Member Function Documentation

void FirewireSignalMonitor::HandlePAT ( const ProgramAssociationTable * pat ) [virtual]

Reimplemented from DTVSignalMonitor.

Definition at line 93 of file firewiresignalmonitor.cpp.

void FirewireSignalMonitor::HandlePMT	(	uint	pnum,
		const ProgramMapTable *	pmt
	)			`[virtual]`

Reimplemented from DTVSignalMonitor.

Definition at line 117 of file firewiresignalmonitor.cpp.

void FirewireSignalMonitor::Stop ( void ) [virtual]

Stop signal monitoring and table monitoring threads.

Reimplemented from SignalMonitor.

Definition at line 81 of file firewiresignalmonitor.cpp.

Referenced by deleteLater(), and ~FirewireSignalMonitor().

void FirewireSignalMonitor::deleteLater ( void ) [virtual, slot]

Safer alternative to just deleting signal monitor directly.

Reimplemented from DTVSignalMonitor.

Definition at line 71 of file firewiresignalmonitor.cpp.

void FirewireSignalMonitor::UpdateValues ( void ) [protected, virtual]

Fills in frontend stats and emits status Qt signals.

This function uses five ioctl's FE_READ_SNR, FE_READ_SIGNAL_STRENGTH FE_READ_BER, FE_READ_UNCORRECTED_BLOCKS, and FE_READ_STATUS to obtain statistics from the frontend.

This is automatically called by MonitorLoop(), after Start() has been used to start the signal monitoring thread.

Reimplemented from SignalMonitor.

Definition at line 193 of file firewiresignalmonitor.cpp.

void FirewireSignalMonitor::EmitFirewireSignals ( void ) [protected]

Emits signals for lock, signal strength, etc.

Definition at line 304 of file firewiresignalmonitor.cpp.

Referenced by UpdateValues().

void * FirewireSignalMonitor::TableMonitorThread ( void * param ) [static, protected]

Definition at line 133 of file firewiresignalmonitor.cpp.

Referenced by UpdateValues().

void FirewireSignalMonitor::RunTableMonitor ( void ) [protected]

Definition at line 140 of file firewiresignalmonitor.cpp.
