Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If compressive encoding is applied to reduce data size, then storage capacity and bandwidth requirements are reduced, but image quality may be degraded
Solution Approach 1:
The patent applies filtering operations before encoding to pre-process the video data. By filtering the video data beforehand, the system removes noise and artifacts that would otherwise require more aggressive compression, thereby maintaining image quality while still achieving data reduction through subsequent encoding processes
2Manufacturing precision
If filtering is applied to improve image quality, then noise and artifacts are reduced, but processing time and complexity increase
Solution Approach 1:
The patent implements selective filtering that applies processing only to specific regions or frames where it is most beneficial. Rather than filtering all video data uniformly, the system identifies areas requiring quality enhancement and applies filtering selectively, reducing overall processing time while maintaining image quality where it matters most
3Manufacturing precision
If additional encoding information is used to enhance quality, then image fidelity is improved, but bit rate increases
Solution Approach 1:
The patent dynamically adjusts encoding parameters based on the filtered video data characteristics. By changing encoding parameters adaptively rather than using fixed settings, the system achieves high image fidelity without unnecessarily increasing bit rate, optimizing the balance between quality and data size

AI summary
A video encoding apparatus includes a motion estimation module, an information providing module, a filtering module, a motion compensation module, and a converting module. The motion estimation module performs a plurality of modes of motion estimations on macro-blocks included in an input frame and provides a motion-estimated frame which conforms to a predetermined standard. The information providing module receives motion vectors and mode information of the plurality of modes of motion estimations to provide an encoding information signal. The filtering module filters the motion-estimated frame to provide a filtered frame based on the encoding information signal. The motion compensation module performs motion compensation on the filtered frame to provide a motion-compensated frame. The converting module performs a spatial conversion on the motion-compensated frame.
