ProcessDownloadServerInitiate()

void Dsmcc::ProcessDownloadServerInitiate ( const unsigned char *  data, int  length  )

protected

Process a DSI message.

This may contain service gateway info. In the UK it is often the case that an object carousel is shared between different services. One PID carries all the messages for these services and the only difference is that a service-specific PID carries DSI messages identifying the root to be used for that service.
