Function Documentation

MHEG5Ingredient* asn1_createTokenGroup ( fpa1_syntaxList * listPtr )

Decodes TokenGroup class. Refer to MHEG5 Specification (ISO/IEC 13522-2:1996), Appendix A, section [A.22] for details of ASN.1 representation.

Parameters

listPtr pointer to current fpa1_syntaxList item

Returns: Pointer to TokenGroup class being decoded.

asnErr asn1_decodeTokenGroup	(	fpa1_syntaxList *	listPtr,
		MHEG5TokenGroup *	tokenGrp
	)

Decodes TokenGroup class. Refer to MHEG5 Specification (ISO/IEC 13522-2:1996), Appendix A, section [A.22] for details of ASN.1 representation.

Parameters

listPtr	pointer to current fpa1_syntaxList item
tokenGrp	Pointer to TokenGroup class being decoded.

Returns: asnErr

U32BIT asn1_getTokenGroupItemCount ( fpa1_syntaxList * currItem )

Gets total count of TG Items and Action Slots.

Parameters

listPtr pointer to current fpa1_syntaxList item

Returns: U32BIT - top 16 bits for toekn count, 16 lsb for action-slot count.
