1 Scope
This Recommendation | International Standard[1] defines, in an extensible manner,
syntaxes and methods for the remote interrogation and optional modification of JPEG
2000 codestreams and files in accordance with their definition in Rec. ITU-T T.800 | ISO/IEC 15444-1 and other members of the Rec. ITU-T T.8xx | ISO/IEC 15444-x family of Recommendations | Standards.
In this Recommendation | International Standard, the defined syntaxes and methods
are referred to as the JPEG 2000 Interactive Protocol, "JPIP", and interactive applications
using JPIP are referred to as "JPIP systems."
JPIP specifies a protocol consisting of a structured series of interactions between
a client and a server by means of which image file metadata, structure and partial
or whole image codestreams can be exchanged in a manner that avoids or minimises the
communication of information not required by client. This Recommendation | International
Standard includes definitions of the semantics and values to be exchanged, and suggests
how these can be passed using a variety of existing network transports.
With JPIP, the following tasks can be accomplished in varying, compatible ways:
-
— the exchange of capabilities;
-
— the negotiation of capabilities to use in a session;
-
— the request and transfer of the following elements from a variety of containers, such
as JPEG 2000 files, JPEG 2000 codestreams and other container files:
-
— selective data segments;
-
— selective and defined structures;
-
— parts of an image or its related metadata.
