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.

Being part of the so-called “Pacific Ring of Fire” and “Belt of Low Pressure,” Ecuador is located in one area most likely to suffer seismic, volcanic, and hydrometeorological threats, which make it possible to catalog as a country with a high vulnerability. For this reason, the use of alert systems such as Emergency Warning Broadcasting System EWBS is necessary for the face of one of these threats, which can be implemented in analog and digital broadcast signals such as Digital Terrestrial Television. In an emergency, the receivers compatible with the EWBS are currently the decoders or digital televisions that include this system. They turn on automatically and emit a visual and audible alert signal that gives time to the population to act more quickly to an event. This article presents the design proposal of a receiver that replicates the warning emergency alert EWBS for digital terrestrial television with the ISDB-Tb standard, through an institutional telephone PBX, implementing an IP telephony server that receives the EWBS system and replicates it to landlines, infocast systems, and mobile phones connected to it, thus avoiding a percentage of losses in the economic and human fields.

El presente artículo muestra una solución al desarrollo automático de aplicaciones interactivas Ginga-NCL para la Televisión Digital Terrestre, a partir de plantillas prediseñadas. Productores de televisión y gente relacionada con este medio de comunicación masivo, no conocen o simplemente no tienen las herramientas necesarias para la creación de aplicaciones interactivas, en muchos casos ni siquiera se conoce la existencia de una plataforma para el desarrollo de las mismas. Es por esta razón que se propone una metodología totalmente nueva y amigable para el usuario, la cual permita generar aplicaciones interactivas sin tener el conocimiento técnico ni las habilidades de programación que implica su creación. La reducción del tiempo en la generación de aplicaciones, disminución de capital de inversión en la preparación y adiestramiento del personal, cambios on-air en la programación interactiva del canal de televisión, son algunos de los resultados que trae consigo este sistema.

The results of transmission and reception broadcast tests of the Emergency Warning Broadcast System (EWBS) for Digital Terrestrial Television in the city of Quito-Ecuador with the ISBD-T standard are presented in this paper, in coordination with government agencies and private companies. The system consists of an EWBS server developed and implemented by the authors, which modifies the text overlay message and the PSI tables for some-emergency-codes transmission, as established in the EWBS international harmonization document, while re-configuring the multiplexing and transmission stage of the television station. The tests were carried out in two stages, on the one hand working directly with the multiplexers and modulators of digital terrestrial television from Pichincha hill, and on the other hand from television station with a microwave transport network to Pichincha hill. It was possible make the activation of the EWBS receivers in the coverage region, select codes, and reception of the overlay message, with an nearly imperceptible delay in the complete system, within real time requirements.

In this work we present “DomoiTV”, a home automation system and its communication protocol with a graphic interface for the Brazilian digital terrestrial television standard ISDB-Tb.

The present article describes the creation of a MPEG-2 Transport Stream (TS)/Broadcast Transport Stream (BTS) Analyzer for Digital Television. This analyzer recognizes TS and BTS files in a decimal or hexadecimal format and it shows the components of the PSI (Program Service Information)/SI (Service Information) Tables, such as: Program Association Table (PAT), Program Map Table (PMT), Network Information Table (NIT), and Service Descriptor Table (SDT); in the case of the BTS files it also shows the content of the Transmission and Multiplexing Configuration (TMCC) table. The software has a package search system where you can look for a package through his PID (Program Identification) number or his package number. It also allows surfing between all the packages or the packages with the same PID number.

This paper describes the design and implementation of a system responsible of the automotive monitoring and diagnosis of a vehicle using the standard OBDII (On Board Diagnostics), a mobile application on the Android Platform and the implementation of a Web server developed using PHP (Hypertext Preprocessor). For the development a mobile terminal Samsung Galaxy ACE, a vehicle Kia Rio R 2013 and an BAFX OBDII Bluetooth communication device were used. Also a fault code simulator was implemented to allow the system's testing without the need of a real connection with the vehicle.

This article describes the analysis of return channel for digital terrestrial television (DTT), through the development of interactive application called Shopping Car buying and selling. Using the middleware Ginga-NCL, Lua and MySQL, to get evidence of the return path for the interactive application and determines the capacity of server performance.
