信息技术.以压缩方式储存的数字影像(JPEG)2000图像编码系统:无线电系统

[中文适用范围]： 此建议|国际标准以可扩展的方式定义了语法和方法，用于防止在传输符合 ITU-T Rec. 的 JPEG 2000 码流期间可能发生的错误。 T.800 | ISO/IEC 15444-1。 在本建议中|在国际标准中，这些被称为无线JPEG 2000、“JPWL”，并且使用JPWL的应用程序被称为“JPWL系统”。 JPWL 指定了一组工具，其中包括纠错和信令所必需的 JPEG 2000 码流附加数据结构和错误保护技术。 此建议|国际标准包括语义的定义，并建议如何使用这些定义。 [外文原描述]： ISO/IEC 15444-11:2007 provides a syntax that allows JPEG 2000 coded image data to be protected for transmission over wireless channels and networks. Protection services include error detection and correction capability for header and bitstream, description of the error sensitivity of different portions of the compressed data, and description of possible residual errors in the compressed data. The syntax allows these protection services to be applied to coded image data in part or in their entirety. These services are designed so as to maintain the inherent features of JPEG 2000, such as scalability and access to various spatial areas, resolution levels, colour components and quality layers, while providing protection services on these elements.
