Application interface for the PAT decoder and the PAT generator. New decoded PAT tables are sent by callback to the application.

Function Documentation

dvbpsi_pat_delete()

void dvbpsi_pat_delete

(

dvbpsi_pat_t *

p_pat

)

Clean and free a dvbpsi_pat_t structure.

Parameters

p_pat

pointer to the PAT structure

Returns

nothing.

dvbpsi_pat_detach()

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

Destroy a PAT decoder.

Parameters

p_dvbpsi	pointer to dvbpsi_t handle
i_table_id	Table ID
i_extension	Table ID extension

Returns

nothing.

The handle isn't valid any more.

dvbpsi_pat_empty()

void dvbpsi_pat_empty

(

dvbpsi_pat_t *

p_pat

)

Clean a dvbpsi_pat_t structure.

Parameters

p_pat

pointer to the PAT structure

Returns

nothing.

dvbpsi_pat_init()

void dvbpsi_pat_init	(	dvbpsi_pat_t *	p_pat,
		uint16_t	i_ts_id,
		uint8_t	i_version,
		bool	b_current_next
	)

Initialize a user-allocated dvbpsi_pat_t structure.

Parameters

p_pat	pointer to the PAT structure
i_ts_id	transport stream ID
i_version	PAT version
b_current_next	current next indicator

Returns

nothing.

dvbpsi_pat_new()

dvbpsi_pat_t * dvbpsi_pat_new	(	uint16_t	i_ts_id,
		uint8_t	i_version,
		bool	b_current_next
	)

Allocate and initialize a new dvbpsi_pat_t structure.

Parameters

i_ts_id	transport stream ID
i_version	PAT version
b_current_next	current next indicator

Returns

p_pat pointer to the PAT structure

dvbpsi_pat_program_add()

dvbpsi_pat_program_t * dvbpsi_pat_program_add	(	dvbpsi_pat_t *	p_pat,
		uint16_t	i_number,
		uint16_t	i_pid
	)

Add a program at the end of the PAT.

Parameters

p_pat	pointer to the PAT structure
i_number	program number
i_pid	PID of the NIT/PMT

Returns

a pointer to the added program.
