Start()

int cPipHandler::Start ( int  channelNum )

private

Create a new pip receiver and render the pip stream.

Parameters

channelNum

number of the channel to be switched to 0 switches to the current main stream channel

Return values

0	pip was enabled
-1	pip wasn't enabled, no device for channel available

Stop()

void cPipHandler::Stop ( void  )

private
