IP Transmission Emergency Notification Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The introduction of IP transmission schemes in digital broadcasting lacks a established technical scheme for providing advanced emergency notification services, which is essential for next-generation broadcasting systems.
Innovation Solution
The implementation of an IP transmission scheme that employs a section format or XML format for signaling information, including a protocol stack, ID system, and configuration of broadcast waves, with features like compulsory emergency activation flags and signaling systems to ensure reliable and efficient emergency notification services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an IP transmission scheme is introduced for next-generation digital broadcasting, then various advanced services and operation forms can be provided, but a technical scheme for emergency notification services has not been established
Solution Approach 1:
The patent applies preliminary action by establishing emergency notification service schemes in advance for IP transmission systems. The system pre-defines message formats, transmission protocols, and receiver response mechanisms before actual emergencies occur, ensuring that reliable emergency notification capabilities are ready when needed, rather than attempting to establish them during system operation
Solution Approach 2:
The patent implements universality by designing a multi-functional emergency notification system that can operate across different transmission schemes (MPEG2-TS and IP), different receiver states (powered on and powered off), and various message formats (CAP and proprietary). This universal approach allows the same system to provide emergency notifications regardless of the underlying transmission technology or receiver power state
2Reliability
If a receiver is specified to be powered on according to control signal even in power-off state, then emergency broadcasting service can be received, but energy consumption increases
Solution Approach 1:
The patent applies partial action by implementing selective wake-up mechanisms where receivers only partially activate their full functionality when emergency notifications are detected. The system uses wake-up signals to trigger minimal necessary operations for receiving and processing emergency messages, rather than fully powering on all receiver components, thus reducing energy consumption while ensuring emergency notification delivery
Solution Approach 2:
The patent introduces an intermediary wake-up signal mechanism that mediates between the powered-off state and full operation state. The wake-up signal acts as an intermediate step that alerts the receiver to emergency conditions and triggers selective activation of only the necessary subsystems needed for emergency notification reception, rather than immediately powering on the entire receiver
3Adaptability or versatility
If subtitle superimposed on video is displayed for emergency notification, then emergency information can be conveyed, but the notification method is limited compared to control signal-based approaches
Solution Approach 1:
The patent applies dynamics by implementing a flexible notification system that can dynamically switch between different notification methods (control signals, subtitles, audio alerts) based on the receiver state, emergency type, and user preferences. The system adapts its notification approach in real-time rather than using a fixed method, thereby maintaining notification effectiveness across diverse scenarios
4Ease of manufacture
If MPEG2-TS scheme is used for digital broadcasting, then established transmission standards are available, but emergency notification services cannot be provided in IP transmission schemes
Solution Approach 1:
The patent applies segmentation by separating the emergency notification service layer from the underlying transmission scheme. The system divides the notification functionality into independent components (message formatting, transmission protocols, receiver processing) that can be independently configured for different transmission schemes (MPEG2-TS or IP), allowing each scheme to be used without requiring complete service redesign

AI summary
To provide more advanced emergency notification service. An emergency notification control unit controls operations of respective units corresponding to an emergency notification service based on an emergency notification control signal transmitted through a broadcast wave of digital broadcasting using an IP transmission scheme, and thus a more advanced emergency notification service can be provided in digital broadcasting using an IP transmission scheme. The present technology can be applied to, for example, a broadcasting system including a transmitter and a receiver.
