		uint8_t	i_table_id,
		uint16_t	i_extension,
		dvbpsi_atsc_mgt_callback	pf_callback,
		void *	p_cb_data
	)

Creation and initialization of a MGT decoder.

Parameters

p_dvbpsi	dvbpsi handle to Subtable demultiplexor to which the decoder is attached
i_table_id	Table ID, 0xC7.
i_extension	Table ID extension, here 0x0000.
pf_callback	function to call back on new MGT.
p_cb_data	private data given in argument to the callback.

Returns

true if everything went ok, false otherwise
