Function Documentation

dvbpsi_vbi_dr_t * dvbpsi_DecodeVBIDataDr ( dvbpsi_descriptor_t p_descriptor)

"VBI data" descriptor decoder.

Parameters
p_descriptorpointer 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_decodedpointer to a decoded "VBI data" descriptor structure
b_duplicateif true then duplicate the p_decoded structure into the descriptor
Returns
a pointer to a new descriptor structure which contains encoded data.
