Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If spatial audio features are enabled in the first configuration, then audio quality is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic configuration switching between first and second configurations based on participant device states. The system transitions from a first configuration with spatial audio features enabled to a second configuration with spatial features disabled when power saving is needed, and switches back when full audio quality is required. This dynamic adaptation resolves the contradiction by making audio quality and power consumption trade-offs context-dependent rather than fixed.
Solution Approach 2:
The patent changes key parameters of the audio stream configuration including spatial audio enablement, bit rate, and sample rate. By modifying these parameters between first and second configurations, the system can adjust the balance between audio quality and power consumption. Specifically, disabling spatial audio features and adjusting encoding parameters in the second configuration reduces power consumption while maintaining basic audio quality.
2Ease of operation
If spatial audio features are enabled, then audio experience is improved, but device power consumption increases
Solution Approach 1:
The system dynamically adjusts the audio configuration based on real-time conditions including participant device power states. When a participant device indicates power save mode, the system switches to a second configuration that disables spatial audio features, thereby reducing power consumption while maintaining acceptable audio experience through alternative configurations.
Solution Approach 2:
The patent applies different quality levels to different participants in the communication session. Instead of uniformly providing high-quality spatial audio to all participants, the system selectively applies the first configuration with spatial features only to participants who need or request high audio quality, while providing a second configuration with reduced features to participants in power save mode. This local differentiation resolves the contradiction by providing high audio experience only where necessary.
3Use of energy by moving object
If audio stream configuration is optimized for power saving, then power consumption is reduced, but audio characteristics may deteriorate
Solution Approach 1:
The system employs feedback mechanisms where participant devices send indications of their power save mode status to the audio processing system. Based on this feedback, the system dynamically selects between first and second configurations. The feedback loop ensures that audio characteristics are maintained within acceptable ranges by switching to power-saving configurations only when participants indicate they are in power save mode, rather than unconditionally reducing audio quality.
Solution Approach 2:
The patent creates a composite audio configuration strategy that combines elements of both high-quality and power-saving configurations. The second configuration for power save mode maintains essential audio characteristics while disabling only the most power-intensive spatial features. This composite approach ensures that even in power-saving mode, basic audio characteristics remain acceptable, resolving the contradiction between power reduction and audio quality maintenance.

AI summary
Examples of the disclosure relate to power saving for audio streams during communication sessions. In examples an apparatus is configured to provide an audio stream to a participant device during a communication session with at least the participant device wherein the audio stream is provided in a first configuration and the first configuration provides one or more audio characteristics. The apparatus receives an indication from the participant device that the participant device is to enter or has entered a power save mode and determines a second configuration for the audio stream. The second configuration reduces power consumption of the participant device and maintains at least one of the one or more audio characteristics of the first configuration within a target range. The apparatus is also configured to switch the configuration used for the audio stream from the first configuration to the second configuration.
