Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If digital broadcast systems transmit large amounts of video/audio data, then HD images and additional services are provided, but data transmission efficiency and network robustness deteriorate

Engineering Contradiction:
Improveamount of video/audio dataVSAvoiddata transmission efficiency
Core Design Contradiction:
Quantity of substanceVSProductivity

Solution Approach 1:

The broadcast signal is divided into multiple PLP (Physical Layer Pipe) structures, each capable of carrying different types and amounts of data. This segmentation allows efficient transmission of large video/audio data quantities while maintaining overall transmission efficiency through optimized resource allocation across multiple parallel channels.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a hierarchical structure with multiple dimensions: PLP level, service level, and network level. This multi-dimensional organization enables simultaneous handling of large data quantities while maintaining transmission efficiency through layered management and optimized routing at each level.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Quantity of substance

If digital broadcast systems transmit large amounts of video/audio data, then HD images and additional services are provided, but network robustness deteriorates

Engineering Contradiction:
Improveamount of video/audio dataVSAvoidtransmission/reception network robustness
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

Different PLPs are assigned different robustness characteristics based on their specific requirements. Critical data can be transmitted through more robust PLPs with stronger error correction, while less critical data uses PLPs with higher efficiency but lower robustness. This local optimization maintains overall network robustness while supporting large data transmission.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system incorporates forward error correction (FEC) and redundancy mechanisms in advance within the PLP structure. This beforehand cushioning ensures that even when transmitting large amounts of data, the network maintains robustness against transmission errors and interruptions.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Quantity of substance

If digital broadcast systems transmit large amounts of video/audio data, then HD images and additional services are provided, but network flexibility deteriorates

Engineering Contradiction:
Improveamount of video/audio dataVSAvoidnetwork flexibility
Core Design Contradiction:
Quantity of substanceVSAdaptability or versatility

Solution Approach 1:

The PLP structure enables dynamic allocation and reconfiguration of transmission resources. Each PLP can be independently configured and adjusted based on real-time requirements, allowing the network to maintain flexibility while handling large data quantities. The system can adaptively modify PLP parameters, routing, and resource allocation during operation.

Inventive Principle:
Principle #15Dynamics

4Adaptability or versatility

If hybrid broadcasting using terrestrial broadcast networks and the Internet is implemented, then future broadcast services are supported, but system complexity increases

Engineering Contradiction:
Improvesupport for future broadcast servicesVSAvoidsystem architecture complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The PLP-based architecture serves as a universal framework that can handle both terrestrial broadcast and Internet-based transmissions through a unified structure. This multi-functionality reduces overall system complexity by providing a single adaptable platform rather than separate systems for different transmission modes.

Inventive Principle:
Principle #6Universality (Multi-functionality)
