Improved techniques to control utilization of accessory devices with electronic devices are disclosed. The improved techniques can use cryptographic approaches to authenticate electronic devices, namely, electronic devices that interconnect and communicate with one another. One aspect pertains to techniques for authenticating an electronic device, such as an accessory device. Another aspect pertains to provisioning software features (e.g., functions) by or for an electronic device (e.g., a host device). Different electronic devices can, for example, be provisioned differently depending on different degrees or levels of authentication, or depending on manufacturer or product basis. Still another aspect pertains to using an accessory (or adapter) to convert a peripheral device (e.g., USB device) into a host device (e.g., USB host). The improved techniques are particularly well suited for electronic devices, such as media devices, that can receive accessory devices. One example of a media device is a media player, such as a hand-held media player (e.g., music player), that can present (e.g., play) media items (or media assets).

Methods and apparatus for managing power consumption in a multi-function electronic device powered by one or more batteries are provided. In one embodiment, when the power available from the one or more batteries is diminished (e.g., below a certain threshold), management of power consumption in a battery-powered electronic device (e.g., a portable electronic device) can operate or be operated to preserve one or more functions supported by the electronic device. For example, the one or more functions can be preserved by: (i) alerting a user that they should act to avoid usage of other functions that are not being preserved, and/or (ii) disabling (e.g., automatically) one or more of the other functions that are not being preserved.

A media player system is disclosed. One aspect of the media player system pertains to a docking station that allows a media player to communicate with other media devices. Another aspect of the media player system pertains to a wireless media player system that includes a hand held media player capable of transmitting information over a wireless connection and one or more media devices capable of receiving information over the wireless connection. Another aspect of the media player system pertains to a method of wirelessly connecting the hand held media player to another device. The method includes selecting a media item on the hand held media player; selecting one or more remote recipients on the hand held media player; and transmitting the media item locally to the hand held media player, and wirelessly to the selected remote recipients. Another aspect of the media player system pertains to a hand held music player that includes a transmitter for transmitting information over a wireless connection. The transmitter is configured to at least transmit a continuous music feed to one or more personal tuning devices that each include a receiver capable of receiving information from the transmitter over the wireless connection. Yet another aspect of the media player system pertains to a connector that includes a housing and a plurality of spatially separated contacts mounted within the housing. A first set of contacts are directed at a first functionality and a second set of contacts are directed at a second functionality that is different than the first functionality.

A power manager for managing power delivered to a battery operated peripheral device is disclosed. The power manager includes an input current limiter arranged to suppress a power surge associated with an insertion event by a power cable arranged to provide an external voltage. A voltage converter unit coupled to the input current limiter converts the received external voltage to a supply voltage that is transmitted by way of a main bus to a voltage sensor unit coupled thereto. During the insertion event, a comparator unit coupled to the voltage sensor, sends a first switching signal to a switchover circuit that responds by connecting the peripheral device and an uncharged battery to the main bus such that the supply voltage is provided thereto. When the battery is substantially fully charged, the switchover circuit responds by electrically disconnecting the battery so as to not overcharge the battery.

In a portable multimedia device, data is passed between a sender and receiver unit by way of voice channel only. Multimedia data is vocalized and then forwarded to a receiver unit by way of the voice channel without the use of a backend server. Once received at the receiver unit, the vocalized data can be converted to an audio signal that can then output by way of an audio output device (such as a speaker, earphone, etc.).

An improved portable media device and methods for operating a media device are disclosed. According to one aspect, the portable media device can also function as a solid-state drive for data storage. The form factor of the portable media device can be hand-held or smaller, such that it is highly portable. The portable media device can use one or more status indicators. The portable media device can also include a peripheral bus connector, a rechargeable battery, and one or more input devices. According to another aspect, the portable media device has the capability to store media device status information in persistent memory before powering down. Thereafter, when the portable media device is again powered up, the stored media player status information can be retrieved and utilized. According to still another aspect, the portable media device can form and/or traverse a media asset playlist in an efficient manner.

A graphical user interface (“GUI”) can be presented on a remote control accessory device that has user input and display devices. The GUI can be defined and managed by a portable media device that is controlled using the GUI. The portable media device can provide the accessory with a GUI image to be displayed. The accessory can send information to the portable media device indicative of a user operation of an input device in response to the displayed image. The portable media device can process this input to identify the action requested by the user and take the appropriate action, which can include updating the GUI image provided to the accessory.
