Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing AVRs with 8K video capability are limited to routing 8K video streams to only one display device, failing to support multizone video distribution, which was a key feature of previous models, and face design challenges due to the vast quantities of data required for 8K video streams.

Innovation Solution

A video-switching system with a novel architecture that includes multiple transceivers, such as 2:2 and 4:1 transceivers, connected by a controller to enable simultaneous routing of multiple 8K video streams from multiple inputs to multiple outputs, ensuring cost-effective and efficient multizone distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a single 8K video chipset is used in the AVR, then 8K video capability is achieved, but multizone video distribution is lost

Engineering Contradiction:

Improvevideo resolution capabilityVSAvoidmultizone distribution capability

Core Design Contradiction:

Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent divides the video routing function into multiple independent transceiver modules (first transceivers and second transceivers). Each transceiver handles specific routing tasks, allowing the system to process multiple 8K video streams simultaneously and distribute them to different zones while maintaining cost-effectiveness.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If multiple 8K video chipsets are connected to enable multizone distribution, then multizone capability is restored, but electronic hardware costs increase

Engineering Contradiction:

Improvemultizone distribution capabilityVSAvoidhardware cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent combines multiple transceivers into a unified video switching system architecture. By integrating first transceivers (connected to inputs) and second transceivers (connected to outputs) into a coordinated system controlled by a single controller, the patent achieves multizone 8K distribution without requiring separate 8K chipsets for each zone, thereby reducing overall hardware costs.

Inventive Principle:

Principle #5Merging (Combining)

3Productivity

If multiple 8K video chipsets are used for multizone routing, then simultaneous video distribution is enabled, but heat dissipation increases

Engineering Contradiction:

Improvesimultaneous video stream routing capabilityVSAvoidheat dissipation

Core Design Contradiction:

ProductivityVSLoss of energy

Solution Approach 1:

By segmenting the video processing workload across multiple specialized transceivers rather than using multiple full-featured 8K chipsets, the system reduces the power consumption and heat generation of each individual component while maintaining the overall capability to route multiple 8K streams simultaneously.

Inventive Principle:

Principle #1Segmentation
