Detailed Description

Encapsulates data about ATSC stream and emits events for most tables.

Constructor & Destructor Documentation

ATSCStreamData::ATSCStreamData ( int  desiredMajorChannel,
int  desiredMinorChannel,
bool  cacheTables = false 
)

Initializes ATSCStreamData.

This adds the PID of the PAT and ATSC PSIP tables to "_pids_listening"

Parameters:
desiredMajorChannelIf you want rewritten PAT and PMTs for a desired channel set this to a value greater than zero.
desiredMinorChannelIf you want rewritten PAT and PMTs for a desired channel set this to a value greater than zero.
cacheTablesIf true important tables will be cached.

bool ATSCStreamData::IsRedundant ( uint  pid,

Returns true if table already seen.

Todo:

All RRT tables are ignored

We don't check the start time of EIT and ETT tables in the version check, so many tables are improperly ignored.
