Data Transfer System Format Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transfer systems require cumbersome procedures for users to convert file formats when the format of the content differs from the format supported by the playback apparatus, leading to increased costs due to the need for multiple codecs and resource utilization.
Innovation Solution
A data transfer system with a format acquisition unit and a conversion unit that automatically converts data formats in parallel using multiple processors, allowing seamless transfer to devices with different supported formats without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a reproducing apparatus or output apparatus supports many types of file formats, then the ability to process various content formats is improved, but the number of codecs and resources required increases, leading to higher manufacturing costs
Solution Approach 1:
The patent introduces a file format conversion apparatus as an intermediary device between the content source and the output apparatus. This converter handles the file format translation, allowing the output apparatus to maintain a limited, fixed set of codecs while still being able to process diverse content formats through the conversion service.
Solution Approach 2:
The conversion apparatus provides universal functionality by accepting multiple input formats and converting them to a standardized set of output formats. This multi-functional converter serves various output devices with different format requirements through a single unified system rather than requiring each device to include all possible codecs.
2Adaptability or versatility
If a user uses a file format converting program on a personal computer, then the file format conversion capability is improved, but the operational complexity and time required increase
Solution Approach 1:
The conversion apparatus operates autonomously without requiring user intervention. It automatically detects the input file format, determines the appropriate output format based on the connected output apparatus, performs the conversion, and transfers the data without the user needing to manually select formats or configure settings.
Solution Approach 2:
The system performs file format conversion in advance before the data reaches the output apparatus. By preparing the converted data beforehand, the system eliminates the need for users to manually handle format conversion steps during the playback or processing operation.
3Adaptability or versatility
If multiple codecs are installed on an apparatus, then the support for various file formats is improved, but the manufacturing cost and resource requirements increase
Solution Approach 1:
The conversion apparatus acts as an intermediary that handles format translation externally, allowing the output apparatus to use a minimal, fixed set of codecs. This external conversion service reduces the resource burden on the output device while maintaining broad format support capability.
Data Source
AI summary
In a data transfer system, when transferring data which has been transferred to a storage in a PC, to a mobile terminal connected to the PC, the PC acquires the file format of the data and the file format which can be processed by the mobile terminal and determines whether the conversion of the file format is necessary. When the conversion of the file format is necessary, the PC issues a request for a conversion to a format converter. The format converter acquires data from the PC and transfers the data back to the PC while performing conversion. The PC transfers the converted data to the mobile terminal.
