Definitions

  • the invention generally relates to television broadcast sys- terns, and particularly to broadcasting television commercials between other programmes on a television channel.
  • the aim is to provide topical commercials and commercials customized for local or short campaigns, or to react quickly to the needs of an advertiser. A need has thus arisen for a technology that enables the cost- effectiveness and informative versatility of a television commercial to be enhanced.
  • An object of the invention is to provide a technology for broadcasting commercials to enable additional information to be added to tele- vision commercials.
  • the television commercial preferably comprises a prompt for a user to change over to a teletext mode or to a particular teletext page in order to obtain the addi- tional information relating to a commercial.
  • the invention thus enables various additional information to be readily provided along the television commercial film constituting the basic commercial.
  • the additional information may include changing information, such as offers, product information, address information or other contents that would not normally be included in the commercial film for one reason or another.
  • the commercials produced by an advertiser can thus be utilized in a more versatile and cost-effective manner.
  • the contents of the basic television commercial does not need to comprise all information; neither does the production unit have to produce several versions of the basic film.
  • the teletext advertising according to the invention enables the volume of spe- cial offer advertising to be increased since different offers can be added to the basic commercial for different campaigns.
  • the additional information can also be local, in which case teletext pages with different contents are broadcast along the basic commercial in different areas.
  • the contents of the teletext page broadcast along the commercial film may vary according to the broadcasting moment or another criterion.
  • the additional information is always broadcast on a particular teletext page or particular teletext pages whose contents are dynamically changed in dependence on the commercials broadcast on the television channels.
  • a small number of teletext pages is used for presenting the additional information of different commercials.
  • Additional information relating to a particular commercial session may exist on the pages e.g. only for the duration of a commercial film or a commercial break and possibly for a while after the commercial break. This enables a great amount of changing advertising to be implemented using a small number of teletext pages. In this manner, capacity is more effectively used than when a teletext page is permanently reserved for the additional information of each advertiser.
  • the teletext page containing additional information is a page to which a receiver directly changes over from a television programme or a commercial when the user activates the teletext mode by a predetermined button in a remote controller of the receiver.
  • This page is preferably a starting page or a basic page of a teletext service, displayed by default by a receiver apparatus when the user activates the teletext mode.
  • This starting page can be used for displaying additional information during commercials and possibly for a while thereafter; at other times, the starting page displays its ordinary contents, such as the main menu of teletext pages.
  • An example of such a starting page in the existing analogue television systems is page 100, to which the receiver changes over if not otherwise configured by the user.
  • the receiver may start the teletext mode from several alternate pages, depending on which predetermined button in the re- mote controller the user presses.
  • a starting page when the teletext mode is activated during commercials, a starting page will be opened which indicates which predetermined button in the remote controller of the receiver the user is to press in order to access the teletext page containing the additional information relating to a particular commercial.

  • Figure 2 illustrates a television screen displaying a television commercial
  • Figure 3 illustrates a television screen displaying a television commercial and a superteletext page containing information relating to the commercial
  • Figure 4 illustrates a remote controller of a digital television receiver or a Set Top Box
  • Figure 5 illustrates a television screen displaying a television commercial and a superteletext starting page having a link to a page containing additional information relating to the commercial
  • Figure 6 illustrates a television screen displaying a television commercial and a superteletext page containing additional information relating to the commercial.
  • the invention can be applied both in analogue television systems and in digital television systems comprising a teletext service.
  • the teletext system is used as an added value service, or supplementary service, which carries additional information through the television broadcast system.
  • teletext information is placed in a television signal. In fact, it is included among such video information that is not shown on a television screen, which is why the teletext information does not necessitate an additional bandwidth in the television system.
  • the teletext information is placed in the horizontal lines of a Vertical Blanking Interval (VBI) that do not show on the television screen. These horizontal lines are lines 6 to 22 and lines 320 to 335.

  • a teletext page generally refers to information contents to be presented on a television screen at one time.
  • the conventional teletext system supports 800 pages.
  • Each main page may comprise a number of sub-pages. For instance, an indication "2/4" may be shown at the upper part of the screen to indicate that the particular main page comprises four sub-pages and that the user is viewing the second sub-page.
  • the use of sub-pages enables the total number of pages to be increased; simultaneously, however, the pages are less frequently updated.
  • a conventional teletext page comprises 24 lines, each line comprising 40 characters. This only enables poor-quality graphics to be presented. Consequently, the existing information services are often text-based services.
  • the receiving end needs a teletext decoder to separate the teletext information from the received video information stream and to display the teletext information on the screen of a television receiver.
  • the teletext decoder is integrated in the television receiver.
  • the user can access a desired page by selecting a three-digit number by means of a control panel, usually a remote controller of the receiver.
  • the teletext decoder then separates the selected page from the received video information. After this short period of time, which is necessary for receiving the entire page, the teletext information (page) is presented on the screen.
  • a certain number of pages before and after the selected page is stored in the memory at the same time. If the user selects e.g. the next page, it can be read directly from the memory and presented immediately. This enables the delay necessary for receiving pages to be avoided and the browsing of the pages to be quickened.
  • the teletext decoder in modern television receivers stores at least a particular start- ing page or a page selected by the user in the memory already while in the television mode, in which case the starting page can be displayed on the television screen in the teletext mode without delay when the user activates the teletext mode.
  • FIG. 1 schematically shows an exemplary television sys- tern whereto the present invention is applied.

  • the updating unit 1 arranges the teletext pages in a desired order (1 to 800) in a carousel-type broadcasting buffer 2 provided with a location 2A for each page to be broadcast.
  • the carousel 2 "rotates", and a page to be broadcast is transferred to a combiner 5 to be inserted into the video information VIDEO, i.e. in the horizontal lines of the video signal, received from the unit 3.
  • the pages in the carousel 3 are thus broadcast in a fixed order.
  • the video signal generated by the combiner 5 is supplied to a television broadcasting unit 6 and the radio-frequency television broadcasting signal is broadcast through a broadcast network 7 to television receivers 8 and 9.
  • the teletext decoder separates the page selected by the user from the video information and displays the page on the screen.
  • the user controls the television receivers 8 and 9 by remote controllers 10 and 11.
  • the teletext system is arranged to broadcast additional information relating to a television commercial being broadcast substantially simultaneously.
  • This operation is coordinated by an appropriate control mechanism, which, in the embodiment of Figure 1 , is illustrated by a programme management unit 4.
  • the programme management unit 4 times the programme and advertising unit 3 to broadcast a particular television commercial, it also times the teletext unit 1 to simultaneously place additional information relating to the particular commercial in the carousel 2 in the location of a particular teletext page.

  • the additional information is always broadcast on a particular teletext page or particular teletext pages whose contents are dynamically changed in dependence on the commercials shown on the television channels.
