fig1 shows a system in which the method of the invention is used . the figure shows the functional elements of the system , without showing all physical elements . the system serves to make a variety of services available to a large number of end users from a central point . examples of such services are the showing of a video film as demanded by a user , i . e . the so - called video - on - demand service , electronic shopping , and supplying travel information . the system 100 comprises a central station 102 , referred to as a server , and a user station 106 which is connected thereto via a connection 104 . the server can virtually simultaneously serve a large number of user stations by way of switching means 108 . the server comprises a memory 110 which stores inter alia the information which can be supplied to a user , for example said video films . the information can be stored therein in various ways and in various formats . video films may be stored , for example on a compact disc , tape or a hard disc and may be present in various formats , such as analog , digital , mpeg . the server also comprises a control unit 112 for controlling the connection of the user station and for dispatching the information to the user station . the user station comprises a display screen 114 , a sound reproduction device 116 , a receiver 118 for receiving user commands , and a control unit 120 . the display screen 114 and the sound reproduction device 116 may be integrated as a standard television receiver . the receiver 118 may be constructed as an infrared receiver for the reception of signals from a remote control , but also as a connection unit for a mouse or another control means . the operation of the system can be described in general as follows . after having started the user station , a user selects a given service from the current possibilities being offered . this offer is displayed on the display screen by way of a menu system which operates according to the method of the invention and which will be described in detail hereinafter . after the user has made a selection , for example a selection to watch a given video film , the server will offer the relevant service , i . e . it will transmit the video film to the user station via the connection 104 . because the services to be offered by a server are regularly extended and renewed , the menu system of the user station should also be regularly updated . to this end , a given embodiment of the system is organized so that the server dispatches the menu system to the user station during the starting of the latter . this results in a flexible organization in which the menu system can be regularly updated in a central location , the newest version of the menu system nevertheless being present in the user stations . in another embodiment , the menu system is already present in the user station upon starting , for example on a disc inserted therein at an earlier instant . two - way traffic exists on the connection 104 . from the user station commands are applied to the server to request given data , for example given video information and images for the menu , and to select and control a service , for example inserting an intermission in a video film . a variety of data , often consisting of audio and video information , is applied from the server to the user station . the connection can be realised in various ways . in a given embodiment an existing telephone mains is chosen , utilizing so - called asdl ( asymmetric digital subscriber loop ) modems . a network comprising coaxial cables or fibre optical cables , however , is also feasible . the display screen 114 can be realised in various appropriate ways . the display screen 114 shown may consist of two different sections , one section being used to display the menu systems with the options , whereas the other section is used to display images associated with the service . the display screen can be constructed as a cathode ray tube , a screen based on an lcd technique , with symbols composed of led or lcd segments , or in another manner enabling the reproduction of the relevant information . fig2 shows a given part of a menu system in which the method of the invention is used . in this part four options wherefrom a user can choose are displayed . an option represents a service which can be offered to the user . in the example shown in fig2 an option is displayed as a symbol characterizing the service it represents . this makes it easier for a user to select the service , but it is not an essential aspect of the invention . it is alternatively possible to display an option as a description of the associated service , as a short code or in another manner . the example shown in fig2 concerns services for the supply of video films , music clips , travel information and nature documentaries , represented by the options 202 , 204 , 206 and 208 , respectively . in conventional menu systems operating with such options the user designates a desired option and selects it . to this end , the user utilizes a control means , for example a mouse or a joystick whereby the user displaces an indicator , also referred to as a cursor , across the screen . the user positions the indicator on or near the desired option and affirms the selection by depressing a control . notably the necessity of actively positioning the indicator is problematic to many users of these conventional systems . in a menu system in which the method of the invention is used , the menu system successively makes one of the options available for selection and the user affirms a proposal by depression of the control . therefore , the user need not actively designate an option , since this is done by the menu system and it suffices for the user to express affirmation . in the example shown in fig2 first the system is enabled for some time for the selection of the option 202 , subsequently for the option 204 , then for the option 206 and finally for the option 208 . a user selects a given option by depressing the control at the instant at which the system is enabled for the selection of the relevant option . in one application of this method , the system is enabled for the selection of a given option for approximately 15 seconds . a shorter or longer period of time is also possible and the actual duration is not an essential aspect of the invention . in practice a period of time will be chosen which suits the circumstances in which the user selects an option . in order to inform the user of the option for which the system is enabled , this option is visually emphasized . emphasizing can be realised in various ways : showing an arrow near the option , making the option flash , inserting a halo around the option , and in many other ways . a given version of the system of the invention utilizes a text arranged in the option for the selection of which the system is enabled . fig3 illustrates , by way of example , how the option for the selection of which the system is enabled is emphasized in a system utilizing the method of the invention . it concerns a combination of highlighting of the option and insertion of a short text in the option . the symbol 304 in the figure illustrates the appearance of the option 204 when the system is enabled for the selection of this option . the user affirms the selection of a given option by depressing the control at the instant at which the corresponding option lights up . when the user depresses the control in the case shown in fig3 the system will start the service of delivering music clips . if a user does not select any option , after the last option 208 the method of the invention will enable the system again for selection of the first option 202 and subsequently the other options again . this cyclic mode of operation is not a requirement of the invention , and other sequences are also feasible . a reciprocating sequence could be adhered to , i . e . after the last option the last option - but - one again , and so on back to the first option , but an entirely different sequence is also feasible . the cyclic mode of operation offers a user - friendly organization : should the user miss an option , he will be given another opportunity and , because the actual sequence of presentation of options remains the same , the user can simply see an option coming up . in a given alternative version of the method of the invention , further information is given as regards the service which can be selected . this further information may be given in the form of images displayed on the display screen 200 , but also in the form of sound reproduced via the sound reproduction device of the user station . in fig3 for example segments of the newest music clips which can be offered via the relevant service are displayed in the window 310 on the display screen 200 . instead of being displayed in a separate window , the images can also be displayed on the display screen 200 as a background . such further information can be updated program - wise when the relevant service is modified . it may concern , for example a change of the contents of a service , such as the above newest music clips , but it may also concern an extension of services to be rendered , for example the possibility of reserving seats for concerts . the menu system utilizing the method of the invention may consist of several option selection levels . if the option 202 is selected in fig2 being the service involving the supply of video films , at the next level the user may be requested to select a given category of film . by way of example , fig4 shows the display screen after the selection of the option 202 by the user and the starting of the relevant service by the system . the options shown on the display screen in this case represent film categories wherefrom the user can select . in the present example , the option 402 represents action films , the option 404 represents comedies , the option 406 represents mysteries and the option 408 represents miscellaneous . a selection is made in exactly the same way as described with reference to fig2 . additional information can again be displayed in a window 410 , for example the top five films of the option for the selection of which the system is enabled . such subdivision into levels can be continued until the service to be supplied has been sufficiently defined . for example , after selection of a given film category , the next level may be the display of a list of films available in the relevant film category and after selection of a film from this list the selected film can be shown to the user . in a given embodiment of the system a user can deviate from the predetermined sequence in which the system is enabled for the options . in this embodiment the user has a control means whereby he can displace an indicator across the screen , thus designating a given option . this designation enables the system for selection of the relevant option . the relevant option can be selected by the user by depression of the control . such designation and selection of an option under the control of the user is a suitable facility for experienced users who wish to make a direct selection from the services offered without requiring a further explanation . fig5 shows a menu system in which all options are not simultaneously shown on the display screen . in this case the space available on the display screen 500 is insufficient for simultaneous display of all options . in order to offer the user a choice from all options in this situation , the options are displaced horizontally across the screen . for the description of the following example the options are chosen to move from right to left . however , mutatis mutandis the principle can also be used for motion from left to right . the options of the group 512 are visible on the display screen at this instant ; the option 514 has recently been visible and now moved away , and the option 516 will be displayed on the display screen to replace the option 502 when the latter is shifted away . the numbers 502 - 510 indicate fixed positions on the display screen in which each time a next option is shown . the options can again be linked so as to form a cyclic series , so that in the course of time the options disappearing from the display screen at the left - hand side enter the screen again from the right - hand side . one of the options in the group 512 is the option for the selection of which the system is enabled and is characterized as such . a symmetrical set - up can be chosen in this respect , this option then being present in the position 506 at the centre of the group 512 . the number of options on the display screen for the selection of which the system has recently been enabled ( i . e . in 502 and 504 ) equals the number of options for the selection of which the system will be enabled in the near future ( i . e . in 508 and 510 ). alternatively an asymmetrical set - up can be chosen , the option for the selection of which the system is enabled then being present in the position 504 or the position 502 . in the case of the latter set - up there are more future options to be seen than past options , which may be more compatible with the user &# 39 ; s needs in given circumstances . the future options are comparatively new and require more attention than the past options which have already been displayed on the display screen for the duration of a number of shift operations and which , moreover , cannot be selected in the short term anyway .
