| Abstract: |
A television broadcast system using land lines is provided for real-time transmission of a viewer-chosen program at a viewer requested time to the requesting viewer's television receiver. The preferred method includes the steps of providing a collection of stored programs, communicating the requesting viewer's choice of a program chosen from the collection and a requested time for viewing the chosen program, selecting the chosen program from a collection, transmitting the chosen program at the requested time for viewing on the requesting viewer's receiver, and preventing intelligible viewing of the chosen program on other receivers.

Having thus described the preferred embodiments of the present invention, the following is claimed as new and desired to be secured by Letters Patent:
1. A method of operating a television transmission system using land lines for transmitting television programs for reception by a plurality of receivers coupled with land lines for viewing the programs on the receivers by viewers respectively associated therewith, the system including means for selectively preventing intelligible viewing of certain programs by certain receivers, said method comprising the steps of:
- providing a collection of stored programs stored on a medium allowing selective reproduction and real-time transmission of said stored programs over the land lines;
- selecting a prospective chosen program from said collection for transmission at a requested time in response to a request therefor from a requesting viewer;
- transmitting said chosen program in real-time over the land lines at said requested time for reception by and viewing on a receiver associated with said requested viewer;
- preventing intelligible viewing of said chosen program at said requested time on receivers other than said receiver associated with said requesting viewer;
- identifying a section of the land lines having a subset of receivers operably coupled thereto wherein said subset includes a plurality of receivers less than the total number of receivers included in the system, and remaining portions of the land lines having a plurality of receivers other than said subset coupled thereto,
- transmitting said chosen program over said section of the land lines,
- identifying a juncture between said section and said remaining portion, and
- preventing transmission of said chosen program beyond the juncture from said section to said remaining portion by use of a blocking device located at said juncture.
