Web Page Compatibility Indicator for Bandwidth Savings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices often lack support for various types of content on web pages, leading to wasted bandwidth and time as users must download entire web pages to determine compatibility, especially with devices like iOS not supporting Flash content or Android browsers not supporting SVG formats.
Innovation Solution
A computer-implemented method to indicate compatibility by obtaining a link to a web page, determining the device's capabilities, and the web page's requirements, and displaying a compatibility result, such as a percentage, next to the link, allowing users to decide whether to visit the page based on support levels for rendering and functional compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a user accesses a web page to determine content support on a device, then compatibility information is obtained, but bandwidth is wasted and time is consumed downloading entire web pages
Solution Approach 1:
The patent extracts only the essential compatibility information (capability requirements) from web pages without requiring users to download entire web pages. A compatibility module analyzes device capabilities against required capabilities and presents only the relevant compatibility assessment, eliminating bandwidth waste while maintaining accurate compatibility measurement.
Solution Approach 2:
The patent performs compatibility assessment in advance by comparing device capabilities with web page requirements before actual web page access. The system pre-determines compatibility results and presents them to users, allowing informed decisions about whether to access the web page, thus avoiding unnecessary bandwidth consumption and time expenditure.
2Reliability
If the entire web page is downloaded to check compatibility, then complete compatibility information is obtained, but time is wasted
Solution Approach 1:
The system extracts only the necessary capability requirements from web pages (such as Flash, SVG, JavaScript support) without downloading the entire web page content. This selective extraction maintains reliable compatibility determination while dramatically reducing the time required for assessment.
Solution Approach 2:
The compatibility module performs capability comparison in advance by matching device capabilities against required capabilities before web page access. This preliminary assessment provides reliable compatibility information instantaneously, eliminating the time-consuming process of downloading entire web pages for analysis.
3Measurement precision
If compatibility checking is performed by accessing web pages, then accurate support information is obtained, but bandwidth is consumed
Solution Approach 1:
The patent extracts only the essential capability requirements (Flash, SVG, JavaScript, etc.) from web pages without requiring full web page downloads. This selective extraction maintains accurate compatibility measurement while minimizing bandwidth consumption to only the essential metadata needed for assessment.
Solution Approach 2:
The system performs capability matching in advance by comparing device capabilities with required capabilities before actual web page access. This preliminary compatibility determination achieves accurate measurement without consuming bandwidth for downloading entire web pages, as the assessment is based on extracted capability requirements alone.
