Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple video interfaces are used to transmit high-definition and ultra-high-definition videos, then the data transmission capacity is improved, but the synchronization difficulty increases
Solution Approach 1:
The input images are divided into multiple image blocks, with each writing controller responsible for obtaining input data of one image block. This segmentation allows parallel processing of video data from multiple interfaces while maintaining synchronization through coordinated frame address management.
Solution Approach 2:
A memory is introduced as an intermediary buffer between multiple writing controllers and reading controllers. The memory stores video data with frame addresses, enabling synchronization by allowing reading controllers to obtain data with frame addresses spaced by a predetermined quantity, thus decoupling the timing requirements of different interfaces.
2Adaptability or versatility
If image segmentation mode conversion is performed between input and output data, then the adaptability to different interfaces is improved, but the processing complexity increases
Solution Approach 1:
The processing system is divided into independent writing controllers and reading controllers, each handling specific image blocks. This segmentation of control functions simplifies the overall complexity by allowing each controller to independently manage its assigned segment without requiring complex coordination logic.
Solution Approach 2:
The system changes the parameter of frame address spacing by a predetermined quantity to achieve image segmentation mode conversion. By adjusting this parameter, the system can adapt between different segmentation modes (e.g., interlaced vs. progressive scan) without requiring complex conversion logic.
3Reliability
If frame rate conversion is performed for videos from different interfaces, then the synchronization capability is improved, but the processing time increases
Solution Approach 1:
The system performs preliminary frame address spacing by a predetermined quantity in the memory before actual data reading. This preliminary action prepares the data in advance, allowing reading controllers to efficiently retrieve synchronized data without requiring complex real-time frame rate conversion during the reading phase.
