Author

Arnaud de Bossoreille de Ribou bozo@.nosp@m.via..nosp@m.ecp.f.nosp@m.r Application interface for the PAT decoder and the PAT generator. New decoded PAT tables are sent by callback to the application.

Function Documentation

bool dvbpsi_pat_attach	(	dvbpsi_t *	p_dvbpsi,
		dvbpsi_pat_callback	pf_callback,
		void *	p_cb_data
	)

Creation and initialization of a PAT decoder. The decoder will be attached to 'p_dvbpsi' argument.

Parameters

p_dvbpsi	handle to dvbpsi with attached decoder
pf_callback	function to call back on new PAT
p_cb_data	private data given in argument to the callback

Returns

true on success, false on failure

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.

void dvbpsi_pat_detach

(

dvbpsi_t *

p_dvbpsi

)

Destroy a PAT decoder.

Parameters

p_dvbpsi

pointer to dvbpsi_t handle

Returns

nothing.

The handle isn't valid any more.

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.

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_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_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.

dvbpsi_psi_section_t * dvbpsi_pat_sections_generate	(	dvbpsi_t *	p_dvbpsi,
		dvbpsi_pat_t *	p_pat,
		int	i_max_pps
	)

PAT generator.

Parameters

p_dvbpsi	handle to dvbpsi with attached decoder
p_pat	pointer to the PAT structure
i_max_pps	limitation of the number of program in each section (max: 253).

Returns

a pointer to the list of generated PSI sections.

Generate PAT sections based on the dvbpsi_pat_t structure.
