UGC Cache Verification via Hash and Timestamp
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for processing User Generated Content (UGC) in QT Audio applications lead to performance deterioration of storage servers and clients when users frequently download UGC, causing network bandwidth issues and server overload.
Innovation Solution
A method that involves sending a request for UGC information, determining if the local cache has the latest content using hash values and timestamps, and downloading only if the cache is not up-to-date, thereby reducing network bandwidth usage and enhancing client and server performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users frequently download UGC from the storage server, then users can access the latest content, but the performance of the storage server and client deteriorates
Solution Approach 1:
The system performs preliminary actions by checking UGC information (hash values and timestamps) before initiating full content downloads. This preliminary verification determines whether downloads are necessary, preventing unnecessary network traffic and server load while ensuring content freshness when needed.
Solution Approach 2:
The patent extracts only the essential verification information (hash values and timestamps) from the UGC metadata and transmits this minimal data set between client and server. This extraction approach allows the system to verify content freshness without transferring the actual large UGC files, significantly reducing network bandwidth consumption and server processing load.
2Reliability
If users download UGC regularly to ensure latest content, then content freshness is maintained, but network bandwidth is consumed
Solution Approach 1:
The system extracts and transmits only the minimal necessary information (hash values and timestamps) for verification purposes. This extraction principle allows the client to determine content freshness without downloading the actual UGC files, dramatically reducing network bandwidth consumption while maintaining content freshness guarantees.
Solution Approach 2:
The client performs preliminary verification of UGC information before initiating any data download. By checking hash values and timestamps in advance, the system determines whether downloads are actually needed, preventing wasteful network bandwidth consumption while ensuring content freshness when updates are necessary.

AI summary
A method, apparatus and system for processing User Generated Content are provided. The method comprises sending a request for obtaining UGC information to a network device; receiving UGC information returned by the network device in response to the request for obtaining UGC information; determining whether UGC in a local cache is the latest UGC based on the UGC information; and downloading UGC from the network device if UGC in the local cache is not the latest UGC.
