Abstract: A computing system receives event data that includes play-by-play information for an event. The computing system accesses a database that includes a knowledge graph related to the event. The knowledge graph includes a plurality of nodes and a plurality of edges. Each node of the plurality of nodes represents a player or a team involved in the event. The plurality of edges connects nodes of the plurality of nodes. The computing system updates the knowledge graph based on the play-by-play information. The computing system generates, via a first machine learning model, one or more insights based on the updated knowledge graph. The computing system scores, via a second machine learning model, a score for each of the one or more insights. The computing system presents a highest ranking insight of the one or more insights to one or more end users.

Abstract: An original digital audio signal represents unimpaired audio information. The digital audio signal is compressed and encrypted without substantial impairment to produce a first audio signal. A second, unencrypted, audio signal is produced. The first and second audio signals are combined. Preferably the first audio signal is losslessy compressed. The second audio signal may be an impaired version of the original digital audio signal.
