Ginga can be adapted for digital radio interactivity

A prototype application was successfully transmitted over digital radio

Standards for digital radio interactivity are feasible in Latin America

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.
