scope:

This draft European Telecommunication Standard (ETS) is intended to extend the coded representation of the Multimedia and Hypermedia information coding Experts Group (MHEG) script object class.

The draft ETS specifies the MHEG Script Interchange Representation (MHEG-SIR) for the contents of script objects.

The MHEG-SIR consists of the encoding of the script data component of the MHEG script class. It applies to MHEG part 1 (ISO/IEC 13522-1 [1]) conforming script objects whose script classification component is script and whose script encoding identification component is MHEG-SIR.

NOTE: These values will be registered according to MHEG part 4 (ISO/IEC 13522-4 [6]) provisions.

MHEG engines are system or application components which handle, interpret and present MHEG objects. This ETS also specifies the semantics of MHEG-SIR interchanged scripts. The semantics are defined in terms of minimum requirements on the behaviour of MHEG engines which support the interpretation of MHEG-SIR scripts.
