For providing video-on-demand (VOD) a set comprising a plurality of N video programs at staggered time intervals is repeatedly transmitting from a VOD server to a network for access by a view box of an user; responsive to a request for access to a selected program by the user, there is selection of that in-progress transmission of the selected program for which a lead-in portion is shortest and storage of the program in a buffer associated with the view box as it is transmitted. A previously stored beginning portion of the selected program having a time length sufficient to compensate for that time interval is selected, in a memory associated with the view box, and outputting to the view box for display. The in-progress transmission stored in the buffer is continuously spliced to a conclusion of the beginning portion. All different video programs in a same set are transmitted with mutual time shifts equal to a fraction of the staggered interval.
