Development of a Gateway Server to Enhance Early Warning in Digital Terrestrial Television

This research addresses the analysis, design, development, and implementation of a Gateway Server aimed at decoding and retransmitting early warning messages within the context of digital terrestrial television services. It is crucial to highlight that Ecuador is a disaster-prone area susceptible to natural calamities. The Emergency Warning Broadcasting System is highly beneficial in disseminating information. However, due to its low popularity and certain limitations, developing a Gateway server becomes essential to notify users or clients through various mobile and desktop applications. The system is designed to be versatile and compatible with multiple platforms, including desktop and mobile devices, utilizing iOS and Android native services for notifications. Furthermore, a public server hosted on Digital Ocean, a user-friendly platform offering accessible Cloud Computing services, has been implemented. This server manages the logic related to users, tokens, device identifiers, and alert messages. These services result in a Gateway Server capable of interpreting early warning messages and administering alert distribution through APNs and Google FCM for mobile clients and through direct API consumption toward the server for desktop clients.
