IEC 62455
IEC 62455 (also known as the 18Crypt system) is an International Electrotechnical Commission terminal specification standard, prepared by the IEC 100 (Audio, video and multimedia systems and equipment) Technical Committee (TC), for a service purchase and protection system for digital broadcasts. Its full title is Internet protocol (IP) and transport stream (TS) based service access. This 18Crypt technology aimed to compete the Open Security Framework (OSF) has never been successful in the market where less than 10 000 deployed devices were using it. On the opposite, the OSF aimed as an open approach enabling wider competition has been widely deployed in millions of devices and re-used in many standards like in the USA (MediaFlo, ATSC-MH) or in China. Scope The specification includes service purchase and protection functions, and applies to: * IPDC over DVB-H systems * DVB T/C/S systems * MPEG2 TS-based IP systems * Non-MPEG2 TS-based IP systems Editions Version 1 of the standard wa ...

International Electrotechnical Commission
The International Electrotechnical Commission (IEC; in French: ''Commission électrotechnique internationale'') is an international standards organization that prepares and publishes international standards for all electrical, electronic and related technologies – collectively known as " electrotechnology". IEC standards cover a vast range of technologies from power generation, transmission and distribution to home appliances and office equipment, semiconductors, fibre optics, batteries, solar energy, nanotechnology and marine energy as well as many others. The IEC also manages four global conformity assessment systems that certify whether equipment, system or components conform to its international standards. All electrotechnologies are covered by IEC Standards, including energy production and distribution, electronics, magnetics and electromagnetics, electroacoustics, multimedia, telecommunication and medical technology, as well as associated general disciplines such ...

Digital Video Broadcasting
Digital Video Broadcasting (DVB) is a set of international open standards for digital television. DVB standards are maintained by the DVB Project, an international industry consortium, and are published by a Joint Technical Committee (JTC) of the European Telecommunications Standards Institute (ETSI), European Committee for Electrotechnical Standardization (CENELEC) and European Broadcasting Union (EBU). Transmission DVB systems distribute data using a variety of approaches, including: * Satellite: DVB-S, DVB-S2, and DVB-SH ** DVB-SMATV for distribution via SMATV * Cable: DVB-C, DVB-C2 * Terrestrial television: DVB-T, DVB-T2 ** Digital terrestrial television for handhelds: DVB-H, DVB-SH * Microwave: using DTT ( DVB-MT), the MMDS ( DVB-MC), and/or MVDS standards ( DVB-MS) These standards define the physical layer and data link layer of the distribution system. Devices interact with the physical layer via a synchronous parallel interface (SPI), synchronous ... [...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, ...
