标准摘要
[中文适用范围]： 本国际标准建立了一种适用于来自有效载荷仪器的二维数字空间图像数据的数据压缩算法，并规定了如何将此压缩数据格式化为段，以便在接收端进行解压缩。数据压缩的源编码是一种在数据系统中使用的方法，用于减少数字数据的体积，以实现包括但不局限于以下方面的好处：减少传输信道带宽；减少缓冲和存储需求；在给定的速率下减少数据传输时间。范围和适用领域在附带的CCSDS出版物的子条款1.2和1.3中进一步详细说明。 [外文原描述]： ISO 26868:2009 establishes a data compression algorithm applicable to two-dimensional digital spatial image data from payload instruments and specifies how this compressed data is formatted into segments to enable decompression at the receiving end. Source coding for data compression is a method utilized in data systems to reduce the volume of digital data to achieve benefits in areas including, but not limited to: reduction of transmission channel bandwidth; reduction of the buffering and storage requirement; reduction of data-transmission time at a given rate.
