ISO/IEC 15444-9:20 23本文档以可扩展的方式定义了用于根据Rec中的定义对JPEG 2000码流和文件进行远程询问和可选修改的语法和方法。ITU-T T.800 ISO/IEC 15444-1和Rec的其他成员。ITU-T T.8xx ISO/IEC 15444-x系列建议标准。在本文档中，定义的语法和方法被称为JPEG 2000交互协议“JPIP”，并且使用JPIP的交互应用被称为“JPIP系统”JPIP规定了由客户端和服务器之间的一系列结构化交互组成的协议，通过该协议，图像文件元数据、结构和部分或全部图像码流可以以避免或最小化客户端不需要的信息的通信的方式进行交换。本文档包括要交换的语义和值的定义，并建议如何使用各种现有的网络传输来传递这些内容。使用JPIP，可以以各种兼容的方式完成以下任务:-交换能力；-在会话中使用的能力的协商；-从各种容器请求和传输以下元素，例如JPEG 2000文件、JPEG 2000码流和其他容器文件:？选择性数据段；？选择性和明确的结构；？图像或其相关元数据的一部分。

ISO/IEC 15444-9:2023 This Document 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 document, 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 document 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.
