    Abstract: A method and system for network-based distribution of content are disclosed. The distribution of content is not only secure but also controlled. The security restricts access to content within media files during downloads as well as while stored at a server or client. In one embodiment, each media file is encrypted with a different, randomly generated key. The control over the distribution of the media file can serve to limit the subsequent distribution of media files from clients to other clients. In another embodiment, the control can permit media files to be shared on a limited number of different clients affiliated with the same user. The clients can vary with application but generally are computing devices that have memory storage. Often, the clients are personal computers or other computing devices that are capable of storing and presenting content to their users

    Abstract: Improved techniques for interaction between a host computer (e.g., personal computer) and a media player are disclosed. According to one embodiment, interaction between a host device (e.g., host computer) and a media player can be performed over a wireless channel. The interaction over the wireless channel can be used to automatically synchronize media contents stored on the media player with media contents stored on the host device. According to another embodiment, interaction between a host device and a media player, such as automatic synchronization of media contents stored on a media player with media contents stored on a host device, can be restricted. In still another embodiment, synchronization can be automatically performed when the media player is placed in a docking station that supports wireless communications.
