本文件规定了一套基本的八位字节编码规则（Basic-OER），可用于为记录ITU-T X.680 | ISO/IEC 8824-1，记录ITU？T X.681 | ISO/IEC 8824-2，记录ITU-T X.682 | ISO/IEC 8824-3，记录ITU-T X.683 | ISO/IEC 8824-4中定义的类型的值推导传输语法。本文档还指定了一组规范八位组编码规则（Canonical-OER），该规则对基本八位组编码规则提供约束，并为任何给定ASN生成唯一编码。1.价值观。这些编码规则的规范中隐含着它们也将用于解码。 本文档中指定的编码规则: -在交流时使用； –？用于编码/解码速度是选择编码规则的主要考虑因素的情况； –允许通过为建议ITU-T X.680 | ISO/IEC？8824？1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。

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.
