ISDB-T International, also known in Brazil as Sistema Brasileiro de Televisão Digital (SBTVD; English: Brazilian Digital Television System), 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 2 December 2007, in São Paulo, Brazil.[1][2]
It is similar to ISDB-T, except it utilizes the H.264 video codec rather than MPEG-2, and replaces BML with Ginga—a middleware supporting Nested Context Language (NCL) and Java-based interactive TV applications.
The ISDB-T International standard was developed as SBTVD by a study group coordinated by the Brazilian Ministry of Communications and was led by the Brazilian Telecommunications Agency (ANATEL) with support from the Telecommunication's Research and Development Centre (CPqD). The study group was composed of members of ten other Brazilian ministries, the National Institute for Information Technology (ITI), several Brazilian universities, broadcast professional organizations, and manufacturers of broadcast/reception devices. The objective of the group was to develop and implement a digital terrestrial television standard in Brazil, addressing not only technical and economical issues, but also and mainly mitigating the digital divide, that is, to promote inclusion of those living apart from today's information society. Another goal was to enable access to e-government, i.e. to make government closer to the population, since in Brazil 95.1% of households have at least one TV set.[3]
In January 2009, the Brazilian-Japanese study group for digital TV finished and published a specification document joining the Japanese ISDB-T with Brazilian SBTVD, resulting in a specification now called "ISDB-T International". ISDB-T International is the system that is proposed by Japan and Brazil for use in other countries in South America and around the world.[4]
