Scenario 2

 

In this scenario we examine average playout rates and underflow probabilities for long programs streamed at the maximum available bandwidth of the channel. As in scenario 1, we compute the transition matrix P. Now, however, we assume that when the buffer underflows, playout halts and begins again after the client refills the buffer to the target level. Thus

  equation217

Next, we simply find the stationary distribution, tex2html_wrap_inline1025 of the transition matrix P or tex2html_wrap_inline1029 . The underflow probability is given as tex2html_wrap_inline1031 and the average playout rate, tex2html_wrap_inline1019 is calculated as:
