Abstract

Multiple streams of media are analyzed for defects by synchronizing the streams in time and generating hashes or other representations of images of the respective streams. Where the hashes or other representations of two or more streams are sufficiently similar to one another, the streams may be determined to be similar to one another, and a determination as to whether each of the streams is defective may be made by analyzing just one of the streams. Where the hashes or other representations of two or more streams are not sufficiently similar to one another, a determination as to whether each of the streams is defective may be only made by analyzing all of the streams independently.

Dependent claims

A media distribution system in communication with at least one camera, wherein the media distribution system comprises:

at least one computer processor;
a data store;
and
a transceiver,
wherein the data store has instructions stored thereon that, when executed by the at least one computer processor, cause the media distribution system to perform a method comprising:
receiving a plurality of images captured by the at least one camera;
generating a first stream of images from the plurality of images in accordance with a first profile, wherein the first profile is associated with a first level of resolution;
generating a second stream of images from the plurality of images in accordance with a second profile, wherein the second profile is associated with a second level of resolution;
packaging the first stream of images with a plurality of sounds;
packaging the second stream of images with the plurality of sounds;
transmitting at least the first stream of images packaged with the plurality of sounds to at least a first device over one or more networks;
transmitting at least the second stream of images packaged with the plurality of sounds to at least a second device over the one or more networks;
calculating a first hash from a first image of the first stream of images;
calculating a second hash from a second image of the second stream of images;
determining that the first hash is within a threshold distance of the second hash;
in response to determining that the first hash is within the threshold distance of the second hash,
allocating at least the first stream of images and the second stream of images to a common group of streams of images;
determining, by the at least one computer processor, that the first stream of images is free of defects, wherein determining that the first stream of images is free of defects comprises at least one of:
determining that the first stream of images is not experiencing a loss of video;
determining that the first stream of images is not experiencing block corruption;
determining that the first stream of images is not experiencing a frozen video stream;
and
determining that the first stream of images does not include any artifacts;
and
in response to determining that the first stream of images is free of defects,
storing an indication that each one of the streams of images of the common group is free of defects.

23 more elements

A computer-implemented method comprising:

generating a first stream of media comprising a first plurality of images generated by at least one encoder, wherein each one of the first plurality of images is generated in accordance with a first profile at least in part from images obtained from a media source;
generating a second stream of media comprising a second plurality of images generated by the at least one encoder, wherein each one of the second plurality of images is generated in accordance with a second profile at least in part from the images obtained from the media source;
calculating a peak signal-to-noise ratio between at least one image of a first subset of the first plurality of images and at least one image of a second subset of the second plurality of images;
determining that at least the first subset corresponds in time to at least the second subset;
processing at least a first image of the first subset and at least a second image of the second subset to generate a first determination as to similarity of the first subset and the second subset;
processing the first subset to generate a second determination as to a condition of at least the first subset;
and
storing an indication of the condition of at least the first subset based at least in part on the first determination and the second determination in at least one data store,
wherein the indication identifies the condition of the first subset if the first determination is that the first subset is not similar to the second subset, and
wherein the indication identifies the condition of at least the first subset and the second subset if the first determination is that the first subset is similar to the second subset.

7 more elements

A computer-implemented method comprising:

receiving images from at least one media source;
generating a plurality of streams based at least in part on the images received from the at least one media source;
identifying, for each one of the plurality of streams, an image captured at a common time;
determining that a plurality of the images captured at the common time are similar to one another;
and
in response to determining that the plurality of the images captured at the common time are similar to one another,
identifying a subset of the plurality of streams, wherein each of the streams of the subset includes one of the plurality of images captured at the common time that are similar to one another;
selecting one of the plurality of streams of the subset;
determining that the selected one of the plurality of streams of the subset is free of defects;
and
in response to determining that the selected one of the plurality of streams of the subset is free of defects,
storing an indication that each one of the plurality of streams of the subset is free of defects.
