1. For use in cooperation with a computer having memory, a method of placing video circuits in an interactive video delivery system, comprising:

  • determining peak loading hours;

    determining a number of system subscribers in the video delivery system;

    determining a blocking probability of the system in accordance with the formula;

    ##EQU11## where;

    M equals the number of system subscribers,n equals a number of movies simultaneously playing at peak loading hours,p equals a probability that a subscriber will request a movie during a selected time window prior to peak loading hours,C equals a number of circuits available in the video delivery system;

    storing in the memory of the computer blocking probability data corresponding to the determined blocking probability;

    determining from the blocking probability data a number of video circuits required to meet the determined blocking probability; and

    placing the determined number of video circuits in the interactive video delivery system.
