analog audio/video connection SCART ( or pƩritel) SCART refers to a coupling device and an audio/video connector that has been mainly used in Europe. It allows you to simply plug in peripherals (TV) that have analog audio/video functions using a 21-pin connector. There are three types of connectors : the plug on the devices, the male/male cord and the extension cord. SCART connectors are more often encountered (pƩritel) on equipment marketed in Europe. Today analogue television is being replaced by digital television; it allows access to high definition; SCART (pƩritel) which was therefore mandatory on televisions since 1980, is replaced by HDMI HDMI HDMI is a fully digital audio/video interface that transmits uncompressed encrypted streams. HDMI is used to connect an audio/video source (DVD player, Blu-ray player, computer or game console) to a high-definition TV. HDMI supports all video formats, including standard, improved, high-definition definition and multichannel sound. HDMI encapsulanses video data by TMDS. Initially, the maximum HDMI transmission tau w . The scart no longer exists since the end of 2014.
The SCART plug (pƩritel) has 21 pins and transmits analog signals. Cabling Pin 8 exploits the slow switching signal from the source, which switches the video input as well as the type of video signals to be used : - 0 V means "no signal", or internal signal (example : current operation of the TV); - +6 V means : selection of the auxiliary audio/video input and 16 : 9 aspect ratio (technical evolution after the original standard); - +12 V means : selection of auxiliary audio/video input and 4/3 format. Pin 16 is a signal from the source, which indicates whether the signal is RGB or composite : - 0 V to 0.4 V composite; - 1 V to 3 V (nominal 1 V peak) RGB only. Pin 16 is called fast switching : It can be used to embed the RGB signal within another video signal : Teletext and captioning. The video bandwidth allowed on fast switching is 6 MHz. 1 A-O-R RIGHT AUDIO OUTPUT 2 A-I-R RIGHT AUDIO INPUT 3 A-O-L LEFT AUDIO OUTPUT 4 A-GND GND AUDIO 5 B-GND BLUE - MASS 6 A-I-L AUDIO LEFT INPUT 7 B BLUE HD INPUT / OUTPUT 8 SWITCH SLOW SWITCHING (INPUT/EXTERNAL SOURCE) 9 GND GREEN 10 CLK-OUT ENTRANCE 11 GND GREEN HD INPUT/OUTPUT 12 DATA OUTPUT, INPUT/OUTPUT VERTICAL HD SYNCHRONIZATION 13 R GND RED / CHROMINANCE, MASS 14 DATA-GND MASS 15 R RED/ CHROMINANCE (YC), HD INPUT/OUTPUT 16 BLNK FAST SWITCHING 17 V-GND VIDEO / SYNCHRO / LUMINANCE, GROUND 18 EMPTY-GND GND VOID 19 V-OUT VIDEO / SYNCHRO / LUMINANCE OUTPUT 20 V-IN VIDEO / SYNCHRO / LUMINANCE INPUT 21 ARMORED COMMON GND ( SHIELDING )
The SCART plug is the most common on older TVs Limitations of the SCART socket (pĆ©ritel) The use of this plug is only of interest for screens that can be satisfied with a low definition (about 800 Ć 600). For higher definition displays, it is useful for connecting all products without an HDMI HDMI HDMI is a fully digital audio/video interface that transmits uncompressed encrypted streams.

Initially, the maximum HDMI transmission tau w output (DVD player, game console with disc player, digital receiver), because the connection by SCART (pĆ©ritel) leads to losses : Beyond three meters, an extender cord cannot effectively convey the weak and multiple analog signals it operates without disturbances occurring. Without specific treatment (video amplifier, audio filter) therefore non-compliance with the original standard, longer links are not recommended.
