    • 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。

    • Techniques for repeatedly selecting and presenting media items at a media device are disclosed. In one embodiment, media items are automatically (or dynamically) selected from a media source (e.g., list of media items) and then presented at a media device. As a result, the selected media items can be continuously selected and presented in an automated manner. In one embodiment, the automatic selection of the media items can be performed in accordance with at least one criterion. The at least one criterion can be user-specified and/or rules-based. In one embodiment, a display screen can display information pertaining to recently presented media items, media item being presented, and upcoming media items to be presented.
    • 公开了在媒体设备上重复选择和呈现媒体项目的技术。 在一个实施例中,媒体项目是从媒体源(例如,媒体项目列表)中自动(或动态地)选择的,然后呈现在媒体设备处。 结果,可以以自动的方式连续地选择和呈现所选择的媒体项目。 在一个实施例中,可以根据至少一个标准来执行媒体项目的自动选择。 该至少一个标准可以是用户指定的和/或基于规则的。 在一个实施例中,显示屏幕可以显示关于最近呈现的媒体项目,正在呈现的媒体项目和要呈现的即将到来的媒体项目的信息。
