Parent Case Info

This is a continuation-in-part of our copending application Ser. No. 07/144,328 filed Jan. 15, 1988 "Dispenser Storage System". This invention relates in general to video cassette player to television player systems, and in particular, to a video cassette tilt bin library and video cassette cabinet in a tilt rack video cassette storage library and VCP to multiple subscriber system. There are various systems and ways of supplying pay-per-view movies, or video cassettes for independent playing of movies and programs via video cassette players, for television in the home, apartment complex, hotel, motel, hospital and other locations. The advent of fiber optics and the ability to carry large amounts of information over a single strand enables various locations to receive cable television programming, switched video and telephone service over optic fiber. Such locations are capable of receiving a plurality of downstream switched video channels and upstream video channel switching. With this system and other cable systems, from the entertainment standpoint, it means that instead of going to the video rental store you could request a movie and it would be played down the line to you for a fee. A downstream switching system would in some systems also allow for video catalog shopping. Spectradyne is presently the nations largest provider of pay-per-view movies providing service at this time to more than 600,000 North American hotel guest rooms. Comsat Video Enterprises is also active in this market. Generally, however, these and other companies provide pay-per-view showings (various program choices at a time) according to their schedules rather than at the subscriber's convenience. Thus there is a need for a video cassette library system along with video cassette players computer controlled by transmitted signal inputs from a television set subscriber location. This provides for transport of a selected program (movie) cassette to a video cassette player for program transmission through a selected channel to a specific subscriber location. It is therefore a principal object of this invention to provide a video cassette player (VCP) to television multiple subscriber system with a video cassette storage multi-bin library cabinet also containing a plurality of VCP's for dedicated use by subscribers at their time convenience. Another object with such a VCP to television multiple subscriber system is to provide a tilt rack cabinet with multiple cassette storage bins served by a tape cassette selection, delivery and return system. A further object with such a VCP to television multiple subscriber system is to eliminate rent out and dispensing of video cassettes to the general public. Still another object is to provide a protective environment for video cassettes with cassette movement from tilt rack bin storage to a VCP and return to bin storage after play by a computer controlled XYZ transport structure. Features of the invention useful in accomplishing the above objectives include, in a tilt rack video tape cassette library and VCP to multiple subscriber television play system, a tilt rack video cassette library containment cabinet containing multiple VCP units with an XYZ motion tape cassette selection and delivery system to computer directed insertion in a subscriber VCP and return after play to a tilt rack library storage bin. The system includes activation means, movie selection means and a TV set at each subscriber location, an address mechanism in the system and a telephone connection through a duplex modem to a computer having a monitor and keyboard with computer controlling XYZ carrier movement pick up of cartridges from and return to video cassette storage bins, insertion and extraction of selected video cassettes to and from subscriber video cassette players (VCP). Each VCP has an audio and video output connection to respective modulators each output connected to a combiner mixer There is also a character-modulator loop connection, and a computer to combiner mixer address transmitter loop along with a character generator modulator loop, with the mixer output connected to address control circuits. Specific embodiments representing what are presently regraded as the best modes of carrying out the invention are illustrated in the accompanying drawings. In the drawings: FIG. 1A represents a block schematic of a parallel (home run) wired facilty with telephone order entry box in a video cassette tilt bin library and video cassette tilt rack (cabinet) bin library with VCP to multiple television play subscriber system; FIG. 1B, a block schematic like FIG. 1 of a parallel (home run) wired facility with telephone/voice response order entry system; FIG. 1C, a block schematic of a system having a series (loop) wired facility with addressable switch and telephone order entry boxes; FIG. 1D, a block schematic of a system having a series (loop) wired facility with set-top addressable converters and telephone order entry boxes; FIG. 1E, a block schematic of a system having a series (loop) wired facility with set-top addressable converters and telephone voice response entry; FIG. 1F, a block schematic of a system having a series (loop) wired facility with addressable switches and telephone voice response order entry; FIG. 2, a perspective view of a self contained tilt rack video cassette library cabinet with multiple VCP unit bins and multiple video cassette tilt storage bins in vertical columns and a XYZ carrier that picks up cartridges, delivering them to available VCP units and after use return them to respective video cassette tilt storage bins; FIG. 3, a top plan view partially cut away and sectioned showing additional detail of the self contained tilt rack video cassette library cabinet of FIG. 2; FIG. 4, a partial cut away perspective view showing VCP mounting bins and some cassette storage bins and some XYZ cassette carrier mechanism detail; FIG. 5A, a partial cut away and sectioned view taken from line 5A--5A of FIG. 3 showing XYZ video cassette carrier mechanism detail and bin detail; FIGS. 5B and 5C, partial views showing additional XYZ cassette carrier mechanism detail including different positions of a cassette position tap down linkage structure; FIG. 6, a partial perspective showing of a XYZ movement video cassette pick up and movement plate as related to the front bottom of a cassette storage bin; FIG. 7, a partial view partially cut away and sectioned of a prior art video cassette player showing detail of a hold structure; FIG. 8, a partial broken away and sectioned view of a VCP mounted in place in a VCP tilt rack bin with cassette friction hold release detail; FIG. 9, a friction hold release plate addition to video cassette players.
