◆ Start()

int cPipHandler::Start ( int  channelNum)
private

Create a new pip receiver and render the pip stream.

Parameters
channelNumnumber of the channel to be switched to 0 switches to the current main stream channel
Return values
0pip was enabled
-1pip wasn't enabled, no device for channel available

◆ Stop()

void cPipHandler::Stop ( void  )
private
