摘要:
An interface and protocol allow a media player to communicate with external accessories over a transport link. The protocol includes a core protocol functionality and a number of accessory lingoes. Examples of accessory lingoes include a microphone lingo, a simple remote lingo, a display remote lingo, an RF transmitter lingo, and an extended interface lingo.

A method, system, and connector interface for transferring status information between a media player and an accessory. The method includes determining, by the accessory, when a button event occurs; and transmitting, by the accessory, at least one button status command to the media player, where the one or more button status commands comprise a context-specific button status command and at least one command associated with a particular media type. According to the method and system disclosed herein, the media player and accessory may utilize a plurality of commands in a variety of environments such as within a connector interface system environment to facilitate the transfer of status information.
摘要:
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.

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.

摘要:
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.
