Function Documentation

dvbpsi_vbi_dr_t * dvbpsi_DecodeVBIDataDr

(

dvbpsi_descriptor_t *

p_descriptor

)

"VBI data" descriptor decoder.

Parameters

p_descriptor

pointer to the descriptor structure

Returns

a pointer to a new "VBI data" descriptor structure which contains the decoded data.

dvbpsi_descriptor_t * dvbpsi_GenVBIDataDr	(	dvbpsi_vbi_dr_t *	p_decoded,
		bool	b_duplicate
	)

"VBI data" descriptor generator.

Parameters

p_decoded	pointer to a decoded "VBI data" descriptor structure
b_duplicate	if true then duplicate the p_decoded structure into the descriptor

Returns

a pointer to a new descriptor structure which contains encoded data.
