Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional video coding technologies are used, then coding efficiency is maintained at baseline levels, but coding quality cannot be improved adaptively based on video content type, boundary type, and gradient information
Solution Approach 1:
The patent implements dynamic control of coding schemes by determining enablement flags based on video content type, boundary type, and gradient information. The system adaptively adjusts coding parameters according to local video characteristics, transitioning from static to dynamic coding scheme selection to improve coding quality while maintaining efficiency.
Solution Approach 2:
The patent applies different coding schemes to different regions of video units based on local characteristics such as boundary types and gradient information. By analyzing specific regions and applying appropriate coding methods locally, the system achieves improved coding quality without uniformly increasing complexity across the entire video stream.
2Manufacturing precision
If adaptive control of coding schemes is implemented based on multiple parameters, then coding quality is improved, but system complexity increases
Solution Approach 1:
The patent segments the video processing into distinct analysis stages: determining video content type, analyzing boundary types, calculating gradient information, and selecting coding schemes. This segmentation of the coding control process into modular steps manages system complexity by breaking down the adaptive control mechanism into manageable, independent functions.
Solution Approach 2:
The patent changes key parameters such as enablement flags and coding mode selections based on analyzed video characteristics. By modifying specific coding parameters adaptively rather than redesigning the entire coding system, the patent improves coding quality while minimizing the increase in overall system complexity.
