Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication devices face significant power consumption issues due to increased demands for video streaming and conferencing services, particularly with high-definition and 3D video, which is exacerbated by inefficient encoding and decoding processes, leading to reduced battery life.
Innovation Solution
Implementing energy characterization-aware multimedia streaming techniques, such as DASH, that provide metadata for power-efficient content delivery by selecting lower quality video versions and optimizing radio parameters, and using content-specific energy characterization metadata in standards like PSS and MBMS to manage power consumption dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high-definition and 3D video services are provided, then video quality is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic video quality adaptation that adjusts encoding parameters, resolution, and frame rates based on real-time power availability and network conditions. The system transitions between different quality levels dynamically, allowing high-definition and 3D video when power is sufficient, while automatically downscaling when battery levels drop or power constraints are detected.
Solution Approach 2:
The patent changes multiple video parameters including resolution, bitrate, frame rate, and encoding complexity based on power consumption requirements. By adjusting these parameters dynamically, the system can deliver high-quality video when power is abundant while reducing quality to conserve energy when power is limited, thus resolving the contradiction between video quality and power consumption.
2Adaptability or versatility
If advanced video services are implemented, then service capability is improved, but battery life is reduced
Solution Approach 1:
The system dynamically adapts service capability based on battery status and power availability. When battery life is sufficient, the system provides advanced video services including high-definition streaming and 3D content. When battery life decreases, the system automatically reduces service complexity and switches to more power-efficient modes, thereby extending usable battery life while maintaining adaptability to user needs.
Solution Approach 2:
The patent performs preliminary power characterization and service capability assessment before delivering video content. By evaluating power availability in advance and pre-selecting appropriate service levels, the system avoids situations where advanced services would deplete battery life prematurely, thus extending overall battery life while maintaining service adaptability.
3Manufacturing precision
If video quality is increased, then viewing experience is improved, but data transmission requirements increase
Solution Approach 1:
The patent dynamically adjusts video encoding parameters including resolution, bitrate, frame rate, and compression level based on network conditions and power availability. By optimizing these parameters, the system delivers high-quality video when network bandwidth is sufficient while reducing data transmission requirements when network conditions are poor or power is limited, thus resolving the contradiction between video quality and data transmission requirements.
