Constructor & Destructor Documentation

FirewireSignalMonitor::FirewireSignalMonitor	(	int	db_cardnum,
		FirewireChannel *	_channel,
		uint64_t	_flags = `kFWSigMon_WaitForPower`
	)

Initializes signal lock and signal values.

Start() must be called to actually begin continuous signal monitoring. The timeout is set to 3 seconds, and the signal threshold is initialized to 0%.

Parameters:

	db_cardnum	Recorder number to monitor, if this is less than 0, SIGNAL events will not be sent to the frontend even if SetNotifyFrontend(true) is called.
	_channel	FirewireChannel for card
	_flags	Flags to start with

Member Function Documentation

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

Reimplemented from DTVSignalMonitor.

Definition at line 92 of file firewiresignalmonitor.cpp.

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

Reimplemented from DTVSignalMonitor.

Definition at line 119 of file firewiresignalmonitor.cpp.

void FirewireSignalMonitor::Stop ( void ) [virtual]

Stop signal monitoring and table monitoring threads.

Reimplemented from SignalMonitor.

Definition at line 78 of file firewiresignalmonitor.cpp.

Referenced by ~FirewireSignalMonitor().

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 run(), after Start() has been used to start the signal monitoring thread.

Reimplemented from SignalMonitor.
