Amusement and information system for use on a passenger carrier
BACKGROUND OF THE INVENTION 
     The invention concerns an amusement and information system for use by passengers on commercial carriers (air lines, railroads, busses) from which different entertainment may be selected. 
     Selective viewing, per se, is known as in U.S. Pat. No. 4,381,522 to Lambert, wherein a telephone is dialed to select from a listing of programs available to a remote receiving location from which the dialing is completed. U.S. Pat. No. 4,450,477 to Lovett teaches a television information system in which subscribers transmit to a computer a video request for desired information which is processed such that the information is generated to the subscriber. Templin et al. disclose in U.S. Pat. No. 4,375,651 a selective video reception system. Here, groups of VHF, UHF or CATV channels are programmed by a key switch, and individual channels within the groups may be selected by means of selector keys. A communication network having master and remote stations, each having a television receiver to which a common video tape recorder may be selectively connected, is shown in Roscoe&#39;s U.S. Pat. No. 4,249,206. U.S. Pat. No. 4,028,733 to Ulicki discusses a system for providing a video display of a pictorial information message on a video display device. 
     Passenger rail cars and busses typically provide no entertainment for the passengers who must amuse themselves by reading, for instance. On some airlines a movie is provided, however, the passengers have a choice only between watching or not watching a pre-selected movie. An airliner may also have a selection of audio tapes are available to the passengers for listening. Generally, a substantial amount of time is spent peering from the airliner window at the scenery below. 
     OBJECTS AND SUMMARY OF THE INVENTION 
     It is a first objection of this invention to provide an amusement and information system for simultaneous use by many people. 
     It is another object of this invention to provide an amusement and information system which allows the individual user to choose between different amusement and information devices. 
     A further object of the invention is to provide an amusement and information system for use on a passenger carrier, which when installed consumes a negligible amount of space. 
     Each seat of a passenger carrier, such as an aircraft, is provided with an entertainment terminal which informs and amuses the seat occupant. The entertainment terminal having a display and keyboard is attached and positioned in the back of the first seat in a manner similar to currently used drop-trays, for operation by a person sitting in a second seat behind the first seat. The keyboard is used to select from a wide variety of entertainment, such as games, movies, current flight path information, crew information or to signal that the assistance of a crew member is desired. A proper keying sequence connects an occupant&#39;s video display to one of many video movie players, allowing the occupant to view a movie of his choice. Another sequence keyed via the keyboard yields a choice of pre-programmed video games. The occupant may also key for personal information concerning the flight crew; name, rank, flight experience. When flying most passengers cannot identify a city which passes below, but often wonder as to its identity. Accordingly, the occupant may key for flight path information. The name of the city, its relative size, and a map may be generated which locates and identifies points of interest. The flight crew and path information, and video movies and games are accessed through a selector which interprets the keyed sequence. A single key on the keyboard is used for summoning a flight attendant to obtain food, drink, etc. Actuation of this key illuminates an attendant&#39;s video panel in a manner that indicates which occupant actuated his or her key. The keyboard and video display are mounted in a seat back, the keyboard being pivotable away from the seat to a horizontal position. A clear lens-like tray parallels the seat back and covers the video display. Thus, the display is entirely visible through the vertically positioned clear tray. In a horizontal position, the clear tray functions as a table to hold food, drinks, etc. while the video display is viewed directly.

     DETAILED DESCRIPTION OF THE INVENTION 
     FIG. 1 shows a block diagram of the amusement and information system, generally indicated at 10. Included in the system 10 is an entertainment terminal 12 (typical of a plurality) having a keyboard 14 which is used to select the amusement or information which appears on video display 16. Keys (now shown) of the keyboard 14 are actuated in a pre-determined sequence, in a manner which determines the operation of selector 18. In effect, the keyboard 14 &#34;gates&#34; the selector 18, allowing amusement or information to be displayed on the video display 16. According to the keyed sequence, any one of a plurality of entertainment devices may be accessed. The selector 18 associated with each entertainment terminal 12 is connected to a plurality of video recorder/players 20, 22, etc. According to the preferred embodiment of the invention, each video recorder/player 20, 22, etc. is used to show a different movie. Thus, the seat occupant, depending on the appropriate keying sequence, may select from a number of movies, rather than, as is the present practice, view one movie chosen by the airline. Another different keying sequence is utilized to access a flight path information computer 24. Generated on the video display 16 will be, for instance, the name of a city below the airliner, its population, relative size and a map of the city. The map may contain points of interest that are visible from the air. The information in the flight path information computer is updated as the flight progresses so that the data appearing on the video display 16 corresponds with the city or terrain that is below the aircraft. Appropriate codes are typed into the keyboard 14 and the selector 18 now connects the video display 16 to the flight crew data memory 26. Information concerning the flight crew is stored in memory at 26. A seat occupant may determine the names, rank and flight experience of the crew members. Any amount of personal information may be stored, however, the privacy of the crew is to be taken into consideration. A digital storage device 28 may be connected to the video display 16 by the selector 18 in accordance with a keying sequence, providing a choice of video games. In this instance the keyboard also functions to control the movement of any characters which appear in the game. A special, single key appearing on each keyboard 14 may be actuated which is directly connected to a flight attendant&#39;s video panel. Actuation of this key indicates to a flight attendant that the actuator/occupant desires the assistance of the flight attendant. An appropriate signal, such as a seat number, appears on the panel 30 so that the flight attendant is aware of the assistance-needing passenger. A series of other entertainment terminals 32, 34 are connected in a similar fashion via their respective selectors 36, 38 to the amusement and information devices. Thus, the devices (20, 22, 24, 26, and 28) may be accessed by any number of passengers having an entertainment terminal. 
     In FIG. 2 the back 40 of an airline seat is shown, to which an entertainment system terminal 12 is attached. The video display 16 is integrally connected to the seat back 40 and is parallel thereto. The keyboard 14, in this embodiment, is mounted to the seat back 40 below the video display 16. The keyboard 14 is shown in a vertical position (for aircraft take-off and landing) secured to the seat back 40 by hinge members 42. A clear, lens-like tray 44 is shown in an upright position, through which the video display 16 can be seen. The clear tray 44 is attached to the seat back 40 in a manner similar to that of typical drop-trays. As an example, the clear tray is hinged at 46. 
     FIG. 3 shows a side view of the seat back 40, but with the clear tray in a horizontal position. In this position the clear tray 44 functions as a drop-tray, being a support for food, drinks, etc. The video display 16 may be viewed directly in a normal manner. 
     FIG. 4 shows the entertainment terminal 12, oriented for operation. Here, the keyboard 14 is pivoted to a horizontal position about its hinged member 42. The clear tray 44 parallels the video display 16 which is viewed therethrough. Accordingly, the seat occupant keys in a desired sequence on keyboard 14, a video movie or game, or flight crew or path information appearing on the video display 16. The lens-like quality of the clear tray 44 provides an unobstructed view of the video display 16, and may be designed to magnify the images thereon. In an alternate embodiment, the keyboard 14 may be attached to the seat back 40 above the video display 16 so that an occupant may utilize the tray in its horizontal position while operating the entertainment terminal. 
     Other modifications are apparent to one skilled in the art, which do not depart from the spirit of the present invention. The scope of the invention being defined by the appended claims.
