Abstract
When a large-scale disaster occurs, NHK can carry out safety information broadcasting. It is important to gather information efficiently from a stricken area to NHK. We report two types of safety information gathering system using cellular packet communications network. One system is a mailbox that can send safety information to NHK just by pressing a transmitting button using a built-in camera in the mailbox. The other system uses a cellphone and can register individual safety information on homepage of NHK by reading special QR code which permits one-time access.
