Abstract: Methods and apparatuses to provide advertising based on pre-computed sub-playlists are described. The sub-playlists are generated based on one or more demographic characteristics. One or more sub-playlists are used to generate a playlist for a particular user or group of users. In one embodiment, the sub-playlists are generated at a network operations center or other location remote from the device on which the ultimate playlist is displayed; however, the sub-playlists can be generated locally or on a local network device. One or more sub-playlists corresponding to the demographic characteristics of a device user or group of users are combined to provide a playlist for the user or group of users. The playlist is displayed to the user or group of users.

Abstract: Methods and apparatuses for level-based network access restriction are described. A user of network resources logs on to the network according to any appropriate security procedure. The user is provided access to a known, trusted resource as a starting point. From the starting point, the user can access other network resources by following links from the starting point or in another manner. The network resources accessed by the user are analyzed to determined whether the resource is a trusted resource. If the resource is a trusted resource, the user is allowed to follow a predetermined number of links away from the trusted resource before access is denied.

Abstract: A method and apparatus for implementing a multiple-browser architecture is described. In one embodiment, the apparatus launches an application program in response to a trigger event. In addition, the apparatus maintains a history list corresponding to the launched application and allocates an application entity within an existing application window on the computer system. Further, the apparatus displays content data corresponding to the application program within the application window.

Abstract: A method and apparatus for navigating within a three dimensional graphic display space and manipulating information and data represented by objects in display space. The method and apparatus presents users with a vastly expanded view of their data, displayed with a richer dimensionality. Data objects represented by graphic objects are arranged into a navigable landscape representing the containership and contextual relations of the underlying data. The graphic objects are columns, pedestals and disks, which represent data blocks, cells, and comparative values respectively. The columns rest on the pedestals. The disks are located with respect to the top of the column to signify a comparative attribute. The pedestal rest upon a ground plane. The ground plane represents a threshold value. Data attributes may be represented by visual, textual, executable, or audible characteristics of the display.

Abstract: A method and apparatus are presented for displaying three-dimensional navigable display space containing an aggregation of graphical objects and an overview of the aggregation of display objects. An altered perspective is provided by compressing the horizontal dimension of the displayed objects so that a user can see a representative overview of the entire aggregation of display objects that have been selected for display together on a display screen. The compressed component is expanded so that the objects appear wider as a navigator approaches the displayed objects. A spotlight shines down on objects responsive to a data query. The spotlight serves as a navigation aid to the navigator so that highlighted items are visible from a distance and can be easily located.
