Resumen:

The deployment of digital TV in Uruguay is ongoing, following the ISDB-Tb standard. The channels allocation process was completed,and after the adoption of a testing protocol, the introduction of decoders and receivers began in early 2014. Testing their compliance with the standards is of paramount importance in order to foster migration towards it and to provide a platform to local developers. The government committed the School of Engineering and the Software Testing Centre to the elaboration of the testing protocol. This article reports the key aspects of this work: the analysis of the standards, the definition of a type approval protocol and the experience gained by applying the testing procedures. Its goal is to share the experience and contribute to the improvement of the digital TV adoption process, hopefully aiding to avoid some problems that were detected during this work, both in regulation and in devices compliance to the standards.Keywords: Digital Television, ISDB-T, TV Receivers Testing.


El despliegue de la televisión digital en Uruguay está en curso, siguiendo el estándar ISDB-Tb. Ya se completó el proceso de asignación de canales y, después de aprobado un protocolo de homologación, se ha comenzado a importar receptores o decodificadores desde principios de 2014. La certificación es de capital importancia para acelerar la migración y para brindar una plataforma a los desarrolladores locales. El presente artículo resume los aspectos clave de este trabajo: el análisis de las normas, la elaboración del Protocolo de Homologación y la experiencia obtenida en la aplicación de las pruebas. Su objetivo es compartir estas experiencias para contribuir en los procesos de adopción de la TV digital, con lo que se espera ayudar a que otros países o actores puedan evitar problemas de compatibilidad o cumplimiento de las normas que aparecieron durante este trabajo, tanto en la regulación como en los dispositivos ensayados.
