Discontinuous Multimedia Transfer System for Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for mobile multimedia content transfer on mobile computing devices, such as laptops and smartphones, face limitations due to insufficient bandwidth on 3G networks, which hinder the seamless download and viewing of large multimedia files, and DRM policies lead to wasted storage space with expired content.
Innovation Solution
Implementing a discontinuous multimedia content transfer system that allows users to select and purchase content over a 3G connection while deferring the download to a more suitable network, such as WiFi, and automatically managing and removing expired DRM content to optimize storage space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multimedia content is downloaded over 3G network connection, then mobile connectivity and content selection are enabled, but download speed and bandwidth are insufficient for large multimedia files
Solution Approach 1:
The system performs preliminary actions by allowing users to select, preview, and purchase multimedia content over the 3G connection before the actual download occurs. The download is deferred to a later time when a more suitable high-speed connection (WiFi/Ethernet) is available, thus separating the content selection phase from the content transfer phase.
Solution Approach 2:
The system dynamically switches between different network connections based on availability and suitability. It transitions from using 3G for content selection to using WiFi or Ethernet for actual download, adapting the network connection used at each stage to optimize both mobile accessibility and download performance.
2Reliability
If DRM policies are enforced on downloaded content, then content protection is achieved, but storage space is wasted due to expired content that cannot be removed
Solution Approach 1:
The system implements a feedback mechanism that periodically monitors the expiration status of downloaded DRM-protected content. When content expires, the system automatically detects this status and triggers removal of the expired files, thus preventing storage space waste while maintaining content protection for active subscriptions.
Solution Approach 2:
The system automatically discards expired DRM content that is no longer accessible under the subscription model. By removing these expired files, the system recovers storage space that would otherwise be wasted, while maintaining the integrity and protection of currently valid content.
