Dynamic Playback Function Management for CPU Load Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current playback devices experience CPU overload due to excessive processor resource consumption from various multimedia content playback functions, leading to issues like pixelation, slowdowns, or content cutoff, especially when rendering live or on-demand content simultaneously with menus.
Innovation Solution
The method dynamically manages the availability of playback functions on a playback device by varying their rendering based on processor load, content type, and execution context, ensuring only necessary functions are active to prevent CPU overload, such as rendering only essential functions when load exceeds 80% and deactivating less critical functions to maintain smooth content rendering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple playback functions are rendered simultaneously on the screen, then user interface functionality is improved, but processor resource consumption increases leading to CPU overload
Solution Approach 1:
The patent implements dynamic management of playback function availability based on execution context and processor load conditions. Functions are activated or deactivated in real-time according to system state, transforming the static function set into a dynamic configuration that adapts to current resource availability and playback requirements.
Solution Approach 2:
The system changes the availability parameter of playback functions based on execution context (live vs. VOD content) and processor load thresholds. When load exceeds 80%, the system modifies which functions are available, changing the operational parameters of the player to maintain performance while preserving essential functionality.
2Ease of operation
If playback functions are rendered in the background simultaneously with content, then user access to functions is improved, but content rendering quality deteriorates due to CPU overload
Solution Approach 1:
The patent ensures continuous availability of essential playback functions while managing processor load. By dynamically adjusting function availability rather than completely disabling functions during high load, the system maintains continuous useful action for critical operations while preventing quality deterioration in content rendering.
Solution Approach 2:
The system implements feedback mechanisms by monitoring processor load and execution context continuously. Based on this feedback, the system adjusts function availability in real-time, creating a closed-loop control system that responds to changing conditions and maintains optimal balance between accessibility and rendering quality.
3Ease of operation
If all playback functions are made available at all times, then user convenience is improved, but system performance deteriorates due to excessive CPU load
Solution Approach 1:
The patent segments the set of playback functions into different availability groups based on execution context. Different function subsets are made available for live content versus VOD content, and further adjusted based on processor load conditions. This segmentation allows the system to provide appropriate functionality for each content type without overwhelming the processor.
Solution Approach 2:
The system applies partial action by making only the necessary functions available rather than all functions simultaneously. When processor load exceeds thresholds, the system deliberately limits function availability to essential operations, accepting that not all functions will be accessible at all times in exchange for maintaining overall system performance and content rendering quality.
