Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the video stream is processed using clock interruption of field synchronization signal to ensure sharp and smooth playback, then the video playback quality is improved, but the processing flow becomes complicated and frames may become out of order logically
Solution Approach 1:
The patent extracts the frame attribute information configuration from the complex clock interruption processing flow. By directly acquiring frame attribute information from the video stream and configuring it to registers without going through the complicated field synchronization signal interruption process, the solution simplifies the processing flow while maintaining playback quality.
Solution Approach 2:
The patent performs preliminary acquisition of frame attribute information before video playback processing. By pre-acquiring and storing frame attribute information from the video stream, the system avoids the need for complex real-time extraction during clock interruption, thereby simplifying the processing flow while ensuring frames are processed in correct order.
2Productivity
If a large amount of video stream is processed using clock interruption of field synchronization signal, then the video stream processing capacity is improved, but the frames of video data become out of order logically
Solution Approach 1:
The patent implements a feedback mechanism by acquiring frame attribute information that includes timing and sequence data, then using this information to verify and maintain frame order during processing. The system feedbacks on frame sequence integrity, ensuring that even when processing large amounts of video data, frames remain in logical order.
Solution Approach 2:
By preliminarily acquiring and organizing frame attribute information including sequence identifiers before processing, the system establishes a framework that maintains frame order consistency throughout high-volume processing, preventing logical disorganization of frames.
3Productivity
If the processing result is stored in the kernel driver, then the processing efficiency is improved, but the user layer cannot invoke the processing result and functions are restricted
Solution Approach 1:
The patent creates a dual-purpose mechanism where frame attribute information is processed efficiently in the kernel driver while simultaneously being made accessible to the user layer through standardized interfaces. This multi-functional approach allows the same processing infrastructure to serve both performance-critical kernel operations and flexible user-space applications.
Solution Approach 2:
The patent introduces an intermediary mechanism (such as a shared memory interface or standardized data structure) that bridges the kernel driver and user layer. This intermediary allows processing results to be efficiently generated in the kernel while being accessible to user-space applications, thereby maintaining both processing efficiency and user layer adaptability.
