Emergency Information Display Positioning in Digital Broadcasts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Emergency information may not be displayed at appropriate positions during emergencies when communicated through multiple methods, leading to a need for effective positioning solutions.
Innovation Solution
A receiving apparatus and data processing method that acquire metadata from digital broadcast signals, including emergency information and display position information, to determine and display emergency information at distinct positions on the screen, and a transmitting apparatus that generates and transmits metadata with display position information for emergency information embedded in uncompressed video data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If emergency information is communicated through multiple methods (metadata and uncompressed video data), then the reliability of emergency information transmission is improved, but the display position management becomes complex and emergency information may not be displayed at appropriate positions
Solution Approach 1:
The patent introduces display position information as an intermediary element within the metadata that mediates between the emergency information content and the display presentation. This intermediary carries positioning instructions that enable the receiving apparatus to correctly place emergency information on the screen, resolving the complexity of managing multiple transmission methods while maintaining appropriate display positions
2Illumination intensity
If emergency information is embedded in uncompressed video data, then the visibility and clarity of emergency information is improved, but the flexibility in displaying additional emergency information at different positions is reduced
Solution Approach 1:
The patent segments emergency information into two distinct components: first emergency information transmitted through metadata with flexible positioning capabilities, and second emergency information embedded in uncompressed video data for high visibility. This segmentation allows each component to fulfill its specific function optimally while working together to provide comprehensive emergency information display

AI summary
This technology relates to a receiving apparatus, a transmitting apparatus, and a data processing method for displaying emergency information communicated in an emergency at appropriate positions.The receiving apparatus acquires metadata transmitted by a digital broadcast signal, the metadata including first emergency information required to be announced urgently and display position information indicating whether there is second emergency information embedded in uncompressed video data, the display position information further indicating, if the second emergency information is embedded in the uncompressed video data, the display position of the second emergency information on a screen. The receiving apparatus processes the metadata to determine whether the second emergency information is embedded in the uncompressed video data and, if the second emergency information is embedded in the uncompressed video data, displays the first emergency information at a position different from the display position of the second emergency information on the screen. This technology applies to television receivers, for example.
