Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If video frames are stored using traditional logical block addressing, then storage structure is simple, but video frame searching and processing efficiency deteriorates
Solution Approach 1:
The patent segments video storage by creating separate metadata tables (first metadata table for video frame metadata, second metadata table for video stream metadata) independent from the actual video data storage. This segmentation allows efficient metadata-based searching without complicating the underlying video data storage structure, resolving the contradiction by enabling advanced searching capabilities while maintaining simple storage architecture.
Solution Approach 2:
The patent introduces metadata as an intermediary layer between the storage system and video frames. The metadata contains indexing information that enables efficient searching and processing of video frames without requiring complex modifications to the storage structure itself. This intermediary approach allows the system to achieve high searching efficiency while maintaining storage structure simplicity.
2Adaptability or versatility
If variable-length video frames are stored, then storage flexibility improves, but storage management efficiency deteriorates
Solution Approach 1:
The patent applies preliminary action by generating and storing metadata for each video frame before the actual storage operation completes. The metadata includes pre-calculated indexing information about video frame characteristics, which enables efficient subsequent management and retrieval operations. This preliminary metadata preparation allows the system to handle variable-length frames efficiently without compromising storage management performance.
Solution Approach 2:
The patent changes the parameter representation by storing metadata parameters (frame length, timestamp, sequence number, etc.) separately from the video frame data itself. This parameter separation allows the system to efficiently manage variable-length frames by working with compact metadata parameters rather than the full variable-length frame data, thus maintaining both storage flexibility and management efficiency.
3Measurement precision
If metadata extraction and processing is performed, then video frame retrieval accuracy improves, but processing time increases
Solution Approach 1:
The patent performs metadata extraction as a preliminary action during the video frame storage process itself, rather than during retrieval. By extracting and storing metadata (including indexing information about frame characteristics) at write time, the system prepares retrieval-ready data structures in advance. This eliminates the need for time-consuming metadata extraction during read operations, thus achieving high retrieval accuracy without sacrificing processing time.
Solution Approach 2:
The patent applies beforehand cushioning by pre-processing and storing comprehensive metadata information that cushions against future retrieval delays. The metadata includes pre-analyzed characteristics of video frames that enable rapid accurate retrieval without requiring re-processing during read operations. This prior preparation ensures both high retrieval accuracy and efficient processing timing.
