    • Electronic devices and equipment may communicate over a wired communications path. The wired communications path may include one or more wires and may be associated with a headphone cable. Data may be conveyed in the form of a digital data stream containing multiple traffic channels. The digital data stream may include superframes, each of which has multiple frames of data. The frames of data may each contain a number of data slots. Some of the slots in a superframe may be used exclusively by a particular one of the traffic channels. Boundary slots may be shared between traffic channels. Data interface circuitry may implement a data dispersion algorithm that determines the pattern in which data from each traffic channel is distributed within each boundary slot. Transmitting data interface circuitry may merge traffic channels into a single data stream. Receiving data interface circuitry may reconstruct the traffic channels.
    • 电子设备和设备可以通过有线通信路径进行通信。 有线通信路径可以包括一个或多个电线并且可以与耳机线缆相关联。 数据可以以包含多个业务信道的数字数据流的形式传送。 数字数据流可以包括超帧,每个超帧具有多个数据帧。 数据帧可以各自包含多个数据时隙。 超帧中的一些时隙可以由特定的业务信道专门使用。 边界槽可以在通道之间共享。 数据接口电路可以实现数据分散算法,其确定在每个边界时隙内分布来自每个业务信道的数据的模式。 传输数据接口电路可以将业务信道合并成单个数据流。 接收数据接口电路可以重建业务信道。
