96-474: A 'ghosting' effect, but it does not always eliminate it due to various factors. A more permanent method is to remove pin 19 (Video Out) from the SCART plug that is put into the TV, preventing a signal from being broadcast by the TV into the cable, so it cannot cross-talk with the incoming signal. Two pins provide switching signals. Pin 8, the switch signal pin, carries a DC voltage from the source that indicates

However, this protocol was rarely used, as it was limited only to a certain manufacturer, and the connections were different from a manufacturer to another, and in some cases, it was only commanded by the pin 8. In this case, it was unusable with RCA to SCART adapters. Also, if a Compatible TV with such connection and

240-624: A Japanese version of the SCART connector, which is referred to as the Japanese RGB-21 connector, EIAJ TTC-003, or simply JP-21. This version of SCART uses similar signals and the same connector, but it has a different pinout. In Japan and Korea, it is commonly called RGB-21 while it is more generally called JP-21 in the English-speaking world. JP-21 was standardised in January 1983 with the norm TTC-0003 published by EIAJ , which
288-460: A Pay TV decoder and a dish positioner/polariser to a single Decoder socket on the receiver. CENELEC EN 50157-1 introduced AV.link as a standardised protocol to carry advanced control information between devices. It is a single-wire serial data bus and allows carrying remote control information and to negotiate analogue signal types (e.g. RGB). AV.link is also known as nexTViewLink or trade names such as SmartLink, Q-Link or EasyLink. It appears as
336-517: A SCART set-top box does not have to process and send back a complete new video signal, which would require full decoding and re-encoding of the color information, a signal-degrading and costly process, especially given the presence of different standards in Europe. The box can instead ask the TV to stop displaying the normal signal and display a signal it generates internally for selected image areas, with pixel -level granularity. This can also be driven by
384-490: A compatible DVD with such connection, but from different manufacturers were interconnected, the surround might not work, and only the stereo sound from the DVD player was available to the TV, because some manufacturers did not use SPDIF, but an own protocol. Also, this connection might be also lost, if the connection of the DVD with the TV was made indirectly (through a VCR in daisy chaining mode, for example), however, some VCR allowed
432-401: A composite sync, which is SCART-compatible. Besides simple connection of external devices to SCART TVs, RGB SCART is used in the retrogaming scene for connecting vintage games consoles (including ones internally modified for RGB or 60 Hz RGB where necessary) to: The SAM Coupé microcomputer also uses a SCART connector for its output, however it is a non-standard pinout. There is also
480-432: A composite video signal through a German-originated DIN-style connector , an American-originated RCA connector , an SO239 connector or a BNC connector . The SCART connector first appeared on TVs in 1977. It became compulsory on new TVs sold in France from January 1980, and since 1987 in eastern Europe, such as Poland. The actual French legal decree was adopted on 7 February 1980 and revoked on 3 July 2015. The standard
528-499: A digital satellite platform, with 24 channels and interactive services. On 23 May 2005, CanalSatellite was renamed Canalsat. With Canal+, the utilisation of the card pairing (QEV) technology allowed access to many channels such as Eurosport , Paris Premiere , or LCI . On 31 August 2006, after acquiring competitor TPS , the two companies were merged within the Canal+ Group. On 7 December 2010 both Canal+ channels and

#1732772351446576-512: A recorder. Closing a loop on either the "up" or "down" chain-path may not have useful effects and may create instability. As audio and (composite) video use the same pins on "down" and "up" connectors (and require a crosslinked cable), it is also possible to connect two devices directly to each other without paying attention to the type of the socket. However, this no longer works when S-Video signals are used. As straight links (RGB red and blue up) were re-purposed to carry chrominance information,
624-410: A standard format as a result. Some sources assume that the TV is always capable of widescreen functionality and hence never perform the adaptations. Some sources will not even issue the widescreen signal or maintain it at the same level all the time. Other sources might offer the option of truncating the sides, but not of letterboxing, which requires significantly more processing. Notably, the circuitry of
672-418: A virtually unlimited number of devices to a single SCART socket on the TV. While audio and video signals can travel both "up" to the TV and "down" to devices farther away from the TV, this is not true for RGB (and non-standard YP B P R ) signals, which can only travel towards the TV. "Down" and "up" are conventional. Logically, the TV is the last device of the "up" chain-path (stream) and the first device in
720-472: Is CENELEC document number EN 50049–1. SCART is sometimes referred to as the IEC 933-1 standard. Before SCART was introduced, TVs did not offer a standardised way of inputting signals other than RF antenna connectors, and these differed between countries. Assuming other connectors even existed, devices made by various companies could have different and incompatible standards. For example, a domestic VCR could output
768-467: Is induced or crosstalked onto an incoming video signal due to inadequate or non-existent screening; the result is ghostly images or shimmering superimposed on the incoming signal. To non-destructively verify if a SCART cable uses coaxial cables, unscrew the strain relief at the SCART connector and fold open the plastic shell. Using higher-quality cables such as those with ribbon cords that have properly shielded coaxial cables inside might help in reducing
816-570: Is no switching signal to indicate S-Video. Some TVs can auto-detect the presence of the S-Video signal but more commonly the S-Video input needs to be manually selected. The same for the rare component YPbPr, which is in many cases implemented over a composite or RGB SCART. The use of the data pins was not standardised in the original SCART specification, resulting in the use of several different protocols, both proprietary protocols and semi-proprietary protocols based on standards such as D²B . Some of

The shareholders were Canal+ (66 percent) and Lagardère Active (34 percent), a subsidiary of Lagardère . Canal+ began satellite broadcasting in 1992, to reach parts of France not covered by cable. On 27 April 1996, CanalSatellite launched as

The data pins, 10, 12, 14, were used by some manufacturers for Dolby Pro Logic , surround and multichannel on their TV sets (some high end models with built in Dolby decoders, and external surround speakers, both CRT, LCD and plasma sets, and only in Europe - and European versions of Japanese TV Sets and DVD players -, and mainly on S/PDIF), in order to connect
960-405: The "down" chain path. Physically, the TV is under the device which sits on its top, hence the name "set-top box" for the device. Moreover, some sockets' relative position may enforce the belief that the TV is physically the last in the down direction. Logically, the TV is on top and ends the "up" chain-path, translating the electrical info into an image and sound. From the same logical point of view
1008-533: The 90 CanalSat channels became available live on Microsoft's XBOX 360 . In 2011 the merger with TPS was cancelled by the Competition Authority. Canal+ appealed, and the Authority determined that its authorisation would be conditional on a number of injunctions, including "re-establish[ing] sufficient competition in the pay television market". In September 2015 Vincent Bolloré announced that

#17327723514461056-889: The Nintendo GameCube and Xbox automatically switch to the proper mode, the PlayStation 2 must be told via a selection in the system menu whether it is to use YP B P R or RGB video. RGB is only available on PAL region GameCube and Wii consoles, while S-Video is only available on NTSC consoles. Some older consoles such as the Master System , Mega Drive/Genesis , and Super Nintendo Entertainment System output RGB, and many older home computers ( Amstrad CPC , later ZX Spectrum models, MSX , Amiga , Atari ST , BBC Micro and Acorn Archimedes , etc.) output RGB with composite sync suitable for SCART use, via DIN plugs. Standard-resolution arcade monitors use RGB signals with
1104-512: The S-Video pinouts are different for "down" and "up" SCART connectors. Further, they are often not fully implemented. Paying attention to the type of socket is essential when handling component RGB/YP B P R /S-video. Damage can be caused to devices incorrectly connected as follows: Damaging pins 7, 11 or 15 may result in yellow, purple or blue/green images, due to the missing blue, green or red components respectively. When using S-video, damaging pin 7 or 15 may result in black-white images due to
1152-426: The SCART connector will be held at approximately half mains voltage if it is plugged into a powered TV with the other end unplugged. If the cable is then plugged into an earthed device with a metal case, inadvertent contact with the SCART cable shield while the earthed device is touched with the other hand can cause a painful electric shock. For this reason the device end of the cable should always be plugged in first and
1200-415: The TV end plugged in last. Quality differences exist in SCART cables. While a proper SCART cable uses miniature coaxial cables for the video signals, cheap SCART cables often use plain wires for all signals, resulting in a loss of image quality and greatly reducing the maximum cable length. A common problem on a cheap SCART cable is that a TV outputs a composite video signal from its internal tuner and this
1248-462: The TV to power off, which it will do if it had been powered on by the VCR's request and if it remained in video mode. Only some TVs will do this—most only implement automatic switching to and from the SCART input. The same signal can be used by a satellite receiver or set-top box to signal a VCR that it is supposed to start and stop recording ("pin 8 recording"). This configuration usually requires that

The name SCART comes from Syndicat des Constructeurs d'Appareils Radiorécepteurs et Téléviseurs , "Radio and Television Receiver Manufacturers' Association", the French organisation that created the connector in the mid-1970s. The related European standard EN 50049
1344-407: The VCR be farther from the TV than the source, so the signal usually travels "down". SCART also supports automatic widescreen switching . This is an extension of the functionality of pin 8, which previously only indicated to the TV that an external signal should be displayed. Ideally, a widescreen source should offer three operating modes in order to deal with widescreen signals: In the first case,
1392-441: The appropriate AV channel when the SCART attached device is switched on. SCART was also used for high definition signals such as 720p , 1080i, 1080p with YPbPr connection by some manufacturers, but this usage is scarce due to the advent of HDMI . In Europe, SCART was the most common method of connecting AV equipment and was a standard connector for such devices; it was far less common elsewhere. The official standard for SCART
1440-463: The cable connects to an input signal at the other end. The complete list of wires that are swapped are: pins 1 and 2, pins 3 and 6, pins 17 and 18, pins 19 and 20. The original SCART specification provided for different cable (cordset) types denoted by a key color, but color-coding is rarely used and cables often use different, non-standard configurations. Maximum SCART cable length is estimated to be about 10 to 15 metres without amplification. Due to

It was originally developed by Philips in the 1980s. In 2006 it has been withdrawn by IEC because another standard was proposed, JTC1 SC 83/WG1. There remain many IEC61030-compliant devices, such as some Philips-branded head units and CD changers from car stereos. The SCART connector provides

The limitations apply mostly to satellite TVs, while DVD players can always at least letterbox and often zoom . The cables for connecting equipment together have a male plug at each end. Some of the wires such as ground, data, switching and RGB connect to the identical pin number at each end. Others such as audio and video are swapped so that an output signal at one end of
1584-447: The info stream, wherever it originates, may need processing such as decrypting (decoding, descrambling) or adding captioning/subtitles. In this case the info stream is sent logically "down" to dedicated function devices. From the last processing device the info stream is sent logically "up" to the TV, through all the chain-path. Another case is when the info stream is sent "down" and not expected to be sent back "up", for example when sent to

The GameCube , Wii , Neo-Geo , Dreamcast , PlayStation , PlayStation 2 , PlayStation 3 , Xbox and Xbox 360 can output RGB , component video , S-Video, or composite video. These consoles come with the standard composite video connector, but the manufacturers and third parties sell connectors for component video hookup and for RGB SCART hookup. Where
1680-453: The missing chroma component ("down" and "up" respectively). Similarly, damaging pins 7 and 15 (P B and P R ) while leaving pin 11 (Y) undamaged may result in black-white images when using YP B P R . Damaging more than one of these pins may result in combined effects. SCART enables a device to command the TV to very quickly switch between signals, in order to create overlays in the image. In order to implement captioning or subtitles ,
1728-466: The most creative usages appeared in analogue satellite receivers. The function of decoding hybrid, time-compressed analogue-digital MAC transmissions into RGB and analogue audio was akin to making a digital receiver out of an analogue one. The D²B pins (10 and 12) were used for communicating with satellite dish positioners and for driving magnetic polarisers , before these became incorporated into LNBs . The daisy-chaining features were used to connect both
1776-698: The pass-through of these signals. Some DVD player manufacturers on some models offered SPDIF only on SCART, and an adapter in order to extract the digital audio signal to send it to a home cinema. To the present day this connection remains rare, as HDMI, S/PDIF, and TOSLINK can provide multichannel audio, also some TV sets with Surround built in may have an Optical or S/PDIF INPUT, beside Output . Nearly all modern DVD players and set-top boxes with SCART sockets can output RGB signal, which offers superior picture quality to composite signal. However, many devices do not have RGB output turned on by default, instead defaulting to composite video: RGB often has to be set up manually in
1824-400: The relatively high signal voltages used in SCART, "hot plugging" (connecting or disconnecting devices while they are on) is not recommended. Although there is no risk of personal injury, there is the possibility of damaging electronics within the devices if the connector is inserted improperly. Also, since many TVs are Class II (double-insulated) rather than earthed, the large exposed shield on
1872-440: The service would change its name to simply "Canal". CanalSat adopted the new name on 15 November 2016, accompanied by new offerings, merging with the bouquet Les Chaînes Canal+ . In 2017, Canal lost Discovery and NBCUniversal channels, recovered by SFR . Canal replaced them by exclusive newly-launched channels: Warner TV , Polar+, and Novelas TV. The service was renamed Canal+ on 1 August 2019, unifying its brand across
1920-605: The signals from the TV to the set-top decoder and send the processed result back to the TV. When a scrambled show is recorded, the VCR will drive the set-top box from its own tuner and send the unscrambled signals to the TV for viewing or simple recording control. Alternatively, the VCR could use the signals from the TV, in which case it would be inadvisable to change channels on the TV during the recording. The "down" socket can also be used to connect other devices, such as DVD players or game consoles. As long as all devices have at least one "down" and "up" socket, this allows for connecting
1968-508: The time and watch for returned signals, to display and reproduce them. This allows "transparent" set-top boxes, without any tuner, which just "hook" and pre-process the TV signals. This feature is used for analogue pay TV like Canal Plus and was used for decoding teletext . A VCR will often have two SCART sockets, to connect it to the TV ("up", "primary" or "1"), and for video input from a set-top box or other device ("down", "secondary" or "2"). When idle or powered off, VCRs will usually forward

2016-454: The type of video present. Pin 16, the blanking signal pin, carries a signal from the source that indicates that the signal is either RGB or composite. The original specification defined pin 16 as a high frequency (up to 3 MHz) signal that blanked the composite video. The RGB inputs were always active and the signal 'punches holes' in the composite video. This could be used to overlay subtitles from an external Teletext decoder. There
2064-456: The use of a "transparent" color in a teletext page. SCART allows a connected device to bring it in and out of standby mode or to switch it to the AV channel. A VCR or other playback device will optimally power on when a cassette is inserted, power on the TV (or switch it to video mode) and then start playing immediately if the cassette write protection tab is absent. When turned off, the VCR will ask
2112-403: The widescreen pin allows to indicate the current signal format, which allows widescreen TVs to adjust the image width, and widescreen-capable standard TVs to compress the scan lines of the image vertically to a letterbox shape portion of the picture tube. In the second case, the widescreen SCART signal is never active and the signal source performs the adaptations itself so that the image has always
2160-411: Was extended at the end of the 1980s to support the new S-Video signals. A TV can be awakened from standby mode, and it can automatically switch to appropriate AV channel, when the device attached to it through a SCART connector is turned on. SCART is bi-directional regarding standard composite video and analogue audio. A TV will typically send the antenna audio and video signals to the SCART sockets all
2208-451: Was refined and published in 1978 by CENELEC , calling it péritelevision , but it is commonly called by the abbreviation péritel in French. The signals carried by SCART include both composite and RGB (with composite synchronisation) video , stereo audio input/output and digital signalling. SCART is also capable of carrying S-Video signals, using the red pins for chroma. A TV can be woken from standby mode and automatically switch to
2256-625: Was subject to several amendments and at least 2 major revisions, approved by CENELEC on 13 November 1988 (EN 50049-1:1989) and 1 July 1997 (EN 50049-1:1997). The SCART system was intended to simplify connecting AV equipment (including TVs, VCRs , DVD players and games consoles ). To achieve this it gathered all of the analogue signal connections into a single cable with a unique connector, which normally made incorrect connections nearly impossible. The signals carried by SCART include both composite and RGB (with composite synchronisation) video, stereo audio input/output and digital signalling. The standard
2304-567: Was superseded in March 1993 by the norm CPR-1201 to include S-Video. CPR-1201 was withdrawn in March 2003 to be replaced by the equivalent norm CPR-1205, representing Japan's transition from analogue to digital, and thus antiquating analogue connectors. It was adopted in Japan for the connector's ability to support RGB output format (no compression nor deterioration of original video signals) but, contrary to SCART in Europe, it never saw widespread use on
