Onboard Media Server Storage Control Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing volume of media content in on-board entertainment systems, driven by higher resolutions and quality standards, leads to significant storage requirements and inefficient bandwidth usage, as existing systems lack effective management of content retention and replication.
Innovation Solution
A media server with a storage control module that collects access data to calculate a retention parameter for each media item, automatically deciding on retention or deletion, and dynamically adjusts replication levels based on usage, optimizing storage space and bandwidth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If media content is stored with high replication levels to ensure availability and compensate for hardware failures, then reliability is improved, but storage space requirements increase significantly
Solution Approach 1:
The patent implements dynamic replication level adjustment based on content popularity metrics. The storage control module continuously monitors access patterns and adjusts replication levels accordingly - high-popularity content maintains high replication for reliability, while low-popularity content reduces replication to conserve storage space. This dynamic adaptation resolves the contradiction between ensuring content availability and minimizing storage requirements.
Solution Approach 2:
The system changes the replication parameter based on content characteristics and usage patterns. By introducing a popularity metric and adjusting replication levels as a variable parameter rather than using fixed high replication for all content, the system optimizes the balance between reliability and storage efficiency. Content is categorized and assigned different replication levels based on measured popularity.
2Manufacturing precision
If media content is manually added and managed, then storage control precision is improved, but device complexity and operational burden increase
Solution Approach 1:
The storage control module operates autonomously by collecting access data, calculating popularity metrics, and automatically adjusting replication levels without manual intervention. The system self-manages storage optimization by monitoring its own usage patterns and making adaptive decisions, thereby achieving precise storage control while reducing operational complexity and human burden.
Solution Approach 2:
The system implements a closed-loop feedback mechanism where access data from user terminals is collected, processed into popularity metrics, and used to automatically adjust content replication. This feedback loop enables precise, data-driven storage management that adapts to changing usage patterns without requiring manual reconfiguration.
3Reliability
If all media content is stored at maximum replication levels, then content availability is improved, but bandwidth consumption for content updates and synchronization increases
Solution Approach 1:
The patent dynamically adjusts replication levels based on content popularity rather than using uniform maximum replication. This allows the system to maintain high availability for popular content while reducing bandwidth consumption for less popular content during updates and synchronization operations, thereby resolving the contradiction between reliability and energy/bandwidth efficiency.

AI summary
A media server for an on-board entertainment system comprising terminals, the server comprising:a memory for storing media content;a distribution module configured to distribute stored media content to terminals;a controller for controlling the storage of media content in the storage module;wherein the controller is configured to collect the numbers of accesses via the terminals to the media content, to calculate the value of a retention parameter relating to each item of media content as a function of said number of accesses, and to automatically trigger the continued retention of said media content in the memory or its deletion as a function of at least said calculated value.
