Interactive wide-angle video server

Abstract

An interactive video server which enables multiple clients to independently and interactively extract views from a one or more wide-angle imagery sources is disclosed.

         19 . A method for remotely viewing wide-angle video comprising the steps of:
 outputting from a first location one or more portions of a wide-angle video image with positional information of the one or more portions in relation to said wide-angle image; and   receiving at a second location said one or more portions and said positional information, and generating one or more corresponding reduced distortion views from the one or more portions using said positional information.   
     
     
         20 . A method as recited in  claim 19  wherein said view has associated coordinates, and first location outputs said coordinates. 
     
     
         21 . A method as recited in  claim 19  wherein said view generation is based on 3D graphics techniques, using texture-mapping for stereographic projection or linear perspective projection or cylindrical projection. 
     
     
         22 . A method as recited in  claim 19  wherein said view generation is based on tabular distortion-correction. 
     
     
         23 . A method as recited in  claim 19  wherein said view generation is based on 2D transform mapping using orthogonal transform algorithms.
