Definitions

  • the present invention relates to a method for providing broadcasting programs and an apparatus for the same adapted to assure a minimum interval between broadcasts of commercials and to a computer-readable storage medium storing programs or data to implement the above method and a device in order to run programs and commercials in a manner that broadcasting matches momentarily changing requirements in terms of time, place and kind of information to be supplied on a user side in terrestrial digital broadcasting and/or satellite digital broadcasting in which ordinary programs and/or commercial programs are broadcast.
  • a service of broadcasting in which a CM is selected or run in a manner that it can meet tastes of a user or be suitable to present/current conditions (time and/or places) of the user, that is, when the user takes part in a sport, a CM related to sports is run, when the user wants to have a meal, a CM related to meals such as restaurant information is run and when going for shopping, a CM related to shopping is run, or a like.
  • this method is called PUSH-type information delivery technology, which is widely used as an information delivery service in which information can be selected or rejected depending on the tastes of the user of the Internet, though it cannot yet provide the information to be able to meet such conditions designated by the user as time and/or places.
  • PUSH-type information delivery technology which is widely used as an information delivery service in which information can be selected or rejected depending on the tastes of the user of the Internet, though it cannot yet provide the information to be able to meet such conditions designated by the user as time and/or places.
  • POINTCAST is a typical company which provides information service by using such PUSH-type information delivery technology (refer to home page address: www.pointcast. com) .
  • POINTCAST network system is so devised that, the user who has registered, in advance, type of information that the user wants to get, can access to a WWW (World Wide Web) server on the Internet with proper timing (for example, every one hour, once a day or the like) to automatically obtainlatest information from the WWW server and to display it on a screen of a PC (Personal Computer) on the user side.
  • WWW World Wide Web
  • PC Personal Computer
  • the PUSH technology allows the user to automatically and one after another, obtain information that the user wants to get. Though a way of receiving the information is seemingly the same as in the case of television which provides information one-sidedly to a viewer, it differs greatly in that television provides information to many and unspecified persons while the POINTCAST network provides only information that the user wants to obtain. That is, the POINTCAST network allows the user to obtain, free of charge, information including news, weather forecasts, stock prices or the like which are customized to suit the user.
  • this service is available only when the user accesses to the WWW server on the Internet. If the user uses this service by a portable cellular phone in a car or somewhere, he/she must bear phone charges in addition to an Internet fee.
  • a two-way communication is a prerequisite for a PUSH-type information delivery service. Therefore, seemingly, such communication media as broadcasting which transmits information one-sidedly from a broadcast station to a receiver is unable to provide the PUSH-type information delivery service as described above.
  • the present inventor has invented a method for providing the PUSH-type information delivery service even through media transmitting the information one-sidedly.
  • CMs are fed, in advance, to the receiver which then stores received CMs.
  • the receiver takes out a proper CM and inserts it into an ordinary broadcasting program and then regenerates the inserted CM.
  • CM delivery that can meet tastes of the user or that can be made at a time when the user wants or at a place where the user wants is made possible.
  • Service of this kind is not yet available actually, however, technology related to this method is disclosed in Japanese Patent Application No. Heill-263058 as "Device for transmitting and receiving on-demand type radio broadcast for car user and method for the same" applied by the present inventor and still pending.
  • the device and method disclosed therein can be used in following states: When an advertiser is, for example, a manager who runs a restaurant being operated along a highway, the advertiser wants to run CMs related to the restaurant to drivers of vehicles and trucks which are running on the highway and coming near the restaurant.
  • the manager thinks that, by doing this, excellent advertising effects can be obtained and requests that a broadcaster delivers the CM in a PUSH-type service manner to the driver.
  • the broadcaster runs customized programs including the CM for the driver through the device for transmitting and receiving on-demand type radio broadcast in a state that the time, place and contents of required information change every moment.
  • the CM is chosen or rejected depending on tastes of the user or on conditions of time and/or places on the user side, there may be cases where some CMs are not chosen and not broadcast at all.
  • This situation is favorable to the user of CMs because he/she can obtain only specified CMs at_the time when he/she wants to get or at the place where he/she wants to get, however, this situation is not acceptable to a sponsor who must pay an advertisement fee for the CMs.
  • a broadcasting program providing apparatus for delivering a broadcasting program in a manner that broadcasting matches momentarily changing requirements in terms of time, place and kind of information to be supplied on a user side in a case of a driver operating a moving automobile including:

  • Necessary data read from the storage medium 37 is fed to a broadcasting program storing section 1 when the broadcasting programs and CMs are broadcast.
  • Data or programs stored in the storage medium 37 may be installed into other personal computers having similar CPUs to achieve a broadcasting system of the present invention.
  • a program used for selection of the broadcasting interval guaranteed-type program and for operations of the broadcasting program regenerating device 35 can be stored into the storage medium 37 through control of the CPU 34.
  • a similar system as shown in Fig. 9 can be mounted to a device of Figs. 1 and 6 in a same manner.
  • CMs can be run a number of times that a broadcaster has contracted with a sponsor to run and an interval between broadcasts which has been guaranteed to the sponsor can be assured.
  • This enables the broadcaster to guarantee broadcasting of CMs at an individual audience level to the sponsor.
  • a method presently available to know how CMs are recognized by an individual audience is to use an audience rating calculation based on a sample population. Since WWW, satellite digital broadcasting, ITS broadcasting or the like are used, the device and method of the present invention assure that CMs reach 100% of an individual audience, which can provide great advantages to the sponsor.
