Abstract: Network content delivery apparatus and methods based on content compiled from various sources and particularly selected for a given user. In one embodiment, the network comprises a cable television network, and the content sources include DVR, broadcast, nPVR, and VOD. The user-targeted content is assembled into a playlist, and displayed as a continuous stream on a virtual channel particular to that user. User interfaces accessible through the virtual channel present various functional options, including the selection or exploration of content having similarity or prescribed relationships to other content, and the ability to order purchasable content. An improved electronic program guide is also disclosed which allows a user to start over, record, view, receive information on, “catch up”, and rate content. Apparatus for remote access and configuration of the playlist and virtual channel functions, as well as a business rules “engine” implementing operational or business goals, are also disclosed.

Abstract: An apparatus, systems and methods control access to an enhancement within a trigger. A portion of a trigger is encrypted and included within the trigger. The trigger with the encrypted portion is then included within a signal. When it is determined that a signal is received with the trigger, the encrypted portion is decrypted and compared to predetermined criteria. If the decrypted portion meets the predetermined criteria, display of an enhancement within the trigger is allowed.

Abstract: Methods, devices and systems are provided that display images in a manner that provides for effective space management. At least one item is horizontally displayed in a first display area. Upon selection by a user of at least one item from the first display area, an indication of the at least one item is vertically displayed in a second display area.

Abstract: A “Rendering Process and Method for Digital Map Illumination Intensity Shading” is disclosed that assigns an illumination intensity to pixels in a video display imaging a mapped terrain. The process comprises the steps of: providing a rectangular grid array of altitude values covering an area to be shaded. Each altitude value has a map position characterized by a coordinate location referenced to a first and second coordinate axes crossing orthogonally at an origin. Each coordinate location has a first and second value. Each first and second value characterizes the distance of the respective coordinate location from the origin. The map area is divided into an array of contiguous triangles. Each triangle area has a perimeter bounded by three straight line segments passing between three coordinate locations. The video display has pixel areas that corresponding to each respective triangle area. A normal vector is calculated for each triangle area.
