Document Content Reconstruction for Layout Fidelity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The education publishing industry faces challenges in efficiently ingesting, publishing, distributing, and managing electronic content due to a lack of digital textbook standardization, content protection, and interoperability, which hinders the growth of online delivery networks.
Innovation Solution
A method and system for document content reconstruction in a digital content delivery platform that ingests unstructured documents, extracts images and metadata, converts them into structured HTML5 format, preserving layout fidelity, and allows dynamic content rendering across multiple platforms, enabling flexible distribution and user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If unstructured document formats are used for digital textbooks, then ease of manufacture and distribution is improved, but manufacturing precision and layout fidelity deteriorate
Solution Approach 1:
The patent introduces an intermediary processing system that converts unstructured document formats into structured HTML5 format with embedded CSS styles. This intermediary step preserves the original unstructured format's ease of distribution while achieving the desired layout fidelity through systematic conversion processes that maintain positional information and styling.
Solution Approach 2:
The patent transforms documents by changing their structural parameters from unstructured formats to structured HTML5 format. This parameter change enables both ease of distribution (through web-compatible formats) and layout fidelity (through structured markup with embedded styling information).
2Ease of operation
If complete document delivery is used, then user experience is improved, but content protection and piracy risks worsen
Solution Approach 1:
The patent segments the complete document into individual pages or sections that can be delivered and accessed separately. This segmentation maintains good user experience by allowing progressive loading and offline access to individual pages while reducing piracy risks by limiting the amount of content exposed at any one time and enabling more granular rights management.
3Adaptability or versatility
If multiple device platforms are supported, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent uses HTML5 as a universal format that can be rendered across multiple device platforms (desktop browsers, mobile devices, tablets, e-readers) without requiring platform-specific versions. This universal approach improves adaptability while minimizing system complexity by eliminating the need for separate conversion pipelines for each device type.
4Device complexity
If static content delivery is used, then simplicity is improved, but connected services and interactivity deteriorate
Solution Approach 1:
The patent transforms static document delivery into a dynamic system where HTML5 pages can be selectively delivered, updated, and interacted with. The structured format enables dynamic content updates without requiring complete document redelivery, and the web-based approach enables integration with connected services while maintaining relative system simplicity through standardized web technologies.

AI summary
A method, a storage medium and a system for document content reconstruction are provided in a digital content delivery and online education services platform to enable delivery of textbooks and other copyrighted material to multi-platform web browser applications. The method comprises ingesting a document page in an unstructured document format. The method further comprises extracting one or more images and metadata associated with the images and text and fonts associated with the texts from the document page. In addition, the method comprises coalescing text into paragraphs and creating a structured document page in a markup language format using the extracted images, text and fonts rendered with layout fidelity to the original ingested document page.
