[out] Pointer to a variable of type long that receives the transport stream ID.

This property is not required for tuning. It will be set by the BDA Transport Information Filter (TIF) when the signal is acquired. This property is not used by the application but may be used by one or more of the receiver filters. For example, a TIF may use this to determine whether the transport stream has changed from what was originally tuned and generate events that cause re-acquisition of the requested program.
