SBTVD
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] |
Digital Rights Management
Digital rights management (DRM) is the management of legal access to digital content. Various tools or technological protection measures (TPM) such as access control technologies can restrict the use of proprietary hardware and copyrighted works. DRM technologies govern the use, modification, and distribution of copyrighted works (such as software and multimedia content), as well as systems that enforce these policies within devices. Laws in many countries criminalize the circumvention of DRM, communication about such circumvention, and the creation and distribution of tools used for such circumvention. Such laws are part of the United States' Digital Millennium Copyright Act (DMCA), and the European Union's Information Society Directive (the French DADVSI is an example of a member state of the European Union implementing the directive). DRM techniques include licensing agreements and encryption. The industry has expanded the usage of DRM to various hardware products, such as K ...

ABNT
The Brazilian Association of Technical Standards, usually rendered in Portuguese as Associação Brasileira de Normas Técnicas (ABNT) is a private non-profit organization and the normative body which is responsible for technical standards in Brazil, and intends to promote technological development in the country. Brazilian national standards published by the association are named ''Norma Brasileira Regulamentadora'' and abbreviated NBR. ABNT was founded in 1940. It was officially adopted by the Brazilian government in 1962. It is a founding member of the ''International Organization for Standardization'' (ISO), the Panamerican Standards Commission (COPANT) and the Asociación Mercosur de Normalización (AMN). ABNT is the exclusive representative of Brazil in the international organizations ISO ISO is the most common abbreviation for the International Organization for Standardization.

High-Definition Multimedia Interface
High-Definition Multimedia Interface (HDMI) is a proprietary audio/video interface for transmitting uncompressed video data and compressed or uncompressed digital audio data from an HDMI-compliant source device, such as a display controller, to a compatible computer monitor, video projector, digital television, or digital audio device. HDMI is a digital replacement for analog video standards. HDMI implements the EIA/CEA-861 standards, which define video formats and waveforms, transport of compressed and uncompressed LPCM audio, auxiliary data, and implementations of the VESA EDID. CEA-861 signals carried by HDMI are electrically compatible with the CEA-861 signals used by the Digital Visual Interface (DVI). No signal conversion is necessary, nor is there a loss of video quality when a DVI-to-HDMI adapter is used. The Consumer Electronics Control (CEC) capability allows HDMI devices to control each other when necessary and allows the user to operate multiple devices with on ...

Digital Visual Interface
Digital Visual Interface (DVI) is a video display interface developed by the Digital Display Working Group (DDWG). The digital interface is used to connect a video source, such as a video display controller, to a display device, such as a computer monitor. It was developed with the intention of creating an industry standard for the transfer of digital video content. This interface is designed to transmit uncompressed digital video and can be configured to support multiple modes such as DVI-A (analog only), DVI-D (digital only) or DVI-I (digital and analog). Featuring support for analog connections, the DVI specification is compatible with the VGA interface. This compatibility, along with other advantages, led to its widespread acceptance over competing digital display standards Plug and Display (P&D) and Digital Flat Panel (DFP). Although DVI is predominantly associated with computers, it is sometimes used in other consumer electronics such as television sets and DVD play ...

High-bandwidth Digital Content Protection
High-bandwidth Digital Content Protection (HDCP) is a form of digital copy protection developed by Intel Corporation to prevent copying of digital audio and video content as it travels across connections. Types of connections include DisplayPort (DP), Digital Visual Interface (DVI), and High-Definition Multimedia Interface (HDMI), as well as less popular or now deprecated protocols like Gigabit Video Interface (GVIF) and Unified Display Interface (UDI). The system is meant to stop HDCP-encrypted content from being played on unauthorized devices or devices which have been modified to copy HDCP content. Before sending data, a transmitting device checks that the receiver is authorized to receive it. If so, the transmitter encrypts the data to prevent eavesdropping as it flows to the receiver. In order to make a device that plays HDCP-enabled content, the manufacturer must obtain a license for the patent from Intel subsidiary Digital Content Protection LLC, pay an annual fee, and sub ...

Digital Transmission Content Protection
Digital Transmission Content Protection (DTCP) is a digital rights management (DRM) technology that restricts digital home technologies including DVD players and televisions by encrypting interconnections between devices. This permits the distribution of content through other devices such as personal computers or portable media players, if they also implement the DTCP standards. DTCP has also been referred to as "5C" content protection, a reference to the five companies that created DTCP; Hitachi, Intel, Matsushita, Sony, and Toshiba. The standard was originally proposed in February 1998, when the five companies presented the system to the Copy Protection Technical Working Group (CPTWG), an ''ad hoc'' body organized to evaluate DRM technologies. The five companies subsequently established thDigital Transmission Licensing Administrator(DTLA) in June 1998 to simplify licensing procedures and promote acceptance of the DTCP method by content providers, electronics manufacturers, and br ...
