This Recommendation I International Standard 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 ITü-T Rec. X.680 (1994) I ISO/IEC 8824-1:1995, ITU-T Rec. X.681 (1994) I ISO/IEC 8824-2:1995, ITU-T Rec. X.682 (1994) I ISO/IEC 8824 3:1995, and ITü-T Rec. X.683 (1994) I ISO/IEC 8824-4:1995, 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 .
These encoding rules are used at the time of communication (by the presentation service provider when required by apresentation context).
