To verify whether such playback list updatesmay always prohibit
the device’s power level from dropping, we have further conducted tests by creating a live broadcast stream from the same flash video and deploy it on CloudMoV.
We find that regardless of the burst transmission intervals we set, the device’s
power level does not drop due to frequent play list update in a
live streaming.
We omit the plots of the results since they are similar to the red curve in Fig. 8. Different browsers may configure different update frequencies, since the value is not specified in the HTTP Live Streaming protocol.
This value should be carefully set, for potentially increasing battery lifetime at the
mobile users.
