Definitions

  • the present invention relates generally to a method and a system for reliably and efficiently transferring information from one or more content providers to one or more information consumers.
  • a system with information i.e. a content provider
  • a content provider will usually want to be able to distribute the information in a simple and efficient manner.
  • Distributing information from one or more content providers to one or more information consumers traditionally involves a service provider.
  • a service provider provides a uniform interface for the content providers when they distribute information and also a uniform interface for all the information consumers for receiving purposes. All information is transferred via a service provider to ensure, for example, that the information has the right format for the information consumers.
  • Information can, for example, be audio, video or data, and take many different forms, for example in the form of music, advertisements, movies, electronic encyclopedias, books or magazines, or internet access.
  • a system utilizing such a distribution structure for projecting advertisements in subway stations is disclosed in WO 97/41546.
  • An object of the invention is to define a method for reducing the bandwidth requirements of a service provider.
  • Another object of the invention is to define a cost efficient information transfer system for presentation of information to one or more end users.
  • the aforementioned objects are achieved according to the invention by a method of redirecting the flow of information that previously just passed through a service provider, to be directly sent to information consumers without passing through the service provider, and a system carrying out the method.
  • the flow of information is redirected by a virtual service provider interface placed at a content provider in question.
  • the content providers with the virtual service provider interface will believe that they are communicating with the service provider and are sending the mformation there.
  • a content provider with a virtual service provider interface will not notice any difference.
  • a virtual service provider interface will preferably sort the traffic of information such that information intended for the information consumers will be transferred directly to the information consumers, i.e. directly without passing through the service provider, and communication with the service provider is directed to the service provider.
  • a virtual service provider interface can be implemented as pure software in a content provider, as a hardware add-on, or as a mixture, in dependence on the specific embodiment.
  • the aforementioned objects are also achieved according to the invention by a method of distributing information via a wireless transfer system, to be displayed at one or more information consumers, from one or more content providers by means of a service provider.
  • the method comprises a number of steps. In a first step the one or more content providers transfer communication to a service provider interface, the service provider interface being a virtual interface residing at a content provider in question. In a second step the virtual interface transfers information to the transfer system. In a third step the transfer system transfers information provided by the virtual interface to the one or more information consumers.
  • the method can advantageously in some versions further comprise the step of the virtual interface sorting the received communication into communication to the service provider and information to the one or more information consumers, and the step of transferring the communication to the service provider from the virtual interface to the service provider.
  • the transfer system can advantageously be either a broadcasting system transferring information by means of at least one transmitter, a multicast transfer system, or a point to point transfer system.
  • the broadcasting system is advantageously a digital audio broadcasting (DAB), a digital video broadcasting (DVB), or another type of digital broadcasting for use as an information transfer medium to the one or more information consumers.
  • the multicast transfer system is advantageously unified mobile transmission service (UMTS), GSM packet radio service (GPRS), or the like.
  • the information consumer can be a stationary or mobile receiver, or a stationary or mobile advertisement and information point.
  • the virtual interface transfers statistics to the service provider of information transfers between the virtual interface and the transfer system. The statistics can for example be used for billing purposes.
  • a system of distributing information via a wireless transfer system to be displayed at one or more information consumers, from one or more content providers by means of a service provider.
  • the system comprises a service provider interface, a first transfer means, a second transfer means, and a third transfer means to thus carry out the invention.
  • the service provider interface is arranged in at least one of the one or more content providers, the service provider interface being a virtual service provider interface.
  • the first transfer means being arranged at a content provider in question and arranged to transfer communication to the virtual service provider interface residing at the content provider in question.
  • the second transfer means being arranged in the virtual service provider interface and arranged to transfer information to the transfer system.
  • the third transfer means of the transfer system being arranged to transfer mformation provided by the virtual service provider interface to the one or more information consumers.
  • the system further advantageously comprises a sorting means and a fourth transfer means.
  • the sorting means being arranged in the virtual service provider interface and arranged to sort the received communication into communication to the service provider and information to the one or more information consumers.
  • the fourth transfer means being arranged to transfer the communication to the service provider from the virtual service provider interface to the service provider.
  • the transfer system can advantageously be either a broadcasting system transferring information by means of at least one transmitter, or a point to point transfer system.
  • the broadcasting system is advantageously a digital audio broadcasting (DAB), a digital video broadcasting (DVB), or another type of digital broadcasting for use as an information transfer medium to the one or more information consumers.
  • DAB digital audio broadcasting
  • DVD digital video broadcasting
  • the required transfer bandwidth at a service provider can be minimized by not transferring information to a service provider, which is not intended for it, by means of a virtual service provider interface.
  • Content providers will be able to distribute information to the intended one or more information consumers faster, i.e. without delay, as the information is not delayed by having to pass through, or be processed by, a service provider. Further, reliability is increased as the system does not come to a halt if the service provider of the system malfunctions.

  • Mobile information consumers can either be passing through an area of interest, be completely within the . area of interest for the complete route, or with just one end point within the area of interest and the route passing out of the area of interest.
  • the information can, according to one embodiment of the invention, be transferred to an information consumer by means of a broadcasting system using, for example, one or more transmitters.

  • An information consumer can also be seen as a user desiring information.
  • An information consumer receives information from a service provider.
  • a service provider can provide a part of the information but will commonly not generate any information itself.
  • a service provider is the central management point, which will properly logically direct information from an external source, a content provider, to an external destination, an information consumer.
