摘要:
A portable communication device (PCD) can automatically switch into different operating modes of an asymmetric communication protocol (such as USB) depending on the type of accessory connected. For example, the accessory can signal whether the PCD should operate in a first mode or a second mode using a hardware indicator such as identification resistor across two pins of a multi-pin connector and/or a software indicator such as a command protocol. The PCD can detect the accessory's signal and switch to the operating mode requested by the accessory.

Embodiments disclosed herein provide for capability identification for accessories coupled with a mobile computing device. During capability identification an accessory can request capability information from a mobile computing device. In some embodiments, the accessory can specifically request capability information associated with a specific lingo. In response, the mobile computing device can respond with a message that indicates the capabilities of the mobile computing device that are supported. In some embodiments, the capabilities can be those capabilities associated with the specified lingo. In some embodiments, if the mobile computing device does not support a lingo, then the mobile computing device can respond to the request from the accessory with a negative acknowledgement.

Circuits, methods, and apparatus that provide compatibility among incompatible accessories and portable media players. One example provides an adapter having a connector receptacle to mate with an accessory's connector insert and a connector insert to mate with a portable media player's connector receptacle. Another example provides an adapter having a direct connection between pins on the connector insert and pins on the connector receptacle that are used for compatible signals. Another example provides an adapter including a DC-to-DC converter that receives a first power supply from an accessory and provides a second power supply to a portable media player. Another translates signals using different signaling technologies. Authentication and identification circuitry may also be included. Other examples may employ wireless technologies instead of either or both the connector insert and connector receptacle.

Message notifications to an accessory from a mobile communication device are provided according to some embodiments of the invention. When a message such as a text message, email, and/or voicemail is received at a mobile communication device, the mobile communication device can notify an attached accessory that a message has been received. In response, the accessory can request the full message, media associated with the message, an attachment to the message, and/or an audio/video stream of the message for presentation to a user.

Remote user interfaces for portable media devices provided improved access by accessories to media assets and metadata stored in a database of a portable media device, enhancing a user's ability to control operation of the portable media device using a remote user interface provided by the accessory. In one example, an accessory can determine whether the database of the portable media device was updated while the portable media device was disconnected from the accessory. In a second example, an accessory can create and manage a playlist for the portable media device and can incorporate into the playlist tracks already queued for playback when the accessory connects to the portable media device. In a third example, an accessory can obtain database navigation history and initialize a database navigation interface to match the database navigation history.

Duplex audio is provided for a mobile communication device and an accessory. In some embodiments, the accessory can selectably operate in a duplex audio mode, concurrently sending audio to and receiving audio from the mobile communication device, or in another audio mode. In duplex audio mode, the accessory can enable its internal audio processing operations (e.g., echo cancellation) while the mobile communication device disables its corresponding internal operations or vice versa. The mobile communication device can control when the accessory transitions into and/or out of duplex audio mode.

An accessory communicates with a PMD to store tags associated with broadcasts in a file maintained in a storage medium of the accessory. In one embodiment, the accessory sends a command to the PMD to create or open a tag file that resides on the PMD. Once opened, the tag file is held open by the PMD until the accessory closes it (or disconnects), allowing multiple tags to be written to one file. Each time the user requests a new tag, the accessory generates a tag containing information descriptive of the broadcast material (e.g., song title, artist, radio station identifier, time of tagging, etc.) and writes the tag to the tag file using a write command to the PMD.
