Progressive Multimedia Delivery via Segmented Encoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The fast and efficient delivery of multimedia content over networks is hindered by increasing web page sizes and low bandwidth connections, leading to user frustration, as existing methods either compress content to unacceptable quality or require complete object download before display.
Innovation Solution
A progressive content delivery system that re-encodes multimedia content into a progressive format, allowing initial low-quality rendering and incremental quality improvement, enabling concurrent delivery and on-demand retrieval of multimedia objects like images, text, and video.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If multimedia content is compressed to reduce bandwidth consumption, then delivery speed is improved, but content quality deteriorates to unacceptable levels
Solution Approach 1:
The patent segments multimedia content into multiple quality levels or resolutions. Instead of delivering a single compressed version, the system divides content into hierarchical layers (e.g., base layer and enhancement layers) that can be delivered progressively, allowing users to receive and view content at lower quality initially while maintaining the option to receive higher quality versions later.
Solution Approach 2:
The patent applies preliminary action by delivering a preliminary version or preview of multimedia content before the complete high-quality version. Users receive and can view content at reduced quality or resolution first, providing immediate satisfaction, while the full quality content continues to be delivered in the background for later rendering.
2Manufacturing precision
If complete multimedia objects are downloaded before display, then content quality is maintained, but user waiting time increases
Solution Approach 1:
The patent segments the delivery process into multiple phases: an initial phase delivering essential or preview content for immediate display, followed by subsequent phases delivering additional content or quality enhancements. This allows the web page to be displayed progressively rather than requiring complete content download beforehand.
Solution Approach 2:
The system performs preliminary delivery of content that can be displayed immediately (such as thumbnails, low-resolution versions, or essential text) while the complete high-quality multimedia objects continue to download in the background. This preliminary action eliminates user waiting time for initial display while preserving final content quality.
3Loss of energy
If high compression ratios are applied to multimedia objects, then bandwidth consumption is reduced, but image quality becomes unacceptable
Solution Approach 1:
The patent applies local quality by delivering different quality levels to different regions or portions of multimedia content based on user needs and network conditions. Critical or visually important regions may receive higher quality treatment while less important areas use lower compression, optimizing the trade-off between bandwidth consumption and perceived image quality.
Solution Approach 2:
The system dynamically adjusts compression ratios and quality levels based on real-time network conditions, user preferences, and content importance. Rather than applying a fixed high compression ratio, the system can adaptively modify delivery parameters to maintain acceptable quality while minimizing bandwidth usage.
4Quantity of substance
If web page size increases to include more multimedia content, then content completeness is improved, but delivery speed decreases
Solution Approach 1:
The patent segments web page content into prioritized groups or layers, delivering essential content first and optional or enhancement content subsequently. This allows the web page to be displayed with core content immediately while additional multimedia elements continue to load, maintaining content completeness without sacrificing initial delivery speed.
Solution Approach 2:
The system delivers a partial version of the complete web page content that is sufficient for initial display and user interaction. Not all multimedia objects need to be fully delivered before the page becomes functional, allowing users to access core content quickly while optional enhancements load in the background.

AI summary
The present disclosure relates to methods and systems for progressively delivering multimedia content over a network. According to one aspect, a system for delivering multimedia content through a network includes a server side sub-system and a client side sub-system. The server side sub- system is configured to: concurrently send a first predetermined portion of each of the plurality of objects through the network, wherein the first predetermined portion is less than a complete object for at least one of the plurality of objects; and after sending the first predetermined portion of each of the plurality of objects, successively send subsequent predetermined portions of each of the plurality of objects until all portions of the plurality of objects have been sent. The client side sub-system is configured to: receive the first predetermined portion of each of the plurality of objects through the network; and after receiving the first predetermined portion of each of the plurality of objects, successively receive subsequent predetermined portions of each of the plurality of objects until all portions of each of the plurality of objects have been received.
