Detailed Description
Decode PSIP Extented Text Table (ATSC ETT).
- Author:
- Adam Charrett
Typedef Documentation
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
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.
Clean and free a dvbpsi_atsc_ett_t structure.
- Parameters:
-
| p_ett | pointer to the ETT structure |
- Returns:
- nothing.
