Emergency Alert Receiver Segmentation for Rich Media
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital broadcasting systems lack the capability to provide detailed information such as still images and moving images alongside simple text-based information during emergencies, limiting the effectiveness of emergency information dissemination.
Innovation Solution
A receiving apparatus and data processing method that utilize a digital broadcast signal to present detailed emergency information by incorporating control information, allowing for the transmission and display of rich media content like still images and moving images through a transmitting apparatus and emergency alert application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If simple text-based emergency information is transmitted through digital broadcasting, then the system complexity remains low and transmission is straightforward, but the information detail and visual impact are insufficient
Solution Approach 1:
The emergency information transmission is divided into two segments: control information (text-based alerts, instructions) and detailed information (still images, moving images). The receiver processes control information immediately while fetching detailed information separately, allowing comprehensive information delivery without requiring the entire system to handle complex media simultaneously.
Solution Approach 2:
The system transitions from one-dimensional text-based information to multi-dimensional information delivery by adding visual dimensions (still images and moving images) while maintaining the original text-based control information channel. This allows the system to preserve simplicity in the control channel while enriching the information delivery through additional visual dimensions.
2Loss of information
If detailed information such as still images and moving images is included in emergency information, then the information comprehensiveness is improved, but the data transmission load and processing requirements increase
Solution Approach 1:
The information stream is segmented into control information and detailed information. Control information is transmitted and processed immediately for urgent alerts, while detailed information (images, videos) is transmitted separately and processed on-demand by the receiver, reducing peak transmission load and allowing flexible processing based on receiver capabilities.
Solution Approach 2:
The transmitter prepares and transmits control information in advance that contains references or triggers for detailed information. The receiver uses this control information to determine what detailed information to fetch and process, allowing preliminary preparation of critical alert data while deferring heavier media processing until necessary.
