Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If uncompressed multi-channel audio is streamed to provide high audio quality, then audio quality is improved, but bandwidth requirements increase and compatibility with existing devices decreases
Solution Approach 1:
The system changes the audio delivery parameters by introducing audio profiles with customized parameters (equalization, filter, rendering delay, volume) that are applied to compressed audio streams. This allows the same compressed stream to be optimized for different audio rendering systems without requiring uncompressed audio delivery, thus maintaining high audio quality while preserving device compatibility.
Solution Approach 2:
The patent introduces audio profiles as an intermediary layer between the compressed audio stream and the audio rendering system. The audio profile server generates profiles that mediate between the generic compressed stream and specific rendering hardware requirements, enabling customization without requiring uncompressed audio or specialized decoding capabilities.
2Device complexity
If audio is compressed to reduce bandwidth usage, then device compatibility is improved, but audio quality deteriorates
Solution Approach 1:
The system applies parameter changes by modifying audio characteristics through audio profiles that include equalization, filtering, delay, and volume adjustments. These parameter modifications are applied in the audio processing domain rather than requiring lossless audio transmission, allowing quality enhancement while maintaining compressed delivery.
Solution Approach 2:
The patent substitutes the mechanical approach of uncompressed audio transmission with a digital signal processing approach. Instead of relying on bandwidth to preserve quality, the system uses computational audio processing (equalization, filtering, rendering) to enhance quality from compressed streams.
3Manufacturing precision
If professional installation and calibration is performed to optimize audio for specific listening environments, then audio quality is improved, but cost and complexity increase
Solution Approach 1:
The system enables self-service by allowing users to select from pre-generated audio profiles that are automatically applied to their audio output. This eliminates the need for professional calibration installations, as the audio optimization is performed automatically by the audio profile server based on the user's rendering system and listening environment.
Solution Approach 2:
The patent applies preliminary action by pre-calculating and pre-generating audio profiles for various listening environments and rendering systems before the user needs them. The audio profile server creates these optimized audio parameters in advance, so users can immediately benefit from optimized audio without requiring professional installation or manual calibration.
4Manufacturing precision
If customized Android video players and local storage systems are used to achieve high quality audio, then audio quality is improved, but system complexity and cost increase
Solution Approach 1:
The patent introduces audio profiles as an intermediary service that operates between the streaming content and the user's audio system. This centralized approach replaces the need for complex customized video players and local storage systems, as the audio optimization is handled by the audio profile server rather than requiring sophisticated client-side processing and storage infrastructure.
Solution Approach 2:
The system achieves universality by providing a single audio profile delivery mechanism that works across different devices and rendering systems. The audio profile server serves multiple functions (quality optimization, compatibility adaptation, environment calibration) through a unified service, eliminating the need for multiple specialized systems.

AI summary
A system (400) for providing an audio profile for streaming video, includes an audio profile subsystem (433) that receives audio mix data and synchronizes audio data in an audio profile. A streaming service video streaming server (420) receives video data, uncompressed audio data synchronized with audio tracks, and the audio profile. An audio profile server (430) is configured to receive the audio profile and dynamic range compression descriptors to produce audio profile metadata. An audio reproduction system (410) receives audio profile metadata and listening environment parameters to adjust audio parameters based on the audio rendering system characteristics and a listening environment of the audio rendering system. The audio parameters include one or more of equalization, a filter, a rendering delay, and volume.
