Abstract:
1. A system for detecting a semantic temporal event included in unprocessed video or audio data of an event from at least one data source, said system comprising: a knowledge-based modeling unit for generating multiple-layer models for identifying said semantic temporal event; a storage mechanism for storing said multiple-layer models; an observation collection unit for extracting, from said unprocessed video or audio data from the at least one data source, temporal observations according to said multiple-layer models for the semantic temporal event; and a temporal event detection unit for detecting one or more occurrences of the semantic temporal event based on said temporal observations and said multiple-layer models, wherein the semantic temporal event occurs during the event, the event has a start time and an end time, and the detected one or more occurrences of the semantic temporal event are used to facilitate selective delivery of the unprocessed video or audio data.
