    2020 * Policy 3:  When the buffer is less than 30% full, the perceived available bitrate is equal to half of the actual bitrate observed over the download of the last segment.

     22These policies involve a tradeoff between video rate and buffer status. Obviously, we want to download segments of a high video rate, because these offer better quality. However, we also want to avoid freezes (the state where there is zero video in the buffer) and we want the video playback to be smooth, avoiding big jumps in video rate. We will use the WiMAX testbed to see how this tradeoff works to deliver DASH video over a wireless network.

    2225These experiments will be conducted in a cellular environment using the WiMAX Base Station and nodes on the {{{outdoor}}} testbed at WINLAB. The experiment scenario is as follows:
