Abstract:
A camera capable of capturing still images and video and included in a portable media device can be controlled remotely using an accessory. The accessory can register with the PMD to automatically receive notifications whenever there is a change in the camera state. The camera states can include mode, operation status, and configuration settings. The accessory can send instructions to a camera application that interfaces with the camera to control the camera. The accessory can remotely activate the camera, change camera mode, and send instructions to operate the camera. The accessory and the PMD can concurrently control the camera. The PMD can send the captured still images and recorded video to the accessory for preview and receive instructions from the accessory on disposition of the still images and the video.
Abstract:
An accessory can communicate wirelessly with a host device such as a portable electronic device. Existing accessory protocols developed for wired communication can be used without modification, and a wireless network connecting the two devices can provide a transport or channel connecting the two devices. Establishing a wireless channel can involve the active participation of both devices. For instance, the host device can create and identify virtual port to be used by the accessory, after which the accessory can initiate communication on that virtual port. A host device can be configured to automatically connect to certain accessories upon detection of that accessory on a wireless network under various specific conditions. Encryption of accessory-protocol communications between an accessory and a host device is also provided.

Abstract:
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.
Abstract:
Embodiments disclosed herein provide for identification processes and/or procedures for accessories coupled with a mobile computing device. During identification an accessory can communicate lingo information that includes only those lingoes the accessory can use while coupled with the mobile computing device. The accessory can also communicate accessory protocol information to the mobile computing device during identification. The accessory can be limited to using only those lingoes and/or those protocols identified during identification. Various other accessory information, capabilities, preferences, etc. can also be communicated to the mobile computing device during identification.
Abstract:
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.
Abstract:
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.
Abstract:
Techniques for facilitating communication between a portable media device (PMD) and an accessory via multiple communication paths. The accessory has a unique accessory identifier that it can send to the PMD upon establishing a connection via each communication path. The PMD can determine whether the same accessory is connected via multiple communication paths based on the accessory identifier received via each communication path. The PMD can route information to the accessory and control routing of information from the accessory based on the set of communication paths that are currently connected and can dynamically change the routing as communication paths are connected and disconnected.
