`an pecap
`ohaptec)lp(276g.imentiof’ relates to video display systems,
`
`
`
`and more specifically to video display systems mounted in
`
`5
`
`and operating in mass transit subway cars.
`
`
`
`It is commonplace to provide visual advertising
`
`displays such as posters in mass transit subway cars, where
`
`the displays are available for reading by subway passengers
`
`10
`
`during travel.
`
`It is also known to equip subway cars with
`
`closed circuit
`
`television cameras,
`
`for surveillance of
`
`passenger behaviour and other safety checks.
`
`Images of
`
`such surveillance are either displayed at
`
`a
`
`central
`
`security facility, or recorded for subsequent viewing in
`
`15
`
`the event of safety problems.
`
`It is also commonplace to equip subway cars with
`
`a myriad of uses,
`for
`systems
`address
`audio public
`including transit service announcements, community service
`events, advertising, safety and emergency procedures, as
`
`20
`
`well as inter-staffi communications.
`
`Proposals have been made previously to equip
`
`other
`
`transportation items,
`
`especially aircraft, with
`
`25
`
`television
`
`or
`
`video
`
`systems,
`
`primarily
`
`for
`
`the
`
`entertainment of passengers on long journeys.
`
`Examples of
`
`such systems in the patent literature can be found in U.S.
`
`Patent 4,647,980 Steventon et al., U.S. Patent 4,630,821

`
`al.
`
`Entertainment of passengers on subway cars has
`
`until now generally been ignored, since the average journey
`
`35
`
`taken by a passenger on a mass
`
`transit
`
`subway system is
`
`usually
`
`short,
`
`lasting
`
`perhaps
`
`fifteen minutes.

`
`Nevertheless,
`
`subway transit riders offer an attractive
`
`audience for visual advertising messages, as evidenced by
`the proliferation of advertising signs which commonly adorn
`a subway car.
`In addition, mass transit systems such as
`
`subways are in need of extra sources of revenue,
`
`to keep
`
`as
`level
`an affordable
`structures at
`fare
`passenger
`operating costs rise, and to avoid decreased ridership as
`
`a result.
`
`
`
`10
`
`15
`
`It
`
`is an object of
`
`the present
`
`invention to
`
`provide
`
`a
`
`public
`
`service message
`
`display
`
`system,
`
`entertainment
`
`system and advertising system for mass
`
`transit subway cars.
`
`It is a further object to provide a novel source
`
`of extra revenue for a mass transit subway system.
`
`The present
`
`invention provides
`
`a
`
`television
`
`public
`
`service message
`
`display,
`
`entertainment
`
`and
`
`20
`
`advertising system for subway cars,
`
`in which television
`
`25
`
`30
`
`monitors are provided at spaced intervals in subway cars,
`to display short duration televisual entertainment
`and
`advertising features to subway riders.
`The
`system is
`
`designed so that advertising spots om it can be sold by the
`
`for
`transit system to potential advertisers and sponsors,
`extra revenues for the transit system.
`It takes advantage
`of
`the fact
`that
`subway riders are,
`for
`the most part,
`
`occupying a subway car under relatively crowded conditions
`
`but for only a relatively brief duration. They are looking
`
`their attention during
`for something on which to focus
`their brief ride, whilst at the same time often finding it
`
`the like
`to open newspapers, magazines or
`inconvenient
`under crowded circumstances and becoming bored by static
`
`advertising or other displays around them. The present
`
`Hr0
`
`
`P. 10

`
`. J
`
`
`
`
`invention provides properly positioned television monitors
`
`Gisplaying moving
`images
`of
`news
`items,
`advertising
`material and the like, viewable by substantially all riders
`in the car, and filling their need for visual entertainment
`
`during the brief duration of their subway ride.
`
`Thus, according to the present
`
`invention,
`
`from
`
`one aspect,
`
`there is provided a video system for displaying
`
`to passengers in a mass transit Subway
`televised material
`car,
`and comprising at
`least one video display monitor
`
`adapted for mounting inside a subway car so as to display
`
`televised materials to passengers riding therein,
`
`and a
`
`video signal source unit operatively connected to said at
`
`least one monitor.
`

`
`15
`
`invention,
`
`the present
`second aspect of
`According to a
`there
`is provided a
`subway
`car
`for mass
`
`transportation and
`
`comprising a video display system
`
`including at least one video display monitor having a video
`
`20
`
`screen,
`
`the monitor being mounted in the subway car ina
`
`manner
`
`such that
`
`the video screen thereof
`
`is
`
`readily
`
`visible to passengers in the subway car, and a video signal
`source unit operatively connected to said at
`least one
`monitor.
`
`25
`
`The
`
`term “video signal
`
`source unit"
`
`as used
`
`herein embraces player units for playing pre-recorded video
`material,
`such as computer-based digital video recorders
`(including CD-ROM players), video tape players and video
`
`30
`
`disk players, and television receivers for receiving live
`
`or pre-recorded broadcast television signals from a remote
`transmitter
`and supplying these to the video display
`monitors mounted in the subway cars. One system according
`
`to the invention utilizes receivers including computer-
`
`Aa
`
`
`P. 11
`
`

`

`S
`
`S
`
`based digital video recorders
`
`for
`
`receiving broadcast
`
`television signals from a remote transmitter as the video
`
`signal source unit.
`
`Such video signal source unit can be
`
`located either within the mass transits' premises or on a
`
`5
`
`remote broadcasting site. Alternatively,
`
`the invention
`
`utilizes a video tape player,
`
`a video disk player, or a
`
`computer-based digital video recorder, as the video signal
`
`source unit.
`
`The video signal source unit may be located
`
`in the same subway car as that
`
`in which the monitor or
`
`10
`
`monitors are located, or in adjacent or remote cars of the
`
`same train, with the necessary operative connection between
`
`the player and the monitor(s).
`
`An individual
`
`subway car
`
`can be equipped with its own video signal
`
`source unit,
`
`connected to a plurality of monitors mounted at different,
`
`15
`
`appropriately chosen locations along the length of
`
`the.
`
`subway car. Alternatively, one central video signal source
`
`unit
`
`can be
`
`located in one car of
`
`subway train,
`
`and
`
`connected to monitors in some or ali of
`
`the cars of
`
`the
`
`train,
`
`to provide a central video signal source unit for
`
`20
`
`the train.
`
`Computer
`
`(PC)
`
`based digital video recorders
`
`basically transmit video signals from a hard drive or CD-
`
`ROM storage.
`
`They are however also capable of receiving
`
`25
`
`transmitted input at intervals, e.g. news item updates, at,
`say, hourly intervals,
`to add to their stored transmittable
`video data.
`In this sense they also act as television
`
`receivers.
`
`
`
`30
`
`.
`
`The video signal source unit and video display
`
`monitors used in the present
`
`invention can be of known,
`
`Standard form, obtainable as off
`
`the shelf
`
`items
`
`from
`
`manufacturers and sales outlets.
`The connections between
`them, for display of televised material, are also standard~__
`
`Dye
`
`
`P. 12
`
`

`

`5
`
`
`
`
`and well within the skill of the art.
`For example, use can
`be made of
`the existing subway infrastructure by which
`audio
`announcements
`are
`currently
`transmitted.
`
`Alternatively,
`
`the connections may be by use of coaxial
`
`cables,
`
`fibre optics, cell phone
`
`systems or satellite
`
`transmission, or by other appropriate means.
`
`10
`
`15
`
`A preferred system according to the invention is
`
`a subway car or plurality of subway cars equipped with a
`
`especially LCD-based
`television monitors,
`plurality of
`television monitors, and a video signal source comprising
`
`a video tape player, video disk player or computer-based
`
`digital video recorder,
`
`the video signal source and the
`
`monitors being interconnected by suitable electrical cable
`
`systems which are self-contained within the subway car.
`
`In
`
`new subway cars can be built with the video
`this way,
`system or parts
`thereof
`installed,
`and
`usable
`on
`substantially any transit system, since the operation of
`the video system is independent of any previously installed
`
`20
`
`track,
`
`tunnel or control systems.
`
`The
`
`video
`
`system according
`
`to the present
`
`invention provides a means for communicating a very. wide
`range of information to viewers in an environment
`ideally
`suited to communicating short video messages to viewers,
`
`25
`
`especially commercial messages or
`
`sponsored community
`
`service, or informational news bytes. Most
`
`subway rides
`
`are of short duration, e.g. 15-30 minutes or less.
`
`It is
`
`normally undesirable to play television programs of any
`
`30
`
`Significant
`
`length to subway passengers
`
`for
`
`fear of
`
`distracting them from their proper points of
`
`interchange
`
`and disembarkation on the subway system.
`
`However,
`
`the
`
`system according to the invention is ideally suited for
`
`displaying a
`
`series of
`
`short,
`
`30
`
`second -
`
`1 minute

`bots

`
`messages,
`
`in sequence,
`
`such as
`
`a series of
`
`commercial
`
`messages. These can range from straightforward advertising
`as seen on commercial television, or the type of news feed
`with corporate sponsorship as
`seen by cable television
`
`viewers, with mews
`
`services provided by
`
`specialized
`
`companies
`
`in’ this . business.
`
`If
`
`the
`
`information is
`
`delivered by video tape player, video disk player or
`
`computer-based digital video recorder, it can be repeated
`at intervals of, say, 5-15 minutes, based upon the average
`duration of individual subway rides, i.e.
`the pre-recorded
`
`program is of total duration of about 5-15 minutes.
`
`If the
`
`feed is delivered from an outside source,
`
`its delivery
`
`depends on the package of
`
`the server,
`
`and according to
`
`agreement between the purchaser
`
`and
`
`the mass
`
`transit
`
`management, and other interested parties as necessary.
`
`Typically,
`
`the television images displayed by the
`
`monitors of the system according to the invention do not
`
`though they may contain rolling script,
`incorporate sound,
`similar to cable television news channels, or similar to
`closed-captioning for the hearing impaired.
`This avoids
`risk of
`interference with announcements being played to
`
`passengers through the normal audio address system carried
`by the subway train, and avoids adding to the general noise
`level experienced by passengers on the subway cars, a noise
`level which is commonly quite high even under normal
`running conditions.
`However,
`sound may be incorporated
`where appropriate,
`for
`example
`in safety or
`emergency
`situations, or to mark the beginning of a message to which
`
`the
`
`subway or
`
`transmission provider wishes
`
`to call
`
`attention.
`
`The manner
`
`in which the video display monitors
`
`are disposed and mounted in the subway car depends to some
`
`ote
`
`
`P. 14
`
`

`

`
`
`extent on the design of
`
`the subway car
`
`itself.
`
`Such
`
`designs
`
`can
`
`vary
`
`between different
`
`subway
`
`systems.
`
`Normally from 6-12 such colour monitors are provided in
`each subway car, suitably of 12"-13" size, spaced along the
`
`length of the car, and disposed above the windows of the
`car,
`in a manner and at a location which does not interfere
`with the operation of any other essential element of the
`car
`(door operation,
`lights, heating, air conditioning
`
`etc.). A subway car is normally constructed so that it has
`
`10
`
`a cavity wall, defined between its outer structural shell
`
`and its inner lining wall,
`
`the cavity providing for wiring
`
`and cables and other mechanical functions, and, at places,
`containing insulation.
`The video display monitors in the
`system of the invention are suitably mounted in the cavity
`
`15
`
`wall.
`
`In a preferred arrangement,
`
`the video display
`
`monitors have a strong metal frame construction,
`
`fixed to
`
`the frame of the subway car.
`
`The screens are preferably
`
`20
`
`e.g.
`unit,
`transparent
`rigid
`covered with “ a
`polycarbonate,
`shaped to coincide with the shape of
`
`of
`the
`
`internal wall of
`
`the
`
`subway car at
`
`the
`
`location of
`
`mounting.
`
`For example, when the monitor is mounted at the
`
`junction of the wall and ceiling of the subway car, where
`
`25
`
`there is commonly provided a concavely curved segment of
`
`internal wall,
`
`the transparent cover unit
`
`is suitably
`
`Similarly concavely curved, so that it can be mounted as a
`continuum with the internal walls and blended to contours
`
`thereof, with the monitor mounted behind it. The screen is
`

`
`suitably angled downwardly, for best viewing by passengers
`
`seated opposite the screen.
`
`The entire structure of
`
`the
`
`monitor,
`
`including the cover unit

`and colours of the subway car interior.
`
`the
`The video monitors used in the system of
`invention can be of standard, cathode ray tube-
`present
`basea design.
`Such monitors have the advantage of economy,
`being mass-produced items manufactured on a very large
`scale.
`They are eminently suitable for use
`in most
`embodiments according to the invention, and can be viewed
`clearly from a variety of angles. However,
`in circumstances
`where the subway car in operation encounters locations of
`large magnetic field,
`it
`is possible’ that
`the picture
`displayed on a CRT monitor will be distorted as the monitor
`moves
`through such location.
`Any such distortion effect
`can be reduced by surrounding the monitor,
`to an extent
`practical and consistent with its provision of full visual
`display, with an appropriate shield such as a steel or
`other ferromagnetic casement. Where such a magnetic field
`problem turns out
`to be particularly acute,
`the CRT-type
`monitor may be replaced by a monitor incorporating a colour
`liquid crystal display (LCD) screen, which is not sensitive
`to intermittent encountering of external magnetic fields.
`
`the present
`Specific preferred embodiments of
`invention are illustrated in the accompanying diagrammatic
`
`drawings in which:
`

`
`They are thus disposed opposite to

`sets of inward facing seats 16, and angled downwardly for
`ease of viewing of passengers 24 seated in such inward
`facing seats 16,
`as shown in Fig. 2, with direct sight
`
`lines 26, but visible to passengers seated elsewhere, and
`
`standing in the car 10. A video player23 is suitably
`located in the driver's cab 27 (Fig. 1A), and connected to
`
`all the monitors 22 by cables (not showing) disposed in the
`
`cavity walls of the car.

`
`Fig.
`
`3
`
`shows
`
`a detail of
`
`the car 10, at
`
`the
`
`location where a monitor 22 is to be installed.
`
`The car
`
`wall has
`
`an outer
`
`shell
`
`28
`
`in which windows
`
`14
`
`are
`
`sealingly mounted,
`
`and structural pillars 30 mounted at
`
`15
`
`intervals and secured to the vertical structural member 32.
`
`Centrally secured to the exterior skin and body structure
`of body 34 of the car is a main air duct 36 and a housing
`38 carrying ceiling lights running substantially the full
`
`length of
`
`the car 10.
`
`The
`
`space between the ceiling
`
`20
`
`housing 38
`
`and the top of
`
`the pillars 30
`
`is normally
`
`occupied by back lit advertising panels 40.
`
`Removal of
`
`appropriate portions of these panels 40 provides space for
`location of video monitors 22, according to the preferred
`
`embodiment of the invention.
`
`25
`
`Thus as shown in Fig. 4,
`
`the video monitor 22 is
`
`enclosed and rigidly mounted in its own enclosure 42, of
`
`The enclosure
`stainless steel, rigid plastic or the like.

`
`22A which is of
`
`thin,
`
`rectangular
`
`cross-section,
`
`and occupies
`
`less space
`
`in the ceiling
`
`structure of the car. Accordingly, it can be moved towards
`the ceiling so that
`its viewing screen is substantially
`flush with or even behind the light panel 40. This use of
`
`15
`
`an LCD-based monitor gives a better aesthetic appearance to
`the inside of
`the subway car as
`a whole,
`as well as
`improving
`the display performance

`and illustrates a means and
`the Toronto Transit System,
`location for mounting the video monitors in such a system.
`Details of construction, and hence details of appropriate
`mounting for video monitors may differ from subway system
`
`to subway system according to the form of car in use.
`
`Such
`
`mounting details do not depart
`
`from the scope of
`
`the
`
`25
`
`present
`invention.
`In all cases, it is contemplated that
`a plurality of monitors will be provided in each car, each
`rigidly mounted at a convenient location clear of the doors
`
`and windows, and at a disposition where it can be viewed by
`
`passengers riding the subway car, without difficulty.

`provision of
`
`such video monitors mounted in their own
`
`enclosures

`as
`
`described
`
`herein,

`faced with
`
`a
`
`transparent screen of,
