US 10,484,730 B1 · Chunked transfer mode bandwidth estimation

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.

Dependent claims

A computing system for estimation of a bandwidth for chunked transfer mode comprising:

one or more processors;
and
one or more memories having stored therein instructions that, upon execution by the one or more processors, cause the computing system perform operations comprising:
determining a first speed associated with delivery of a first chunk;
selecting, from a plurality of chunk groups, a first chunk group within which to include the first chunk, wherein the first chunk group is selected based at least in part on the first speed;
determining a representative speed that represents speeds of a plurality of chunks included in the first chunk group;
and
estimating the bandwidth based, at least in part, on the representative speed.
