Media Asset Identifier Mapping for Duplicate Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing media systems fail to identify and manage duplicate copies of the same media program, leading to inefficient storage usage as they assign different identifiers to the same media content from various sources, resulting in wasted storage space on devices like digital video recorders (DVRs).
Innovation Solution
A media guidance application is implemented on user equipment to detect duplicate media assets by comparing attributes such as title, description, casting, episode index, and season index, and determines which copy to delete or transfer to another device for storage optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If media assets from different sources are stored using their original media asset identifiers, then each media asset can be uniquely identified and managed, but duplicate copies of the same media program are not detected and storage space is wasted
Solution Approach 1:
The patent introduces a media asset identifier mapping table as an intermediary component that maps multiple source-specific media asset identifiers to a unified media program identifier. This mapping table acts as a mediator between the diverse identification systems of different media sources and the storage system, enabling duplicate detection without losing the unique identification capability of each source. When a media asset is received, the system queries the mapping table to check if the same media program has been stored under different identifiers, thereby preventing duplicate storage while maintaining reliable identification.
2Quantity of substance
If duplicate detection is implemented by comparing media asset identifiers, then storage efficiency can be improved, but duplicate copies from different sources with different identifiers cannot be detected
Solution Approach 1:
The patent transforms the identification parameter from source-specific media asset identifiers to a unified media program identifier that is independent of the source. By changing the parameter of identification from the original identifier (which varies by source) to a normalized media program identifier (which is consistent across sources), the system enables accurate duplicate detection. The media asset identifier mapping table stores the correspondence between original identifiers and unified identifiers, allowing the system to compare media programs based on their essential characteristics rather than source-specific labels.
3Quantity of substance
If a unified media program identifier system is implemented across multiple media sources, then duplicate copies can be accurately detected and storage optimized, but the system complexity increases due to the need for mapping and synchronization
Solution Approach 1:
The patent implements preliminary action by pre-establishing the media asset identifier mapping table that contains the correspondence between various source identifiers and unified media program identifiers. This mapping table is prepared in advance, allowing the system to quickly detect duplicates through simple table lookups rather than complex real-time analysis. When new media assets are received, the system only needs to query the pre-built mapping table to determine if duplicates exist, significantly reducing the computational complexity of duplicate detection while maintaining accurate storage optimization.

AI summary
Systems and methods are disclosed herein for detecting duplicate copies of a media asset and deleting or offloading one of the duplicate copies to different user devices. Specifically, a media guidance application, implemented at user equipment, may be used to record or store media assets from different media sources. The media guidance application may detect a duplicate copy of a previously stored media asset by comparing various attributes of the media asset. After detecting a duplicate copy of a media asset, the media guidance application may determine which of the duplicate copies of the same media asset is to be deleted, or to be transmitted for storage at a different user device.
