Web Browser Content Rendering Latency Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network latency causes web browser applications to become unresponsive when rendering large content, as they need to receive the entire content before rendering, leading to poor user experience.
Innovation Solution
The technique involves analyzing original content to identify resource-intensive items, extracting them, and replacing them with extraction markers in the modified content, allowing the client application to start rendering sooner and retrieve the extracted items asynchronously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the entire content is transmitted before rendering, then the content rendering completeness is ensured, but the initial render time increases and user experience deteriorates
Solution Approach 1:
The content is segmented into two categories: renderable content (text, placeholder information) and non-renderable content (large images, videos, audio files). The renderable content is transmitted and rendered immediately, while non-renderable content is loaded asynchronously in the background. This segmentation allows the system to achieve partial rendering quickly while ensuring complete content delivery.
Solution Approach 2:
The system performs preliminary actions by transmitting and rendering the available content portions before the entire content is ready. The web browser application renders text and placeholder information immediately upon receipt, providing visible content to users before all resources (images, videos) are fully loaded. This preliminary rendering action reduces perceived wait time while maintaining rendering completeness through subsequent asynchronous loading.
2Productivity
If resource-intensive content is included in the main content stream, then content completeness is maintained, but network transmission time increases
Solution Approach 1:
Resource-intensive content elements (large images, videos, audio files) are extracted from the main content stream and loaded separately through asynchronous requests. The main content stream contains only essential renderable content and placeholder information, significantly reducing its size and transmission time. The extracted resources are then loaded in the background and integrated into the rendered content, maintaining completeness while improving transmission speed.
3Ease of operation
If the web browser application waits for complete content reception, then rendering accuracy is ensured, but application responsiveness decreases
Solution Approach 1:
The web browser application serves itself by rendering available content portions immediately without waiting for complete content reception. The application uses placeholder information and partial content data to create visible representations, providing responsive user experience. The application continuously updates the rendering as additional content arrives asynchronously, maintaining accuracy while ensuring responsiveness throughout the content loading process.

AI summary
Content rendering techniques are disclosed that reduce latency in rendering of content by extracting resource intensive content from the content. An example method may include identifying items of resource intensive content included in an item of original content, and extracting the items of resource intensive content from the item of original content. The extracted items of resource intensive content are replaced with corresponding extraction markers in the item of original content to create an item of modified content. At the time of rendering the item of modified content, the extracted items of resource intensive content may be retrieved and appropriately inserted into the item of modified content to recreate the item of original content.
