`MOBILE TELE-COMPUTER NETWORK
`FOR MOTION PICTURE, TELEVISION AND
`TV ADVERTISING PRODUCTION
`
`FIELD OF THE INVENTION
`
`The present invention relates to the field of communica-
`tions systems; more particularly,
`the present
`invention
`relates to mobile communications designed for advanta-
`geous use with motion picture, television and TV advertising
`production.
`BACKGROUND OF THE INVENTION
`
`Most area of corporate enterprise are rapidly advancing
`their productivity via the use of computer networking.
`Computer networking is the connecting of multiple com-
`puters into a common communication system so that infor-
`mation may be exchanged between them. Computer network
`technology is redefining the way corporate America works.
`Computers and networking are being converged, spawning
`a synergistic fusion between the two that is reshaping current
`understanding of computer functionality. The advent of
`mobile computing employing high powered full-featured
`laptop and notebook computers as replacements for conven-
`tional desktop computer systems has enabled the “virtual
`office” to become the fastest growing area of business “real
`estate”.
`
`Intranets have recently begun to replace traditional client-
`server private networks as the chosen preference for
`network-centric (group) tele-computing. An Intranet is a
`private computer network using public Internet TCP/IP
`protocols and designed to be the most efficient and easy to
`use network for sharing information and data, including text,
`image and audio. Intranets are relatively cheap, they can
`exploit Internet features including the ability to establish
`Web sites to disseminate information, and they use available
`browsers (e.g., Netscape) to search for information.
`The creative and commercial success of Motion Picture,
`Television and TV Advertising film production is dependent
`on the ability of the parties to communicate with their
`audiences. Likewise, the professionals engaged in the mak-
`ing of these films and TV shows would greatly enhance their
`efficiency and thereby reduce their production costs com-
`puter network technology into their work environment. Such
`technology may also improve prospects for more effective
`creative collaboration. However, there is currently no inte-
`grated and coherent mobile network computing technology
`that satisfies the needs of motion picture, television, and TV
`advertising production.
`Although historically slow in embracing new electronic
`techniques, film and TV production personnel have recently
`been awakening to the incredible benefits that accrue from
`incorporating networked computing into their work and
`lifestyles. Fueled by the escalating need for ever greater
`efficiency to reduce production costs, what is needed is to
`incorporate telecomputing into film and TV production.
`Furthermore, the realities of Motion Picture, Television,
`and Advertising film production demand a fail-safe reliabil-
`ity to any of the service areas that it depends on. Therefore,
`any solution that reduces production cost and increase
`efficiency cannot be implemented at the expense of reliabil-
`ity.
`The present invention provides a telecomputer network
`that satisfies the needs of the Motion Picture, Television and
`TV Advertising industry. The network may be used to
`increase efficiency, reduce production costs and enhance
`creative collaboration, while maintaining reliability.

`SUMMARY OF THE INVENTION
`
`A telecomputer network is described. The network of the
`present invention includes a wireless wide area network
`(WAN) comprised of a redundant digital microwave com-
`munication system. The network also comprises at least one
`mobile communication hub and a wireless local area net-

`
`DETAILED DESCRIPTION OF THE PRESENT
`INVENTION
`
`A mobile network for use is described. In the following
`description, numerous details are set forth, such as bit rates,
`distances, etc. It will be apparent, however, to one skilled in
`the art, that the present invention may be practiced without
`these specific details. In other instances, well-known struc-
`tures and devices are shown in block diagram form, rather
`than in detail,
`in order to avoid obscuring the present
`invention.
`
`Overview of the Present Invention
`
`A tele-computing network architecture is described. The
`network comprises a wireless local area network (LAN), at
`least one mobile hub, and a wireless wide area network
`(WAN) that includes a redundant digital microwave com-
`munication system. The mobile hub is in the form of a
`mobile vehicle (e.g., a van) and is configured to transfer
`information as a single nomadic transmission/reception
`point between the microwave communication system and
`the wireless LAN.
`
`In one embodiment, the microwave communication sys-
`tem transfers information using multiple relay stations via an
`ethernet packet switching protocol such as the IEEE 802.10
`protocol or the TCP/IP protocol used on the World Wide
`Web. By using the ethernet packet communication, multiple
`applications may access the microwave links at any one
`time. The wireless LAN also utilizes the ethernet protocol to
`transfer information.
`
`the wireless WAN of the present
`In one embodiment,
`invention operates as a private Intranet using the TCP/IP
`protocols of the Internet. Its user operation may be based on
`the platform independent, Graphical User Interface (GUI) of
`the World Wide Web (e.g., Netscape Navigator). By using
`Web browser software (HTML, VRML, Java language, and
`numerous audiovisual “plug-ins” developed for Netscape),
`the present invention may create an effective, efficient, and
`easy to use Web based graphical multimedia environment
`for the dissemination of information and data on a private
`intranet, such as one used by media production industries.

`Although the present invention is described with use of
`the TCP/IP Internet protocol, other protocols may be used.
`For instance, other protocols which may be employed by the
`present
`invention include asynchronous transfer mode
`(ATM), Internet Packet Exchange (IPX) protocol, Lotus
`Notes, SMNP, NNP, Multiple Internet Mail Exchange
`(MIME), IP (Internet protocol)—ATM, Web Network File
`System (WNFS), File Transfer Protocol (FTP), Fiber Dis-
`tributed Data Interface (FDDI), Reliable Multi-cast Transfer
`Protocol (RMTP), and Multiprotocol OVER ATM (MPOA).
`The wireless WAN is preferably a secure network. In such
`a case, software programs provide a secure “fire wall” to bar
`unauthorized entry from the public Internet. The present
`invention uses access codes and passwords to control access
`to data available through the network. In one embodiment,
`encryption is used on all data traffic between designated
`locations and our secured intranet servers and the high speed
`wireless digital network. Such security in the form of
`software is well-known in the art.
`
`In one embodiment, the existing Internet backbone may
`be employed, where necessary, for relaying data between the
`servers of system users and intranet servers that provide the
`gateway to the wireless network of the present invention.
`The integration wireless LAN ethernet technology with
`digital microwave relay stations provides broadband, high
`speed wireless connections between locations and fixed
`sites, which supports, for example, industries such as the
`Motion Picture, Television, and TV Advertising industries.
`The high bandwidth and fast data rate wireless mobility also
`enable a custom designed, fully integrated mobile computer
`network system.
`The present invention provides a unique telecommunica-
`tion system that is a comprehensive full-featured mobile
`Web-based intranet information management and commu-
`nication system supported by a broadband microwave net-
`work infrastructure.
`
`Exemplary Network System Embodiments
`
`FIG. 1 illustrates the network system of the present
`invention. Referring to FIG. 1, the system 100 of the present
`invention comprises a private digital microwave network
`ring having multiple relay stations (hubs), such as exem-
`plary hubs 101 and 102. Hub 101 includes a wireless
`transmit/receive router 101B with its associated antenna
`101A and two transmit/receive relay components 101C and
`101B. The system also includes one or more mobile hubs,
`such as mobile hub 103, and one or more wireless local area
`network (LAN) 104. Note that in one embodiment, there is
`a mobile hub station supporting every wireless LAN.
`In one embodiment, each of the hubs are separated by 6
`to 10 miles and operate at 40-60 MHZ, which is much higher
`than fiber optics. In an alternative embodiment, the distance
`between hubs may vary to such distances as 25 miles. In one
`embodiment, each of the segments comprises a 20 Mbps
`bandwidth segment running in an 11 GHZ frequency band.
`Three such channels of 20 Mbps each can be combined to
`provide 60 Mbps of available bandwidth.
`In another
`embodiment, a single channel 100 Mbps bandwidth seg-
`ments (single antenna) are used. By using data rates of 60 to
`100 Mbps, the microwave ring accommodates transmission
`of high resolution video images directly from a digital post
`production house to a shooting location.
`The microwave ring employs system redundancy so that
`if one link is not functional, data may be routed in the
`opposite direction to arrive at its designated location. Using
`a spanning tree protocol, the system of the present invention

`determines the best route to send information on the fly to
`transfer information in the most efficient manner. This
`
`redundancy avoids the use of point to point parallel redun-
`dancy such as used by telcos to achieve the same affect.
`Thus, by using the microwave ring, the present invention
`provides telco independence.
`In one embodiment, for locations outside the coverage
`area of the wireless WAN, transmissions are relayed via a
`satellite communications like to the WAN. Note that the
`
`present invention may utilize fiber optic cable connections to
`connect signals to the nearest digital microwave relay sta-
`tion. In one embodiment, relay stations of the digital micro-
`wave system are connected to a fiberoptic SONET ring
`which provides additional bandwidth of up to 1 Gbps. In one
`embodiment, each of hubs 101 and 102 also includes out of
`band management 105 and 106, respectively, which coor-
`dinates telco access when the microwave ring cannot sup-
`port all of the transmissions because of limited bandwidth.
`Wireless LANs at individual locations are linked to the
`
`wireless wide area network (wireless WAN) of the present
`invention and the Internet backbone via multipoint wireless
`routers, such as routers 101B and 102B. In one embodiment,
`these routers, each capable of 10 Mbps data transmission
`operating at 2.4 Ghz with an omni-directional radius of 8/9
`miles and up to 25 miles with directional focus, will in turn
`be connected to a series of strategically placed digital
`microwave relay stations of the wireless WAN. In one
`embodiment, a 10-100 Mbts ethernet switch is located at
`each microwave site to serve as a bridge between the
`wireless downlink to the remote location and the microwave
`backbone.
`
`In one embodiment, the LAN 104 is a wireless ethernet
`LAN connecting multiple remote personal computers (PCs)
`as nodes. In one embodiment, the LAN 104 covers an “on
`site” radius of up to 1/2 mile at 2 Mbps from a mobile hub
`station, strategically placed at the designated location, such
`as mobile vehicle 103. For instance, the LAN 104 may be at
`the production’s location LAN to service the location tele-
`computing communication needs of a film or TV production
`unit, even when shooting on a stage or studio lot.
`In one embodiment the LAN is secure. The LAN may
`employ standard encryption or logging on security. In an
`alternate embodiment, the LAN includes video conferencing
`capabilities.
`In one embodiment, the LAN 104 transfers data to mega-
`bits per second to a single point, which is the mobile hub
`station such as the mobile vehicle 103 described below. In
`one embodiment,
`the mobile hub station is housed in a
`custom fitted motor home (e.g., vehicle, van) that not only
`links the location LAN 104 to the Internet backbone via the
`
`microwave ring (i.e., the wireless
`One or more hubs of the microwave ring are equipped
`with microwave antennas configured to communicate with
`one or more of the mobile hub stations. At each hub, down
`linking to sites is possible via wireless communication
`without the use of telco. In one embodiment, the speed of the
`up link and down link of information is at 10 megabits per
`second. For instance, microwave antenna 101A communi-
`cates with mobile vehicle 103.
`
`When the mobile hub station has reached its location, its
`antenna is calibrated. In one embodiment, the calibration
`process is a line of sight process.
`In an alternate
`embodiment, the calibration process is not necessary where
`the mobile hub station includes an omni-directional antenna
`
`and is able to transfer information from a non-stationary
`position. In one embodiment, the mobile hub station only
`
`OOOOO4
`
`000004
`
`

`
`5
`transfers data from a stationary position. However, even
`though the transfer of data only occurs from a stationary
`position, the mobile hub station is in fact a nomadic vehicle
`that may be driven any where and can still gain access to the
`wireless WAN of the present invention. Thus, the mobile
`vehicle receives high bandwidth at a mobile location, avoid-
`ing reliance on existing cable sites.
`In one embodiment, the mobile hub station of the present
`invention includes a file server which accesses a proxy
`server. The server, such as server 103A, in each hub station
`is used to coordinate communication with a microwave
`
`antenna of a relay station, such as the microwave antenna
`101A. The server updates the server back at a home office
`(not shown) and operates in synchronization with the home
`office. The file server also employs file sharing and routes
`mail. The home office would have access to these records.
`
`In one embodiment, the mobile hub station also comprises
`a workstation viewing environment for broadband high
`resolution video location. The present invention provide a
`conduit infrastructure for internet information system man-
`agement interactive relay of broadband video in real-time
`and at full workstation resolution. In one embodiment, the
`workstation includes a high resolution progressive scan
`monitor.
`
`Note that the home office may coordinate all communi-
`cation over the telecomputing network of the present inven-
`tion. The home office includes a server to control commu-
`
`the
`nication with the entire system. In one embodiment,
`home office comprises a single master location. However, as
`bandwidth requirements increase, additional master loca-
`tions may be included in order to reduce overloading of
`segments on the microwave ring. These additional master
`locations may be interconnected by terrestrial-based high-
`band width fiber optic links to the master location.
`Software
`
`The present invention uses Web-based software applica-
`tions designed to facilitate information/data base organiza-
`tion and communication for the various areas of production
`specialization: directors; producers; cinematographers; edi-
`tors; script supervisors; art directors; assistant directors;
`production managers; location managers; casting directors,
`etc.
`
`In one embodiment, incorporated within its Web-based
`software applications, the service provides e-mail, down-
`loading or uploading files from the FTP sites and Internet
`Relay Chat (IRC), as well as video conferencing. The system
`of the present invention may also offer the latest develop-
`ments in “Web phone” voice communications and switch
`telephony from with the LAN to any phone using microcells
`in the LAN. This replaces conventional cellular phone
`connections and is seemlessly integrated with the Intranet’s
`multi-media environment.
`
`Acting as a “gateway” onto the full range of public
`Internet services, clients access any part of the Internet from
`their remote location nodes connected through one of a
`wireless LANs of the present invention, as well as from any
`conventional or cellular phone connection.
`In one embodiment, the Intranet database management
`may be implemented using an inter/intranet standard such as
`IIOP (Internet Inter Operable-ORB) based on COBRA
`(Common Object Request Broker Architecture) and DCOM
`(Distributed Common Object Model) using active X frame-
`work.

`the Digital Artist in the filmmaking process will become as
`routine and valued as that of the Cinematographer or Pro-
`duction Designer. The ability to do real time wireless relay
`of High Resolution digital film images from a graphics
`workstation direct to a shooting location will, for the first
`time ever, offer new dynamic possibilities for the Digital
`Artist to participate as an active crew member in location
`filming. A skilled Digital Artist, working along side the
`Special FX Supervisor, may help shape the way Directors,
`Cinematographers, Production Designers and Producers are
`able to integrate their ideas with ever expanding possibilities
`of digital technology. Having remote mobile access during
`the shoot to digital image processing via the broadband
`wireless relay network of the present invention combine
`traditionally separated production from postproduction.
`In one embodiment, X Windows running on a PC is used
`at a shooting location to enable remote user manipulation of
`an SGI workstation. CGI work in progress, designed as
`composite components for
`live action images, can be
`relayed in real time to the shooting location, thereby making
`CGI truly interactive with filming process. Virtual Sets that
`will eventually be composited with the final film image can
`be integrated as reference components into camera compo-
`sitions during live action shooting utilizing a high quality
`video assist.
`
`Digital animated multimedia storyboards that are capable
`of incorporating 3D spatial renderings can become valuable
`interactive tolls both for conceptual fine tuning and shot
`planning. Input from a variety of image sources, including
`photographic, graphic and CGI, both still and/or full motion,
`can be incorporated to generate a fertile environment facili-
`tating the creative process. These animated multimedia
`storyboards will be able function as evolving organic “docu-
`ments” during the entire production process helping to fine
`tune ideas and concepts between the director and his/her key
`collaborators.
`
`to production
`Any information or data relevant
`administration, e.g., story boards, scripts or script changes,
`production schedules, budgets, maps and directions, location
`photos, call sheets, casting information, payroll information,
`accounting reports, bulletins, personnel directories, vendor
`catalogues, etc., incorporating text, audio, image, video can
`be uploaded to the production company’s private intranet
`Web server resident at a central office(s) and accessed on
`demand by any authorized personnel regardless of their
`location. Even if a production member is outside the wire-
`less LAN/WAN Service Area, access to the private intranet
`may be made via any conventional public Internet connec-
`tion from anywhere in the world via a modem or ISDN
`terminal adapter.
`
`In one embodiment, the present invention allows a camera
`generated time code to link to the Web and network appli-
`cation servers of the present
`invention. This allows for
`productions to cross-reference and access to all relevant data
`(e.g., script supervisor notes and camera data) to specific
`scenes and takes via this frame accurate time code.
`
`Whereas many alterations and modifications of the
`present invention will no doubt become apparent to a person
`of ordinary skill in the art after having read the foregoing
`description, it is to be understood that the particular embodi-
`ment shown and described by way of illustration is in no
`way intended to be considered limiting. Therefore, refer-
`ences to details of the various embodiment are not intended
`
`to limit the scope of the claims.

`ABSTRACT
`
`A telecomputer network is described. The network com-
`prises a redundant digital microwave communication
`system, at least one mobile vehicle, and a wireless local area
`network (LAN). In one embodiment, the microwave com-
`munication system transfers information using ethernet
`packet switching. In one embodiment, the wireless LAN
`transfers information using the TCP/IP protocol. The mobile
`vehicle is configured to transfer information as a single
`nomadic transmission/reception point between the micro-
`wave communication system and the wireless LAN.
