Abstract

A system and method for calculating, organizing and storing usage data related to multimedia broadcasts. In one illustrative embodiment, a method of the present invention comprises, receiving a plurality of data records, wherein individual records of the plurality of data records store data attributes that describe a connect time and a disconnect time of a network connection, generating an aggregate change value from the data attributes stored in the plurality of data records, and calculating a number of concurrent network connections within a predetermined time period, wherein the number of concurrent network connections is based on the aggregate change value for individual records having data attributes within the predetermined time period. In other embodiments of the present invention, the system calculates the maximum, minimum, and approximate mean values for concurrent connections.
