Zusammenfassung:PCT No. PCT/FR81/00097 Sec. 371 Date Mar. 29, 1982 Sec. 102(e) Date Mar. 29, 1982 PCT Filed Aug. 7, 1981.This invention concerns an integrated interface circuit between a television receiver and its peritelevision connector, to allow the connection of an external source such as a magnetoscope. Said circuit comprises a video interface stage (EV), an audio interface stage (EA), and a switching stage (EC), which uses logic signals at its inputs (13, 12, 11) to switch, or not switch, on the one hand a selector switch (I1) in the video stage, and on the other hand two selector switches (I2, I3) in the audio stage.
