Communication Content Transfer via Largest-File Compression Preview
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in quickly delivering content without exceeding the data limit at the transfer destination due to time-consuming file size calculations and compression processing, leading to potential file size mismatches and incomplete transfers.
Innovation Solution
A communication apparatus that extracts and compresses the content with the largest data amount first, allowing users to adjust settings based on actual file size calculations before transfer, ensuring the data limit is not exceeded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If file size calculation and compression processing are performed on all contents before transfer, then the accuracy of total file size estimation is improved, but the time required for content delivery increases
Solution Approach 1:
The patent extracts only the necessary information (file size metadata) from contents rather than processing all contents. The extraction unit obtains file size information without performing full compression processing, enabling quick estimation while avoiding time-consuming operations on every file.
Solution Approach 2:
The patent performs preliminary acquisition of file size information before compression processing. By obtaining file size metadata in advance and using it for estimation, the system avoids waiting for complete compression of all contents, thus reducing delivery time while maintaining accuracy.
2Loss of time
If random content is used as reference for file size estimation, then the processing time is reduced, but the accuracy of total data amount estimation deteriorates
Solution Approach 1:
The patent changes the reference parameter from random content selection to selecting content with the largest file size. This parameter change ensures that the reference value is always sufficient to cover the actual total data amount, preventing underestimation while maintaining quick processing.
Solution Approach 2:
The patent applies preliminary anti-action by selecting the largest file as reference, which preemptively prevents the total data amount from exceeding the estimated value. This approach counteracts the potential problem of underestimation that would occur with random selection, ensuring the upper limit is not exceeded.
3Quantity of substance
If compression processing settings are adjusted to reduce file size, then the data amount within transfer limit is improved, but the time required for compression processing increases
Solution Approach 1:
The patent applies partial action by performing compression processing only on the reference content (the largest file) rather than all contents. This partial processing provides sufficient information for accurate estimation and safe transfer decision-making, avoiding the time cost of compressing every file while ensuring the data amount limit will not be exceeded.
Data Source
AI summary
A communication apparatus that is able to communicate with an external apparatus, includes a transfer unit that transfers contents to a transfer destination, an extraction unit that extracts a predetermined content having a largest data amount from the contents to be transferred, and a presentation unit that presents, before transferring the contents, a data amount after compression processing of the predetermined content.
