Estudio comparativo de los estándares de radiodifusión digital terrena orientado a definir su aplicabilidad en el Ecuador.

Abstract

The present investigation is a Comparative Study of the Earth Digital Broadcasting Standards oriented to define its applicability in Ecuador, which has been done by students from Electronic Engineering in Telecommunications and Networks School. The analytic and comparative methods have been used through the investigation of the four earth digital broadcasting standards: Digital Audio Broadcasting “DAB”, In Band on Channel “IBOC”, Digital Radio Mondiale “DRM”, and finally Integrated Service Digital Broadcasting- Terrestrial Sound Broadcasting “ISDB-TSB”, in addition characteristics of the analogical radio in Ecuador have developed. Although is certain that in a general way the digital radio would allow in any of its formats a meaningful improvement in quality and distribution, from the study it is derived that DIGITAL RADIO MONDIALE “DRM” with an 88% is the system that better would adapt in the Ecuadorian territory for the adoption of the new digital format, because of a several of its conditions such as: Its transmission capacity in a hybrid way during the transition period, operation over the same frequency bands used currently by the analogical radio. Its adaptability capacity from analogical equipment to the new digital format, among others. It is suggested that the Digital Radio Mondiale “DRM” be adapted for digital radio in Ecuador, or if is not so, a system that permit the transmission in a hybrid way, since this would facilitate the transition process from analogical radio to digital one and its development in Ecuador.
