ISO 8825:2021 Information technology – ASN.1 encoding rules – Part 2: Specification of Packed Encoding Rules (PER)
CDN $351.00
Description
This document specifies a set of Packed Encoding Rules that may be used to derive a transfer syntax for values of types defined in Rec. ITU-T X.680 | ISO/IEC 8824-1. These Packed Encoding Rules are also to be applied for decoding such a transfer syntax in order to identify the data values being transferred.
The encoding rules specified in this document :
–      are used at the time of communication;
–      are intended for use in circumstances where minimizing the size of the representation of values is the major concern in the choice of encoding rules;
–      allow the extension of an abstract syntax by addition of extra values, preserving the encodings of the existing values, for all forms of extension described in Rec. ITU-T X.680 | ISO/IEC 8824‑1;
–      can be modified in accordance with the provisions of Rec. ITU-T X.695 | ISO/IEC 8825‑6.
