Centre Commun D'études De Télévision Et Télécommunications
CCETT or Centre commun d'études de télévision et télécommunications (''Centre for the Study of Television broadcasting and Telecommunication'' or ''Common Study Center of Telediffusion and Telecommunication'') was a research centre created in Rennes (France) in 1972 jointly by the Office de Radiodiffusion Télévision Française (ORTF) (later Télédiffusion de France) and Centre National d'Etudes des Telecommunications (CNET) (Direction Générale des Télécommunications, part of the French Ministry of Posts and Telecommunications) for development of new techniques for processing, transmission and distribution of audiovisual signals. CCETT became part of France Télécom R&D, the research and development division of France Télécom in 1998. This division was derived from different ancient entities, such as CNET (the research and development centre of France Telecom, created in 1944), the CCETT, as well as other entities. Since 2007, France Telecom R&D is also known as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

History Of Rennes
Rennes, France, is the administrative capital of the French department of Ille-et-Vilaine. Before the French Revolution, prior to the integration of the Duchy of Brittany into the Kingdom of France, Rennes was the capital of the duchy, with the other historical capitals of Brittany's Ducal period being Nantes and Vannes. It has a long history due to its location at the confluence of two rivers and its proximity to the bordering regions from which arose various challenges to the borders of Brittany. Earliest history By the 2nd century BC the Gallic tribe known as the Riedones had occupied a territory in eastern Brittany roughly equivalent to the modern department of Ille-et-Vilaine and had established their chief township at the confluence of the Ille and Vilaine rivers, the site of the modern city of Rennes. Although the tribe's name - from the Celtic root ''red'' cognate with ''ride'' suggesting the Riedones were known for their horsemanship - would eventually default to thei ...

History Of Telecommunications In France
History is the systematic study of the past, focusing primarily on the human past. As an academic discipline, it analyses and interprets evidence to construct narratives about what happened and explain why it happened. Some theorists categorize history as a social science, while others see it as part of the humanities or consider it a hybrid discipline. Similar debates surround the purpose of history—for example, whether its main aim is theoretical, to uncover the truth, or practical, to learn lessons from the past. In a more general sense, the term ''history'' refers not to an academic field but to the past itself, times in the past, or to individual texts about the past. Historical research relies on primary and secondary sources to reconstruct past events and validate interpretations. Source criticism is used to evaluate these sources, assessing their authenticity, content, and reliability. Historians strive to integrate the perspectives of several sources to develop a ...

Antiope (teletext)
Antiope was a French teletext standard in the 1980s. It also formed the basis for the display standard used in the French videotex service Minitel. The term allegedly stood for ''Acquisition Numérique et Télévisualisation d’Images Organisées en Pages d’Écriture'', which could be loosely translated as ''Digital Acquisition and Remote Visualization of Images Organized into Written Pages''. History Work on Antiope started in 1972 at CCETT, the newly merged French national research centre for television and telecommunications in Rennes, with first field trials in 1975. The system was officially launched in 1976 at Vidcom in Cannes, and simultaneously at the СПОРТ 76 exposition in Moscow. It was adopted into the international standard CCIR 653 (now ITU-R BT.653) of 1986 as CCIR Teletext System A. Commercial broadcasting of Antiope began on Antenne 2 in 1979. To publicise the service, pages were even transmitted ''en clair'' instead of the test card (compare the BBC ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

MPEG Audio Layer II
MP2 (formally MPEG-1 Audio Layer II or MPEG-2 Audio Layer II, sometimes incorrectly called Musicam) is a lossy data compression, lossy audio compression format. It is standardised as one of the three audio codecs of MPEG-1 alongside MPEG-1 Audio Layer I (MP1) and MPEG-1 Audio Layer III (MP3). The MP2 abbreviation is also used as a common Filename extension, file extension for files containing this type of audio data, or its extended variant MPEG-2 Audio Layer II. MPEG-1 Audio Layer II was developed by Philips, Centre commun d'études de télévision et télécommunications, CCETT and Institut für Rundfunktechnik, IRT as the MUSICAM algorithm, as part of the European-funded Digital Audio Broadcasting (DAB) project. Alongside its use on DAB broadcasts, the codec has been adopted as the standard audio format for Video CD and Super Video CD media, and also for HDV. On the other hand, MP3 (which was developed by a rival collaboration led by Fraunhofer Society called ASPEC) gained mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Digital Audio Broadcasting
Digital Audio Broadcasting (DAB) is a digital radio international standard, standard for broadcasting digital audio radio services in many countries around the world, defined, supported, marketed and promoted by the WorldDAB organisation. The standard is dominant in Europe and is also used in Australia, and in parts of Africa and as of 2025, countries using DAB/DMB, 55 countries are actively running DAB broadcasts as an alternative platform to analogue FM. DAB was the result of a European research project and first publicly rolled out in 1995, with consumer-grade DAB Radio receiver, receivers appearing at the start of this millennium. Initially it was expected in many countries that existing FM broadcasting, FM services would switch over to DAB, although the take-up of DAB has been much slower than expected. In 2023, Norway became the first country to have implemented a national FM radio switch-off, with others to follow in the next years, Switzerland and the United Kingdom ...

Moving Picture Experts Group
The Moving Picture Experts Group (MPEG) is an alliance of working groups established jointly by ISO and IEC that sets standards for media coding, including compression coding of audio, video, graphics, and genomic data; and transmission and file formats for various applications.John Watkinson, ''The MPEG Handbook'', p. 1 Together with JPEG, MPEG is organized under ISO/IEC JTC 1/ SC 29 – ''Coding of audio, picture, multimedia and hypermedia information'' (ISO/IEC Joint Technical Committee 1, Subcommittee 29). MPEG formats are used in various multimedia systems. The most well known older MPEG media formats typically use MPEG-1, MPEG-2, and MPEG-4 AVC media coding and MPEG-2 systems transport streams and program streams. Newer systems typically use the MPEG base media file format and dynamic streaming (a.k.a. MPEG-DASH). History MPEG was established in 1988 by the initiative of Dr. Hiroshi Yasuda ( NTT) and Dr. Leonardo Chiariglione ( CSELT). Chiariglione was th ...
