Mobile Browser Plug-in UCS Document Streaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for viewing documents on mobile devices via URLs from web browsers are inefficient, requiring download and launch of original authoring applications, which consume resources and do not effectively handle document formatting and storage on mobile devices.
Innovation Solution
A mobile browser plug-in, 'DocView', in conjunction with a Mobile Data Service (MDS) and Attachment Server, converts documents into Universal Content Stream (UCS) format for efficient wireless delivery and display, allowing partial document loading and viewing without storage persistence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the original authoring application is launched to display the downloaded document, then the document can be viewed with full functionality, but device resources are consumed and storage space is required
Solution Approach 1:
A browser plug-in serves as an intermediary between the web browser and the document viewing function. The plug-in intercepts document URLs, converts them to UCS format, and displays them within the browser interface itself, eliminating the need to launch separate authoring applications and reducing device resource consumption while maintaining document viewing capability
Solution Approach 2:
The patent creates a simplified copy of the document viewing function that operates within the browser environment. Instead of requiring the original authoring application, the plug-in generates a UCS-based rendering that replicates the essential viewing functionality without the resource overhead of the full application
2Duration of action of stationary object
If the document is downloaded and stored on the mobile device, then the document can be viewed later, but storage space is consumed
Solution Approach 1:
The document viewing process is segmented into streaming portions rather than requiring complete download and storage. The UCS format enables incremental loading of document content as needed, allowing users to access portions of documents without storing the entire document on the device, thus reducing storage space requirements while maintaining document availability
Solution Approach 2:
The patent changes the data format parameter from native authoring application formats to UCS (Universal Content Stream) format. This parameter transformation enables documents to be transmitted and displayed without requiring permanent storage on the mobile device, as the UCS format can be generated on-demand from the original document source
3Reliability
If the complete document is downloaded, then the document can be viewed, but delivery time and bandwidth are consumed
Solution Approach 1:
Instead of downloading the complete document, the patent implements partial loading of document content. The UCS format enables the system to load only the necessary portions of the document as the user navigates or scrolls, significantly reducing delivery time and bandwidth consumption while maintaining the ability to view the complete document as needed
Data Source
AI summary
A method is set forth of displaying a document identified by a URL on a mobile browser, comprising registering an attachment viewer plug-in to the mobile browser for a predetermined data stream content type, registering a mobile data service transcoder for predetermined document types, sending a request for the document of one of the predetermined document types from the mobile browser to the mobile service transcoder, retrieving and converting the document to the predetermined data stream content type, and forwarding the converted document from the mobile data service transcoder to the mobile browser for display via the attachment viewer plug-in.
