Abstract: In some implementations, a computer-implemented method includes analyzing first data from a first data source to determine a first schema of the first data source, and analyzing second data from a second data source to determine a second schema of the second data source. The method can further include generating a first two-dimensional aggregation of a first time data series having a time dimension and a dimension corresponding to aggregated values of a first metric, and generating a second two-dimensional aggregation of a second time data series having a time dimension and a dimension corresponding to aggregated values of a second metric. The method can also include computing a correlation value between the first two-dimensional aggregation and the second two-dimensional aggregation, and providing an indication of duplicated data between the first data source and the second data source if the correlation value meets a threshold.

Abstract: A method for recording audio and/or video of an event on a plurality of recordable media comprises the steps of capturing audio and/or video at the event from at least one pickup to a recording station, transferring the captured audio and/or video from the recording station to a file server for storage, copying the captured audio and/or video from the file server to at least one computer, and recording the audio and/or video from the at least one computer to the plurality of recordable media. The captured audio and/or video may be separated into content files representing songs or topics. The captured audio and/or video may be copied from one computer to another computer, which may also record to the media. A robotic duplication system may be attached to the computer. The file server is instructed to begin the copying process once all audio and/or video has been captured.
