Title (EN) METHOD AND SYSTEM FOR TRANSMISSION PATH NOISE CONTROL
(FR) PROCÉDÉ ET SYSTÈME DE CONTRÔLE DE BRUIT DE TRAJET DE TRANSMISSION
Abstract:
(EN) A method for transmission path noise control using an audio headset (HS) and a sending device (SD) comprises generating microphone signals by a first and a second microphone (M1, M2, M2F) of the headset (HS) based on detected sound including desired audio information and noise. An encoded signal is generated on a first line (XL) of a data cable (C) by means of the headset (HS) by encoding input signals depending on the microphone signals. The method comprises transmitting the encoded signal from the headset (HS) to the sending device (SD) via the first line (XL), reconstructing the input signals by decoding the encoded signal by the sending device (SD), generating by the sending device (SD) a clean signal by applying a first noise control algorithm to the reconstructed first and second input signal and sending a signal depending on the clean signal to a communication network.
(FR) L'invention concerne un procédé de contrôle de bruit de trajet de transmission au moyen d'un casque audio (HS) et d'un dispositif d'envoi (SD). Le procédé comprend la génération de signaux de microphone par un premier et un second microphone (M1, M2, M2F) du casque (HS) sur la base d'un son détecté contenant des informations audio souhaitées et du bruit. Un signal codé est généré sur une première ligne (XL) d'un câble de données (C) au moyen du casque (HS) par encodage de signaux d'entrée dépendant des signaux de microphone. Le procédé consiste à : transmettre le signal encodé, du casque (HS) au dispositif d’envoi (SD), via la première ligne (XL) ; reconstruire les signaux d’entrée en décodant le signal codé par le dispositif d’envoi (SD) ; générer, par le dispositif d’envoi (SD), un signal propre , en appliquant un premier algorithme de contrôle de bruit sur les premier et second signaux d’entrée reconstruits ; et envoyer un signal dépendant du signal propre, à un réseau de communication.
