◆ Open()

bool FirewireChannel::Open ( void )

overridevirtual

Opens the channel changing hardware for use.

Implements ChannelBase.

Definition at line 47 of file firewirechannel.cpp.

◆ Close()

void FirewireChannel::Close ( void )

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

Performs IPTV Tuning. Only implemented by IPTVChannel.
