La televisión nacional, el apagón analógico y evolución hacia la televisión digital terrestre (TDT)

Abstract

The first time that a television shows was broadcasted in Ecuador was in 1959, becoming one of the main sources of entertainment and information for Ecuadorian people. Through the passing of the years the television was evolving, improving the quality in scenographies and implementing new technologies in lights, equipments of recording, editing and reproduction of audio and video. However, technology used by analog transmission systems for national television (air signal) had not changed since the adoption of the US NTSC released in the late 1950s. On March 26th 2010, the government of Ecuador signed an agreement that included technical cooperation and training with the governments of Japan and Brazil, thus initiating the process of introducing the ISDB-Tb system, which is one of the five digital terrestrial television or better known as DTT. The purpose of this thesis is to show the benefits that the television media will gain due to the change in how the transmissions will change from analogue to digital with the implementation of DTT, which seeks to improve signal quality (video/audio), interactivity in real time with viewers and integration with new ways of reception devices such as mobile devices (cell phones and tablets) using adapters that decode the signal.
