US 10,122,781 B2 · Selection of video segments for adaptive streaming

Abstract

Disclosed herein are system, apparatus, article of manufacture, method, and/or computer program product embodiments for selection of video segments for adaptive streaming. An embodiment operates by receiving one or more variant segments, the one or more variant segments including an old bitrate variant segment having an old bitrate and a new bitrate variant segment having a new bitrate for decoding, and playback. The embodiment farther operates by generating an old bitrate packetized elementary stream (PES) collection based on the old bitrate variant segment and a new bitrate PES collection based on the new bitrate variant segment and determining a first in-tolerance splicing location between the old bitrate PES collection and the new bitrate PES collection based on a maximum tolerance offset. The embodiment still further operates by splicing the old bitrate PES collection and the new bitrate PES collection based on the first in-tolerance splicing location.

Dependent claims

An apparatus comprising:

at least one processor;
and
a memory operatively coupled to the at least one processor, the at least one processor configured to:
receive two or more variant segments, wherein the two or more variant segments include a first variant segment having a first bitrate and a second variant segment having a second bitrate for decoding and playback,
generate a first packetized elementary stream (PES) collection based on the first variant segment and a second PES collection based on the second variant segment,
determine a first in-tolerance splicing location between the first PES collection and the second PES collection based on at least a determination of whether a presentation timestamp (PTS) associated with the first PES collection is within a tolerance offset of a PTS associated with the second PES collection, and
splice the first PES collection and the second PES collection based on the first in-tolerance splicing location.

A computer implemented method, comprising:

receiving two or more variant segments, wherein the two or more variant segments include a first variant segment having a first bitrate and a second variant segment having a second bitrate for decoding and playback;
generating a first bitrate packetized elementary stream (PES) collection based on the first variant segment and a second PES collection based on the second variant segment;
determining a first in-tolerance splicing location between the first PES collection and the second PES collection based on at least a determination of whether a presentation timestamp (PTS) associated with the first PES collection is within a tolerance offset of a PTS associated with the second PES collection;
and
splicing the first PES collection and the second PES collection based on the first in-tolerance splicing location.

2 more elements

A tangible non-transitory computer-readable device having instructions stored thereon that, when executed by at least one computing device, cause the at least one computing device to perform operations comprising:

receiving two or more variant segments, wherein the two or more variant segments include a first variant segment having a first bitrate and a second variant segment having a second bitrate for decoding and playback,
generating a first packetized elementary stream (PES) collection based on the first variant segment and a second PES collection based on the second variant segment;
determining a first in-tolerance splicing location between the first PES collection and the second PES collection based on at least a determination of whether a presentation timestamp (PTS) associated with the first PES collection is within a tolerance offset of a PTS associated with the second PES collection;
and
splicing the first PES collection and the second PES collection based on the first in-tolerance splicing location.
