Some drivers report the actual ratio, while others report the dB, but in this case some weak signals may report a very high S/N since negative dB are not supported by MythTV or the 4.0 version of the DVB API due to the large number of drivers that ignored the fact that this was a signed number in the 3.0 API.

bool DVBChannel::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.

bool DVBChannel::Tune	(	const DTVMultiplex &	tuning,
		uint	inputid,
		bool	force_reset = `false`,
		bool	same_input = `false`
	)

Tunes the card to a frequency but does not deal with PIDs.

This is used by DVB Channel Scanner, the EIT Parser, and by TVRec.

Parameters

tuning	Info on transport to tune to
inputid	Optional, forces specific input (for DiSEqC)
force_reset	If true, frequency tuning is done even if it should not be needed.
same_input	Optional, doesn't change input (for retuning).
