Typedef Documentation

struct dvbpsi_atsc_ett_s dvbpsi_atsc_ett_t

dvbpsi_atsc_ett_t type definition.

This structure is used to store a decoded ETT. (ATSC document A/56-2009, section 6.6.)

Function Documentation

bool dvbpsi_atsc_AttachETT	(	dvbpsi_t *	p_dvbpsi,
		uint8_t	i_table_id,
		uint16_t	i_extension,
		dvbpsi_atsc_ett_callback	pf_callback,
		void *	p_cb_data
	)

Creation and initialization of a ETT decoder.

Parameters

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

Returns

true if everything went ok, else it returns false.

void dvbpsi_atsc_DeleteETT

(

dvbpsi_atsc_ett_t *

p_ett

)

Clean and free a dvbpsi_atsc_ett_t structure.

Parameters

p_ett

pointer to the ETT structure

Returns

nothing.

void dvbpsi_atsc_DetachETT	(	dvbpsi_t *	p_dvbpsi,
		uint8_t	i_table_id,
		uint16_t	i_extension
	)

Destroy a ETT decoder.

Parameters

p_dvbpsi	dvbpsi handle to Subtable demultiplexor to which the decoder is attached
i_table_id	Table ID, 0xCD.
i_extension	Table ID extension, normally 0x0000.

Returns

nothing.

void dvbpsi_atsc_EmptyETT

(

dvbpsi_atsc_ett_t *

p_ett

)

Clean a dvbpsi_atsc_ett_t structure.

Parameters

p_ett

pointer to the ETT structure

Returns

nothing.

void dvbpsi_atsc_InitETT	(	dvbpsi_atsc_ett_t *	p_ett,
		uint8_t	i_table_id,
		uint16_t	i_extension,
		uint8_t	i_version,
		uint8_t	i_protocol,
		uint32_t	i_etm_id,
		bool	b_current_next
	)

Initialize a user-allocated dvbpsi_atsc_ett_t structure.

Parameters

p_ett	pointer to the ETT structure
i_table_id	Table ID, 0xCC.
i_extension	Table ID extension, normally 0x0000.
i_version	version
i_protocol	PSIP Protocol version.
i_etm_id	ETM Identifier.
b_current_next	current next indicator

Returns

nothing.

dvbpsi_atsc_ett_t * dvbpsi_atsc_NewETT	(	uint8_t	i_table_id,
		uint16_t	i_extension,
		uint8_t	i_version,
		uint8_t	i_protocol,
		uint32_t	i_etm_id,
		bool	b_current_next
	)

Allocate and initialize a new dvbpsi_atsc_ett_t structure. Use ObjectRefDec to delete it.

Parameters

i_table_id	Table ID, 0xCC.
i_extension	Table ID extension, normally 0x0000.
i_version	version
i_protocol	PSIP Protocol version.
i_etm_id	ETM Identifier.
b_current_next	current next indicator

Returns

p_ett pointer to the ETT structure, NULL otherwise
