Member Function Documentation

◆ Open()

bool IPTVChannel::Open ( void  )
overridevirtual

Opens the channel changing hardware for use.

Implements ChannelBase.

Definition at line 36 of file iptvchannel.cpp.

Referenced by IPTVRecorder::Open().

◆ Tune() [1/7]

bool IPTVChannel::Tune ( const IPTVTuningData ,
bool   
)
overridevirtual

Performs IPTV Tuning. Only implemented by IPTVChannel.

Reimplemented from DTVChannel.

Definition at line 161 of file iptvchannel.cpp.

◆ Tune() [2/7]

bool IPTVChannel::Tune ( const DTVMultiplex tuning)
inlineoverridevirtual

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 38 of file iptvchannel.h.

◆ SetStreamData()

void IPTVChannel::SetStreamData ( MPEGStreamData sd)

◆ IsOpen()

bool IPTVChannel::IsOpen ( void  ) const
overridevirtual

Reports whether channel is already open.

Implements ChannelBase.

Definition at line 150 of file iptvchannel.cpp.

Referenced by IPTVRecorder::IsOpen(), and Open().

◆ GetDevice()

QString IPTVChannel::GetDevice ( void  ) const
inlineoverridevirtual

Returns String representing device, useful for debugging.

Reimplemented from ChannelBase.

Definition at line 46 of file iptvchannel.h.

◆ GetStreamHandler()

overrideprotectedvirtual

Closes the channel changing hardware to use.

Implements ChannelBase.

Definition at line 85 of file iptvchannel.cpp.

Referenced by IPTVRecorder::Close(), Open(), and ~IPTVChannel().

◆ EnterPowerSavingMode()

bool IPTVChannel::EnterPowerSavingMode ( void  )
overrideprotectedvirtual

Enters power saving mode if the card supports it.

Reimplemented from DTVChannel.

Definition at line 91 of file iptvchannel.cpp.

◆ IsExternalChannelChangeSupported()

bool IPTVChannel::IsExternalChannelChangeSupported ( void  )
inlineoverrideprotectedvirtual

Reimplemented from ChannelBase.

◆ CloseStreamHandler()

void IPTVChannel::CloseStreamHandler ( void  )
private

Definition at line 116 of file iptvchannel.cpp.

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

◆ 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 59 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 64 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.
