Standard computer file format for storing graphic images in a compressed form for general use. JPEG images are compressed using a mathematical algorithm. 2000 Interactive Protocol (JPIP JPIP JPEG Interactive Protocol ) by the DICOM (medical, standard) DICOM - (From Digital Imaging and COmmunications in Medicine) A standard developed by ACR-NEMA (American College of Radiology - National Electrical Manufacturer's Association) for communications between medical imaging devices. Standards Committee. JPIP is a client/server image streaming protocol defined by the JPEG 2000 standard (ISO/IEC ISO/IEC International Organization for Standardization/International Electrotechnical Commission (ITU-T M 3000) 15444-9), and joins JPEG 2000 image compression as a DICOM standard for the encoding and transport of medical images and data. Aware provides a JPIP-compliant client/server reference implementation with API along with its JPEG 2000 software development kit products.
While similar functionality is currently offered with proprietary client/server products, JPIP introduces the first fully DICOM-compliant solution. A standards-based approach provides for the networking of disparate server and client software, enabling a dramatic increase in the ability to share medical images and collaborate on diagnoses. Aware has played an instrumental role in the adoption of JPEG 2000 standards by DICOM, serving as co-chair for DICOM WG4 for compression and as liaison between ISO/IEC SC 29 and DICOM.
"The size and quantity of image data generated by scanning equipment is growing exponentially, as is demand for broad sharing of centrally stored images," commented Rob Mungovan, vice president at Aware. "JPIP provides a bridge across this growing chasm with an advanced, standards-based solution, and leverages the inherent strengths of JPEG 2000 compression."
DICOM standards previously allowed only for transfer of entire image files, where JPIP adds the capability to transport portions of JPEG 2000 images on demand, such as a low-resolution version or a region of interest within an image. Using JPIP, images can also be displayed progressively by quality layer. This progressive capability enables faster transmission and viewing in client/server environments for tasks such as preview, pan, zoom, and scroll. The larger the dataset and more constrained the bandwidth of the network, the greater the benefit of JPIP. The streaming of image data works well with lossless See lossless compression.
(algorithm, compression) lossless - A term describing a data compression algorithm which retains all the information in the data, allowing it to be recovered perfectly by decompression.
Unix compress and GNU gzip perform lossless compression. compressed images and helps to overcome the lower compression ratios offered by lossless compression by providing the client with a viewable image very quickly, and then progressively building to full fidelity as additional image data arrives from the server. JPIP also allows for caching models that eliminate the retransmission Retransmission might refer to:

Aware, Inc. was the first commercial organization in the world to provide a wavelet based image compression algorithm to original equipment manufacturers for use in medical systems. Our active development and commercialization efforts have helped promote the adoption of wavelet-based compression by the medical industry. Today some form of wavelet algorithm is used by all of the major medical imaging systems providers. Aware is also a leader in the development and marketing of DSL DSL
