摘要：An electronic programming guide (“EPG”) in accordance with the inventionprovides pictograms and/or logos, to indicate to a television viewer the televisionprograms being displayed on a television. The EPG information display format is thuseasier 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 atelevision 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 watchingone of the channels. In one embodiment, the EPG is used in conjunction with a remotecontroller 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 appliedto the geometric surfaces using a 3D graphics pipeline. The video clips can comprise videoprograms, preview clips, or video data stored on a hard drive. The appearance of thepictograms, logos, alpha-numeric data and/or video clips can be modified in response toa user actuating a control element on a remote controller. Such modification can includechanging the position of the geometric surface, or its lighting. All or some of thepictograms, logos, alpha-numeric data and video clips can be, changed over time basedon broadcast data. In one embodiment, internet HTML pages are parsed and applied togeometric surfaces in 3D virtual space.
