Multimedia Parameter Adjustment for Thermal Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current portable computing devices (PCDs) face challenges in managing thermal energy generation during multimedia processing, leading to unnecessary impacts on user experience due to 'one size fits all' throttling strategies that do not consider specific power budget allocations or interactions within a community of devices.
Innovation Solution
Implementing intelligent multimedia-based thermal power management by selectively adjusting multimedia parameter settings across a community of PCDs, sharing data on visual multimedia parameter settings to optimize power consumption and user experience, and dynamically adjusting settings to balance thermal energy generation and quality of service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If GPU voltage and frequency are throttled to reduce thermal energy generation, then thermal energy generation is mitigated, but user experience deteriorates due to slowed graphics output
Solution Approach 1:
The patent applies local quality by differentiating thermal management strategies across different applications and devices. Instead of uniform throttling, the system adjusts multimedia parameter settings selectively based on each device's thermal state, power budget, and application type, thereby reducing thermal energy generation in specific contexts without unnecessarily impacting graphics processing speed in others
Solution Approach 2:
The patent changes physical or operational parameters by adjusting multimedia parameter settings (such as video resolution, frame rate, audio quality) dynamically based on thermal conditions and power constraints. This allows the system to modulate thermal energy generation through parameter optimization rather than blunt throttling, maintaining acceptable performance while reducing heat output
2Device complexity
If a one size fits all throttling strategy is used to manage thermal energy, then thermal management is simplified, but power budget allocation for specific applications is ignored
Solution Approach 1:
The patent segments the thermal management approach by dividing the overall power budget into application-specific allocations and applying different throttling strategies to different applications based on their thermal impact and user experience requirements. This segmentation allows tailored power management for each application rather than uniform treatment
Solution Approach 2:
The system dynamically adjusts thermal management policies in real-time based on changing conditions such as temperature, power budget availability, and application state. This dynamic adaptation enables the system to respond to specific thermal situations and power constraints, making the thermal management strategy flexible rather than static
3Productivity
If multimedia parameter settings are not optimized across companion devices, then device independence is maintained, but network bandwidth consumption increases
Solution Approach 1:
The patent implements feedback mechanisms where each device shares its thermal state, power budget status, and multimedia parameter settings with companion devices. This feedback loop enables devices to adjust their encoding and decoding parameters based on peer conditions, optimizing network bandwidth usage while maintaining device independence through coordinated optimization
Data Source
AI summary
Various embodiments of methods and systems for balancing user experience in a multimedia conferencing community are disclosed. An exemplary embodiment envisions a portable computing device (“PCD”) receiving data indicative of one or more visual multimedia parameter settings in a companion PCD of the community. Based on the received data, the PCD may determine an adjustment to the settings of one or more of its own visual multimedia parameters such that a multimedia output in the form of a data packet stream is adjusted. In this way, the PCD may conserve power consumption by avoiding unnecessary multimedia workload processing for encoding a multimedia output that would not benefit the quality of service (“QoS”) delivered by the companion PCD. Additionally, by optimizing the quality of the multimedia output in view of the companion device parameter settings, the PCD may allocate more of its power budget to improving its own QoS level.
