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.

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.

Circuits, methods, and apparatus that allow sports or other equipment, such as gym or other cardio equipment, to write data to a media player. Examples further provide the uploading of this data to a computer and third-party website. To monitor progress, the third-party website can be used to track workout data over time. The third party-website can also collect data from other users, which is particularly useful for providing a competitive environment. This data can then be graphically displayed in various ways to provide encouragement.

摘要:
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.
