Συνδεσμολογία SCART
The Scart (Syndicat des Constructeurs d'Appareils Radiorιcepteurs et
Tιlιviseurs) connector is used for combined audio and video connections. The
connector is also known as Pertitel connector or Euroconnector. A formal
description is given in the CENELEC EN 50 049-1:1989 standard or in the IEC
933-1 standard. Different pin-configurations exist. Which confirations are
available depends on the video device used. Sometimes one can choose the
configuration (like composite or S-video) by changing a software setting. Two
status signals define (partly) which video signals are active. A video device
can use these status signals to automatically switch between internal or
external audio/video signals.

EasyLink enables bi-directional communication between a television set and a
video recorder. This way a video recorder can, for example, copy the channel
settings of the television set. Who knows the details?
