Requisitos para um r\'adio digital interativo no Brasil e Am\'erica Latina

Abstract

This article discusses the feasibility and requirements for using Ginga as the middleware of a Digital Radio System. Ginga was adopted by Brazil and several other countries in Latin America as the standard for interactivity in Digital TV (ISDB-T International). In this article the two digital radio standards being considered for adoption by Brazil are briefly presented, a discussion about the requirements for broadcast radio interactivity is presented, and finally a prototype of a Ginga interactive application for digital radio that was transmitted and received over the air using a digital radio standard is detailed.
