Abstract: A circuit arrangement (40) and display apparatus are described for use in 3-D graphics, where 2-D texture maps stored at different resolutions in a pyramidal array are indexed by a pair of texture coordinates and an associated level coordinate (L). In order to introduce depth cues to the 2-D transformed image of the 3-D environment, a focus depth (F) for the image is specified and those image components having a depth (z) other than the focus depth have their texture blurred to direct the viewer's eye to the depth of interest. The texture blurring is introduced by applying an offset (FS) to the level coordinate (L) indexing the pyramidal array in an amount determined by the distance to the focus depth.

Abstract: A broadcast enhancement system and method for enhancing a received television broadcast signal using a received enhancement signal, at least one of which is prepared for chroma keying. The system is configured to intercept the television broadcast signal before it is passed to the television and to apply chroma keying to superimpose the enhancement signal to the television broadcast signal before passing the superimposed signal to the television.
