Title
(EN) Audio playback system monitoring
(ZH) 音频回放系统监视
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.

在一些实施例中,一种用于监视音频回放系统(例如,电影院)环境内的扬声器的方法。在典型的实施例中,监视方法假设扬声器的初始特性(例如,对于每个扬声器的房间响应)已经在初始时间被确定,并且依赖于被定位在该环境中的一个或多个麦克风来对每个扬声器执行状态检查以识别这些扬声器中的任何一个的至少一种特性自从初始时间以后是否发生变化。在其他实施例中,所述方法生成指示麦克风的输出的数据以监视观众对视听节目的反应。其他方面包括一种被配置为(例如,被编程为)执行本发明的方法的任何实施例的系统、以及存储用于实现本发明的方法的任何实施例的代码的计算机可读介质(例如,盘)。
