1. A method comprising:
requesting an initial base layer segment encoded at a first base layer bitrate and an initial enhancement layer segment encoded at a first enhancement layer bitrate, wherein the initial base layer segment and the initial enhancement layer segment correspond to a same temporal portion of a video, and wherein receiving the initial enhancement layer segment is used for probing for available bandwidth;
probing for available bandwidth by determining whether the initial enhancement layer segment is received in time with the initial base layer segment for uninterrupted playout; and
requesting a subsequent base layer segment of a subsequent portion of the video at a second base layer bitrate that is higher than the first base layer bitrate, wherein the second base layer bitrate is less than or equal to a sum of the first enhancement layer bitrate and the first base layer bitrate, wherein the subsequent base layer segment is requested at the second base layer bitrate based on a determination that the initial enhancement layer segment is received with the initial base layer segment for an uninterrupted playout.
