Abstract:
A near video-on-demand system comprising:control means;high-speed digital reproducing means responsive to a control signal from said control means, for reproducing at a high rate a plurality of video-on-demand system recording data divided from digital data of a main program and recorded at discrete areas;an additional information program data server for reproducing data of an additional information program in response to a control signal from said control means;buffer means responsive to a control signal from said control means, for selectively writing the video-on-demand system recording data from said high-speed digital reproducing means and reading the video-on-demand system recording data; andmatrix switcher means responsive to a control signal from said control means, for selectively outputting main program data from said buffer means and additional information data from said additional information program data server, and sequentially transmitting the main program data with the additional information data incorporated at M locations therein to a number of channels,wherein the number of channels to which the matrix switcher means transmits the main program data and the additional information data in predetermined time intervals is (N+M), in which N represents the number of channels to which the main program data without the additional information data would be transmitted to in the predetermined time intervals.
