Dynamic Media Asset Segmentation for Bandwidth and Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The consumption of media assets on user devices, such as smartphones and smart TVs, often requires significant network bandwidth and battery power, leading to resource constraints, especially when streaming high-quality video content.
Innovation Solution
A resource-saving system that dynamically adjusts the output parameters of media assets, such as resolution, bitrate, and frame rate, based on the content's importance and user preferences, to reduce data transfer and power consumption by switching between higher and lower quality settings for different portions of a media asset.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high-quality media assets are streamed, then media quality is improved, but network bandwidth consumption increases
Solution Approach 1:
The media asset is divided into multiple segments or portions, each with different quality levels. The system identifies important segments (e.g., action scenes, dialogue) and assigns them higher quality, while less important segments receive lower quality, thereby reducing overall bandwidth consumption while maintaining perceived quality for critical content.
Solution Approach 2:
Different portions of the media asset are assigned different quality levels based on their importance. Instead of uniformly reducing quality across the entire media asset, the system applies local quality adjustments where high quality is preserved for important segments and reduced quality is applied to less critical segments.
2Manufacturing precision
If high-quality media assets are streamed, then media quality is improved, but battery power consumption increases
Solution Approach 1:
The media playback is segmented into different quality modes corresponding to different segments of the content. The device switches between high-quality and low-quality playback modes, reducing processing load and power consumption during less critical segments while maintaining high quality during important segments.
Solution Approach 2:
Power consumption is optimized by applying different quality levels to different portions of the media asset. The system identifies which segments require high quality and which can tolerate reduced quality, thereby minimizing overall power consumption while maintaining acceptable quality for the user experience.
3Quantity of substance
If network bandwidth is reduced, then resource consumption is decreased, but media quality deteriorates
Solution Approach 1:
The media asset is segmented into important and less important portions. By reducing quality only for less important segments, the system achieves significant bandwidth reduction while preserving quality for segments that matter most to the user experience, thus minimizing perceived quality deterioration.
Solution Approach 2:
Instead of uniformly reducing quality across the entire media asset, the system applies selective quality reduction to specific segments. This allows bandwidth consumption to be reduced while maintaining high quality for critical content, thereby mitigating overall quality deterioration.
4Productivity
If display resolution is reduced, then data processing load is decreased, but output quality deteriorates
Solution Approach 1:
The media asset is divided into segments that are processed at different resolutions. Important segments are rendered at high resolution to maintain quality, while less important segments are rendered at lower resolution to reduce processing load, achieving a balance between productivity and output quality.
Solution Approach 2:
Different display resolutions are applied to different portions of the media asset based on their importance. The system maintains high resolution for critical segments where quality is paramount and reduces resolution for less critical segments to improve processing efficiency and reduce device load.

AI summary
Methods and systems for saving resources when outputting a media asset such as a video are provided. The media asset is split into a first portion with a first importance and a second portion with the second importance. The first portion is displayed with a first set of output parameters (e.g., resolution, bit rate, frame rate, display size) and the second portion is displayed with a second set of output parameters that correspond to a lower quality than the first set of output parameters (e.g., a lower resolution, a lower bit rate, a lower frame rate, a lower display size).
