Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data networks, particularly wireless communication networks, face challenges in efficiently delivering high-quality multimedia content to a large number of users due to limited bandwidth and high costs associated with specialized broadcast networks, making it difficult to provide cost-effective and efficient content distribution to multiple users.
Innovation Solution
A transport system that creates and transports multimedia content flows from a content network to an access network, allowing for the adjustment of content flow parameters to accommodate available bandwidth, enabling broadcast distribution to devices on the access network and allowing authorized devices to cache content for later viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If specialized broadcast networks are used to deliver high quality content, then content quality and bandwidth are improved, but cost and geographic limitation worsen
Solution Approach 1:
The patent introduces a content flow adjustment mechanism as an intermediary between the content source and the access network. This mediator translates high-quality content flows into formats suitable for lower-bandwidth access networks, enabling high-quality content delivery without requiring expensive specialized broadcast infrastructure.
Solution Approach 2:
The system dynamically adjusts content flow parameters (such as resolution, bitrate, and quality metrics) to match the capabilities of the access network. By changing these parameters, the system delivers high-quality content adaptation that works within the constraints of standard access networks, avoiding the need for expensive specialized networks.
2Ease of manufacture
If access networks are used to deliver content, then cost is reduced, but bandwidth and content quality deteriorate
Solution Approach 1:
The system adjusts content flow parameters dynamically based on the access network's capabilities. By modifying parameters such as resolution, bitrate, and quality settings, the system maximizes content quality within the constraints of available bandwidth, delivering the best possible quality on standard access networks.
Solution Approach 2:
The content flow adjustment mechanism operates dynamically, adapting to real-time network conditions and user requirements. This dynamic adjustment allows the system to optimize bandwidth utilization and deliver high-quality content on access networks by continuously tuning parameters based on current network state.
3Reliability
If point-to-point communication is used on data channels, then individual user service quality is improved, but efficiency and cost for serving multiple users worsen
Solution Approach 1:
The patent implements a universal content flow adjustment mechanism that serves multiple users simultaneously through a single access network connection. The system can adapt and deliver customized content flows to multiple users based on their individual requirements while sharing the same network infrastructure, achieving both personalized service quality and efficient multi-user distribution.
Solution Approach 2:
The system segments the content delivery process into adjustable flow parameters that can be independently optimized for each user. By dividing the content stream into adjustable components (resolution, bitrate, quality levels), the system can provide personalized service quality to multiple users while efficiently utilizing shared access network bandwidth.
