Abstract
According to embodiments, an enhancement layer segment may be requested in addition to a base layer segment for a same video. The enhancement layer may be requested, in a low priority, so that the base layer may be delivered in priority. If the enhancement layer can be obtained by a deadline, a subsequent base layer segment may be requested at a higher quality (e.g., at a bitrate lower than or equal to the sum of the bitrates of the previously requested base layer and enhancement layer segments). If, for example, at a playback time, the enhancement layer segment is not obtained, it may be determined that the quality cannot be increased and subsequent requests for enhancement layer segments may be cancelled (e.g., not transmitted). According to embodiments, probing may repeat (e.g., any of immediately, regularly, periodically, . . . ) to detect available bandwidth variations.
