Fovea Tracking Video Encoding for Bandwidth Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video encoding methods, such as the H.264 standard, face challenges in providing optimal resolution and encoding accuracy for modern users who demand higher picture quality, particularly in adapting to varying viewer focus and available bandwidth.
Innovation Solution
The system employs a viewer fovea tracking generator to analyze viewer attention and adjust video encoding accuracy dynamically, prioritizing regions of viewer focus with higher resolution and color depth while reducing bandwidth usage by encoding peripheral regions less accurately, especially when transmission bandwidth is limited.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If video encoding accuracy is increased to provide higher picture quality, then manufacturing precision is improved, but loss of substance increases due to greater bandwidth consumption
Solution Approach 1:
The patent applies local quality by differentiating encoding accuracy across different spatial regions of the video frame. The system identifies a region of interest (ROI) corresponding to the viewer's foveal attention and applies high encoding accuracy only to this region, while using lower encoding accuracy for peripheral regions. This resolves the contradiction by maintaining high picture quality where the viewer actually looks (improving manufacturing precision) while reducing overall bandwidth consumption (reducing loss of substance).
Solution Approach 2:
The patent implements dynamics by making the region of interest dynamic rather than static. The ROI is continuously updated based on real-time fovea tracking data that monitors viewer eye movements and attention patterns. This allows the system to adaptively adjust where high encoding accuracy is applied, ensuring that bandwidth is always concentrated on the most relevant areas (improving manufacturing precision where needed) while minimizing overall data transmission (reducing loss of substance).
2Manufacturing precision
If video resolution is increased to meet user demands for higher picture quality, then manufacturing precision is improved, but loss of substance increases due to greater data transmission requirements
Solution Approach 1:
The patent applies local quality by implementing different resolution levels for different regions of the video frame. The region of interest, determined through fovea tracking, receives high-resolution encoding that meets user demands for picture quality (improving manufacturing precision), while peripheral regions are encoded at lower resolution (reducing loss of substance). This spatial differentiation allows the system to satisfy user quality requirements without proportionally increasing overall data transmission volume.
Solution Approach 2:
The patent implements partial action by providing high video resolution only partially - specifically, only in the region where the viewer is actually looking. Rather than encoding the entire frame at high resolution (which would excessively increase data transmission), the system applies high resolution selectively to the ROI (improving manufacturing precision where necessary) while using lower resolution elsewhere (reducing loss of substance).
