Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques face difficulties in quickly searching for the storage location of original moving image data or finding a specific scene within it, especially when the data has been converted in terms of resolution, bit rate, and format, and is stored in a different location, making it challenging to synchronize reproduction across various devices.
Innovation Solution
A reproduction control apparatus that includes an obtaining unit to acquire information for the original moving image data, a reproduction unit to generate instructions for reproducing the data, and a communication unit to transmit these instructions via a network to a reproduction control device, allowing for the synchronization of reproduction across different devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If moving image data is converted and stored in mobile terminals for easy access, then accessibility and ease of operation are improved, but the ability to quickly search for original data and specific scenes deteriorates
Solution Approach 1:
The system performs preliminary actions by embedding identification information and scene metadata into the converted moving image data before storage. This allows the reproduction control apparatus to quickly locate and retrieve specific scenes without time-consuming manual searching, thus resolving the contradiction between ease of access and search efficiency
Solution Approach 2:
The invention introduces an intermediary reproduction control apparatus that acts as a mediator between the mobile terminal and the original data storage. This apparatus uses embedded identification information to efficiently locate and retrieve specific scenes, solving the search time problem while maintaining the accessibility benefits of converted data storage
2Adaptability or versatility
If moving image data is stored in different locations (mobile terminal and external storage), then adaptability and storage flexibility are improved, but the complexity of synchronizing reproduction across devices increases
Solution Approach 1:
The reproduction control apparatus is designed with multi-functionality to handle both mobile terminal data and external storage data through a unified control interface. It can identify, retrieve, and synchronize data from different storage locations using embedded identification information, thus managing storage flexibility without proportionally increasing operational complexity
Solution Approach 2:
The system employs feedback mechanisms where the reproduction control apparatus continuously monitors reproduction status across devices and adjusts control instructions accordingly. This feedback loop enables automatic synchronization of reproduced scenes between mobile terminals and external storage, reducing the perceived complexity for users
3Use of energy by moving object
If converted moving image data is used in mobile terminals, then processing capability requirements are reduced, but the quality and resolution of displayed content deteriorates
Solution Approach 1:
The system segments the moving image data processing into two parts: converted data for mobile terminal playback (lower processing requirements) and original high-quality data for external storage (higher quality). The reproduction control apparatus manages both segments, allowing users to access high-quality original data when needed while maintaining energy efficiency on mobile devices
Solution Approach 2:
The invention adds a dimensional aspect by implementing a dual-storage architecture where both converted and original data coexist in different storage dimensions. The reproduction control apparatus can switch between dimensions based on quality requirements, enabling mobile terminals to use energy-efficient converted data while preserving access to high-resolution original data in external storage
