A near video on demand time shifting feature for a subscriber terminal emulates the video cassette recorder functions of pause, fast forward, and rewind for a NVOD service subscription. The subscriber terminal stores global transactions concerning NVOD events in an event portion of memory. The subscriber terminal provides an on screen display feature for assisting in ordering the NVOD service and a user interface which provides the functions of pause, fast forward and rewind. When viewing a NVOD event, if the subscriber selects the pause function, the subscriber terminal causes a pause on screen display to be viewed for one time increment. After the elapse of the time increment, the subscriber terminal will tune the channel of the next showing which is one time increment earlier than that presently viewed. If the subscriber selects the rewind function, the subscriber terminal will tune the channel of the next showing which is one time increment earlier than that presently viewed. If the subscriber selects the fast forward function, the subscriber terminal will tune the channel of the previous showing which is one time increment later than that presently received.

A method of time shifting the viewing of a programmed event in a near video on demand (NVOD) system including a plurality of near video on demand channels, each channels having the event shown spontaneously and sequentially on each of the channels, but time shifted a different number of predetermined time increments, wherein each programmed event has a first show interval, a last show interval and a plurality of show intervals therebetween and wherein the duration between show intervals is equal to the duration of the predetermined time increments, the method comprising the steps of: viewing the programmed event on a preset NVOD channel; periodically providing a present showing number which corresponds to the relative time that has passed since a start of the programmed event; selecting a forward time shift for viewing the program event; determining if the present showing number is during a last show interval when the forward time shift is selected; tuning in response to said forward time shift being selected from the present NVOD channel to a NVOD channel carrying the program event which started the event one time increment later than the present NVOD channel when the present showing number is determined to occur before the last show interval; and preventing tuning in response to said forward time shift being selected when the present showing number is determined to occur during the last show interval.
