Abstract

Digital Video Broadcasting (DVB) es un consorcio formado por industriales de los medios de comunicación,que está integrado por radiodifusores, fabricantes, operadores de redes, desarrolladores de software y organismosreguladores. El consorcio fue creado con el fin de definir las normas técnicas para estandarizar todos los aspectosrelacionados con la prestación de servicios de televisión digital. El estándar DVB ha sido adoptado en Europa,Oriente Medio, Suráfrica y Australasia. Adicionalmente, el estándar DVB fue seleccionado en Colombia y Panamácomo el sistema de transmisión de televisión digital terrestre (DVB-T/T2). El estándar DVB es un conjunto deespecificaciones que permiten la integración de información multimedia para proveer servicios de información,educación, negocios y entretenimiento. La implementación de DVB requiere de acuerdos entre los radiodifusores,operadores de redes y fabricantes en la definición de los parámetros de operación, además de tener en cuentalas normativas gubernamentales. Este artículo presenta un resumen de los principales elementos definidos en elestándar DVB-T/T2, basado en los documentos guía elaborados por el consorcio DVB, e incluye algunas de lasacciones tomadas durante el proceso de implementación de DVB-T/T2 en Colombia.

Highlights

  • The Digital Television (DTV) market was a vertical one

  • There are a wide field of applications of Digital Video Broadcasting (DVB)-T technologies in order to exploit the capability of all possible underlying technologies; such as a data transmission technique

  • In Zamudios presentation on 6 April 2011, the CNTV defined a strategy plan for deploying DVB-T in Colombia based on the following points: a) Communication to users, industry and manufacturers; b) Spectrum Planning; c) New Single Frequency Plan; d) digital terrestrial television (DTTV) coverage for national public television; e) Extending coverage of the television signal; f) Minimum technical requirements for TV and decoders; g) Regulation and normativity for open TV operators, and h) European Union Cooperation

Summary

Introduction

The Digital Television (DTV) market was a vertical one. The broadcasters rented the set-top boxes to the consumer as part of the subscription agreement. At the time of this writing, there are four main open standard systems for digital terrestrial television (DTT) broadcasting. In Japan, the Terrestrial Integrated Services Digital Broadcasting (ISDB-T) system is standardised by the Association of Radio Industries and Businesses (ARIB). DVB-T is a technical standard that specifies the framing structure, channel coding and modulation for digital terrestrial television (DTTV) broadcasting, available at http://www. A second generation, DVB-T2 increases the capacity of DTT of at least 30%, in comparison with the DBV-T (DigiTAG 2009) It provides new services along with three new bandwidths, and reception in portable and mobile devices. An overview of key elements – in technical specifications – is compiled from DVB-T documents, including minor information on DVB-T2, along with action taken regarding the release of DVB-T2 in Colombia
