Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If standard audio compression and transmission methods are used in video conferencing and watch party applications, then device compatibility and ease of operation are improved, but audio quality and immersive experience deteriorate
Solution Approach 1:
The patent applies local quality by providing different audio processing treatments to different participants based on their individual environments and devices. Each participant receives customized audio parameters including spatial position, echo levels, and background noise adjustments tailored to their specific listening context, thereby maintaining high audio quality across diverse devices without requiring complex device-specific configurations.
Solution Approach 2:
The system dynamically adjusts audio parameters such as spatial position, echo, reverberation, and background noise levels based on real-time participant feedback and environmental conditions. These parameter changes enable the system to optimize audio quality for each participant individually while maintaining overall system compatibility and ease of operation across different devices and platforms.
2Manufacturing precision
If advanced audio capabilities are implemented for immersive audio environments, then audio quality and participant engagement are improved, but device complexity and processing requirements worsen
Solution Approach 1:
The patent implements self-service by enabling participants to automatically adjust their audio environments based on their own feedback and preferences. The system monitors participant reactions, environmental noise levels, and device characteristics, then autonomously adjusts audio parameters without requiring manual configuration or complex processing. This reduces device complexity while maintaining high audio quality through intelligent, adaptive processing.
Solution Approach 2:
The system incorporates feedback mechanisms where participant responses, environmental conditions, and audio performance metrics are continuously monitored and used to adjust audio parameters in real-time. This feedback loop enables the system to maintain high audio quality and immersive experiences without requiring permanently complex processing capabilities, as adjustments are made dynamically based on actual usage conditions.
3Ease of operation
If standardized background noise and acoustic properties are used across all participants, then ease of operation and system simplicity are improved, but adaptability to individual preferences and environments deteriorates
Solution Approach 1:
The patent applies dynamics by making background noise and acoustic properties adjustable and adaptive rather than fixed. The system allows background noise levels, types, and acoustic characteristics to be dynamically modified based on individual participant preferences, environmental conditions, and real-time feedback. This dynamic approach maintains system simplicity through automated adjustments while providing extensive individual customization capabilities.
4Adaptability or versatility
If individualized audio processing is provided for each participant, then adaptability and personalization are improved, but device complexity and computational requirements worsen
Solution Approach 1:
The patent applies segmentation by dividing the audio processing into modular, independent components that can be individually adjusted for each participant. Each participant's audio stream is processed separately with customized parameters for spatial position, echo, background noise, and other acoustic properties. This segmented approach enables high personalization while reducing overall computational requirements by processing each participant independently rather than requiring complex global optimization.

Data Source
AI summary
Providing a shared experience of a pre-recorded video content on video screens of devices of a plurality of participants includes presenting, on the video screens, video content corresponding to the pre-recorded video having superimposed thereon a live video feed, determining feedback of the participants to the video content, providing to the devices background noise that varies according to the feedback of the participants, and altering acoustic properties of sound for the video content provided to the devices based on acoustic properties of an emulated presentation space for the video content. Altering acoustic properties may include varying echo and reverberation levels and intensities of the sound. Altering acoustic properties may use secondary echo-generating audio reproduction sources for varying echo and emulators of reverberating surfaces for varying reverberation levels. A subset of the participants may be immersed in the emulated presentation space. The sound audio properties may be different for different participants.
