The standard ABNT NBR 15608 describes in further detail the parts of the digital television system that need clarifying, setting directives for implementation in a combination of mandatory and optional features. It can be seen as a refinement of the original specification documents focused on system implementation.
The standard was written by telecommunications and television experts from many countries with their works coordinated by the SBTVD Forum and cover in detail all the aspects of video and audio coding that applies to SBTVD. The complete document can be found and downloaded freely in English, Spanish and Portuguese at ABNT's website.
The SBTVD Forum is a non-profit organization of private and public companies responsible for the general aspects of Digital TV deployment in Brazil. The organization was founded in 2007 in order to address all technical issues regarding the upcoming SBTVD standard, also known as ISDB-Tb.
The operational guidelines aspects of the Brazilian Digital Terrestrial Television Standards are described in the following documents published by ABNT, the Brazilian Association of Technical Standards (Associação Brasileira de Normas Técnicas): [1] ABNT NBR 15608-1:2008 - Digital terrestrial television - Operational guideline - Part 1: Transmission ; ABNT NBR 15608-2:2008 - Digital terrestrial television - Operational guideline - Part 2: Video coding, audio coding and multiplexing; and ABNT NBR 15608-3:2008 - Digital terrestrial television - Operational guideline - Part 3: Multiplexing and SI/PSI Tables
The standard describes in further detail the parts of the digital television system that need clarifying, setting directives for implementation in a combination of mandatory and optional features. It can be seen as a refinement of the original specification documents focused on system implementation.
The standards are a flexible system allowing terrestrial broadcasters to choose from a variety of options to suit their various service environments. This allows the choice between fixed roof-top antenna, portable and even mobile reception of services. Broadly speaking the trade-off is of service bit-rate versus signal robustness. This way, operational guidelines play an important part in setting levels of performance and general paths for proper implementations by manufacturers and software developers.
The terrestrial digital television implementation is not only a technical and business challenge but also represents an effective means of giving access of the digital technology to all socio-economic segments of society. The upcoming work is the establishment of a test centre which is expected for the following months.
Brazilian digital television is in its early stages of development and implementation with a very promising future. Most of the component sub-systems are based on existing international standards, but used in an innovative and unique combination. The Brazilian DTTB system uses state-of-the-art technologies with no prejudice whatsoever to time-to-market of receivers in the one year range.
Economical aspects related to investments in broadcast equipment are also being carefully addressed. The implementation of DTTB in Brazil includes financing and special industrial policies that match the Latin America reality.
The ultimate goal of the whole process is to promote a smooth introduction of the free-to-air terrestrial digital television service with adequate levels of knowledge and confidence throughout the whole productive chain, with an ultimate positive impact to the Brazilian society.
These documents are also officially available at ABNT website.
Operational guidelines are interpretations of the technical standards aimed at the implementations required for a specific case. It also serves as a baseline approach to developers and manufacturers seeking compliance with the rest of the system.
The documents describing the operational guidelines are ABNT NBR 15608-1:2008 - Digital terrestrial television - Operational guideline - Part 1: Transmission; ABNT NBR 15608-2:2008 - Digital terrestrial television - Operational guideline - Part 2: Video coding, audio coding and multiplexing; and ABNT NBR 15608-3:2008 - Digital terrestrial television - Operational guideline - Part 3: Multiplexing and SI/PSI Tables
The Integrated Services Digital Broadcasting is a Japanese standard for digital television (DTV) and digital radio used by the country's radio and television networks. ISDB replaced NTSC-J analog television system and the previously used MUSE Hi-vision analogue HDTV system in Japan, and will be replacing NTSC, PAL-M and PAL-N in South America and the Philippines. Digital Terrestrial Television Broadcasting (DTTB) services using ISDB-T started in Japan in December 2003 and in Brazil in December 2007 as a trial. Since then, many countries have adopted ISDB over other digital broadcasting standards.
Digital terrestrial television in the United Kingdom encompasses over 100 television, radio and interactive services broadcast via the United Kingdom's terrestrial television network and receivable with a standard television set. The majority of digital terrestrial television (DTT) services, including the five former analogue channels, are broadcast free-to-air, and a further selection of encrypted pay TV services are also available.
ISDB-T International, ISDB-Tb or SBTVD, short for Sistema Brasileiro de Televisão Digital, is a technical standard for digital television broadcast used in Brazil, Argentina, Peru, Botswana, Chile, Honduras, Venezuela, Ecuador, Costa Rica, Paraguay, Philippines, Bolivia, Nicaragua, El Salvador and Uruguay, based on the Japanese ISDB-T standard. ISDB-T International launched into commercial operation on December 2, 2007, in São Paulo, Brazil, as SBTVD.
Broadcast Markup Language, or BML, is an XML-based standard developed by Japan's Association of Radio Industries and Businesses as a data broadcasting specification for digital television broadcasting. It is a data-transmission service allowing text to be displayed on a 1seg TV screen.
PAL-M is the analog TV system used in Brazil since February 19, 1972. At that time, Brazil was the first South American country to broadcast in colour. Colour TV broadcast began on February 19, 1972, when the TV networks Globo and Bandeirantes transmitted the Caxias do Sul Grape Festival. Transition from black and white to colour was not complete until 1978. Two years later, in 1980, colour broadcast nationwide in Brazil was commonplace.
DVB-T2 is an abbreviation for "Digital Video Broadcasting — Second Generation Terrestrial"; it is the extension of the television standard DVB-T, issued by the consortium DVB, devised for the broadcast transmission of digital terrestrial television. DVB has been standardized by ETSI.
Sky Picnic was a proposed pay television service to launch from BSkyB. It would have sat alongside Freeview and Top Up TV on the digital terrestrial television (DTT) platform in the United Kingdom. It was first proposed in 2007 and was cleared to launch in 2010; however BSkyB never officially launched the service, and it was ultimately superseded by the internet-based Now TV platform.
