    Abstract: A communication device detects sound with a microphone to produce a sound signal representative of the sound and searches the sound signal for unique inaudible sound signatures associated with a group identifier. Each sound signature identifies a respective communication device. Each sound signature is in an audible frequency band but masked to be imperceptible. If any of the sound signatures are determined to be present in the sound signal, the communication device selects one based on predetermined criteria associated with the group identifier.

    Abstract translation: 通信设备用麦克风检测声音以产生表示声音的声音信号，并且搜索声音信号以获得与组标识符相关联的独特的无声声音签名。 每个声音签名识别相应的通信设备。 每个声音签名处于可听见的频段，但是被掩盖为不可察觉的。 如果声音信号中的任何一个被确定为存在于声音信号中，则通信设备基于与组标识符相关联的预定标准来选择一个。

    Abstract: Media relay services are often used to establish sufficiently direct connections in order to enable provisioning of a real-time media service and/or improve the quality of real-time media services. However, media relay services are often gated using authentication systems that add undesirable delay to the delivery and/or access to a real-time media service, which in turn diminish the user experience. By contrast, various implementations disclosed herein include apparatuses, systems, and methods of providing low latency authentication of gated media relay services. For example, in some implementations, a method includes receiving a request for access to a gated media relay service, providing provisional access to the service until an authentication result is available, determining whether the requesting device is authorized to access the media relay service, and at least one of ending or continuing access to the media relay service based on the authentication result.

    Abstract translation: 媒体中继服务通常用于建立足够直接的连接，以便能够提供实时媒体服务和/或提高实时媒体服务的质量。 然而，媒体中继服务通常使用认证系统门控，这增加了对实时媒体服务的传递和/或访问的不期望的延迟，这进而降低了用户体验。 相比之下，本文公开的各种实现方式包括提供门控媒体中继服务的低延迟认证的装置，系统和方法。 例如，在一些实现中，一种方法包括接收对门控媒体中继服务的访问请求，提供对服务的临时访问，直到认证结果可用，确定请求设备是否被授权访问媒体中继服务，以及 基于认证结果，终止或继续访问媒体中继服务的至少一个。
