Adapting the position-based stream measurement to event-based measurement.
To adapt the standard position based stream measurement to an event-based model an adapter can be used to negotiate between the different models. The adapter allows to the event-based left side (the client side) to signal events like Start and Stop and mediates these events to stream positions at the right side. The mediation is simply done by increasing a simulated stream position internally using a timer for all states where the stream is playing (after the Start event etc).
