(EN) AUDIO PLAYBACK SYSTEM MONITORING
(FR) MONITORING DE SYSTÈME DE LECTURE AUDIO
Abstract
(EN) In some embodiments, a method for monitoring speakers within an audio playback system (e.g., movie theater) environment. In typical embodiments, the monitoring method assumes that initial characteristics of the speakers (e.g., a room response for each of the speakers) have been determined at an initial time, and relies on one or more microphones positioned in the environment to perform a status check on each of the speakers to identify whether a change to at least one characteristic of any of the speakers has occurred since the initial time. In other embodiments, the method processes data indicative of output of a microphone to monitor audience reaction to an audiovisual program. Other aspects include a system configured (e.g., programmed) to perform any embodiment of the inventive method, and a computer readable medium (e.g., a disc) which stores code for implementing any embodiment of the inventive method.
(FR) Dans certains modes de réalisation, l'invention concerne un procédé destiné à commander des haut-parleurs dans un environnement à système de lecture audio (par ex., un cinéma). Dans des modes de réalisation typiques, le procédé de commande suppose que les caractéristiques initiales des haut-parleurs (par ex., une réponse de la pièce pour chaque haut-parleur) ont été déterminées à un moment initial, et repose sur un ou plusieurs microphones positionnés dans l'environnement destiné à réaliser une vérification d'état sur chaque haut-parleur afin d'identifier un changement d'au moins une caractéristique d'un des haut-parleurs a eu lieu depuis le moment initial. Dans d'autres modes de réalisation, le procédé traite des données indicatives de sortie d'un microphone pour surveiller la réaction de l'audience à un programme audiovisuel. D'autres aspects comprennent un système conçu (par ex., programmé) pour mettre en œuvre n'importe quel mode de réalisation du procédé de l'invention, et un support lisible par ordinateur (par ex., un disque) qui stocke un code pour mettre en œuvre n'importe quel mode de réalisation du procédé de l'invention.
