Description:
BACKGROUND OF THE INVENTION  
         [0001]    A. Field of the Invention  
           [0002]    The present invention generally relates to a service providing apparatus for identifying a desirable service to be provided to a user from a large number of provided services such as broadcasting programs in a cable television (CATV), an interactive television and the Internet Relay Chat (IRC), and to a service receiving apparatus, a service providing host, a computer-readable recording medium for storing a selected-service receiving program, a computer-readable recording medium for storing a selected-service transmitting program, a service selecting method in a service receiving apparatus, and a method for transmitting a selected service in a service providing host.  
           [0003]    More specifically, the present invention is directed to a service providing apparatus that is configured to select a service to be provided based on service utilization information of a plurality of users, a service receiving apparatus, a service providing host, a computer-readable recording medium for storing a selected-service receiving program, a computer-readable recording medium for storing a selected-service transmitting program, a service selecting method in a service receiving apparatus, and also to a method for transmitting a selected service in a service providing host.  
           [0004]    B. Description of the Related Art  
           [0005]    Conventionally, various services such as broadcasting programs of a CATV, and open channels for IRC are available for accessing and are typically selected directly by users. However, there are many services available, specifically, there are hundreds of open channels found in IRC and therefore, it is difficult for individual users to select desirable services. In particular, when first attempting to use such services, users have an extremely difficult time learning about even the most basic of the services available. This problem is especially acute when attempting to use IRC. The reasons for such problems are easy to understand. In the CATV, since the programs are determined before broadcasting the programs, the users may obtain information concerning programming by referring to a program table in order to select desirable programs. On the other hand, with reference to IRC, there are no such program listings available which reveal the contents of conversations in the IRC programs, even when the main subjects on open channels are pre-determined in advance.  
           [0006]    To solve the above-described difficulties which occur when a user attempts to select a service, for example, Japanese Unexamined Patent Application Laid-Open No. Hei 6-86279 discloses a home terminal system for CAM This CATV home terminal system allows the services to be classified according to the contents thereof and the users to designate the classification, so that the number of services displayed on the screen will be reduced. Also, Japanese Patent Application Laid-Open No. Hei 9-261609 discloses transmitting apparatus, receiving apparatus, and transmission/reception system for broadcasting program, in which the audience rating of programmed services is displayed, and the number of services is reduced to display on the screen in an order based upon increasing audience ratings. Furthermore, another system has been proposed, in which, while using specific phrases and theme music concerning in the contents of the services to be provided, specific services are selected from a large number of services, on behalf of users, and then the selected specific services are displayed on the screen. For instance, there is a system which allows a user to designate a keyword appearing in an open channel of IRC and produce a list of channels which include this keyword on the display screen.  
           [0007]    However, in such the systems as described in Japanese Patent Application Laid-Open No. Hei 6-86279 and Japanese Patent Application Laid-Open No. Hei 9-261609, when the users attempt to select desirable services, the number of services which will be displayed on the screen is slightly reduced so as to make the selection task a little easier. Further, in the conventional system where a keyword is designated the users, the users will have no chance to learn about such services that fall outside of the designated keyword.

The user data set  21  may include: selected service data, receiving apparatus data, user attribute data, and utilization place data. The respective data are previously inputted by, for instance, the user and stored in the user terminal by the input/output unit  26 . The selected service data is data indicative of at least one service (i.e. and IRC) which the user has logged onto or may want to log onto via the user terminal  3 , and the data includes, for instance, an address where the service is accessed, and the name of the service. The receiving apparatus data is data used to discriminate each of the user terminals  3  within the network  15  by the service selecting host  2 , and includes an address (i.e. an internet address) and a telephone number allocated to each of the user terminals connected to the service selecting host  2 . The user attribute data is data indicative of, for example, sex, age, occupation, and hobby of the user.  
         [0101]    As an example for the purpose of describing the present invention, two sets of user attributes, i.e., “a male in his twenties”, and “a single in his thirties” are to possible attributes assumed to be previously inputted and recorded in several user data sets, and classification names (or codes) corresponding thereto are employed as examples of user attribute data. As the utilization place data, for instance, the following detailed information is considered possible for use, an address of a user, a nationality of a user, latitude/longitude obtained from a GPS (Global Positioning System), and a name of a repeater station obtained from the PHS (Personal Handy phone System). In the description of the present invention, a classification of two sets of utilization places “KOBE CITY” and “suburb region” are used as examples, and corresponding classification names thereof are employed as the utilization place data. Other information in addition to the above-listed data may also be included in the user data set  21 , if required or desired.  
         [0102]    Selection Information  
         [0103]    The selection information  22  includes data transmitted from the user terminal  3  to the service selecting host  2  and is derived from the data combinations in the above described user data set. In the embodiment of present invention described herein, the selection information  22  used in the service selecting host  2  and the user terminal  3  is pre-configured as a plurality of sets of selection information which include data combinations based upon the information in user data sets from various individual users. For example, a user or group of users want to be directed to a chat or IRC using the follow designated sets of selection information:  
         [0104]    (1) The user(s) desires connection to the most popular selected service, where the popularity is based upon selected service data from subscribing user terminals;  
         [0105]    (2) The user(s) desires connection to a service that is both appropriate and popular of all selected services based upon identification of such a selected service by commonality between classification of user&#39;s attribute data and selected service data in the user terminals from subscribing user terminals;  
         [0106]    (3) The user(s) desires connection to a service that is corresponds to a particular location and is popular of all selected services based upon identification of such a selected service by commonality between the user&#39;s utilization place data and selected service data in the user terminals from subscribing user terminals.  
         [0107]    Furthermore, in the example described above, as is further described below, special channels 1 to 3 are subsequently identified by the service selecting host  2  where the special channels 1 to 3 correspond to channels provided in IRC. The special channels 1 to 3 correspond to services which were identified as a result of commonality between the various the above-explained selection information in a one-to-one relationship. Specifically, special channel 1 corresponds to the most popular selected service, special channel 2 corresponds to an identified service that is both appropriate and popular, special channel 3 corresponds to a service with a particular location and that is popular. The special channels are described in greater detail below. When one special channel is selected by a user from a user terminal, one of the above-explained selection information (1) to (3) is transmitted to the service selecting host, as is explained further below. The service selecting host  2  compiles and sorts the information on the basis of the respective selection information as described above.  
         [0108]    Structure of Service Correspondence Table  
         [0109]    In FIG. 3, there is shown a conceptional structural diagram of the service correspondence table  7  indicative of service utilization information.  
         [0110]    The service correspondence table  7  includes a transmission subject, a channel number, and a service name. For the purposes of providing an explanation of the present invention, it is now assumed that the service selecting host  2  has selected the most appropriate selected services for accessing from the user terminals based upon the above described selection information.  
         [0111]    In FIG. 3, mark “*” indicated in the column labeled Transmission Subject indicates that the corresponding service in that row is designated for use by all of the user terminals which subscribe to the service provided by the service selecting host  2 . In other words, no user data set information classifies these services. The service correspondence table  7  depicted in FIG. 3 is only one example of such a table and in the depicted example, only a small amount of services are listed thus reflecting usage of a select number user terminals connected to the network where the services listed were determined based upon user attribute data and utilization place data.  
         [0112]    In the column Transmission Subject, the rows having the subject “a male in his early twenties” and “a single in his thirties” each correspond to a service which was identified by sorting compiled information in the condition list  12 , where the sorting was effected based upon respective classifications in which user attribute data designated common information.  
         [0113]    For example, the row “a male in his early twenties” identifies an IRC or chat room which is most popular with users who have in their user attribute data the information that the user is “a male in his early twenties”. Similarly, the row having the Transmission Subjects “KOBE CITY” and “suburb region” correspond to chat room or IRC services that were sorted based upon the popularity of these services with users whose respective classifications in user attribute data and utilization place data had common information and where the utilization place data included information “KOBE CITY” and “suburb region”.  
         [0114]    Although not shown in FIG. 3, other Transmission Subjects may be identified based upon further combinations of sorted data obtained by searching and sorting combinations of information listed the condition list  12  in which information from the user data sets is compiled. For example, the following transmission subjects may also be identified by searching and sorting for combinations of information from the utilization place data with the user attribute data such as “a male in his early 20s, who lives in KOBE city”, and “a single male in his thirties, who lives in a suburb region”. In this case, in order to select a service suitable for such a transmission subject, common data is searched for and sorted based upon the information contained in the selection information.  
         [0115]    The rows with the listing Normal 1, Normal 2, . . . Normal 5 in the column with the heading Channel Number indicate normal IRC channels (Normal Channels). These normal channels are not sorted, but rather are indications of chat channels or chat rooms readily available on the network  15 . Although 5 sets of normal channels are depicted in FIG. 3, hundreds of Normal Channels are usually accessible in IRC over, for instance, the internet. In the normal channels, there is no classification of the normal channels and therefore, all user terminals are designated as the Transmission Subjects as indicated by the “*”, and a separate Service Name corresponds to each of the normal channels.  
         [0116]    In the Channel Number column, the channels “Special 1” through “Special 3” listed indicate special channels which have been identified by the service selecting host  2 . In the example depicted in FIG. 3, the Special 1 channel corresponds a channel that was identified in accordance with the above-explained selection information (1), where by searching and sorting through the data compiled in the condition list  12  from all of the user terminals, the most popular of all selected services has been identified. The two “Special 2” channels were identified by searching and sorting through the compiled data in the condition list  12  to find commonality between the above-described selection information (2), where the service was transmitted to a user terminals whose classifications in the user attribute data included the data identified in the corresponding Transmission Subject column. Similarly, the two “Special 3” channels corresponds to channels identified by searching and sorting through the compiled data in the condition list  12  to find commonality between the above-described selection information (3), where the service was transmitted to a user terminals whose classifications in the utilization place data included the data identified in the corresponding Transmission Subject column.  
         [0117]    It should be understood, that each user who logs onto the service selecting host  2  will be provided with a customized list of channels which may be selected for usage. For instance, a user whose user data set designates that the user is, for instance, in his early twenties and is living in Kobe City will be provided with at least the following special channels from the service selecting host  2 : Special 1; Special 2 (which is designated in the Transmission Subject column with “a male in his early 20s”); and Special 3 (which is designated in the Transmission Subject column with “KOBE city”. Each user is provided with a list of possible services in accordance with the information in their user data set. Further, an example of a list of channels provided from the service selecting host  2  to a user terminal  3  is depicted in FIG. 4 where a plurality of normal channels are listed along with special channels. When such a channel list is displayed on the screen of the user terminal  3 , it is possible to display the selection information as the channel name, or display the selection information by transmission subject.  
         [0118]    For the sake of simplicity, in the embodiment depicted in FIG. 4, the column of with the heading Channel Name indicates the service contents of various sorts of chats. In an actual case, the addresses used to access the respective services and the service names may be written.  
         [0119]    In accordance with the service correspondence table depicted in FIG. 3, a sports chat is transmitted to such a user terminal through which a user selects the SPECIAL-1 channel so as to receive the most popular service. Similarly, a weather forecast chat is transmitted to such a user terminal through which a user who is a male in his early twenties selects the SPECIAL-2 channel so as to receive the most popular service among the users with the same age. And in a case where the user is a single in thirties, the sports chat is transmitted. A similar service transmission is carried out when a user selects the SPECIAL-3 channel. It should be understood that when one of the Normal Channels is selected, she selected service is transmitted from the provider  4 , even though the selecting unit  10  did not select the channel for the service receiving apparatus  3 . Further, the host  2  still processes the selection of the Normal Channel by the service receiving apparatus  3 , updating the condition list  12  using the user data set transmitted from the service receiving apparatus  3 , and updating the service utilization list  7 , as is described in greater detail below.  
         [0120]    Process Flow in Service Providing System  
         [0121]    [0121]FIG. 5 schematically shows a process flow operation executed in the service providing system  2  according to the above-described embodiment.  
         [0122]    First, when a service is selected and entered via the user terminal  3  by a user, the service selection information is transmitted to the service selecting host  2  (#1). In this embodiment, for the sake of easy understanding, it is assumed that the SPECIAL-1 channel shown in FIG. 3 is selected. In this case, the service selection information transmitted to the service selecting host  2  includes information indicating that “the most popular of all selected services of user terminals has been selected”.  
         [0123]    The service selecting host  2  receives the transmitted selection information (#2), and reads the service correspondence table  7  from the storage unit (#3). The service selecting host  2  selects a service name corresponding to the selection information from the read service correspondence table  7  (#4). In this example, the sports chat corresponding to the SPECIAL-1 channel is selected as the service name.  
         [0124]    Subsequently, the service selecting host  2  reads an address of the sports chat from the address DB while using this service name as a key (#5), and then transmits the read address to the user terminal (#6).  
         [0125]    Upon receipt of the address of the selected service (#7), the user terminal  3  sends a request to the provider  4  (#8).  
         [0126]    The provider  4  which receives the request fetches a service stored at the received address (#10), and then transmits this fetched service to the user terminal  3  (#11).  
         [0127]    While receiving the service sent from the provider  4  (#12), the user terminal  3  sends a user data set every predetermined time “T 2 ” (#13) to the service selecting host  2  (#14) so as to update the condition list. The transmitted data is received (#15)  
         [0128]    Within a predetermined time “T 1 ” (#17), the service selecting host  2  receives a plurality of user data sets and stores these user data sets into a condition list  12  (#17). It should be noted that in order to store utilization information sent from as many user terminals as possible, the predetermined time “T 1 ” is made sufficiently longer than the time interval “T 2 ” during which the user terminal transmits the utilization information. When the user data sets are stored within the predetermined time T 1 , the service selecting host  2  compiles the utilization information, sorts, and updates the content of the service correspondence table  7  (#17).  
         [0129]    Operation of Service Selecting Host  
         [0130]    Referring now to a flow chart shown in FIG. 6, operation of the service selecting host  2  for executing the above-described process operations will be explained.  
         [0131]    First, at step S 41 , the following initialization is carried out, for instance, contents of a buffer used to read the service correspondence table and the addresses of the services are cleared.  
         [0132]    Second, at step S 42 , a determination is made as to whether or not the service selection information has been received from the user terminal  3 . If the service selection information is not received, the determination is repeated. When the service selection information is received, the process operation is advanced to step S 43 . That is, at step S 42 , the service selecting host  2  waits for the reception of the service selection information. As an example, it is now assumed that selection information corresponding to the SPECIAL-1 channel shown in the service correspondence table of FIG. 3 is received.  
         [0133]    At step S 43 , the service correspondence table  7  is read, and thereafter the process operation is advanced to step S 44 .  
         [0134]    At step S 44 , a service is identified that corresponds to the received selection information from the service correspondence table  7  to thereby acquire a name of this selected service. In this example, the sports chat is identified as the service name.  
         [0135]    At step S 45 , the address of the selected service, namely, the address of the sports chat in this case is read out from the address DB 9 , and then the process operation is advanced to step S 46 .  
         [0136]    At step S 46 , the read address is transmitted to the user terminal from which the selection information has been sent. Thereafter, the process operation is again returned to step S 41  at which the service selecting host  2  waits for the reception of the next selection information.  
         [0137]    Subsequent to step S 41 , while the process operations of step S 42  to step S 46 , process operations of step S 47  to step S 50  is carried out in a parallel manner.  
         [0138]    At step S 47 , a check is made as to whether or not the user data sets are received from a plurality of user terminals provided within the network. If the user data sets are received, then the process operation is advanced to step S 48 . Conversely, when the user data sets are not received, the process operation is again returned to step S 47 . That is, at step S 47 , the service selecting host  2  waits for the transmissions of the user data sets from the user terminal  3 .  
         [0139]    At step S 48 , the received user data sets are written into the condition list  12 , and then the process operation is advanced to step S 49 .  
         [0140]    At step S 49 , a check is made as to whether or not the predetermined time T 1  has passed. If the predetermined time T 1  has elapsed, then it is regarded that a sufficient amount of user data sets have been stored in the condition list  12 , and the process operation is advanced to step S 50 . Conversely, when the predetermined time T 1  has not yet passed, the process operation is returned to the previous step S 47  in order to further store the user data sets. At step S 47 , the service selecting host  2  waits for the reception of the user data set.  
         [0141]    At step S 50 , a sorting and updating sub-routine is carried out (as is described below) to rewrite the contents of the service correspondence table  7  by using the user data set stored in the condition list  12 . After the rewriting operation is completed, the process operation is returned to step S 47  at which the user data set is stored during the predetermined time T 1 .  
         [0142]    Operation of User Terminal  
         [0143]    Referring now to a flow chart shown in FIG. 7, operation of the user terminal  3  for executing the process operations indicated in FIG. 5 will be described.  
         [0144]    At step S 61 , the following initialization operation is carried out, for example, the contents of the buffer used to store the selection information, the address, and the user data set is cleared.  
         [0145]    At step S 62 , a check is made as to whether or not a channel is selected. When the channel is selected, the process operation is advanced to step S 63 . Conversely, when the channel is not selected, the process operation defined at step S 62  is repeated. Since just after the user terminal is connected to the network, the channel is not selected, it is so judged that the channel is not selected. It is now assumed that the SPECIAL-1 channel indicated in the service correspondence table shown in FIG. 3 is selected immediately after the user terminal is connected to the network.  
         [0146]    At step S 63 , a check is made as to whether or not a special channel is selected. If a special channel is selected, then the selection information is recorded and the process operation is advanced to step S 64 . Conversely if the special channel is not selected, since the normal channel is selected, then the process operation is advanced to step S 68  in order to request the provider  4  to provide the service.  
         [0147]    At step S 64 , another check is made as to whether or not the selection information is changed. When the selection information is changed, the process operation is advanced to step S 65  so as to select/receive a new service. Conversely, when the selection information has not changed, the process operation is advanced to step S 67 . In such a case that the channel is selected just after the user terminal is connected to the network, it is so judged that the selection information is changed, and then the process operation is advanced to step S 65 .  
         [0148]    At step S 65 , the selection information is transmitted to the service selecting host  2 . Since the SPECIAL-1 channel is selected, the above-explained selection information (1) “the most popular selected service of all subscribing user terminals” is transmitted as the selection information.  
         [0149]    At step S 66 , a determination is made as to whether or not an address is received from the service selecting host  2 . When the address is not received, the process operation is again returned to step S 65  at which the selection information is repeatedly transmitted. Conversely, when the address is received, the process operation is advanced to step S 67 .  
         [0150]    At step S 67 , a determination is made as to whether or not the address of the selected service is changed, namely whether or not the service corresponding to the selection information is changed. If the address has changed, then the process operation is advanced to step S 68  in order to receive another service. Conversely, when the address has not changed, since the selectively transmitted services are identical to each other, the process operation is advanced to step S 69 . It is determined that the address has changed just after the user terminal connected to the network, and then the process operation is advanced to step S 69 .  
         [0151]    At step S 68 , a request is sent to the provider  4  so as to request a service.  
         [0152]    At step S 69 , the reception of the service from the provider  4  is commenced. Since the service request operation and the service reception operation at step S 68  and step S 69  are similar to the sequential operation for receiving the normal IRC, a detailed description thereof is omitted.  
         [0153]    At step S 70 , a check is made as to whether or not the predetermined time “T 2 ” has passed after the service is started to be received. If the predetermined time T 2  has passed, then the process operation is advanced to step S 71 . Conversely, when the predetermined time T 2  has not yet passed, the process operation is again returned to step S 62 . At step S 62 , the determination as to whether or not the selection information is changed by a change in the channel is repeatedly performed.  
         [0154]    At step S 71 , the user data set is sent to the service selecting host  2 , and the process operation is again returned to step S 62 . At step S 62 , such a check is repeated to determine whether or not the selection information has been changed by entering new information in the service selection information.  
         [0155]    In other words, in such a case that the selection information (channel changing) is not changed by the user within the time T 2 , the process operation is advanced from step S 64  to step S 67 . For instance, when the SPECIAL-1 channel of FIG. 3 remains to be selected, a check is made at step S 67  as to whether or not the service of the SPECIAL-1 channel is changed into other chats than the sports chat. If the service of the SPECIAL-1 channel is changed, the replacing service is requested to the provider  4 . If not, then the sports chat is continuously received from the provider  4 .  
         [0156]    Conversely, even when there is a change in the selection information (namely, channel change) by the user within the time T 2 , if the services are identical to each other, it is so judged at step S 67  that there is no change in the address. Thus, the same service is continuously received from the provider.  
         [0157]    Sorting and Updating Sub-Routine  
         [0158]    In the flow chart shown in FIG. 6, when the service selecting host  2  stores the utilization information and the predetermined time T 1  has passed, the sorting and updating sub-routine of FIG. 8 is executed. For the sake of simple explanations, the following description is made of such a case that the service correspondence table  7  indicated in FIG. 3 is updated to produce another service correspondence table shown in FIG. 9.  
         [0159]    First, at step S 81  shown in FIG. 8, a determination is made as to whether or not a received user data set has previously been recorded in the condition list  12 . When it is determined that such a user data set is present, the process operation is advanced to step S 82 . Conversely, when it is determined that such a user data set is not present, the process operation is advanced to step S 84 .  
         [0160]    At step S 82 , one user data set is selected from the user data sets having the same receiving apparatus data, and then the process operation is advanced to step S 83 . There is no specific limitation on how to select one user data set. For example, the latest user data set may be selected.  
         [0161]    At step S 83 , the user data sets having the same receiving apparatus data except for those selected at the former step are deleted from the condition list  12 , and the process operation is advanced to step S 84 .  
         [0162]    At step S 84 , one set of criteria of selection information among all of the preset selection information is set to be updated. In this embodiment, one of the below-mentioned three sets of criteria or combinations of selection information are used as examples of such selection information which are to be updated (the selection information is sorted in order to update the list of services in the list  7 ):  
         [0163]    (1) The most popular selected services in all of the subscribing user terminals.  
         [0164]    (2) The most appropriate and popular of all selected services accessed by subscribing user terminals where the most appropriate criteria is based upon a commonality between classification of user&#39;s attribute data and selected service data in the user terminals from subscribing user terminals;  
         [0165]    (3) The most appropriate selected services in the user terminals where the most appropriate criteria is based upon a commonality between the user&#39;s utilization place data and selected service data in subscribing user terminals.  
         [0166]    As to each of the above sets of selection information (1) to (3) above, process operations at steps subsequent to step S 85  are repeatedly performed until all three sets of selection information are processed and updated data is produced. In other words, steps S 84  through steps S 88  repeat once for each set of selection information (1) to (3).  
         [0167]    In the case that selection information (1) is set in step S 84 , user data set which has commonality with the selection information is selected. First of all, the user data sets having the same selection service data are grouped, a maximum group is searched in which the total number of user data sets within that group becomes a maximum, and then, one of these user data sets is recognized as a representative user data set. When there are plural maximum groups, any one of these maximum groups may be selected. Also, the representative user data set may be arbitrarily selected from the maximum group. It is now assumed that the selected service of the representative user data set is the NORMAL-1 channel of the normal IRC channel.  
         [0168]    Next, at step S 86 , a service name provided in the same channel as the selected service of the representative user data set is specified with reference to the service correspondence table  7  shown in FIG. 3. In this embodiment, the service name “current event chat” provided in the NORMAL-1 channel is specified.  
         [0169]    At step S 87 , a special channel is specified which corresponds to the selection information from the SPECIAL-1 channel to the SPECIAL-3 channel with reference again to the service correspondence table  7  shown in FIG. 3. In the case of FIG. 3, the special channel in which the user terminals connect to the most is the SPECIAL-1 channel. When the special channel is specified, the service name of the specified special channel is rewritten to the service name of the representative user data set. In this embodiment, the service name “sports chat” of the SPECIAL-1 channel indicated in FIG. 3 is rewritten or updated to the service name “current event chat” shown in FIG. 9.  
         [0170]    At step S 88 , a check is made as to whether or not the services are have been searched and sorted as to all of the totalization conditions (1) to (3). If the services are not yet searched and sorted, then the process operation is returned to step S 84 . At step S 84 , the next totalization condition is determined. If the services are searched and sorted with respect to all of the totalization conditions, then it is regarded that the updating operation of the service correspondence table  7  is accomplished, and thus the process operation is returned to the main routine shown in FIG. 6.  
         [0171]    When the selection information (2) is set at step S 85 , the user data sets having the same selected service data and the same user attributes are respectively grouped, a representative user data set is determined in a similar manner to the above-described. Similar to the above description, when there are plural maximum groups, any one of these maximum groups may be selected. Also, the representative user data set may be arbitrarily selected from the maximum groups.  
         [0172]    Now, considering the case, when a plurality of classifications are set as the user attribute data, a representative user data set is selected from each of these classifications. In this embodiment, a representative user data set is selected from each of the two classifications of the user attribute data, i.e., “a male in his early twenties”, and “a single in the thirties”. It is now assumed that as one example, the selected service of the representative user data set corresponds to the NORMAL-5 channel of the normal IRC channel, and the user attribute data corresponds to “a male in his early twenties”.  
         [0173]    Next, at step S 86 , a service name provided in the selected channel of the representative user data set is specified with reference to the service correspondence table  7  in a similar manner to the above explanation. In this case, the service name “movies chat” is provided in the NORMAL-5 channel.  
         [0174]    At step S 87  similar to the above explanation, with reference again to the service correspondence table  7 , a special channel is selected based upon the criteria contained in the representative user data. The service name of this specific channel is rewritten to the specified service name.
