| dbo:abstract | Sistema Brasileiro de Televisão Digital (SBTVD; deutsch Brasilianisches System für digitales Fernsehen), auch ISDB-Tb genannt, ist ein auf ISDB basierender Standard für Digitales Fernsehen. Er wurde am 2. Dezember 2007 gestartet. Der Unterschied zu ISDB besteht in der Nutzung von MPEG-4 als Kompressionsverfahren, gegenüber MPEG-2 bei ISDB. ISDB-Endgeräte sind von der Hardware mit SBTVD-Endgeräten identisch; sie unterscheiden sich nur in der Software. (de) ISDB-T International, or SBTVD, short for Sistema Brasileiro de Televisão Digital (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, as SBTVD. ISDB-T International is also called ISDB-Tb (ISDB-T Japanese standard, Brazilian version) and basically differs from original ISDB-T by using H.264/MPEG-4 AVC as a video compression standard (ISDB-T uses H.262/MPEG-2 Part 2), a presentation rate of 30 frames per second even in portable devices (ISDB-T, One seg, uses 15 frame/s for portable devices) and powerful interaction using middleware Ginga, composed by Ginga-NCL and Ginga-J modules (ISDB-T uses BML). 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 DTV (Digital TV) 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. 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. (en) SBTVD, abreviatura para Sistema Brasileiro de Televisão Digital (en español, Sistema Brasileño de Televisión Digital), (también llamado ISDB-Tb o ISDB-T Internacional) es un estándar técnico para transmisión de televisión digital terrestre utilizado en Brasil, Perú, Argentina, Chile, Venezuela, Ecuador, Costa Rica, Paraguay, Filipinas, Guatemala, Bolivia, Nicaragua, Uruguay y Honduras, basado en el estándar Japonés ISDB-T, lanzado en una operación comercial el 2 de diciembre de 2007, en São Paulo, Brasil. El estándar SBTVD fue desarrollado por un grupo de estudio coordinado por el Ministro Brasileño de Comunicaciones y fue liderado por la Agencia Brasileña de Telecomunicaciones (ANATEL) con el respaldo del Centro de desarrollo de investigación en Telecomunicaciones (CPqD). El grupo de estudio estuvo compuesto por miembros de otros diez ministerios brasileños, el Instituto Nacional para la Tecnología de la información (ITI), algunas universidades Brasileñas, organizaciones profesionales de difusión, y empresas constructoras de equipos de transmisión/recepción. El objetivo del grupo fue desarrollar e implementar un estándar de televisión digital terrestre en Brasil, dirigido no solamente a resolver cuestiones técnicas o económicas, sino también y principalmente, para mantener inclusión digital de aquellas personas que viven lejos de la actual "sociedad de información" y buscando un mecanismo técnico para el gobierno electrónico, esto es hacer que el gobierno sea más cercano a la población ya que en Brasil más del 95,1% de los hogares tiene al menos un aparato de televisión. SBTVD es también conocido como ISDB-Tb (versión brasileña del estándar japonés ISDB-T) y difiere básicamente del estándar original ISDB-T por el uso de H.264/MPEG-4 AVC como estándar de compresión de vídeo (ISDB-T usa el estándar H.262/MPEG-2 Parte 2), una velocidad de presentación de 30 imágenes por segundo, aún en dispositivos portátiles (mientras que ISDB-T, usa 15 imágenes por segundo) e interacción mediante el uso del middleware Ginga, compuesto de los módulos Ginga-NCL y Ginga-J (ISDB-T usa BML). En enero del año 2009, el grupo de estudio brasileño-japonés para la televisión digital finalizó y publicó una especificación, ahora denominada "ISDB-T Internacional". ISDB-T Internacional es el sistema que fue propuesto por Japón y Brasil a otros países de América del Sur y alrededor del mundo. (es) SBTVD, sigla para Sistema Brasileiro de Televisão Digital (conhecido também como ISDB-Tb), é um padrão técnico para teledifusão digital, criado no Brasil em parceria com o Governo do Japão seguindo o modelo ISDB (criado pela NHK e SONY em 1971). O ISDB-Tb é utilizado no Brasil e adotado recentemente no Peru, Argentina, Chile, Venezuela, Equador, Costa Rica, Paraguai, Filipinas, Bolivia, Nicarágua e Uruguai baseado no padrão japonês ISDB-T (ou apenas ISDB). Entrou em operação comercial em 2 de Dezembro de 2007 em São Paulo. O Japão utiliza o modelo original ISDB, que foi lançado em 2003. (pt) ISDB-T (англ. Integrated Service Digital Broadcasting - Terrestrial) — стандарт цифрового телевидения. Используется в Японии и странах Южной Америки, экспериментально на Филиппинах. (ru) ISDB-T国际又稱SBTVD，是巴西数字电视系统（葡萄牙語：Sistema Brasileiro de Televisão Digital）的简称，它是巴西、阿根廷、秘鲁、博茨瓦纳、智利、洪都拉斯、委内瑞拉、厄瓜多尔、哥斯达黎加、巴拉圭、菲律宾、玻利维亚、尼加拉瓜、萨尔瓦多和乌拉圭使用的数字电视广播技术标准，該標準基于日本的ISDB标准。ISDB-T国际于2007年12月2日在巴西圣保罗以SBTVD的名义投入商业运营。 ISDB-T国际标准是在的支持下由牵头、巴西通信部协调下的一个研究小组制定的。该研究小组由巴西其他10个部委、国家信息技术研究所、若干巴西大学、广播专业组织和广播/接收设备制造商组成。该小组的目标是在巴西制定和实施数字电视标准。 2009年1月，巴西-日本数字电视研究小组完成并公布了一份规范文件，它将日本的ISDB-T与巴西的SBTVD结合起来，形成了现在的ISDB-T国际规范。 (zh) |
