摘要： Digital audio can be transferred between a portable media player and an accessory. In one embodiment, an interface protocol is used to determine the sample rate capabilities of an accessory, allowing digital audio data for a track to be transmitted to the accessory at a sample rate supported by the accessory. When the sample rate of an audio track is not supported by the accessory, the media player can convert the sample rate of the track to a rate supported by the accessory and transmit the track after conversion. The media player also can use the interface protocol to inform the accessory if the sampling rate should be changed, e.g., due to tracks having different sample rates. The accessory then can send a request to the media player to change the sample rate. The media player then can transmit the digital audio data using the new sample rate.

摘要翻译： 数字音频可以在便携式媒体播放器和附件之间传输。 在一个实施例中，使用接口协议来确定附件的采样速率能力，允许将轨道的数字音频数据以附件支持的采样率传输到附件。 当附件不支持音轨的采样率时，媒体播放器可将轨道的采样率转换为附件支持的速率，并在转换后传输轨道。 媒体播放器还可以使用接口协议来通知附件，如果采样率应该被改变，例如由于轨道具有不同的采样率。 然后，附件可以向媒体播放器发送请求以更改采样率。 然后，媒体播放器可以使用新的采样率来发送数字音频数据。

摘要： A connector is disclosed. The connector comprises a plurality of universal serial bus (USB) pins, and a plurality of pins for additional functionality, wherein the connector can engage a conventional USB connector or a connector that also utilizes the plurality of pins. Accordingly, in the present invention, a male and female connectors are provided that include additional pins within the connector that provide for additional functionality. This is accomplished utilizing the standard interface of the USB connector but adding additional pins around that interface to provide this functionality.
