Reception Apparatus Cache Quota Domain Resource Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies face challenges in effectively sharing resources among multiple services due to limitations in tuner and storage resources in client apparatuses, particularly in caching all receivable broadcast files, which hinders efficient use of cache storage and delivery bandwidth.
Innovation Solution
A reception apparatus and data processing method that utilize resource sharing information to control storage of content resources across multiple services, allowing sharing of resources through a cache quota domain concept, where quota domain identifiers are used to manage and cache files shared among services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all files acquired via broadcasting or communication are cached in a local cache, then file access performance is improved, but storage resource limitations prevent caching all receivable broadcast files
Solution Approach 1:
The patent applies universality by creating a shared cache storage area that serves multiple services simultaneously. Instead of dedicating separate cache storage to each service, the invention establishes a common cache that can be accessed and utilized by multiple services, thereby maximizing the utilization of limited storage resources while maintaining file access performance for all services.
Solution Approach 2:
The patent merges separate cache storage resources into a unified shared cache. By combining individual service caches into a single shared storage area with coordinated access control, the system achieves more efficient use of storage capacity while ensuring that each service can still access its required files with acceptable performance.
2Productivity
If storage resources are released immediately when service is switched, then resource utilization is optimized, but files commonly used in multiple services cannot be shared
Solution Approach 1:
The patent applies preliminary action by pre-establishing a shared cache structure and defining resource sharing rules before services are switched. This allows the system to maintain files commonly used across multiple services in the shared cache, so when service switching occurs, these files remain readily available without requiring immediate re-caching, thus balancing resource utilization with sharing capability.
Solution Approach 2:
The patent implements feedback mechanisms through cache control headers that provide information about file sharing status and cache validity. This feedback allows the system to make intelligent decisions about whether to release or retain cached files when services are switched, ensuring that files needed by multiple services are preserved while optimizing overall resource utilization.
3Productivity
If cache storage is shared among multiple services, then resource efficiency is improved, but control over cache management becomes more complex
Solution Approach 1:
The patent applies segmentation by dividing the shared cache into logical sections or partitions that can be independently managed for different services. This segmentation allows the system to maintain resource efficiency through sharing while reducing control complexity by providing structured organization and service-specific access zones within the shared cache.
Solution Approach 2:
The patent introduces intermediary mechanisms such as cache control headers and coordination protocols that mediate between multiple services accessing the shared cache. These intermediaries simplify the control complexity by providing standardized interfaces and automated conflict resolution, allowing services to access the shared cache without direct complex coordination between them.
