Member Function Documentation

bool HDHRChannel::Open ( void ) [virtual]

Opens the channel changing hardware for use.

Implements ChannelBase.

Definition at line 55 of file hdhrchannel.cpp.

void HDHRChannel::Close ( void ) [virtual]

Closes the channel changing hardware to use.

Implements ChannelBase.

Definition at line 77 of file hdhrchannel.cpp.

Referenced by Open(), and ~HDHRChannel().

bool HDHRChannel::EnterPowerSavingMode ( void ) [virtual]

Enters power saving mode if the card supports it.

Reimplemented from DTVChannel.

Definition at line 87 of file hdhrchannel.cpp.

bool HDHRChannel::IsOpen ( void ) const [virtual]

Reports whether channel is already open.

Implements ChannelBase.

Definition at line 95 of file hdhrchannel.cpp.

Referenced by Close(), EnterPowerSavingMode(), and Open().

QString HDHRChannel::GetDevice ( void ) const [inline, virtual]

Returns String representing device, useful for debugging.

Reimplemented from ChannelBase.

Definition at line 35 of file hdhrchannel.h.

Referenced by HDHRSignalMonitor::HDHRSignalMonitor(), and HDHRRecorder::Open().

virtual vector<DTVTunerType> HDHRChannel::GetTunerTypes ( void ) const [inline, virtual]

Returns a vector of supported tuning types.

Reimplemented from DTVChannel.

Definition at line 36 of file hdhrchannel.h.

bool HDHRChannel::IsMaster ( void ) const [virtual]

Returns true if this is the first of a number of multi-rec devs.

Reimplemented from DTVChannel.

Definition at line 47 of file hdhrchannel.cpp.

bool HDHRChannel::SetChannelByString ( const QString & channum ) [virtual]

Reimplemented from DTVChannel.

Definition at line 181 of file hdhrchannel.cpp.

bool HDHRChannel::Tune	(	const DTVMultiplex &	tuning,
		QString	inputname
	)			`[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.
