Function Documentation

bool dvbpsi_atsc_AttachVCT	(	dvbpsi_t *	p_dvbpsi,
		uint8_t	i_table_id,
		uint16_t	i_extension,
		dvbpsi_atsc_vct_callback	pf_vct_callback,
		void *	p_cb_data

Creation and initialization of a VCT decoder.

Parameters

p_dvbpsi	dvbpsi handle to Subtable demultiplexor to which the decoder is attached.
i_table_id	Table ID, 0xC8 or 0xC9.
i_extension	Table ID extension, here TS ID.
pf_vct_callback	function to call back on new VCT.
p_cb_data	private data given in argument to the callback.

Returns

true if everything went ok, else false.
