`
`CLAIMS
`
`1. A method of coordinating and controlling television sets or cameras in a digital
`
`information system for exposing information on at least one display device through the medium
`
`of at least one television set or camera, characterized in that it comprises the following steps:
`
`generating an exposure list comprising control
`
`instructions
`
`for coordinating and
`
`controlling television sets or cameras with regard to what shall be exposed, when it shall be
`
`exposed, where it shall be exposed and for how long it shall be exposed;
`
`using a control center for coordinating and controlling television sets or cameras, wherein
`
`the control center is able to create and update said exposure list in real time with control
`
`10
`
`instruction fields via dynamic booking of information in time for exposure from mediators; and
`
`wherein the exposure list enables each television set or camera to be controlled,
`
`independently of other television sets or cameras, to receive the same or different information
`
`in accordance with the exposure list for exposure of respective television set or camera through
`
`the computerized devices.
`
`15
`
`20
`
`25
`
`2. A method according to claim 1, characterized in that information mediators are
`
`connected to a computerized control center via interfaces for data and telecommunication for
`
`round—the clock transmission of information, wherein the control center has communication
`
`interfaces against computerized devices, situated at specific places remote from the control
`
`center having drive routine means, which may be transparent for transmission of information
`
`with the drive routine means of the control center for transmission of information in the system
`
`via interfaces.
`
`3. A method according to claim 2, characterized in that a system administrator is able to
`
`update the exposure list with elective information at any time whatsoever, wherein the dynamic
`
`booking can be changed or delayed.
`
`4. A method according to claims 1—3, characterized in that a server situated at a specific
`
`place and being included in a computerized device comprises databases; and in that information
`
`in the databases relating to exposures in the exposure list is copied in databases of servers in a
`
`selected number of computerized devices situated at some other place.
`
`5. A method according to claims 14, characterized in that the exposure list includes
`
`3O
`
`reserved instruction fields for updating control instructions via mediator interfaces.
`
`6. A method according to claims 1- 5, characterized in that the control instructions are
`
`placed in a queue, or line, when the exposure list temporarily lacks instruction updating fields.

`

`

`23
`
`7. A method according to Claims 1-6, characterized in that a switch senses when one of
`said servers is out of function, wherein the television set or cameras controlled by said server
`
`are controlled by another server situated at some other place.
`
`8. A method according to any preceding Claim, characterized in that every television set
`
`or camera is assigned an unique address.
`
`9. A method according to Claim 8, characterized in that the addresses are of the type
`
`TCP/IP.
`
`'
`
`10. A method according to any one of Claims 8 or 9, characterized in that the addresses
`
`to television set or cameras, respectively, are stored on a smart card which can be read by
`computerised means via in these comprised smart card readers.
`
`10
`
`11. An arrangement for coordinating and controlling television sets or cameras in a digital
`
`information system for displaying information on at
`
`least one display device through the
`
`medium of at least one television set or camera, said information being supplied by mediators
`
`of information, for exposure or display , characterized in that it comprises:
`
`computerized control center means, wherein the control center has communication
`
`interfaces against;
`
`computerized means for coordinating and controlling television sets or cameras;
`
`exposure handler means whereby the control center functions, in real time and through the
`
`medium of said exposure handler,
`
`to create and update an exposure list having control
`
`instruction fields, via dynamic booking of display information from mediators; and
`
`wherein said exposure list, containing control instructions, coordinates and controls the
`
`television sets or cameras in question with respect to what shall be exposed, where it shall be
`
`exposed, when it shall be exposed, and for how long it shall be exposed, and enables each
`
`television set or camera, independently of other television sets or cameras, to receive the same
`
`or different information according to the exposure list for exposure, or display, by respective
`
`television set or camera through the computerized devices.
`
`12. An arrangement according to claim 11, characterized in that said mediators are .
`
`connected to the control center means via interfaces for data and telecommunication for
`
`transmitting said information at any elected time whatsoever.
`
`13. An arrangement according to claim 12, characterized in that said mediators posses
`
`drive routine means, said drive routine means possibly being transparent for transmission of

`
`information with the drive routine means of the control center for transmission of information
`
`in the system via interfaces for that purpose.
`
`14. An arrangement according to claim 11-13, characterized in that
`
`the system
`
`administrator is able to update the exposure list with elective information at any time whatsoev-
`
`er, wherein the dynamic booking can be changed or delayed.
`
`15. An arrangement according to claims 11-14, characterized in that a server situated at a
`
`specific place and included in a computerized device includes databases; and in that
`
`information in the databases relating to exposures in the exposure list is copied into databases
