Wireless Audio Transmission Device Dynamic Codec Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication technologies face challenges in efficiently compressing and transmitting high-quality audio signals due to the lack of compatibility between transmitting and receiving devices, leading to increased access time during pairing and suboptimal use of new codec function modules.
Innovation Solution
A transmitting device that receives function module information from a receiving device during pairing, encodes data signals based on this information, and selects appropriate encoding modes or codecs to ensure compatibility and efficient transmission, including switching to lower bandwidth codecs when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a new function module is added to the codec supported by the transmitting device or receiving device, then the compression efficiency and sound quality are improved, but the compatibility between transmitting device and receiving device deteriorates
Solution Approach 1:
The patent implements dynamic codec selection and function module activation based on real-time detection of receiving device capabilities. The transmitting device dynamically adjusts which function modules are activated and which codec is used, transitioning between different compression efficiency levels depending on the receiving device's supported features, thereby resolving the contradiction between advanced compression and compatibility.
Solution Approach 2:
The patent changes the operational parameters of the codec system by selectively activating or deactivating specific function modules based on the receiving device's capabilities. This parameter adjustment allows the system to operate at optimal compression efficiency when the receiving device supports advanced modules, while automatically falling back to basic modules for compatibility when needed.
2Manufacturing precision
If a new codec is generated to support expanded function modules, then the compression capability is improved, but the access time increases due to increased pairing information exchange
Solution Approach 1:
The patent performs preliminary detection of the receiving device's supported function modules during the pairing process itself, rather than requiring separate negotiation steps. By embedding the capability detection in the initial pairing information exchange, the system avoids additional access time while still enabling optimal codec selection and function module activation.
Solution Approach 2:
The patent merges the codec capability negotiation with the existing pairing process by incorporating function module support information into the pairing information exchange. This consolidation eliminates the need for separate capability detection steps, reducing access time while maintaining full compression capability when supported.
3Adaptability or versatility
If function module information is exchanged during pairing, then the compatibility is improved, but the pairing process complexity increases
Solution Approach 1:
The patent makes the pairing process universal by designing it to simultaneously accomplish device pairing and codec capability detection. The same pairing information exchange structure is used to convey both connection establishment data and function module support information, eliminating the need for separate complexity-inducing negotiation phases while improving compatibility.
