SBTV
ISDB-T International, or SBTVD, short for Sistema Brasileiro de Televisão Digital ( en, 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 w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ISDB-T
Integrated Services Digital Broadcasting (ISDB; Japanese: , ''Tōgō dejitaru hōsō sābisu'') is a Japanese broadcasting standard for digital television (DTV) and digital radio. ISDB supersedes both the NTSC-J analog television system and the previously used MUSE Hi-vision analog HDTV system in Japan. An improved version of ISDB-T (ISDB-T International) will soon replace the NTSC, PAL-M, and PAL-N broadcast standards in South America and the Philippines. Digital Terrestrial Television Broadcasting (DTTB) services using ISDB-T started in Japan in December 2003, and since then, many countries have adopted ISDB over other digital broadcasting standards. A newer and "advanced" version of the ISDB standard (that will eventually allow up to 8K terrestrial broadcasts and 1080p mobile broadcasts via the VVC codec, including HDR and HFR) is currently under development. Countries and territories using ISDB-T Asia * * (officially adopted ISDB-T, started broadcasting in digital) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ginga-J
Ginga is the middleware specification for the Nipo-Brazilian Digital Television System (SBTVD, from the Portuguese ''Sistema Brasileiro de Televisão Digital''). Ginga is also ITU-T Recommendation for IPTV Services. It is also considered in ITU-T recommendations for Cable Broadcast services (ITU-T J.200 Recommendation series: Rec. ITU-T J.200, Rec. ITU-T J.201 and Rec. ITU-T J.202) and for Terrestrial Broadcast services by ITU-R BT.1889, ITU-R BT.1699 and ITU-R BT.1722. Ginga was developed based on a set of standardized technologies but mainly on innovations developed by Brazilian researchers. Its current reference implementation was released under the GPL license. Ginga is divided into two main integrated subsystems, which allow the development of applications following two different programming paradigms. Those subsystems are called Ginga-NCL (for declarative NCL applications) and Ginga-J (for imperative Java applications). In the case of the Brazilian Terrestrial Digital TV Sy ...

Broadcast Markup Language
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. The text contains news, sports, weather forecasts, emergency warnings such as Earthquake Early Warning, etc. free of charge. It was finalized in 1999, becoming ARIB STD-B24 Data Coding and Transmission Specification for Digital Broadcasting. The STD-B24 specification is derived from an early draft of XHTML 1.0 strict, which it extends and alters. Some subset of CSS 1 and 2 is supported, as well as ECMAScript. Example BML header: Since version 1.0 in 1999, BML standard has gone through several revisions, and , it is on version 5.0. However, due to a large installed user base of receivers which only support the original 1.0 specification, broadcasters are not able to introduce new features def ...

ATSC
Advanced Television Systems Committee (ATSC) standards are an American set of standards for digital television transmission over terrestrial, cable and satellite networks. It is largely a replacement for the analog NTSC standard and, like that standard, is used mostly in the United States, Mexico, Canada, and South Korea. Several former NTSC users, such as Japan, have not used ATSC during their digital television transition, because they adopted other systems such as ISDB developed by Japan, and Digital Video Broadcasting, DVB developed in Europe, for example. The ATSC standards were developed in the early 1990s by the Grand Alliance (HDTV), Grand Alliance, a consortium of electronics and telecommunications companies that assembled to develop a specification for what is now known as HDTV. The standard is now administered by the Advanced Television Systems Committee. It includes a number of patented elements, and licensing is required for devices that use these parts of the stan ...

E-government
E-government (short for electronic government) is the use of technological communications devices, such as computers and the Internet, to provide public services to citizens and other persons in a country or region. E-government offers new opportunities for more direct and convenient citizen access to government and for government provision of services directly to citizens. The term consists of the digital interactions between a citizen and their government (C2G), between governments and other government agencies (G2G), between government and citizens (G2C), between government and employees (G2E), and between government and businesses/commerces (G2B). E-government delivery models can be broken down into the following categories:Jeong Chun Hai @Ibrahim. (2007). ''Fundamental of Development Administration.'' Selangor: Scholar Press. This interaction consists of citizens communicating with all levels of government (city, state/province, national, and international), facilitat ...

Information Society
An information society is a society where the usage, creation, distribution, manipulation and integration of information is a significant activity. Its main drivers are information and communication technologies, which have resulted in rapid information growth in variety and is somehow changing all aspects of social organization, including education, economy, health, government, warfare, and levels of democracy. The people who are able to partake in this form of society are sometimes called either computer users or even digital citizens, defined by K. Mossberger as “Those who use the Internet regularly and effectively”. This is one of many dozen internet terms that have been identified to suggest that humans are entering a new and different phase of society. Some of the markers of this steady change may be technological, economic, occupational, spatial, cultural, or a combination of all of these. Information society is seen as a successor to industrial society. Closely relat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Divide
The digital divide is the unequal access to digital technology, including smartphones, tablets, laptops, and the internet. The digital divide creates a division and inequality around access to information and resources. In the Information Age in which information and communication technologies (ICTs) have eclipsed manufacturing technologies as the basis for world economies and social connectivity, people without access to the Internet and other ICTs are at a socio-economic disadvantage, for they are unable or less able to find and apply for jobs, shop and sell online, participate democratically, or research and learn. Historical background The historical roots of the digital divide in Europe reach back to the increasing gap that occurred during the early modern period between those who could and couldn't access the real time forms of calculation, decision-making and visualization offered via written and printed media. Within this context, ethical discussions regarding the relatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital TV
Digital television (DTV) is the transmission of television signals using digital encoding, in contrast to the earlier analog television technology which used analog signals. At the time of its development it was considered an innovative advancement and represented the first significant evolution in television technology since color television in the 1950s. Modern digital television is transmitted in high-definition television (HDTV) with greater resolution than analog TV. It typically uses a widescreen aspect ratio (commonly 16:9) in contrast to the narrower format of analog TV. It makes more economical use of scarce radio spectrum space; it can transmit up to seven channels in the same bandwidth as a single analog channel, and provides many new features that analog television cannot. A transition from analog to digital broadcasting began around 2000. Different digital television broadcasting standards have been adopted in different parts of the world; below are the more widely ...
