Diseño de una infraestructura de Televisión Digital Terrestre con el estándar ISDB-Tb.

Abstract

The research had as objetive to establish an architecture for the transmission of Digital Terrestrial Television, several studies were taken referring to the subject that pose different infrastructures for the implementation of television channels, Using a methodology that by level of depth is descriptive, documentary application, analyzing the most used standards that currently exist the world: DVB-T (Digital Video Broadcasting Terrestrial), DVB-T2 (Digital Video Broadcasting Terrestrial 2) and ISDB-T (Terrestrial Integrated Services Digital Broadcasting). In order to understand the correct behavior of the ISDB-Tb (Terrestrial integrated Services Digital Broadcasting International) standard, it will start with the development and operation of the standard DVB-T standard used by most of Europe, Asia and Africa and according to several criteria the simplest of all . The main advantages of the ISDB-T standard will be described, and the main advantages of the new system will be defined, demonstrating that the ISDB-Tb standard allows the transfer of several programs in the 6 MHz bandwidth which can be up to four Or six programs requiring the video quality to which they will be transmitted, whether in SD, HD or LD, recommending that the new system of television transmission forces to the local and regional television channels to establish new strategies to provide the user quality content and be able to compete with national channels and be able to recover the investment.
