| Great work. What is the data size and network bandwidth to send multimedia disaster information? Thanks! |
‘CAP (Commen Aelrting Protocol)’ is used to send multimedia disaster information, and the size of the file is within 10kb. Of course, “multimedia information” is not directly included in the CAP, but “link information” is sent to access the information. The format (eg, text, image, voice) applied varies depending on the medium, and in the case of'image', files within 500kb can be downloaded through a link.
The meaning of 'Nework bandwidth' is not well understood, but the system built through this study can be used both in the 'communication network (including 5G)' and 'the broadcasting network (including UHD)'. |

| How far has the system been built? Have some subsystems been applied to the actual field？ |
About 80% of the systems built through this study have been built, and are currently undergoing field tests. Of course, we are only checking the possibility for some disasters, not all disasters.
After that, expansion projects may be possible depending on the results of field tests and the will of government departments. |

| How about the security of this system? |
The system that is built through this research is being managed through 'user accounts'. It is also built as a system for use in the Korean administrative network (closed network). However, a more robust security system is required for practical application. |

| I wonder if the disaster-related multimedia information that you think is most useful during a disaster in your paper is different for each disaster. If it is different, what is a typical example? |
Thank you for your question. As inquired, useful multimedia content may vary depending on the disaster. In particular,'images' in the form of 'pictograms' are more efficient than 'text' for disasters that require 'emergency' (eg. earthquake, fire, etc.). |
