Metadata Decoding Using Version Checks to Skip Redundant Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for encoding and decoding metadata lack efficiency in determining whether metadata has been updated or remains unchanged, leading to unnecessary decoding and increased computational complexity.
Innovation Solution
The solution involves using unique location information or a cycle of inserting metadata packets into a transmission stream to determine if metadata has been updated, allowing for skipping of redundant decoding processes by comparing location information or cycle changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If metadata is decoded in every transmission cycle, then data completeness is ensured, but computational overhead increases due to redundant decoding
Solution Approach 1:
The patent applies preliminary action by inserting version information into metadata packets before transmission. This allows the receiver to pre-check whether metadata has changed by comparing version information, avoiding the need to fully decode metadata in every transmission cycle. The version information acts as a preliminary indicator that prevents redundant decoding operations while ensuring data completeness when changes are detected.
2Speed
If metadata decoding is performed frequently, then updated information is captured promptly, but processing time and energy consumption increase
Solution Approach 1:
The patent extracts version information from metadata packets as a separate, independent element that can be checked without full metadata decoding. This extraction allows the system to quickly detect metadata updates by comparing version information alone, capturing update information promptly while avoiding the time-consuming process of fully decoding metadata in every cycle. The version information serves as a lightweight proxy for update detection.
3Reliability
If all metadata packets are processed in every transmission cycle, then no data is missed, but bandwidth efficiency decreases due to redundant data transmission
Solution Approach 1:
The patent applies partial action by processing only the version information portion of metadata packets rather than the entire metadata content in every transmission cycle. The receiver performs partial decoding to extract and compare version information, and only fully processes metadata packets when version changes are detected. This approach ensures data completeness by maintaining version tracking while significantly improving bandwidth efficiency by avoiding redundant full metadata processing.
Data Source
AI summary
Provided are a meta data encoding/decoding method and apparatus. The meta data decoding method includes decoding a media signal containing a media object, and decoding meta data corresponding to the media object. During the decoding of the meta data signal, decoding of the meta data is skipped when the meta data that is to be decoded is identical to already decoded meta data.
