Diseño y simulación de una aplicación interactiva turística para la ciudad de Quito utilizando MIDDLEWARE GINGA NCL del estándar ISDB-T/SBTVD para televisión digital.

Abstract

This work is based on Ginga Middleware technology standard pertaining to Integrated Services Digital Broadcasting with innovations developed in Brazil ISDBT -TB adopted by the country, to design and simulate an interactive application for the city tour of Quito using the declarative language NCL and Ginga VM equivalent to a Set- Top -Box. It begins with a brief description of the digital terrestrial TV standards, then presents the standard ISDBT along with innovations in Brazil that define standard called ISDBT -TB or the Brazilian digital TV SBTVD. Following is the architecture of Ginga Middleware components, properties and characteristics that allow the development of interactive applications. Next, we review concepts of interactivity , parameters for user interface design , and software tools available for application development , based on revised it comes to interface design considering the following steps: screen design , design transitions according to the action to perform , developing the interactive diagram , table of interactivity and selection of media objects . Once the design is set, sync, and control media elements through the NCL language instructions in Eclipse. Later the simulation on the virtual machine and verified the optimal functioning of the interactive application. Finally are displayed, analyzed the results to technical and economic level for drawing conclusions.
