Solution Overview

Problem

Existing AVB networks face inefficiencies in managing large numbers of audio and video streams, particularly passive ones without active listeners, leading to high processing burdens and scalability challenges due to individual stream monitoring and resource allocation.

Innovation Solution

Distinguish between active and passive streams, aggregating passive streams into a single entity for management, reducing complexity and processing demands by treating them collectively, and optimizing resource allocation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If individual monitoring and resource allocation is performed for each stream, then stream management accuracy is improved, but processing burden and device complexity increase significantly

Engineering Contradiction:
Improvestream management accuracyVSAvoidprocessing burden
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent merges multiple passive streams into a single aggregated stream entity for monitoring and resource allocation purposes. This combining approach maintains accurate tracking of individual active streams while reducing the overall complexity by treating passive streams collectively, thereby resolving the contradiction between management accuracy and processing burden.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent segments stream management into two distinct categories: active streams that require individual monitoring and resource allocation, and passive streams that are monitored collectively as a group. This segmentation allows precise management of active streams while simplifying passive stream handling, thus balancing accuracy requirements with processing capacity.

Inventive Principle:
Principle #1Segmentation

2Manufacturing precision

If all streams are managed individually, then resource allocation accuracy is improved, but network scalability deteriorates

Engineering Contradiction:
Improveresource allocation accuracyVSAvoidnetwork scalability
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The patent combines passive streams into an aggregated entity that shares common resource allocation parameters. This merging enables the network to handle a large number of streams without proportionally increasing management complexity, thereby improving scalability while maintaining adequate resource allocation accuracy through the aggregated management approach.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent divides stream management into active and passive categories, applying different management granularities to each segment. Active streams receive individualized resource allocation for precision, while passive streams are managed in groups for scalability. This segmented approach allows the network to scale efficiently while preserving resource allocation accuracy where needed.

Inventive Principle:
Principle #1Segmentation

3Reliability

If comprehensive stream monitoring is implemented, then transmission quality is improved, but processing time and energy consumption increase

Engineering Contradiction:
Improvetransmission qualityVSAvoidprocessing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent merges monitoring operations for passive streams into aggregated checks rather than individual monitoring. This combining reduces the total number of monitoring operations and processing time required, while still ensuring transmission quality is maintained through periodic aggregated assessments and immediate individual monitoring when streams become active.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent segments monitoring intensity by stream status: active streams receive comprehensive individual monitoring to ensure transmission quality, while passive streams receive lighter aggregated monitoring. This segmentation reduces overall processing time and energy consumption while maintaining quality assurance for streams that actually require it.

Inventive Principle:
Principle #1Segmentation
