US 2020/0005048 A1 · TRANSFORMATION OF VIDEO STREAMS

Abstract

Example aspects for transformation of video streams include searching for a first signature of a segment of a video stream in an index comprising a first level signature of each of a plurality of stored segments. In response to identifying a first set of similar segments from the stored segments, a second signature of the segment may be determined. In response to identifying a second set of similar segments from the first set of similar segments based on the second signature, a matching segment may be ascertained from the second set of similar segments. The matching segment may be provided for being stored in place of the segment in a storage medium.

Dependent claims

A method for transformation of a video stream at an edge device, the method comprising, for each segment of the video stream:

searching for a first signature of a segment of the video stream in an index comprising a first level signature of each of a plurality of stored segments;
in response to identifying a first set of similar segments from the stored segments, determining a second signature of the segment;
in response to identifying a second set of similar segments from the first set of similar segments based on the second signature, ascertaining a matching segment from the second set of similar segments;
and
providing the matching segment for being stored in place of the segment in a storage medium.

A computing device comprising:

a processor;
and
a memory coupled to the processor, the memory storing instructions executable by the processor to:
intercept a video stream and obtain segments from the video stream;
and
for each of the segments,
search for a matching segment from among stored segments, the search being based on a comparison of a first signature of a segment with a first level signature of each of the stored segments and a comparison of a second signature of the segment with a second level signature of each of a subset of the stored segments, wherein the first signature is based on summarized descriptors of the segment and the second signature is based on detailed descriptors of the segment;
store the matching segment in place of the segment in a storage medium when the matching segment is found;
and
provide the segment for being stored in the storage medium when no matching segment is found.

A non-transitory computer-readable medium comprising computer-readable instructions for transformation of a video stream, the computer-readable instructions when executed by a processor cause the processor to:

obtain segments from the video stream, each segment being one of a key frame and a snippet;
and
for each segment:
identify a first set of similar segments from the stored segments based on a comparison of a first signature of the segment with a first level signature of each stored segment;
when the first set of similar segments includes at least one stored segment, identify a second set of similar segments from the first set of similar segments, wherein a similar segment of the first set of similar segments is selected to be in the second set of similar segments when a difference value obtained on comparison between a second signature of the segment and a second level signature of the similar segment is less than a threshold;
when the second set of similar segments includes at least one similar segment, ascertain a matching segment from the second set of similar segments;
and
provide the matching segment for being stored in place of the segment in a storage medium.
