Метод	Описание
CancelTune ( ) : void	cancels the tune
GetStreamQualityCounters ( int &totalBytes, int &discontinuityCounter ) : void	Fetches the stream quality information
OnAfterTune ( ) : void	Should be called when the graph is tuned to the new channel resets the state
OnBeforeTune ( ) : void	Should be called before tuning to a new channel resets the state
OnCaReceived ( ) : int	Called when tswriter.ax has received a new ca section
OnGraphStart ( ) : void	Should be called when the graph is about to start Resets the state If graph is already running, starts the pmt grabber to grab the pmt for the new channel
OnGraphStarted ( ) : void	Should be called when the graph has been started. Sets up the PMT grabber to grab the PMT of the channel when the graph hasn't been running previously
OnGraphStop ( ) : void	Should be called when graph is about to stop. stops any timeshifting/recording on this channel
OnGraphStopped ( ) : void	should be called when graph has been stopped Resets the graph state
OnPMTReceived ( int pmtPid ) : int	Called when tswriter.ax has received a new pmt
TvDvbChannel ( ) : System	Initializes a new instance of the TvDvbChannel class.
TvDvbChannel ( IFilterGraph2 graphBuilder, TvLibrary.Implementations.DVB.ConditionalAccess ca, TvLibrary.Implementations.DVB.MDPlugs mdplugs, IBaseFilter tif, IBaseFilter tsWriter, int subChannelId, IChannel channel ) : System	Initializes a new instance of the TvDvbChannel class.
