Solution Overview

Problem

The ATSC 3.0 broadcasting standard lacks an efficient system for prioritizing Non-Real-Time (NRT) data types such as ESG data and AEA-related data, leading to suboptimal bandwidth utilization and delayed delivery of critical information.

Innovation Solution

A system comprising NRT servers, a signaling server, and a broadcast gateway that prioritize NRT data based on urgency, relevance, and criticality, using a prioritization policy defined by a processor to assign priority levels and schedule transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If NRT data services are transmitted without prioritization in ATSC 3.0 broadcasting, then all data types can be transmitted equally, but critical information delivery is delayed and bandwidth utilization is suboptimal

Engineering Contradiction:

Improvebandwidth utilization efficiencyVSAvoiddelivery time of critical information

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent segments NRT data into different priority levels (high, medium, low) based on data type and urgency. The signaling server divides the data stream into prioritized groups, allowing critical data to be transmitted separately from less urgent data, thereby improving both bandwidth utilization and delivery time for critical information.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies different quality of service (QoS) treatments to different portions of the data stream based on their priority classification. High-priority data receives preferential treatment in terms of transmission scheduling and resource allocation, while lower-priority data receives standard treatment, optimizing overall system performance.

Inventive Principle:

Principle #3Local quality

2Reliability

If a prioritization system is implemented for NRT data, then critical information delivery is improved and bandwidth utilization is optimized, but system complexity increases

Engineering Contradiction:

Improvedelivery reliability of critical informationVSAvoidcomplexity of prioritization system

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The signaling server performs preliminary prioritization classification of NRT data before transmission. By pre-categorizing data into priority levels based on data type and urgency indicators, the system establishes transmission queues in advance, ensuring reliable delivery of critical information without requiring complex real-time decision-making during transmission.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces a signaling server as an intermediary component between the data source and the transmission system. This mediator handles the prioritization logic and queue management, isolating the complexity from the core broadcasting system while ensuring reliable critical information delivery through centralized control.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If priority levels are assigned to all NRT data, then transmission scheduling is optimized, but processing overhead increases

Engineering Contradiction:

Improvetransmission scheduling efficiencyVSAvoidprocessing overhead for priority assignment

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent applies prioritization selectively rather than uniformly to all NRT data. The system identifies and assigns priority levels primarily to data types that require timely delivery (such as emergency alerts and time-sensitive service information), while applying standard treatment to less critical data, thereby reducing processing overhead while maintaining scheduling efficiency for important data.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A system for prioritizing NRT data services within an ATSC 3.0 broadcasting standard includes NRT servers each configured to transmit NRT data; a signaling server operatively coupled to each of the NRT servers and configured to receive the NRT data and prioritize the received NRT data; and a broadcast gateway operatively coupled to the signaling server and configured to receive the prioritized NRT data from the signaling server and convert the prioritized NRT data for transmission to an exciter for ATSC 3.0 broadcasting. The signaling server includes a processor configured to prioritize the received NRT data to produce the prioritized NRT data by: defining a prioritization policy; identifying priorities of the received NRT data and assigning priority according to the prioritization policy across all of the received NRT data; and determining a priority schedule for broadcasting the received NRT data to provide the prioritized NRT data to the broadcast gateway.
