DVB-T2

ABSTRACT
In December 2011, Colombia updated its national Digital Terrestrial Television (DTT) standard from DVB-T to DVB-T2, the sec-ond generation of the DVB (Digital Video Broadcasting) project.DVB-T2 is the current state-of-the art DTT system in the world, and it brings very significant improvements in terms of capacity, robustness and flexibility compared with its predecessor. This paperanalyzes potential DVB-T2 transmission modes to optimize existing DTT network designs of Colombia, originally made for DVB-T, analyzing the trade-offs between capacity, coverage level and SingleFrequency Network (SFN) size. Network plan-ning results had been performed with a professional DTT network planning tool based on the first deployment phase of the DTT network of the public national TVbroadcaster RTVC. Compared with the initial DVB-T design, DVB-T2 can increase the national covered population up to 7.3%, or offer 70.26% more of capacity transmission, or increase the SFN size up to 135%keeping the total power transmission and the geographic distribution of the transmitters.

RESUMEN
En diciembre de 2011, Colombia decidió actualizar el estándar de Televisión Digital Terrestre (TDT) DVB-T a DVB-T2, la segun-da generación de la familia de estándares TDT delforo DVB (Digital Video Broadcasting). DVB-T2 es la actual base tecnoló-gica de los sistemas TDT en el mundo, el cual ofrece significativas mejoras en capacidad, robustez, flexibilidad comparado consu predecesor.
En este artículo se analizan potenciales modos de transmisión DVB-T2 para actualizar los existentes diseños de red en Co-lombia, originalmente elaborados para DVB-T, estableciendo lasposibles ganancias en capacidad de transmisión, cobertu-ra y tamaño de red SFN. Los resultados de planificación de red han sido desarrollados con una herramienta software profe-sional considerando la...
