Antenne 2
France 2 () is a French public national television channel. It is part of the state-owned France Télévisions group, along with France 3, France 4 and France 5. France Télévisions also participates in Arte and Euronews. Since 3:20 CET on 7 April 2008, all France 2 programming has been broadcast in 16:9 widescreen format over the French analogue and digital terrestrial television. An HD simulcast feed of France 2 has been broadcasting on satellite provider CanalSat since 1 July 2008 and on digital terrestrial television since 30 October 2008. History Originally under the ownership of the RTF, the channel went on the air for the first time on 18 April 1964 as '' RTF Télévision 2''. Within a year, ORTF rebranded that channel as ''La deuxième chaîne'' (The Second Channel). Originally, the network was broadcast on 625-line transmitters only in preparation for the discontinuation of 819-line black & white transmissions and the introduction of colour. The switch to colour occu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1080i
1080i (also known as Full HD or BT.709) is a combination of frame resolution and scan type. 1080i is used in high-definition television (HDTV) and high-definition video. The number "1080" refers to the number of horizontal lines on the screen. The "i" is an abbreviation for "interlaced"; this indicates that only the even lines, then the odd lines of each frame (each image called a video field) are drawn alternately, so that only half the number of actual image frames are used to produce video. A related display resolution is 1080p, which also has 1080 lines of resolution; the "p" refers to progressive scan, which indicates that the lines of resolution for each frame are "drawn" on the screen in sequence. The term assumes a widescreen aspect ratio of 16:9 (a rectangular TV that is wider than it is tall), so the 1080 lines of vertical resolution implies 1920 columns of horizontal resolution, or 1920 pixels × 1080 lines. A 1920 pixels × 1080 lines screen has a total of 2.1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DStv
Digital Satellite Television, commonly abbreviated to DStv, is a Sub-Saharan African direct broadcast satellite service owned by MultiChoice and based in Randburg, South Africa. Launched on 6 October 1995, the service provides multiple audio, radio and television channels and services to subscribers, mostly in South Africa and Nigeria. DStv formerly had operations in Thailand under United Broadcasting Corporation (UBC), which is now TrueVisions. History In 1986, pay-television came to South Africa when a single-channel analogue service, M-Net, was launched by Naspers and local businesses/companies. For almost seven years, all of M-Net's operations were handled by a single dedicated company until 1995 when a second subsidiary company, MultiChoice, was launched. This company would take over the operations of M-Net including decoder sales, subscriber services (which were also available in local shops) and account management. MultiChoice would also embark on establishing presence i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

NICAM
Near Instantaneous Companded Audio Multiplex (NICAM) is an early form of lossy compression for digital audio. It was originally developed in the early 1970s for point-to-point links within broadcasting networks.Croll, M.G., Osborne, D.W. and Spicer, C.R. (1974), ''Digital sound signals: the present BBC distribution system and a proposal for bit-rate reduction by digital companding''. IEE Conference publication No. 119, pp. 90–96 In the 1980s, broadcasters began to use NICAM compression for transmissions of stereo TV sound to the public. History Near-instantaneous companding The idea was first described in 1964. In this, the 'ranging' was to be applied to the analogue signal before the analogue-to-digital converter (ADC) and after the digital-to-analogue converter (DAC). The application of this to broadcasting, in which the companding was to be done entirely digitally after the ADC and before the DAC, was described in a 1972 BBC Research Report. Point-to-point links NI ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SECAM
SECAM, also written SÉCAM (, ''Séquentiel de couleur à mémoire'', French for ''color sequential with memory''), is an analog color television system that was used in France, some parts of Europe and Africa, and Russia. It was one of three major analog color television standards, the others being PAL and NTSC. This page primarily discusses the SECAM colour encoding system. The articles on broadcast television systems and analog television further describe frame rates, image resolution, and audio modulation. SECAM video is composite video because the luminance (luma, monochrome image) and chrominance (chroma, color applied to the monochrome image) are transmitted together as one signal. All the countries using SECAM are currently in the process of conversion, or have already converted to Digital Video Broadcasting (DVB), the new pan-European standard for digital television. SECAM remained a major standard into the 2000s. History Development of SECAM predates PAL, and be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central European Time
Central European Time (CET) is a standard time which is 1 hour ahead of Coordinated Universal Time (UTC). The time offset from UTC can be written as UTC+01:00. It is used in most parts of Europe and in a few North African countries. CET is also known as Middle European Time (MET, German: MEZ) and by colloquial names such as Amsterdam Time, Berlin Time, Brussels Time, Madrid Time, Paris Time, Rome Time, Warsaw Time or even Romance Standard Time (RST). The 15th meridian east is the central axis for UTC+01:00 in the world system of time zones. As of 2011, all member states of the European Union observe summer time (daylight saving time), from the last Sunday in March to the last Sunday in October. States within the CET area switch to Central European Summer Time (CEST, UTC+02:00) for the summer. In Africa, UTC+01:00 is called West Africa Time (WAT), where it is used by several countries, year round. Algeria, Morocco, and Tunisia also refer to it as ''Central European ...

Analog High-definition Television System
Analog high-definition television has referred to a variety of analog video broadcast television systems with various display resolutions throughout history. Pre-1940 On 2 November 1936 the BBC began transmitting the world's first public regular analog "high definition" television service from the Victorian Alexandra Palace in north London. It therefore claims to be the birthplace of television broadcasting as we know it today. The UK's 405-line system introduced in 1936 was described as "high definition"; however, this was in comparison with the early 30-line (largely) experimental system from the 1920s, and would not be considered high definition by modern standards. John Logie Baird, Philo T. Farnsworth, and Vladimir Zworykin had each developed competing TV systems, but resolution was not the issue that separated their substantially different technologies, it was patent interference lawsuits and deployment issues given the tumultuous financial climate of the late 1920s ...

Office De Radiodiffusion Télévision Française
L'Office de Radiodiffusion-Télévision Française (ORTF; ) was the national agency charged, between 1964 and 1975, with providing public radio and television in France. All programming, and especially news broadcasts, were under strict control of the national government. History Background In 1945, the provisional French government established a public monopoly on broadcasting with the formation of Radiodiffusion Française (RDF). This nationalisation of all private radio stations marked the beginning of a new era of state-controlled broadcasting in France. As part of its mandate, the RDF also established a 441-line television station known as ''Télévision française''. This station made use of the frequencies previously utilised by the Nazi-operated ''Fernsehsender Paris''. In 1949, the RDF underwent a name change to Radiodiffusion-Télévision Française (RTF) in order to reflect the organisation's growing focus on television broadcasting. By the end of the year, t ...
