bool cPatPmtParser::GetVersions ( int &  PatVersion,
int &  PmtVersion 
) const

Returns true if a valid PAT/PMT has been parsed and stores the current version numbers in the given variables.

bool cPatPmtParser::IsPmtPid ( int  Pid) const

Returns true if Pid the one of the PMT pids as defined by the current PAT.

If no PAT has been received yet, false will be returned.

void cPatPmtParser::ParsePat ( const uchar Data,
int  Length 
)
bool cPatPmtParser::ParsePatPmt ( const uchar Data,
int  Length 
)

Parses the given Data (which may consist of several TS packets, typically an entire frame) and extracts the PAT and PMT.

Returns true if a valid PAT/PMT has been detected.

void cPatPmtParser::ParsePmt ( const uchar Data,
int  Length 
)

Parses the PMT data from the single TS packet in Data.

Length is always TS_SIZE. The PMT may consist of several TS packets, which are delivered to the parser through several subsequent calls to ParsePmt(). The whole PMT data will be processed once the last packet has been received.
