    • Systems and methods are provided to facilitate the distribution of audio signals over wireless networks. In one implementation, an audio system includes a head end having an encoder and a wireless network interface. Audio signals associated with a plurality of audio channels are processed by the encoder to provide an encoded signal in accordance with an audio codec. The encoded signal can be provided to a wireless network by the wireless network interface as a plurality of data packets associated with a network address in accordance with a wireless networking protocol, such as an IEEE 802.11 protocol. One or more remote endpoints can also be provided to receive the data packets from the wireless network, assemble the data packets to obtain the encoded signal, and extract at least one of the audio signals from the encoded signal in accordance with the audio codec. Multicast and unicast implementations are also provided.
    • 提供了系统和方法以便于通过无线网络分配音频信号。 在一个实现中,音频系统包括具有编码器和无线网络接口的头端。 与多个音频通道相关联的音频信号由编码器处理以根据音频编解码器提供编码信号。 可以根据诸如IEEE 802.11协议的无线网络协议,通过无线网络接口将编码信号作为与网络地址相关联的多个数据分组提供给无线网络。 还可以提供一个或多个远程端点以从无线网络接收数据分组,组合数据分组以获得编码信号,并根据音频编解码器从编码信号中提取至少一个音频信号。 还提供了组播和单播实现。
