    • Improved techniques for rendering a peripheral device removable (e.g., unpluggable) are disclosed. According to one aspect of the invention, the peripheral device is rendered removable from a host computer without preparatory user actions. In effect, the peripheral device can be automatically prepared for removal in the event that its user removes (unplugs) it from its host computer. According to another aspect of the invention, the peripheral device includes a data storage device that is mounted to a file system of the other computer when the other computer desires access to the data storage device. Otherwise, the data storage device is normally unmounted so that if the peripheral device were to be removed (e.g., unplugged) no harm or damage to data stored therein would occur. These aspects of the invention can be utilized alone or in combination with one another. The invention is particularly well suited for peripheral devices that are media players which are “hot” unpluggable without detrimental consequences.
    • 公开了用于呈现外围设备可移除(例如,不可插拔)的改进的技术。 根据本发明的一个方面,外围设备可以从主计算机上取出,而无需预备用户动作。 实际上,外围设备可以在其用户从其主机中删除(拔出)的情况​​下自动准备移除。 根据本发明的另一方面,当另一计算机希望访问数据存储设备时,外围设备包括一个数据存储设备,该数据存储设备被安装到另一台计算机的文件系统。 否则,数据存储设备通常被卸载,使得如果外围设备被去除(例如,拔掉),则不会对其中存储的数据造成危害或损坏。 本发明的这些方面可以单独使用或者彼此组合使用。 本发明特别适用于作为媒体播放器的外围设备,这些设备是“热”可拔出的,而没有有害后果。

    • Improved techniques to utilize and manage a group of media items (or media assets) on a computing device are disclosed. The group of media items can be utilized and managed at a host computer for the host computer as well as a media device (e.g., media player) that can couple to the host computer. One popular example of a group of media items is know as a playlist, which can pertain to a group of audio tracks. One aspect pertains to a graphical user interface that enables a user to trade-off storage capacity of a media device between media asset storage and data storage. Another aspect pertains to a graphical user interface that assists a user with selecting media items to fill a group of media items. Still another aspect pertains to providing a persistent media device playlist at a host computer. Yet still another aspect pertains to imposing capacity limits to a playlist, such as a media device playlist.
    • 公开了在计算设备上利用和管理一组媒体项目(或媒体资产)的改进的技术。 可以在用于主计算机的主计算机以及可以耦合到主计算机的媒体设备(例如,媒体播放器)上使用和管理媒体项目组。 一组媒体项目的一个流行示例被称为播放列表,其可以涉及一组音轨。 一个方面涉及图形用户界面,其使得用户能够在介质资产存储和数据存储之间权衡媒体设备的存储容量。 另一方面涉及一种图形用户界面,其帮助用户选择媒体项目来填充一组媒体项目。 另一方面涉及在主计算机上提供持久媒体设备播放列表。 然而,另一方面涉及将播放列表(如媒体设备播放列表)强加容量限制。

    • 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.
    • 公开了一种基于网络分发内容的方法和系统。 内容的分发不仅安全,而且受到控制。 该安全性限制了在下载期间以及在服务器或客户端存储时对媒体文件内容的访问。 在一个实施例中,每个媒体文件用不同的随机生成的密钥加密。 对媒体文件分发的控制可用于限制媒体文件从客户端到其他客户端的后续分发。 在另一个实施例中,该控件可以允许媒体文件在与相同用户相关联的有限数量的不同客户端上共享。 客户端可以根据应用而变化,但通常是具有存储器的计算设备。 通常,客户端是能够向其用户存储和呈现内容的个人计算机或其他计算设备。
