struct dvb_desc * descriptor
struct atsc_table_eit_event * next
struct tm start
uint16_t source_id
Detailed Description
ATSC EIT event table.
- Parameters
event_id an uniquelly (inside a service ID) event ID
title_length title length. Zero means no title
duration duration in seconds
etm Extended Text Message location
descriptor pointer to struct dvb_desc
next pointer to struct atsc_table_eit_event
start event start (in struct tm format)
source_id source id (obtained from ATSC header)
This structure is used to store the original ATSC EIT event table, converting the integer fields to the CPU endianness, and converting the timestamps to a way that it is better handled on Linux.
The undocumented parameters are used only internally by the API and/or are fields that are reserved. They shouldn't be used, as they may change on future API releases.
Everything after atsc_table_eit_event::descriptor (including it) won't be bit-mapped to the data parsed from the MPEG TS. So, metadata are added there.
