Portable Media Player File Segment Update System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current DirecTV systems require physical movement of the set top box to play recorded content on another television, making it inconvenient and limiting the use of recorded satellite television content on portable media players.
Innovation Solution
A method and system that allows a portable media player to playback files loaded from a storage device, such as a digital video recorder, by coupling the player to the storage device to update and store file segments, enabling seamless transfer and playback of video and audio content while maintaining current information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physical movement of the set top box is required to play recorded content on another television, then content playback is possible, but convenience and ease of operation deteriorates
Solution Approach 1:
The recorded content is divided into multiple segments that can be independently transferred to portable media players. This allows selective transfer of content segments without moving the entire set top box, enabling convenient playback on multiple devices while maintaining system organization.
Solution Approach 2:
A content management system acts as an intermediary between the set top box and portable media players. This mediator handles the complex tasks of content segmentation, transfer, and licensing automatically, improving ease of operation while managing the underlying system complexity.
2Loss of information
If file segments are updated on portable media players, then content currency and information freshness is improved, but data loss risk and reliability concerns worsen
Solution Approach 1:
The system performs preliminary actions by creating backup copies of content segments before updating them on portable media players. This ensures that original content is preserved and can be restored if needed, maintaining data integrity while enabling content updates.
Solution Approach 2:
The content management system implements feedback mechanisms to monitor the update process on portable devices. This includes verifying successful transfers and detecting potential data corruption, allowing the system to respond to update issues and maintain reliability while keeping content current.
