Solution Overview

Problem

Current wireless multicast networks lack the ability for end users to interactively modify the forward path multi-media content, which is static and immutable, limiting applications that require dynamic feedback and interactivity.

Innovation Solution

The Virtual Aggregation Processor enables dynamic modification of forward path content through real-time aggregation and processing of reverse path feedback from end users, creating a closed loop system that continuously updates the content delivered to end user devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If wireless multicast networks deliver static content via forward path, then delivery efficiency and capacity are improved, but interactivity and dynamic modification capability deteriorate

Engineering Contradiction:

Improvedelivery efficiencyVSAvoidinteractivity

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent implements a feedback mechanism where end user devices send reverse path feedback to the network, which is then aggregated and used to dynamically modify forward path content. This closed-loop feedback system enables interactive content modification while preserving efficient multicast delivery, directly resolving the contradiction between delivery efficiency and interactivity.

Inventive Principle:

Principle #23Feedback

2Productivity

If content is delivered as immutable replica via multicast, then network capacity efficiency is improved, but content distinction and regional targeting capability deteriorate

Engineering Contradiction:

Improvenetwork capacity efficiencyVSAvoidcontent distinction

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent segments the content delivery system into modular components: content sources, virtual aggregation processors, and end user devices. This segmentation allows different regions or user groups to receive customized content modifications while sharing the same base multicast stream, enabling both high network efficiency and content distinction simultaneously.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system transitions from static immutable content to dynamic modifiable content through real-time feedback processing. The virtual aggregation processor dynamically adjusts content based on aggregated user feedback, enabling regional and demographic targeting while maintaining efficient multicast delivery of the base content stream.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If feedback aggregation is implemented in real-time, then content relevance and user engagement are improved, but processing complexity and system overhead increase

Engineering Contradiction:

Improvecontent relevanceVSAvoidprocessing complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces virtual aggregation processors as intermediary elements between end user devices and content sources. These intermediaries aggregate feedback from multiple users, process modifications centrally, and distribute updated content efficiently. This intermediary layer reduces individual device complexity while enabling sophisticated real-time content personalization.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

The Virtual Aggregation Processor enables end user devices to share a common wireless forward path of a multicast communication architecture in which the forward path delivered content is dynamically changed or modified based on a real-time, near-real-time, or delay-time basis via aggregated reverse path feedback from at least one of a plurality of end user devices. The Virtual Aggregation Processor periodically or continuously aggregates the feedback input received via the reverse path (having wired and/or wireless connectivity), modifies the forward path multi-media content, and delivers this dynamically modified multi-media content to the then connected population of end user devices via a wireless forward path multicast in a repetitive closed loop fashion.
