Near video-on-demand system and broadcasting method therefor

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 including a number of first in, first out memory 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;
• and
• matrix 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 incorporating therein in a plurality of channels,
• wherein if the number of said first-in, first-out memory means is N and said additional information program is incorporated at M locations, then the number of the channels is N+M.
