Abstract

Abstract Device for indicating which, among the N sources connected to the N inputs (E1-EN) respectively of a switching matrix (1), is received on a given output (Si) of the matrix. The device comprises a decoding circuit (5) for determining, on the basis of the matrix-control signals, which matrix input, and therefore which source, is switched onto the given output (Si) by the matrix. The decoding circuit furnishes N separate signals relating respectively to the N connections between the given output and the N inputs. Each of these N signals is used to display a text (X5TV) on a screen (12), designating the source received by the given output. Application to the identification of any source received through a switching matrix. <IMAGE>
