Engineering Contradiction Analysis
1Productivity
If automatic calculation method is used for video processing, then processing speed is improved, but video quality deteriorates due to lack of targeted processing
Solution Approach 1:
The encoder performs preliminary analysis of video characteristics (complexity, motion, texture, color distribution) and pre-determines the most suitable processing algorithms and parameters before transmission. This allows the decoder to directly apply optimized processing without real-time calculation, achieving both high speed and high quality.
Solution Approach 2:
The system establishes a feedback mechanism where the encoder analyzes video characteristics and sends control information (algorithm selection and parameter settings) to the decoder. This closed-loop approach ensures the processing method adapts to different video content while maintaining efficient execution at the decoder side.
2Device complexity
If same processing method is applied to all videos, then device complexity is reduced, but video quality deteriorates due to lack of adaptability
Solution Approach 1:
Different processing algorithms and parameters are applied to different regions or types of video content based on local characteristics. The system analyzes video complexity, motion, texture, and color distribution to determine appropriate processing methods for each video segment, achieving localized optimization without increasing overall system complexity.
Solution Approach 2:
The system dynamically changes processing parameters (filter type, window size, enhancement strength) based on video characteristics analyzed by the encoder. By transmitting parameter information along with video data, the decoder can adapt processing methods to different video content without requiring multiple complex processing paths.
3Manufacturing precision
If video processing algorithm information and parameter information are transmitted, then video quality is improved, but transmission bandwidth consumption increases
Solution Approach 1:
The system extracts only the essential control information (algorithm selection identifiers and key parameters) from the complex processing logic and transmits only this condensed information along with video data. This extraction approach minimizes additional transmission overhead while preserving the ability to perform targeted high-quality processing at the decoder.
