Function Documentation

void dvbpsi_Demux	(	dvbpsi_handle	h_dvbpsi,
		dvbpsi_psi_section_t *	p_section
	)

Sends the PSI sections to the right subtable decoder according to their table ID and extension.

Parameters:

	h_dvbpsi	PSI decoder handle.
	p_section	PSI section.

dvbpsi_demux_subdec_t * dvbpsi_demuxGetSubDec	(	dvbpsi_demux_t *	p_demux,
		uint8_t	i_table_id,
		uint16_t	i_extension
	)

Looks for a subtable decoder, given the subtable ID.

Parameters:

	p_demux	Pointer to the demux structure.
	i_table_id	Table ID of the wanted subtable.
	i_extension	Table ID extension of the wanted subtable.

Returns:

a pointer to the found subdecoder, or NULL.

void dvbpsi_DetachDemux

(

dvbpsi_handle

h_dvbpsi

)

Destroys a demux structure.

Parameters:

h_dvbpsi

The handle of the demux to be destroyed.
