See Dunn, column 3, lines 28-35. Referring to Figure 3, Dunn
teaches the order button 76 enables the user to order a video

contains program titles, runtime length of the programs, program
IDs, program monikers, trailer IDs, trailer monikers, and rental
periods. See Dunn, column 9, lines 20-26. Dunn further teaches
that the headend will transmit the rented video content program

associated with that movie has not lapsed. The rental period is
longer in duration than the runtime length of the associated
video program. For instance, the rental for program "title 2"
has a 48 hour rental period, as indicated by the associated
rental period in the program table 110 shown in Figures 6 and 10.
The viewer may wish to watch the program many different times
within the 48 hour period. This aspect is akin to renting a
