◆ Open()

bool HDHRChannel::Open ( void )

overridevirtual

Opens the channel changing hardware for use.

Implements ChannelBase.

QString HDHRChannel::GetDevice ( void ) const

inlineoverridevirtual

Returns String representing device, useful for debugging.

◆ GetTunerTypes()

std::vector<DTVTunerType> HDHRChannel::GetTunerTypes ( void ) const

inlineoverridevirtual

Returns a vector of supported tuning types.

Reimplemented from DTVChannel.

Definition at line 37 of file hdhrchannel.h.

bool HDHRChannel::IsMaster ( void ) const

overridevirtual

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

bool HDHRChannel::SetChannelByString ( const QString & channum )

overridevirtual

Reimplemented from DTVChannel.

Definition at line 183 of file hdhrchannel.cpp.

◆ Tune() [1/7]

bool HDHRChannel::Tune ( const DTVMultiplex & tuning )

overridevirtual

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 167 of file hdhrchannel.cpp.

◆ Tune() [2/7]

bool HDHRChannel::Tune	(	const QString &	freqid,
		int
	)

overridevirtual

This is used when the tuner type is kTunerTypeOCUR.

Reimplemented from ChannelBase.

Definition at line 99 of file hdhrchannel.cpp.

◆ Tune() [3/7]

virtual bool DTVChannel::Tune

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.

◆ Tune() [4/7]

virtual bool DTVChannel::Tune

inline

Performs IPTV Tuning. Only implemented by IPTVChannel.

Definition at line 58 of file dtvchannel.h.

◆ Tune() [5/7]

virtual bool DTVChannel::Tune

inline

Leave it up to the implementation to map the channnum appropriately.

Used by the ExternalRecorder.

Definition at line 63 of file dtvchannel.h.

◆ Tune() [6/7]

bool DTVChannel::Tune

inlineoverride

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.

Definition at line 75 of file dtvchannel.h.

◆ Tune() [7/7]

virtual bool DTVChannel::Tune
