Abstract

Disclosed are systems and methods to deliver media files at a highest perceived presented quality. Rather than measure quality as a difference between an encoded version of the media file and the original version of the media file, in accordance with the disclosed implementations, quality is based on a presented quality of each fragment of a media file when presented by a device to a user. The disclosed implementations determine a presented quality score for each fragment of a media file, the presented quality score indicative of a predicted quality of the fragment as perceived by a user when the fragment is presented. The presented quality score may be determined based on one or more of a bitrate used to encode the media segment, a device type of a device used to present the media segment, the content of the segment itself, etc.

Dependent claims

A computer-implemented method, comprising:

determining, for each fragment of a first plurality of fragments of a first media file that were downloaded by a first device, a first plurality of estimated parameters determined for the download of each of the first plurality of fragments to the first device, wherein at least some of the first plurality of estimated parameters are determined based at least in part on first presented quality scores determined for each fragment of the first plurality of fragments, wherein the first presented quality scores are indicative of a first predicted quality of the fragment of the first plurality of fragments when presented by the first device;
determining, for each of the first plurality of fragments of the first media file, a first plurality of actual parameters for delivery or presentation of each of the first plurality of fragments of the first media file to the first device;
computing, based at least in part on the first plurality of estimated parameters and the first plurality of actual parameters, a first plurality of parameter accuracy scores corresponding to the first media file and the first device;
determining, for each fragment of a second plurality of fragments of a second media file that were downloaded by a second device, a second plurality of estimated parameters determined for the download of each of the second plurality of fragments to the second device, wherein at least some of the second plurality of estimated parameters are determined based at least in part on second presented quality scores determined for each fragment of the second plurality of fragments, wherein the second presented quality scores are indicative of a second predicted quality of the fragment of the second plurality of fragments when presented by the second device, wherein the second media file is different than the first media file;
determining, for each of the second plurality of fragments of the second media file, a second plurality of actual parameters for delivery or presentation of each of the second plurality of fragments of the second media file to the second device;
computing, based at least in part on the second plurality of estimated parameters and the second plurality of actual parameters, a second plurality of parameter accuracy scores corresponding to the second media file and the second device;
aggregating the first plurality of parameter accuracy scores determined for the first media file and the first device and the second plurality of parameter accuracy scores determined for the second media file and the second device to produce a plurality of aggregated media files and device type parameter accuracy scores;
and
causing one or more actions based at least in part on one or more of the first plurality of parameter accuracy scores, the second plurality of parameter accuracy scores, or the plurality of aggregated media files and first device type parameter accuracy scores.

A computing system comprising:

one or more processors;
and
a memory storing program instructions that, when executed by the one or more processors, further cause the one or more processors to at least:
determine a first plurality of estimated parameters for a first media file sent to a first device, wherein at least some of the first plurality of estimated parameters are determined based at least in part on one or more first presented quality scores determined for the first media file, wherein each of the first one or more presented quality scores are indicative of a first predicted quality of at least a portion of the first media file when presented by the first device;
determine, for the first media file, a first plurality of actual parameters for delivery of at least a portion of the first media file to the first device;
compute, based at least in part on the first plurality of estimated parameters and the first plurality of actual parameters, a first parameter accuracy score corresponding to the first media file and the first device;
determine a second plurality of estimated parameters for a second media file sent to a second device, wherein at least some of the second plurality of estimated parameters are determined based at least in part on one or more second presented quality scores determined for the second media file, wherein each of the second one or more presented quality scores are indicative of a second predicted quality of at least a portion of the second media file when presented by the second device, wherein the second media file is different than the first media file;
determine, for the second media file, a second plurality of actual parameters for delivery of at least a portion of the second media file to the second device;
compute, based at least in part on the second plurality of estimated parameters and the second plurality of actual parameters, a second parameter accuracy score corresponding to the second media file and the second device;
aggregate the first parameter accuracy score and the second parameter accuracy score to produce an aggregated media files and first device type parameters accuracy score;
and
cause one or more actions based at least in part on the first parameter accuracy score, the second parameter accuracy score, or the aggregated media files and first device type parameter accuracy score.

9 more elements

A method, comprising:

determining one or more first estimated parameters for a first media file, wherein at least one of the one or more first estimated parameters are determined based at least in part on one or more first presented quality scores determined for the first media file, wherein each of the one or more first presented quality scores are indicative of a first predicted quality of at least a portion of the first media file when presented by a first device;
determining, for the first media file, one or more first actual parameters measured during a delivery or a playback of the first media file by the first device;
computing, based at least in part on the one or more first estimated parameters and the one or more first actual parameters, one or more first parameter accuracy scores corresponding to the first media file and the first device;
determining one or more second estimated parameters for a second media file, wherein at least one of the one or more second estimated parameters are determined based at least in part on one or more second presented quality scores determined for the second media file, wherein each of the one or more second presented quality scores are indicative of a second predicted quality of at least a portion of the second media file when presented by a second device, wherein the second media file is different than the first media file;
determining, for the second media file, one or more second actual parameters measured during a delivery or a playback of the second media file by the second device;
and
computing, based at least in part on the one or more second estimated parameters and the one or more second actual parameters, one or more second parameter accuracy scores corresponding to the first media file and the second device;
aggregating the one or more first parameter accuracy scores and the one or more second parameter accuracy scores to produce one or more aggregated media files and device type parameter accuracy scores;
and
causing one or more actions based at least in part on the one or more first parameter accuracy scores, the one or more second parameter accuracy scores, or the one or more aggregated media files and first device type parameter accuracy scores.
