Recall the simple model for HTTP streaming shown in Figure 7.3. Recall that B denotes the size of the client’s application buffer, and Q denotes the number of bits that must be buffered before the client application begins playout. Also r denotes the video consumption rate. Assume that the server sends bits at a constant rate x whenever the client buffer is not full.
a. Suppose that x < r.="" as="" discussed="" in="" the="" text,="" in="" this="" case="" playout="" will="" alternate="" between="" periods="" of="" continuous="" playout="" and="" periods="" of="" freezing.="" determine="" the="" length="" of="" each="" continuous="" playout="" and="" freezing="" period="" as="" a="" function="" of="" q,="" r,="" and="">
b. Now suppose that x > r. At what time does the client application buffer become full?
