and setup time worsen
Solution Approach 1:
The system performs self-identification and self-synchronization through the audio environment. Devices automatically detect audio transmissions, extract embedded data, and establish communication without requiring manual pairing, device discovery, or user intervention. The audio signals themselves carry the necessary information for devices to identify and connect with each other.
3Speed
If data is transmitted without interleaving, then transmission speed is improved, but reliability against audio interference deteriorates
Solution Approach 1:
The patent divides the data payload into multiple segments and interleaves them with each other and with supplementary data. This segmentation distributes the impact of temporal interference across multiple data segments, allowing error correction and recovery even when portions of the transmission are corrupted by audio interference from other sources.
Solution Approach 2:
The system incorporates error checking codes and supplementary data before transmission occurs. These protective elements are embedded within the interleaved data structure in advance, providing a buffer against potential interference. When interference occurs, the pre-included error correction mechanisms can recover the original data without requiring retransmission.

AI summary
Methods and systems for improved transmission of data using audio signals are provided. In one embodiment, a method is provided that includes receiving data for transmission within an audio environment and interleaving the data. The interleaved data may be modulated into multiple audio symbols to form an audio transmission. An audio signal may be generated based on, and the audio signal may be transmitted within the audio environment. In another embodiment, a method is provided that includes detecting an audio transmission within an audio signal from an audio environment. The audio transmission may be extracted, and a data payload of the audio transmission may be identified. The data payload may be deinterleaved (e.g., according to a predetermined interleaving protocol). The deinterleaved data may be decoded, allowing data to be extracted.
