Diseño e implementación de una aplicación interactiva basada en Ginga-NCL para televisión digital enfocada en la información del clima

Abstract

Through the ISDB-Tb standard adopted in Ecuador for digital terrestrial television, the viewer is able to receive programming with better audio and video quality; incorporating mobility and interactivity, the latter can display complementary and interesting information at any time or synchronize with a given program. Interactive applications are programs that are stored on the Set Top Box and run on the middleware Ginga, software layer that allows the development of applications using the Java language or NCL. This Titling Project focuses on the creation of an interactive application that displays the different climatic conditions in various cities of Ecuador, in it, each viewer is able to decide whether or not to access information through remote control. The application presented uses Ginga-NCL and LUA for the climatic conditions of different websites. To display weather data, each site may contain HTML source code or use an RSS feed in XML format, however, due to HTML has a number of very large characters, a file in C # is generated to remove formatting tags
