1. A method for rendering multimedia data comprising the steps of:
- rendering selected ones of a plurality of multimedia data, each of the multimedia data having an independent source, in a plurality of areas of a display screen forming a browse polyhedron, said rendering in accordance with the spatial orientation of said browse polyhedron andrepeating the step of rendering in response to change to said spatial orientation.

Abstract
A browsing system for multimedia uses a polyhedron to display multiple multimedia sources simultaneously. A user or software can rotate the browse polyhedron to make visible faces of the polyhedron which are hidden and can rotate the polyhedron to change the orientation of visible faces. On each face, the system renders a different video stream from the multimedia data source based on the orientation.

5. A method for browsing a plurality of different multimedia sources simultaneously on a single display comprising the steps of:
-
initializing a browse polyhedron having a plurality of faces on said display to receive a video stream of one said multimedia source, said browse polyhedron having an initial spatial orientation for said browse polyhedron, the spatial orientation of said browse polyhedron indicating which faces are visible and which faces are not visible; modifying the spatial orientation of said browse polyhedron; and displaying on said display the video stream of an assigned selected multimedia source for each visible face of said browse polyhedron based on the spatial orientation of said browse polyhedron. - View Dependent Claims (6, 7, 8, 9, 10, 11)

12. A system for browsing multiple video streams on a display screen, said system comprising:
-
a memory configured to receive frames from each video stream; a processor coupled to said memory and selectively coupled to said display screen, said processor configured to execute instructions for rendering said frames onto a browse polyhedron generated by said processor on said display screen, each video stream assigned a face of said browse polyhedron, said processor configured to receive rotation values for said browse polyhedron, said rotation values defining an orientation for said generation of said browse polyhedron. - View Dependent Claims (13, 14, 15, 16)
