Abstract
A server fulfills region and time of interest (RTI) requests for images from multiple users. The server includes a receiver for receiving a RTI request from a user, a processor for assembling a compressed image based on the RTI request, and a transmitter for transmitting the compressed image to the user. The processor is configured to extract a first portion of the compressed image from a local storage device. If the first portion is insufficient to fulfill the RTI request, the processor is configured to request a second portion of the compressed image from another server, and combine the first and second portions of the compressed image to fulfill the RTI request from the user. The compressed image includes an image compressed by a JPEG 2000 compressor.
