    Prototype of a Centralized Alert and Emergency System for Digital Terrestrial Television in Ecuador
    (Spriger Nature, 2021) Achig Balarezo, Rosario
    Latin America is living the migration towards the digital terrestrial television (DTT) with the ISDB-Tb standard. Some countries have even had the analog blackout. In relation to the Emergency Warning Broadcast System (EWBS), the process of transmission and reception is defined. In recent years, tests have been coordinated for the process of implementing EWBS for DTT. The Common Alert Protocol (CAP) allows emergency alerts to be exchanged between different communication systems. This article presents the implementation of a CAP module in a Spatial Data Infrastructure for risk management and integration of the EWBS for DTT in a single platform for emergency alerts. A web service that contains the codes representing the cantons of Ecuador was obtained, selected through the use of a map viewer and integrated with an application that processes this information and generates the alert to be transmitted via DTT. The main objective is the storage of the information in a database, and a WEB RSS service that contains the information in conformance with CAP format. A series of experiments show successful outcomes.

    Spatial data infrastructure as the core for activating early alerts using EWBS and interactive applications in digital terrestrial television
    (Springer Verlag, 2019) Morocho Zurita, Carlos Villie; Achig Balarezo, Rosario; Santander Jaramillo, Darwin Fabian; Bautista Llivisaca, Mateo Sebastian; Achig Balarezo, Rosario
    Integrated Services Digital Broadcasting Terrestrial (ISDB-T) is the standard adopted in Ecuador since 2010. There is a lack of proposals for taking advantage of communication alternatives with citizens, which the new digital technology will bring. The speed for alerting the community about dangers associated with natural hazards is an essential issue. There are many devices to alert population but none of them has the level of dissemination within households as the television does. This paper presents a software solution for early alert using the UCuenca-SDI (Spatial Data Infrastructure) core to activate an Emergency Warning Broadcasting System (EWBS) protocol in a Digital TV. The solution has two components (a) A schema to integrate the trigger module into the SDI, where the activation code is generated for EWBS. (b) An interactive app software developed over GINGA, where citizens can access …
