Abstract
A system for continuously presenting audio/video data. The data for the entire program is too large to be completely loaded into memory at one time; therefore, the data is divided into a set of overlapping zones. Each zone is divided into subzones. Two overlapping zones overlap because they both share a common (or overlapping) subzone. When a user moves from a first zone to a second zone, the user will first move into the overlapping subzone prior to moving to the second zone. While the user is in the overlapping subzone, data for the second zone is loaded into memory. Thus, when the user leaves the overlapping zone and enters the second zone, data for the second zone is presented in a continuous fashion.
