Television broadcast system for selective transmission of viewer-chosen programs at viewer-requested times
DC CAFCFirst Claim
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, andpreventing 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.

2. 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 in 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; said receiver associated with said requesting viewer being distinguishable from other receivers in said system by an identifier, providing computer means operable for receiving from said requesting viewer encoded signals representative of said chosen program, said requested time, and the identifier of said receiver associated with said requesting viewer, said selecting step including the step of selecting said chosen program from said collection in response to said encoded signals from said requesting viewer. - View Dependent Claims (3)

4. In a television transmission system using land lines for transmitting programs for reception by a plurality of television receivers coupled with the land lines for viewing of the programs on the receivers by viewers respectively associated therewith, and including communicating means for communicating information as encoded signals over the land lines from said viewers, the improvement comprising:
-
a collection of stored programs stored on a medium allowing selective reproduction and real-time transmission over the land lines for reception and viewing thereof by selected receivers; computer means operably coupled with the communicating means for receiving encoded signals from a requesting viewer, said encoded signals being representative of a requesting viewer'"'"'s choice of a program chosen from said collection and said requesting viewer'"'"'s requested time for viewing of said chosen program on a receiver associated with said requesting viewer and for providing output information representative thereof; selecting means operably associated with said collection and said computer means and responsive to said output information for selecting said chosen program from said collection; and transmitting means operably associated with and responsive to said selecting means for transmitting said chosen program over the land lines at said requested time for reception by and viewing on said requesting viewer'"'"'s receiver. - View Dependent Claims (5, 6)

7. In a television transmission system using land lines for transmitting programs for reception by a plurality of television receivers coupled with land lines for viewing of the programs on the receivers by viewers respectively associated therewith, the system further including communicating means for receiving information over land lines from the viewers, the land lines including a section thereof having a subset of the receivers coupled therewith wherein said subset includes a plurality of receivers less than the total number of receivers included in the system, the remaining portion of the land lines having a plurality of receivers other than the subset coupled therewith, the section and the remaining portion being coupled with one another at a juncture, the improvement comprising:
-
a collection of stored programs stored on a medium allowing selective reproduction and real-time transmission thereof over the land lines for reception and viewing thereof by selected receivers; receiving means operably associated with the communicating means for receiving information from a requesting viewer, said information including a requesting viewer'"'"'s choice of a program chosen from said collection and a requested time for viewing of said program on a receiver associated with said requesting viewer, said associated receiver being included in the subset of receivers; selecting means operably associated with said collection and operably associated with and responsive to said receiving means for selecting said chosen program from said collection; transmitting means operably associated said selecting means and coupled with the section of the land lines for transmission of said chosen program at said requested time for reception by and viewing on said receiver associated with said requesting viewer; and blocking means located in the vicinity of the juncture for preventing transmission of the chosen program therebeyond from the section into the remaining portion of the land lines. - View Dependent Claims (8, 9)

10. A method of operating a television transmission system for transmitting programs thereover for reception by a plurality of receivers coupled with the system for viewing of the programs by viewers associated with the receivers, said method comprising the steps of:
-
providing a central unit having a collection of stored programs stored on a medium allowing selective reproduction and real-time transmission of said programs over the system; transmitting to said central unit a viewer'"'"'s request of a viewer-chosen program chosen from said collection and of a viewer-requested time for viewing said chosen program; responding in said central unit to said viewer'"'"'s request by selecting said viewer-chosen program from said collection and by transmitting in real time over the system said viewer-chosen program at said viewer-requested time for reception by the receiver associated with said requesting viewer; and preventing intelligible viewing of said viewer-chosen program at said viewer-requested time on receivers other than said receiver associated with said requested viewer. - View Dependent Claims (11, 12, 13, 14, 15, 16)
