Two-Way Media Synchronization via Bidirectional Data Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional personal computers are inefficient in retrieving media content from portable consumer electronic media devices for storage on the desktop, lacking the ability to seamlessly integrate updates and modifications made on portable devices into the desktop environment.
Innovation Solution
A system and method for enabling two-way synchronization between a client computer and a portable media device, allowing users to identify and retrieve media data that has been modified or added since the last synchronization, and selectively transfer this data for storage on the client computer, using a media player application that includes components for identification, retrieval, and user interface management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional personal computers are used to transfer media content from portable devices, then media content can be transferred, but the retrieval efficiency is poor and seamless integration of updates is not achieved
Solution Approach 1:
The patent inverts the conventional one-way transfer model by implementing two-way synchronization. The system not only pushes media content from desktop to portable devices but also automatically retrieves updates and modifications from portable devices back to the desktop, transforming a unidirectional process into a bidirectional synchronization system that resolves the efficiency and integration issues
Solution Approach 2:
The system implements feedback mechanisms where the desktop computer receives information about media content modifications made on portable devices. Through transaction reports and change detection, the system automatically identifies and retrieves updated content, creating a closed-loop feedback system that enables seamless integration without manual intervention
2Adaptability or versatility
If portable media devices allow users to modify or update media content, then media experience is improved, but the desktop cannot efficiently retrieve these updates
Solution Approach 1:
The system performs preliminary actions by establishing synchronization protocols and transaction reporting mechanisms before media content modifications occur. When a portable device connects, the system proactively queries for changes using transaction IDs and timestamps, retrieving updates before the user even becomes aware of them, thus maintaining desktop content currency automatically
Solution Approach 2:
The synchronization system operates autonomously to detect and retrieve media content updates. The desktop computer automatically identifies modified files through transaction reports, downloads updates without user intervention, and integrates them into the media library, making the update retrieval process self-service and eliminating the need for manual synchronization operations
Data Source
AI summary
A system and method for retrieving media data from a portable media device for storage on a client computer during synchronization between the portable media device and the client computer. A media player application (MPA) identifies media data on the portable media device that has been modified since a last synchronization process, and automatically or selectively retrieves the modified and/or unmodified media data from the portable media device for storage on the client computer.
