An object of the present invention is to provide a media player system. Certain aspects of the A media player system relates docking station (178) that allows a media player (174) to communicate with other media devices. Another aspect of the media player system relates to a wireless media player system that includes one or more media devices that can receive (404A) wirelessly connecting the hand held media player and the information that can send information over a wireless connection (406). Another aspect of the media player system pertains to a method of connecting a hand held media player to another device wirelessly. 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, locally the media item to the hand held media player, said wirelessly It comprises transmitting the selected remote recipients. Another aspect of the media player system relates handheld music player that includes a transmitter for transmitting information over a wireless connection. Wherein the transmitter is configured to at least transmit a continuous music feed a receiver capable of receiving information from the transmitter in the wireless connection to one or more personal tuning devices including, respectively.

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).

Accessory authentication for electronic devices

A method, system, and connector interface for authenticating an accessory. A method includes performing an authentication operation and allowing the accessory to access the media player during the authentication operation; if the authentication operation fails, the accessory is locked out from any further access to the media player. The authentication operation can include, e.g., validating authentication information included in an authentication certificate provided by the accessory and/or validating a digital signature provided by the accessory. 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 control access to the media player.

Method and system for authenticating an accessory

A method and system for allowing a media player to transfer digital audio to an accessory is disclosed. The method and system comprises sending a play command to the media player; returning information about the media player; and providing digital audio to the accessory based upon the information about the media player. In a system and method in accordance with the present invention a plurality of commands allow a media player to transfer digital audio to an accessory. These commands are used by the media player to gather a list of supported sample rates from the accessory and to inform the accessory of the media player's information.

Method and System For Allowing A Media Player To Transfer Digital Audio To An Accessory

Methods and systems for improved interaction between media devices and accessory devices are disclosed. In one embodiment, the improved interaction can operate to configure a user interface of a media device dependent on the type or condition of an accessory device. In the same or another embodiment, the improved interaction can exchange status information between a media device and an accessory device that can influence operation of either or both of the devices.

Media delivery system with improved interaction

A video/audio media player supports various flash memory cards, and includes several flash memory card sockets, a digital signal processor, a microprocessor, a transfer interface, a video encoding unit, and an audio decoding unit to access various flash memory cards. It supports USB and 1394 interfaces, and can be independently used in HDTVs, PCs, or Hi-Fi Systems for video steam encoding/decoding, digital/analog data conversion, etc. It enhances the interoperability of flash memory cards and brings convenience to video/audio data transfer.
