本文档指定了一组基本八位字节编码规则(BASIC-OER)，其可用于导出用于Rec中定义的类型的值的传输语法。ITU-T X.680 ISO/IEC 8824-1，建议。那个？T X.681 ISO/IEC 8824-2，建议。ITU-T X.682 ISO/IEC 8824-3，建议。ITU-T X.683 ISO/IEC 8824-4。本文档还指定了一组规范八位字节编码规则（CANONICAL-OER），它提供了对基本八位字节编码规则的约束，并为任何给定的ASN.1值生成唯一的编码。在这些编码规则的规范中隐含的是，它们也将用于解码。 本文档中指定的编码规则: -在通信时使用； -旨在用于编码/解码速度是选择编码规则的主要考虑因素的环境中； -允许通过为Rec中描述的所有形式的可扩展性添加额外值来扩展抽象语法。ITU-T X.680 ISO/IEC 8824？1.

This document specifies a set of Basic Octet Encoding Rules (BASIC-OER) that may be used to derive a transfer syntax for values of the types defined 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, Rec. ITU-T X.683 | ISO/IEC 8824-4. This document also specifies a set of Canonical Octet Encoding Rules (CANONICAL-OER) which provides constraints on the Basic Octet Encoding Rules and produces a unique encoding for any given ASN.1 value. It is implicit in the specification of these encoding rules that they are also to be used for decoding.
The encoding rules specified in this document:
– are used at the time of communication;
– are intended for use in circumstances where encoding/decoding speed is the major concern in the choice of encoding rules;
– allow the extension of an abstract syntax by addition of extra values for all forms of extensibility described in Rec. ITU-T X.680 | ISO/IEC 8824？1.
