The LEADTOOLS JPIP (JPEG 2000 Interactive Protocol) Module supports interactive streaming of large images and associated image data using the minimum possible bandwidth. It is especially well-suited to using internet connections for viewing and manipulating large medical, geospatial, and very-high-resolution camera images stored on remote servers. It is an implementation of the JPEG2000, part 9 standard (ISO/IEC 15444-9), including both meta-data and code-stream elements.

LEADTOOLS JPIP client/server architecture allows storage of very large, compressed JPEG2000 images at the server, plus transmission of image resolution, quality and region of interest (ROI) as specified by a client. This allows client applications to interact with a stored image without  transmitting the entire image, or decoding the entire image code-stream. The server and client components include a number of options for controlling this image streaming and decoding.

The LEADTOOLS JPIP SDK comprises high level components that developers can easily plug into enterprise client/server applications, allowing them to immediately start streaming high-resolution images under low HTTP bandwidth connections.

Key Features:

• Fast, flexible code updates: LEAD's managed code does not depend on third-party libraries.

• Optimizes network efficiency through progressive image transmission, without sending redundant data.

• Fast image viewing through progressive decoding of images resolutions, tiles, and components.

• Suitable for browsing lossless high-resolution medical and geospatial images.

• Supports JPEG2000 code-streams and multiple file formats (J2K, JP2 and JPX).

• Supports streaming over HTTP V1.1 transport protocol

Server Component:

• Gives fine control over allocated server bandwidth, total server bandwidth, client connections bandwidth, and chunk size.

• Enables conservation of server resources through setting the maximum number of client connections, client lifetime, and timeouts.

• Enables performance enhancement through splitting the streaming process among multiple servers running on different machines.

• Supports interactive client requests and server response handling

Client Component:

• Decodes low image resolutions and progressively decodes higher resolutions on user request.

• Decodes user-requested regions of interest (ROI), component, and quality.

• Enables local caching of images information for faster future viewing.

• Controls the amount of data delivered in each request.
