JPIP (JPEG 2000 Interactive Protocol) is a compression streamlining protocol that works with
JPEG 2000
JPEG 2000 (JP2) is an image compression standard and coding system. It was developed from 1997 to 2000 by a Joint Photographic Experts Group committee chaired by Touradj Ebrahimi (later the JPEG president), with the intention of superseding their ...
to produce an image using the least bandwidth required. It can be very useful for medical and environmental awareness purposes, among others, and many implementations of it are currently being produced, including the

camera's pictures, among others.
JPIP has the capacity to download only the requested part of a picture, saving bandwidth, computer processing on both ends, and time. It allows for the relatively quick viewing of a large image in low resolution, as well as a higher resolution part of the same image. Using JPIP, it is possible to view large images (1 gigapixel) on relatively light weight hardware such as PDAs.
Healthcare Applications of JPIP
JPIP helps address the growing need to access medical images fast while enabling interoperability in clinical and radiological system. Typical healthcare applications for JPIP streaming include teleradiology,
health information exchange,
electronic medical records,
electronic health records

Interoperability using JPIP
JPIP is a client/server communication protocol defined in Part 9 of the JPEG2000 suite of standards, (ISO/IEC 15444-9). It is a transfer syntax in
