Compression Dictionary Generation for Adaptive Content Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems face challenges in quickly delivering complex and large digital content over networks due to increased demand, despite improved network throughput, leading to user dissatisfaction if content is not provided promptly.
Innovation Solution
The implementation of shared compression dictionaries between servers and user devices, where dictionaries are selected based on user device, network, and user characteristics, allowing for efficient content compression and decompression by replacing content portions with shorter identifiers, and using snapshot updates and sub-dictionaries to manage dictionary changes and compressions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If digital content is transmitted without compression, then content quality is maintained, but transmission time increases and network efficiency deteriorates
Solution Approach 1:
The patent applies parameter changes by transforming the data representation format through compression. Dictionary-based compression changes the parameters of data encoding by replacing frequent content patterns with shorter identifiers, thereby reducing data size while maintaining content quality for faster transmission.
Solution Approach 2:
The patent uses copying by creating and sharing compression dictionaries between server and client. These dictionaries are copied and stored locally, enabling both parties to use the same compression references, thereby achieving efficient compression without repeatedly transmitting the full dictionary data.
2Productivity
If compression dictionaries are shared between server and user device, then compression efficiency is improved, but system complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-generating and storing compression dictionaries on both server and client devices before actual content transmission. This preliminary setup enables rapid compression during content delivery without requiring complex real-time dictionary creation, thereby improving compression efficiency while managing system complexity.
Solution Approach 2:
The patent uses universality by designing a standardized dictionary format and protocol that can be applied across different content types and transmission scenarios. The same dictionary structure serves multiple functions including compression, decompression, and adaptive updates, reducing overall system complexity through reuse.
3Measurement precision
If dictionary snapshots are updated frequently, then compression accuracy is improved, but network overhead increases
Solution Approach 1:
The patent applies partial action by updating only the necessary portions of compression dictionaries rather than performing full updates. Snapshot mechanisms allow selective synchronization of changed dictionary entries, improving compression accuracy for frequently accessed content while minimizing network overhead by transmitting only incremental changes.

AI summary
A system for dictionary generation that can generate a set of candidate dictionaries based at least in part on subsets of content, where candidate dictionaries of the set of candidate dictionaries are generated based at least in part on a different subset of the content. The system can further use candidate dictionaries of the set of candidate dictionaries to compress the content and can identify one or more dictionary quality metrics for candidate dictionaries of the set of candidate dictionaries based at least in part on the respective compression of the content by candidate dictionaries of the set of candidate dictionaries.
