Detailed Description

Application interface for the PAT decoder and the PAT generator.

>

Author:

Arnaud de Bossoreille de Ribou <bozo@via.ecp.fr>

Application interface for the PAT decoder and the PAT generator. New decoded PAT tables are sent by callback to the application. If a table wasn't active (b_current_next == 0) and the next is the same but active (b_current_next == 1) then the program list is empty and should be caught from the previous structure.

Define Documentation

#define dvbpsi_DeletePAT (  p_pat   )

Value: do { \ dvbpsi_EmptyPAT(p_pat); \ free(p_pat); \ } while(0); Clean and free a dvbpsi_pat_t structure. Parameters: p_pat  pointer to the PAT structure Returns: nothing.

#define dvbpsi_NewPAT (  p_pat, i_ts_id, i_version, b_current_next   )

Value: do { \ p_pat = (dvbpsi_pat_t*)malloc(sizeof(dvbpsi_pat_t)); \ if(p_pat != NULL) \ dvbpsi_InitPAT(p_pat, i_ts_id, i_version, b_current_next); \ } while(0); Allocate and initialize a new 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.

Function Documentation

dvbpsi_handle dvbpsi_AttachPAT (  dvbpsi_pat_callback  pf_callback, void *  p_cb_data )

Creation and initialization of a PAT decoder. Parameters: pf_callback  function to call back on new PAT p_cb_data  private data given in argument to the callback Returns: a pointer to the decoder for future calls.

void dvbpsi_DetachPAT (  dvbpsi_handle  h_dvbpsi  )

Destroy a PAT decoder. Parameters: h_dvbpsi  handle to the decoder Returns: nothing. The handle isn't valid any more.

void dvbpsi_EmptyPAT (  dvbpsi_pat_t *  p_pat  )

Clean a dvbpsi_pat_t structure. Parameters: p_pat  pointer to the PAT structure Returns: nothing.

dvbpsi_psi_section_t * dvbpsi_GenPATSections (  dvbpsi_pat_t *  p_pat, int  i_max_pps )

PAT generator. Parameters: 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.

void dvbpsi_InitPAT (  dvbpsi_pat_t *  p_pat, uint16_t  i_ts_id, uint8_t  i_version, int  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_program_t * dvbpsi_PATAddProgram (  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.
