/********************************************************************************
* TvCtrlPointStart
*
* Description:
* Call this function to initialize the UPnP library and start the TV Control
* Point. This function creates a timer thread and provides a callback
* handler to process any UPnP events that are received.
*
* Parameters:
* None
*
* Returns:
* TV_SUCCESS if everything went well, else TV_ERROR
*
