An electronic programming guide ("EPG") provides pictograms (120, 121, 122) and logos (110, 111, 112) to indicate what television programs are showing. The EPG information can be displayed in a window within a television screen (102) while a program is shown on the remainder of the screen (102). Thus, the viewer can know what is playing on the various channels while watching one of the channels. The EPG comprises surfaces located in virtual 3D space and a 3D graphics pipeline applies the pictograms, logos, alphanumeric text and/or video clips to the geometric surfaces. The pictograms, logos, alphanumeric data and/or video clip appereance can be modified using a remote controller (150), e.g. by changing the geometric surface position or lighting. Optionally, internet HTML pages are parsed and applied to geometric surfaces in 3D virtual space. |
