标准摘要
[中文适用范围]： 范围 本规范/国际标准规定了一组基本编码规则，可用于派生使用ITU-T X.680 | ISO/IEC 8824-1、ITU-T X.681 | ISO/IEC 8824-2、ITU-T X.682 | ISO/IEC 8824-3和ITU-T X.683 | ISO/IEC 8824-4中定义的类型的值的传输语法规范。这些基本编码规则也用于解码这样的传输语法，以识别正在传输的数据值。它还规定了一组规范编码规则和区别编码规则，将值的编码限制为基本编码规则提供的替代方案中的一个。 [外文原描述]： This document specifies a set of basic encoding rules that may be used to derive the specification of a transfer syntax for values of types defined using the notation specified in Rec. ITU-T X.680 | ISO/IEC 8824‑1, Rec. ITU-T X.681 | ISO/IEC 8824-2, Rec. ITU-T X.682 | ISO/IEC 8824-3, and Rec. ITU-T X.683 | ISO/IEC 8824-4, collectively referred to as Abstract Syntax Notation One or ASN.1. These basic encoding rules are also to be applied for decoding such a transfer syntax in order to identify the data values being transferred. It also specifies a set of canonical and distinguished encoding rules that restrict the encoding of values to just one of the alternatives provided by the basic encoding rules.
