Abstract
Techniques for estimation of bandwidth for transfer of video content in chunked transfer mode are described herein. A number of chunk samples may be collected during video content transmission. For each chunk sample, its respective delivery speed may be compared to its respective encoding bitrate. If the delivery speed is greater than or equal to the encoding bitrate, then the chunk sample may be included in a primary set of chunk samples. The primary set of chunk samples may be clustered into a lower speed cluster and a higher speed cluster. A representative speed, such as an average or weighted average speed, of the delivery speeds of the chunk samples in the lower speed cluster may be determined, and the bandwidth may be estimated based on the representative speed.
