Role Of Scart

SCART is French originated standard and associated 21-pin connector for connecting audio-visual (AV) equipment together. It is from the Radio and Television Receiver Manufactures’ Association. The SCART system was intended to simplify connecting audio-video equipment (including TV’s, VCR’s, DVD players and game consoles). To achieve this it gathered all of the analogue signal connections into a single cable with a unique connector that made incorrect nearly impossible. There are so many disadvantages of SCART.

Let some be mentioned here. SCART cannot carry both s-video and RGB signals at the same time. It is, however, possible to output S-Video and RGB alternately, and the TV set will adapt automatically if it understands SCART’s S-Video extension. As the technology developed in present, the SCART cable have been disappear from the market, because modern devices systematically provide RGB signals. The SCART cables provide only limited locking, using detents. Cheap 10-pin SCART connectors can be very fragile and phone to breaking or losing pins, since they are big and hallow. 21-pin connectors are generally stronger. These show the disadvantages of SCART.

When we see the SCART cables ,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 the cable connects to an input signal at the other end.
