1. A method comprising:

  • receiving, by one or more processors, queries from devices, wherein the queries include respective samples of content from a stream of content rendered by a source;

    receiving, by the one or more processors, samples of content from a stream of content rendered by an alternative feed of the source;

    for each sample of content from the alternative feed of the source, identifying respective matching queries that match to the same content as the sample of content from the alternative feed of the source;

    for each respective matching query, determining a respective relative time difference between a time that the content appears in the sample of content from the alternative feed and a time that the content appears in the respective matching query;

    accumulating a distribution of the time differences over time; and

    based on the distribution of the time differences, determining, by the one or more processors, a latency between the source and the alternative feed of the source.
