FTP Session Coordination for Ordered Image-Audio Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face issues where audio files attached to image files are transferred to external apparatuses, such as FTP servers, before the corresponding image files, disrupting the intended workflow and potentially causing editing delays.
Innovation Solution
A communication apparatus is equipped with a control unit that manages multiple data transfer paths to ensure audio files are transferred after the associated image files by rearranging files with the same name in a specific order and utilizing available FTP sessions for simultaneous transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If multiple FTP sessions are established to transfer multiple image files simultaneously to improve throughput, then transfer speed is improved, but audio files may arrive before their corresponding image files
Solution Approach 1:
The control unit performs preliminary sorting of files to be transferred, arranging image files and their corresponding audio files in a predetermined sequence where image files are listed before audio files. This preliminary arrangement ensures that even when multiple FTP sessions operate simultaneously, the audio files will be transferred after their corresponding image files, resolving the contradiction between transfer speed and transfer order reliability.
2Productivity
If audio files are transferred separately to enable simultaneous transfer with image files, then transfer throughput is improved, but the audio files may disrupt the workflow by arriving before image files
Solution Approach 1:
The control unit creates a predetermined transfer list that sequentially lists image files and their associated audio files before initiating transfer. This preliminary organization allows the system to maintain workflow continuity by ensuring image files are transferred first, followed by their audio files, even when utilizing multiple parallel FTP sessions for high throughput.
Solution Approach 2:
The control unit manages multiple FTP sessions and monitors their progress, using feedback information to coordinate the transfer of audio files only after their corresponding image files have been successfully transferred. This feedback mechanism ensures workflow continuity while maintaining high transfer throughput through parallel processing.

AI summary
A communication apparatus includes a connection unit that connects with an external apparatus so as to be capable of communication, and a control unit that establishes a plurality of data transfer paths with the external apparatus with which a connection has been established by the connection unit, selects a data transfer path on which transfer is performed, for each image file from among the plurality of data transfer paths, and transfers the image file. The control unit selects a data transfer path on which transfer of a file is possible from among the plurality of data transfer paths, and in a case of transferring an audio file attached to the image file, selects a data transfer path on which transfer of the image file to which the audio file is attached has been performed.
