Member Function Documentation

bool FirewireChannel::Open ( void ) [virtual]

Opens the channel changing hardware for use.

Implements ChannelBase.

Definition at line 47 of file firewirechannel.cpp.

void FirewireChannel::Close ( void ) [virtual]

Closes the channel changing hardware to use.

Implements ChannelBase.

Definition at line 81 of file firewirechannel.cpp.

virtual bool FirewireChannel::Tune	(	const DTVMultiplex &	tuning,
		QString	inputname
	)			`[inline, virtual]`

This performs the actual frequency tuning and in some cases input switching.

In rare cases such as ASI this does nothing since all the channels are in the same MPTS stream on the same input. But generally you will need to implement this when adding support for new hardware.

Implements DTVChannel.

Definition at line 28 of file firewirechannel.h.

Referenced by Retune().

bool FirewireChannel::Tune	(	const QString &	freqid,
		int	finetune
	)			`[virtual]`

This tunes on the frequency Identification parameter for hardware that supports it.

This is only called when there is no frequency set. This is used to implement "Channel Numbers" in analog tuning scenarios and to implement "Virtual Channels" in the OCUR and Firewire tuners.

Reimplemented from DTVChannel.

Definition at line 143 of file firewirechannel.cpp.

bool FirewireChannel::Retune ( void ) [virtual]

Reimplemented from ChannelBase.

Definition at line 122 of file firewirechannel.cpp.

Referenced by FirewireSignalMonitor::UpdateValues().

bool FirewireChannel::SetPowerState ( bool on ) [virtual]

Definition at line 96 of file firewirechannel.cpp.

Referenced by FirewireSignalMonitor::UpdateValues().

virtual bool FirewireChannel::IsOpen ( void ) const [inline, virtual]

Reports whether channel is already open.

Implements ChannelBase.
