An electronic programming guide (“EPG”) in accordance with the invention provides pictograms and/or logos, to indicate to a television viewer the television programs being displayed on a television. The EPG information display format is thus easier to recognize than prior art EPG formats. In one embodiment, the EPG pictograms have 3D characteristics. The EPG information can be displayed in a window within a television screen while a program is being shown on the remainder of the screen. Thus, the viewer can know what is playing on the various channels while he or she is watching one of the channels. In one embodiment, the EPG is used in conjunction with a remote controller that includes a help button for facilitating operation of the EPG by the user. The EPG comprises a set of geometric surfaces located in virtual 3D space. The pictograms and/or logos, along with alpha-numeric text data and video clips are applied to the geometric surfaces using a 3D graphics pipeline.

A D surface is defined in terms of a set of vertices. The D surface and a pixel array are used to generate a D image. Portions of the D surface are selectively removed using selected criteria. In one embodiment, the D surface is defined in terms of a set of triangles, and the triangles are tested for compliance with selected conditions. For example, the triangles can be tested to determine their slope. Based on these tests, the triangles are excised from the geometric surface. In one embodiment, the selected conditions are based on a combination of the slope of the triangles and the color of the pixels bound to the triangles.

A method in accordance with the invention comprises the step of providing a) pixel array and a computer model of a geometric surface, and b) providing a second array (a Z array) containing information concerning the 3D characteristics of the structure depicted in the pixel array. The Z array is used to modify the location of the geometric surface. The pixel array and modified geometric surface are then used to render an image that can be displayed on a CRT or other output device. By modifying the geometric surface model in this way, it is possible to create more realistic images.

The appearance of the pictograms, logos, alpha-numeric data and/or video clips can be modified in response to a user actuating a control element on a remote controller. In one embodiment, internet HTML pages are parsed and applied to geometric surfaces in D virtual space.

A video signal transmission system transmits a video signal and data corresponding to the location and size of active areas for some of the frames of the video signal (but not other frames of the video signal). A video reception and display system determines the location and size for the active areas based on an interpolation technique. A viewer can click on the active areas to thereby link the receiving system to a web page or other information source.

In three-dimensional graphics rendering, a method of texture mapping, or shading, applies to triangle-based graphical objects having undergone a perspective transformation. The present invention makes use of linear interpolation for determining the appropriate mapping for the interior points of each triangle, thus reducing the computation-intensive mathematical calculations otherwise required. In order to minimize visual artifacts due to high interpolation errors, the borders of each triangle are tested against a predetermined threshold, and the triangle subdivided if any of the borders contain a maximum error which exceeds the threshold. The subdivision continues until all triangle sides have maximum errors that are less than the threshold value. Linear interpolation is then used to determine all mappings for the sides and interior points of the triangle. In alternative embodiments, the triangle is subdivided without using recursive methods.

A method, non-transitory computer readable media, and Apparatus is provided for viewing a second content item while a first content item plays an advertisement. When the first content item is changed to a second content item on a display, a window region displays an advertising item related to the advertisement. The advertising item in the window region is modified when the advertisement has ended, alerting the user the advertisement is over. In another embodiment, the advertisement comprises a first and second commercial played in succession, and the advertising item in the window region comprises a first and second product item. In this embodiment, the window region displays the first product item when the first commercial is played in the advertisement, and the second product item when the second commercial plays in the advertisement.

A video system comprises a screen. Interactive linking is provided based on a representative set of region-based templates. Each template can be associated with said screen. The template comprises a set of active areas (usually non-intersecting), that can be actuated by moving a cursor to those areas, to thereby invoke a process or link. The link can be to a web page or other information source. In addition to template usage for surfing of active screen areas, templates can be used for secure link (process) activation. Each region can be considered as a symbol ("letter") in the password. By using mouse or similar device user can click ("type) a sequence of symbols to follow an existing password.

A system that can store electronic program guide information using 3D graphics is disclosed. In a particular embodiment, a data filter and a text-to-image converter are used for converting filtered data into a set of digital images that are defined as a set of texture maps. In order to apply those texture maps, a memory analyzer analyzes the set-top box layout and indicates available memory types. The memory analyzer controls a memory distributor for distributing texture maps into the appropriate types of memory.
