Content Preloading for Offline Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in accessing high-bit-rate content, especially in situations where broadband network access is limited or unavailable, such as during travel, due to insufficient connectivity in mobile communications, which restricts the use of content like films or large data volume services.
Innovation Solution
A system and method that preloads high-bit-rate content into a memory accessible to the terminal device or a central memory during times of favorable connectivity, allowing for later retrieval when connectivity is reduced or interrupted, using wireless high-bit-rate transmission technology and a network-based storage approach that supports digital rights management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If preloading content during favorable connectivity is implemented, then content availability is improved, but device memory requirements increase
Solution Approach 1:
The system divides content storage across multiple locations: local device memory for frequently accessed content, and remote server storage for archival content. This segmentation allows content to be distributed rather than concentrated in one location, reducing peak memory requirements while maintaining availability.
Solution Approach 2:
The patent implements a nested storage architecture where local device memory is embedded within a broader cloud-based storage system. Content can be stored locally when needed and automatically archived to remote servers when not in use, creating a nested structure that provides both local speed and remote capacity.
2Speed
If high-bit-rate transmission is used to transfer large data volumes, then transmission speed is improved, but network infrastructure complexity increases
Solution Approach 1:
The system performs preliminary content preparation and segmentation on remote servers before transmission. Content is pre-processed, formatted, and divided into manageable chunks, reducing the complexity of real-time transmission operations and enabling more efficient high-bit-rate transfers when connectivity is available.
Solution Approach 2:
The patent introduces content servers as intermediary components between users and content sources. These servers handle the complex tasks of content aggregation, formatting, and management, simplifying the overall network architecture while enabling high-bit-rate transmission through optimized data pipelines.
3Speed
If content is cached locally for offline access, then access speed is improved, but storage capacity requirements increase
Solution Approach 1:
The system implements dynamic content caching where the amount of locally stored content automatically adjusts based on usage patterns, device storage availability, and predicted user needs. Frequently accessed content is cached locally for fast access, while less frequently used content is stored remotely, creating a dynamic balance between local speed and remote capacity.
Solution Approach 2:
The patent changes the state of content storage from static to variable by implementing intelligent caching algorithms that monitor access frequency, device resources, and network conditions. These parameter changes enable the system to optimize the balance between local caching and remote storage based on real-time conditions.
