Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video timing signals are converted to different formats, then compatibility with various display standards is improved, but the complexity of the timing signal processing system increases
Solution Approach 1:
The timing signal processing device is designed to handle multiple video timing standards (HVGA, VGA, SVGA, XGA, etc.) through a single unified processing architecture. The system uses universal parameter extraction and conversion mechanisms that can process different input timing formats and output corresponding target timing signals, eliminating the need for separate processing circuits for each standard.
Solution Approach 2:
The system converts video timing signals by extracting key parameters (horizontal sync period, vertical sync period, active display period, etc.) from the input signal and transforming these parameters according to the target display standard requirements. The conversion process involves mathematical relationships between source and target parameters, such as calculating target horizontal sync period based on the ratio of active display periods, thereby achieving format conversion through parameter transformation rather than complex circuit redesign.
2Speed
If timing signal conversion is performed in real-time, then display responsiveness is improved, but the processing time and computational load increase
Solution Approach 1:
The system pre-calculates and stores the conversion relationships between different video timing standards. When a timing conversion is needed, the system directly applies the pre-determined conversion formulas and parameter ratios rather than performing complex real-time calculations. This preliminary preparation of conversion data enables fast, real-time timing signal adaptation without significant processing delays.
Solution Approach 2:
The patent replaces complex mechanical or hardware-based timing conversion mechanisms with software-based parameter calculation and signal generation. By using programmable logic and mathematical computations to generate timing signals, the system achieves faster and more flexible conversion compared to traditional hardware timing generators, reducing processing time while maintaining real-time performance.
