Solution Overview

Problem

Existing media signal communication technologies face challenges in achieving high-quality media signal transmission over imperfect electromagnetic pathways, particularly in environments with attenuation, reflections, and interference, leading to unsatisfactory human perception and increased costs due to video compression artifacts and limited bit-serial media transport resilience.

Innovation Solution

Implementing a Spread Spectrum Direct Sequence-Code Division Multiple Access (SSDS-CDMA) system for media interfaces that synchronously encodes media signal samples using orthogonal Code Books, allowing for robust transmission over multiple electromagnetic pathways, adapting to varying EM path qualities and minimizing perceptible errors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If video compression is applied to reduce bandwidth, then data transmission efficiency is improved, but video quality deteriorates due to compression artifacts

Engineering Contradiction:

Improvedata transmission efficiencyVSAvoidvideo quality

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The patent divides the video signal into multiple independent color channels (luma, chroma, and alpha channels) that are transmitted separately over different electromagnetic pathways. This segmentation allows each channel to be optimized for its specific characteristics, avoiding the need for lossy compression while maintaining high video quality and enabling efficient parallel transmission.

Inventive Principle:

Principle #1Segmentation

2Device complexity

If bit-serial media transport is used to simplify implementation, then device complexity is reduced, but resilience to EM path defects deteriorates

Engineering Contradiction:

Improveimplementation complexityVSAvoidresilience to EM path defects

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent transitions from serial transmission to parallel transmission by sending multiple color channels simultaneously over multiple electromagnetic pathways. This dimensional change from time-serial to space-parallel transmission dramatically improves resilience to EM path defects, as failures in one pathway do not affect others, while maintaining relatively simple implementation through independent channel processing.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Reliability

If multiple electromagnetic pathways are used to improve resilience, then reliability is improved, but device complexity increases

Engineering Contradiction:

Improveresilience to EM path defectsVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent employs multiple electromagnetic pathways that can serve dual purposes: primarily for parallel color channel transmission to improve reliability and video quality, and secondarily as independent fallback options if any single pathway fails. This multi-functionality increases resilience while managing system complexity through unified channel processing architecture.

Inventive Principle:

Principle #6Universality (Multi-functionality)
