Abstract

Un système multimédia (SM) comprend : - un amplificateur (A1) numérique et à au moins un canal et couplé à une première interface de réseau (I1) via un premier émetteur/récepteur (ER1) esclave, - au moins un organe audio (O1-O3) alimenté en signaux audio amplifiés par, ou alimentant en signaux audio à amplifier, un canal de l’amplificateur (A1), - un boîtier multimédia (BM) comportant au moins un processeur de traitement de signal (PT), couplé à une seconde interface de réseau (I2) via un second émetteur/récepteur (ER2) maître, et assurant un traitement programmé de chaque signal destiné à, ou provenant de, chaque canal de l’amplificateur (A1), et - un réseau audio (RA) numérique, haut débit et auquel sont connectées les première (I1) et seconde (I2) interfaces de réseau. Figure à publier avec l’abrégé : Fig. 1A multimedia system (SM) comprises: - a digital amplifier (A1) with at least one channel and coupled to a first network interface (I1) via a first slave transmitter / receiver (ER1), - at least one audio device ( O1-O3) supplied with audio signals amplified by, or supplied with audio signals to be amplified, a channel of the amplifier (A1), - a multimedia box (BM) comprising at least one signal processing processor (PT), coupled to a second network interface (I2) via a second master transmitter / receiver (ER2), and ensuring programmed processing of each signal intended for, or coming from, each amplifier channel (A1), and - an audio network (RA) digital, high speed and to which the first (I1) and second (I2) network interfaces are connected. Figure to be published with the abstract: Fig. 1
