Function Documentation

unsigned int QSEC_decode	(	QSEC_expansion *	exp,
		QSE_ebfEvt *	oevt,
		const unsigned int *	ievt
	)

Decode the event held in the expansion structure into the QSE_evt structure.

Parameters:

	exp	Pointer to the expansion structure holding the histograms and encoder context
	oevt	Pointer to the location to output the decoded event
	ievt	Pointer to the location to input the encoded event

Returns:

Length, in bytes, of the event data

void QSEC_update	(	QSEC_expansion *	exp,
		EBF_gem *	gem,
		unsigned int *	seq,
		const unsigned int *	ievt
	)

Decode the GEM contribution and extract the 17 bit event sequence.

Parameters:

	exp	Pointer to the expansion structure holding the histograms and encoder context
	gem	Pointer to the location to place the decoded GEM contribution
	seq	Pointer to the location to place the 17-bit event sequence number
	ievt	Pointer to the location to input the encoded event number for use in QSE_ctxUpdateAtEvent
