Document Data Thumbnail Transmission for Multi-Page Display Speed

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing communication technologies fail to efficiently transmit document data consisting of multiple pages, as they do not account for the possibility of multiple pages, leading to slow display on devices receiving the data.

Innovation Solution

A communication method that divides document data into predetermined units, generates thumbnail image data elements, and transmits these elements before the main document data, allowing for efficient transmission and display of multi-page documents.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If document data is transmitted as complete multi-page files, then data integrity is maintained, but display speed deteriorates due to large data volume

Engineering Contradiction:

Improvedisplay speedVSAvoiddata volume

Core Design Contradiction:

SpeedVSQuantity of substance

Solution Approach 1:

The patent segments document data into individual page units, allowing the receiving device to receive and display pages sequentially rather than waiting for complete document transmission. This segmentation enables faster initial display while maintaining complete data transmission for full document integrity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent transmits thumbnail images of document pages before transmitting the actual document data. This preliminary action allows the receiving device to prepare display elements in advance, improving perceived display speed while the complete document data is being transmitted in the background.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If thumbnail images are generated and transmitted for each page, then display efficiency improves, but communication load increases

Engineering Contradiction:

Improvedisplay efficiencyVSAvoidcommunication load

Core Design Contradiction:

ProductivityVSQuantity of substance

Solution Approach 1:

The patent creates thumbnail copies of document pages that are much smaller than the original document data. These copies serve as placeholders that enable fast display while the complete document data is transmitted separately, reducing the immediate communication load for display purposes.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent transmits only the necessary portion of document data (individual pages or selected pages) rather than complete multi-page documents. This local quality approach allows the receiving device to display available pages efficiently while minimizing communication load by not transmitting unnecessary data.

Inventive Principle:

Principle #3Local quality

AI summary

A communication method for a personal computer configured to transmit document data constituted by a plurality of pages includes generating a first divided data element and a second divided data element by dividing the document data into predetermined units, generating a first thumbnail image data element in accordance with the generated first divided data element, transmitting the generated first thumbnail image data element, generating a second thumbnail image data element in accordance with the generated second divided data element, transmitting the generated second thumbnail image data element, and after transmitting the first thumbnail image data element, starting transmitting the document data.
