JPIP proxy server for remote browsing of JPEG2000 images

Livio Lima, David Taubman, Riccardo Leonardi

Abstract: The JPEG2000 image compression standard offers scalability features in support of remote browsing applications. In particular Part 9 of the JPEG2000 standard defines a protocol called JPIP for interactivity with JPEG2000 code-streams and files. In client-server application based on JPIP, a client does not directly interact with the compressed file, but formulates requests using a simple syntax which identifies the current ldquoFocus Windowrdquo. In this kind of application particularly useful could be a proxy server, that potentially can improve the performance of the system through a better use of the network infrastructure. The aim of this work is to propose a proxy server with JPIP capabilities and shows the benefits that can be brought to remote browsing applications.
