Public Member Functions
void	RetuneMonitor (void)
bool	IsRetuneAllowed (void) const
void	SetRetuneAllowed (bool allow, DTVSignalMonitor sigmon, DVBChannel dvbchan)
Static Public Member Functions
static DVBStreamHandler *	Get (const QString &dvb_device)

Private Member Functions
	DVBStreamHandler (const QString &)
virtual void	run (void)
	Runs the Qt event loop unless we have a QRunnable, in which case we run the runnable run instead.
void	RunTS (void)
	Uses TS filtering devices to read a DVB device for tables & data.
void	RunSR (void)
	Uses "Section" reader to read a DVB device for tables.
virtual void	CycleFiltersByPriority (void)
bool	SupportsTSMonitoring (void)
	Returns true if TS monitoring is supported.
virtual PIDInfo *	CreatePIDInfo (uint pid, uint stream_type, int pes_type)
virtual void	SetRunningDesired (bool desired)
	At minimum this sets _running_desired, this may also send signals to anything that might be blocking the run() loop.

void DVBStreamHandler::run ( void ) [private, virtual]

Runs the Qt event loop unless we have a QRunnable, in which case we run the runnable run instead.

Note:: If you override this method you must call RunProlog before you do any work and RunEpilog before you exit the run method.

Reimplemented from MThread.

Definition at line 104 of file dvbstreamhandler.cpp.

void DVBStreamHandler::RunTS ( void ) [private]

Uses TS filtering devices to read a DVB device for tables & data.

This supports all types of MPEG based stream data, but is extreemely slow with DVB over USB 1.0 devices which for efficiency reasons buffer a stream until a full block transfer buffer full of the requested tables is available. This takes a very long time when you are just waiting for a PAT or PMT table, and the buffer is hundreds of packets in size.

void DVBStreamHandler::RunSR ( void ) [private]

Uses "Section" reader to read a DVB device for tables.

This currently only supports DVB streams, ATSC and the raw MPEG streams used by some cable and satelite providers is not supported.

Definition at line 295 of file dvbstreamhandler.cpp.

Referenced by run().

void DVBStreamHandler::CycleFiltersByPriority ( void ) [private, virtual]

Reimplemented from StreamHandler.

Definition at line 379 of file dvbstreamhandler.cpp.

bool DVBStreamHandler::SupportsTSMonitoring ( void ) [private]

Returns true if TS monitoring is supported.

NOTE: If you are using a DEC2000-t device you need to apply the patches provided by Peter Beutner for it, see http://www.gossamer-threads.com/lists/mythtv/dev/166172 These patches should make it in to Linux 2.6.15 or 2.6.16.
