Progressive Image Delivery via Position-Based Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of efficiently delivering images over networks is exacerbated by increasing web page sizes and low bandwidth client devices, leading to frustration for end users, as prior optimization methods often result in low quality images.
Innovation Solution
A method and device for progressive image delivery, where an application management computing device identifies and prioritizes images based on their position in web pages, progressively delivering them to client devices, converting low quality images to high quality over multiple passes while minimizing bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If images are optimized for fast delivery, then delivery speed is improved, but image quality deteriorates
Solution Approach 1:
The patent segments the image delivery process into multiple passes: first delivering a low-resolution thumbnail image for immediate display, then progressively delivering additional image data in subsequent passes to reconstruct the full-quality image. This segmentation allows the system to satisfy both the speed requirement (immediate display of thumbnail) and quality requirement (progressive reconstruction of full image).
Solution Approach 2:
The patent performs preliminary action by pre-processing images into progressive JPEG format with multiple quality layers before delivery. The server prepares the image data in advance with embedded quality progression markers, enabling the client to display a usable thumbnail immediately while continuing to receive and reconstruct higher quality versions without interrupting the initial display.
2Quantity of substance
If web page sizes increase, then content completeness is improved, but delivery time increases
Solution Approach 1:
The patent segments the web page content delivery by separating critical content (text, navigation elements) from non-critical content (large images, multimedia). Critical content is delivered first in a minimized format, while non-critical content is delivered progressively in the background, allowing users to access essential information immediately while richer content loads asynchronously.
Solution Approach 2:
The patent applies local quality by delivering different quality levels of the same content based on its importance and position. Critical page elements receive high-priority delivery with full quality, while less important elements receive lower-priority progressive delivery. Image positioning and sizing are optimized locally to minimize overall page load time while maintaining content completeness.
3Manufacturing precision
If images are delivered in high quality, then image quality is improved, but bandwidth consumption increases
Solution Approach 1:
The patent segments image data into multiple quality tiers and delivers them sequentially. The first pass delivers a compressed thumbnail using minimal bandwidth, allowing immediate display. Subsequent passes deliver additional image segments that progressively reconstruct the full-quality image. This segmentation ensures that high image quality is achieved ultimately, but bandwidth is conserved by delivering only essential data first and optional enhancement data later.
Solution Approach 2:
The patent implements periodic action through progressive image delivery where image data is transmitted in periodic bursts rather than as a single large block. The server sends image segments at intervals, allowing the client to display and interact with the content progressively. This periodic transmission pattern optimizes bandwidth utilization by matching delivery rates to network conditions and user needs, reducing peak bandwidth consumption while maintaining quality.

AI summary
A method, non-transitory computer readable medium and an application management computing device that assists with progressive image delivery includes obtaining one or more webpages requested by a client computing device. One or more images are identified in the obtained one or more webpages. The identified one or more images are prioritized based on a position of each of the identified one or more images in the obtained one or more webpages. The prioritized one or more images are progressively delivered to the requesting client computing device. By progressively delivering images over multiple passes, the technology is able to quickly convert the low quality images initially provided to high quality images. Additionally, by converting the low quality images to high quality images over multiple passes, the technology utilizes very less bandwidth thereby providing the requested content to the requesting one of the plurality of client computing devices quickly.
