Function Documentation

bool dvbpsi_atsc_AttachSTT	(	dvbpsi_t *	p_dvbpsi,
		uint8_t	i_table_id,
		uint16_t	i_extension,
		dvbpsi_atsc_stt_callback	pf_stt_callback,
		void *	p_cb_data
	)

Creation and initialization of a STT 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, here it should be 0.
pf_stt_callback	function to call back on new STT.
p_cb_data	private data given in argument to the callback.

Returns

true if everything went ok else false

dvbpsi_atsc_DeleteSTT

(

dvbpsi_atsc_stt_t *

p_stt

)

Clean and free a dvbpsi_atsc_stt_t structure.

Parameters

p_stt

pointer to the STT structure

Returns

nothing.

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

Destroy a STT decoder.

Parameters

p_dvbpsi	dvbpsi handle to Subtable demultiplexor to which the decoder is attached.
i_table_id	Table ID, 0xCD.
i_extension	Table extension, ignored as this should always be 0. (Required to match prototype for demux)

Returns

nothing.

void dvbpsi_atsc_EmptySTT

(

dvbpsi_atsc_stt_t *

p_stt

)

Clean a dvbpsi_atsc_stt_t structure.

Parameters

p_stt

pointer to the STT structure

Returns

nothing.

void dvbpsi_atsc_InitSTT	(	dvbpsi_atsc_stt_t *	p_stt,
		uint8_t	i_table_id,
		uint16_t	i_extension,
		uint8_t	i_protocol,
		bool	b_current_next
	)

Initialize a user-allocated dvbpsi_atsc_stt_t structure.

Parameters

p_stt	pointer to the STT structure
i_table_id	Table ID, 0xCD.
i_extension	Table extension, ignored as this should always be 0.
i_protocol	PSIP Protocol version.
b_current_next	current next indicator

Returns

nothing.

dvbpsi_atsc_stt_t * dvbpsi_atsc_NewSTT	(	uint8_t	i_table_id,
		uint16_t	i_extension,
		uint8_t	i_version,
		bool	b_current_next
	)

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

Parameters

i_table_id	Table ID, 0xCD.
i_extension	Table extension, ignored as this should always be 0.
i_version	PSIP Protocol version.
b_current_next	current next indicator

Returns

p_stt pointer to the STT structure
