         [0038]     Note that the present invention is not to be limited to the above embodiments and able to be embodied in various forms without departing from the scope thereof.  
       First Embodiment  
       [0039]      FIG. 1  is a schematic diagram explaining the first embodiment. Hereinbelow, the first embodiment will be described with reference to  FIG. 1 .  
         [0040]     The portal system of the present invention comprises the portal screen display apparatus ( 0101  to  0103 ), and the portal screen server apparatus ( 0104 ). As shown in  FIG. 1 , multiple portal screen display apparatus are used. Although a single portal screen server apparatus is shown in  FIG. 1 , multiple portal screen server apparatus may be used. In  FIG. 1 , the portal screen display apparatus is a digital television with internet function placed in each user&#39;s home.  
         [0041]     The present system is characterized in that the portal screen display apparatus stores the identification information of apparatus unique to respective apparatuses, and when the request signal for portal screen display is transmitted from the apparatus to portal screen server apparatus, the identification information of apparatus is correlated with the request signal for portal screen display. The identification information of apparatus is information for identifying the apparatus itself such as a production number. The information is transmitted to the portal screen display server apparatus, so that the portal screen display apparatus can identify which portal screen display apparatus transmitted the request signal for portal screen display.  
         [0042]     For example, the portal careen display apparatus  1  ( 0101 ) stores the identification information of apparatus such as ‘AX1234561000005’, in which ‘A’ which is a code indicating that the apparatus was manufactured by A, ‘X’, which is a code indicating the type of apparatus, ‘123456’, which is the production number or the apparatus, and ‘1000005’, which is the postal code of the place in which the apparatus is located (Marunouchi, Chiyoda-ku, Tokyo), are combined. The portal screen display server apparatus ( 0104 ), which has received a request for weather forecast for one day in the area (Marunouchi, Chiyoda-ku, Tokyo), in which the apparatus is located, as the portal screen display information from the apparatus, after collating the request signal with a list of the identification information of the apparatus, which is stored by the apparatus, and confirming that request signal has definitely been transmitted from the apparatus, transmits the portal screen display information, which includes the weather forecast for one day in the area, to the portal screen display apparatus  1  ( 0101 ). Thus, it becomes possible for a user to see the weather forecast on the portal screen of the digital television with internet function in the user&#39;s home.  
         [0043]     Further, for example, the portal screen display apparatus  2  ( 0102 ) stores the identification information of apparatus such as ‘BY13579’, in which ‘B’ which is a code indicating that the apparatus was manufactured by B, ‘Y’, which is a code indicating the type of apparatus, and ‘3579’, which is the production number or the apparatus, are combined. The portal screen display server apparatus ( 0104 ), which has received a request for an information search screen in the internet as the portal screen display information from the apparatus, after collating the request signal with a list of the identification information of the apparatus, which is stored by the apparatus, and confirming that request signal has definitely been transmitted from the apparatus, transmits the portal screen display information, which includes the information search screen, to the portal screen display apparatus  2  ( 0102 ). Thus, it becomes possible for a user to search using the information search screen on the portal screen of the digital television with internet function in the user&#39;s home.  
         [0044]     Furthermore, for example, the portal screen display apparatus  3  ( 0103 ) stores the identification information of apparatus such as ‘AX234567C06’, in which ‘A’ which is the code indicating that tee apparatus was manufactured by A, ‘X’, which is a code indicating the type of apparatus, ‘234567’, which is the production number or the apparatus, and ‘C’, which is the code indicating a local station in Osaka of C broadcasting station, the CATV station, to which the user of the apparatus subscribes, are combined. The portal screen display server apparatus ( 0104 ), which has received a request for a news program as the portal screen display information from the apparatus, after collating the request signal with a list of the identification information of apparatus, which is stored by the apparatus, and confirming that request signal has definitely been transmitted from the apparatus, transmits the portal screen display information, which includes the news program for Osaka area provided by C broadcasting station, to the portal screen display apparatus  3  ( 0103 ). Thus, it becomes possible for a user to watch the news program on the portal screen of the digital television with internet function in the user&#39;s home.  
         [0045]      FIG. 2  is a functional block diagram explaining the first embodiment.  
         [0046]     The respective units, the constituents of the present invention, consisting of any one of hardware, software, or both hardware and software. For example, in cases where a computer is used, hardware consisting of CPU, memory, bus, interface, peripheral devices etc., and software, operatable on the hardware, are used for implementing them.  
         [0047]     Specifically, by sequentially carrying out programs on the memory, the data on the memory, or the data inputted via the interface is processed, stored and outputted, so that the functions of respective units are implemented.  
         [0048]     The ‘portal system’ ( 0200 ) of the first embodiment comprises the ‘portal screen display apparatus’ ( 0210 ), and the ‘portal screen server apparatus’ ( 0220 ).  
         [0049]     The ‘portal screen display apparatus’ ( 0210 ) comprises the ‘storage for identification information of apparatus’ ( 0211 ), the ‘generator for request signal for portal screen display information’ ( 0212 ), the ‘transmit for request signal for portal screen display information’ ( 0213 ), the ‘receiver for portal screen display information’ ( 0214 ), and the ‘display’ ( 0215 ).  
         [0050]     The ‘portal screen’ is, generally speaking, an initial screen displayed upon switching on the portal screen display apparatus, but is not limited to this. For example, in an apparatus having both functions of broadcasting receiving function and internet connecting function, if the initial screen is the broadcasting receiving screen, the screen initially displayed upon changing to the internet connecting function may be the initial screen as well.  
         [0051]     The portal screen makes a strong impression of a screen displayed on an electronic apparatus to a user. For example, the manufacturer of the apparatus can increase the manufacturer&#39;s name awareness to user by displaying the manufacturer&#39;s name on the portal screen, thereby improving the manufacturer&#39;s image if the apparatus is good. The reason for this is that the user always sees the portal screen at the outset of using the electronic apparatus, and therefore, the portal screen has a different value from the other screen displayable on the electronic apparatus.  
         [0052]     The ‘portal screen display apparatus’ ( 0210 ) is a apparatus such as a personal computer, a mobile phone, a television, and the other home appliances, for displaying a screen provided from the portal screen server apparatus so that a user can see it.  
         [0053]     The ‘storage for identification information of apparatus’ ( 0211 ) stores identification information of apparatus including identification information of manufacturer, which identifies its own manufacturer, in a non-rewritable state. The ‘identification information of manufacturer’ is information for uniquely identifying a manufacturer. In this case, the manufacturer may include a manufacturer of an entire apparatus, or a manufacturer of a component of the apparatus, for example, only a component constituting information-communication function. Further, examples of the identification information of manufacturer include the production number of the apparatus, model code of the apparatus, or original ID assigned for identifying the apparatus.  
         [0054]     In addition, the identification information of manufacturer is stored in a non-rewritable state. Specifically, this information is information stored in a ROM, so that user etc. of an electronic apparatus cannot rewrite the content of this information. Therefore, the term ‘non-rewritable’ means that once the identification information of manufacturer is generated and stored, essentially, nobody can change the information content. The reason for this is to secure the function of preventing masquerading by a third party, by correlating the information indicating which user send the portal screen display information with the identification information of manufacturer. However, without contradicting the above purpose, rewriting may be allowed in certain cases. Examples of the certain cases include, the case where it becomes necessary to renew the identification information of manufacturer because of division of the manufacturer of the apparatus, the case where it becomes necessary to renew the model code of the apparatus in order to indicate that the apparatus has the additional function if a part of the function has been added to the apparatus, and the case where it becomes necessary to repair the apparatus. In such cases, the rewriting is carried out on the basis of the information etc., which is known only by the manufacturer of the apparatus, in order to prevent masquerading by a third party caused by leak of the identification information of apparatus.  
         [0055]     The ‘generator for request signal for portal screen display information’ ( 0212 ) generates a request signal for portal screen display information, which is a signal for requesting the portal screen display information to said portal screen server apparatus.  
         [0056]     The ‘request signal for portal screen display information’ is a signal, which indicates information as to which screen is desired to be displayed, and requests for the display of the screen.  
         [0057]     The ‘transmitter for request signal for portal screen display information’ ( 0213 ) transmits the request signal for portal screen display information, and said identification information of apparatus correlated with said request signal for portal screen display information. In this ease, URL, which is the destination of a reply of the portal screen display information from the portal screen display server apparatus, may be transmitted at that point. Further, the transmission may be carried out via any of telephone line, internet connection, or a combination thereof.  
         [0058]     The ‘receiver for portal screen display information’ ( 0214 ) receives the portal screen display information from said portal screen server apparatus. The reception may be carried out via any of telephone line, internet connection, or a combination thereof. Further the ‘portal screen display information’ is information transmitted from the portal screen display apparatus as the information displayed on the portal screen. Here, there are two cases the case where all information to be displayed are transmitted from the portal server, and the case where the information to be displayed is preliminarily stored in the portal screen display apparatus, and the portal screen display apparatus displays the required information based on the instruction transmitted from the portal screen server apparatus.  
         [0059]     The ‘display’ ( 0215 ) displays a portal screen based on the portal screen display information received by said receiver for portal screen display information. The display of the portal screen may occupy the entire displayable portion of the apparatus, or a portion thereof. In the latter case, for example, the display of the portal screen and the reception screen of television broadcasting occupy half of the displayable portion, respectively.  
         [0060]     In addition, the ‘portal screen server apparatus’ comprises the ‘receiver for request signal for portal screen display information’ ( 0221 ), the ‘storage for portal screen display information’ ( 0222 ), the ‘first determination unit’ ( 0223 ), and the ‘transmitter for portal screen display information’ ( 0224 ). This apparatus may be single, or may be multiple.  
         [0061]     The ‘receiver for request signal for portal screen display information’ ( 0221 ) receives the request signal for portal screen display information. The reception may be carried out via any of telephone line, internet connection, or a combination thereof.  
         [0062]     The ‘storage for portal screen display information’ ( 0222 ) stores the portal screen display information corresponding to said identification information of apparatus. In this case, the term ‘correspondence’ may be a one-on-one correspondence between the entire identification information of apparatus and the portal screen display information, or a one-on-one correspondence between one portion of the identification information of apparatus and the portal screen display information. The latter is, for example, a one-on-one correspondence between the initial three digits of the identification information of apparatus and the portal screen display information. In this case, the same portal screen display information is transmitted to multiple portal screen display apparatus, which commonly share the initial three digits.  
         [0063]     The ‘first determination unit’ ( 0223 ) determines whether said identification information of apparatus is correlated with the request signal for portal screen display information received by said receiver for request signal for portal screen display information. The case where the identification information of apparatus is not correlated with. The request signal for portal screen display information includes the case where the request signal is incorrect, but does not include the information to be essentially included in the identification information of apparatus, and the contrary case where the information other than the identification information of apparatus is included. In the latter case, a process for collating the list of the identification information of apparatus, which is preliminarily stored in the portal screen server apparatus, with the information transmitted as the identification information of apparatus is included in the determination process carried out by the first determination unit. Note that, the collating method may include the method for checking whether the information identical to the information transmitted as the identification information of apparatus is included in the list, and the method for checking whether a predetermined effect is acquired by carrying out a certain process on the information transmitted as the identification information of apparatus. For example, in the latter case, the setting, in which the final digit of the sum of the digit portion in the correct identification information of apparatus preliminarily stored is always ‘0’, is done, and whether the information transmitted as the identification information of apparatus fulfills this condition is checked.  
         [0064]     The ‘transmitter for portal screen display information’ ( 0224 ) acquires said portal screen display information corresponding to the identification information of apparatus from said storage for portal screen display information, and transmits it to said portal screen display apparatus, if the determination result by said first determination unit indicates that said identification information of apparatus is correlated with the request signal. The transmission may be carried out via any of telephone line, internet connection, or a combination thereof.  
         [0065]     Note that it is preferable that the address of transmission destination is preliminarily stored as the address correlated with the identification information of apparatus. In this case, the ‘transmitter for portal screen display information’ ( 0224 ) stores the address information, which is preliminarily registered.  
         [0066]      FIG. 3  is a functional block diagram explaining the function of the identification information of apparatus in the system configuration of the first embodiment.  
         [0067]     In  FIG. 3 , the identification information of apparatus is preliminarily stored in the ‘storage for identification information of apparatus’ ( 0311 ) of the ‘portal screen display apparatus’ ( 0310 ).  
         [0068]     As to the identification information of apparatus, when the ‘transmitter for request signal for portal screen display information’ ( 0313 ) of the apparatus ( 0310 ) transmits the request signal for portal screen display information, the identification information is correlated with the signal, and is transmitted ( 0332 ).  
         [0069]     The transmitted identification information of apparatus is received ( 0334 ) by the ‘receiver for request signal for portal screen display information’ ( 0321 ) of the ‘portal screen server apparatus’ ( 0321 ).  
         [0070]     It is determined ( 0335 ) whether the received identification information of apparatus has been correlated with the request signal for portal screen display information by the ‘first determination unit’ ( 0323 ) of the apparatus ( 0320 ). At that point, the determination is carried out, in the example of  FIG. 3 , based on the collation list of identification information of apparatus ( 0336 ), which is preliminarily stored in the unit ( 0323 ).  
         [0071]     As a result of the determination, if it is determined that the identification information of apparatus is correlated with the request signal, the ‘transmitter for portal screen display information’ ( 0324 ) of the apparatus ( 0320 ) transmits ( 0337 ) the portal screen display information corresponding to the identification information of apparatus to the ‘receiver for portal screen display information’ of the ‘portal screen display apparatus’ ( 0310 ). At that point, the address of the unit ( 0314 ), which is a transmission destination, is, in the example of  FIG. 3 , based on the address information ( 0338 ) correlated with the preliminarily stored identification information of apparatus.  
         [0072]     The transmitted portal screen display information is received at the address ( 0333 ) of the ‘receiver for portal screen display information’ ( 0314 ), and the information is displayed by the ‘display’ ( 0315 ) of the ‘portal screen display apparatus’ ( 0310 ).  
         [0073]      FIG. 4  is a schematic diagram exemplifying the state where the portal screen is displayed on the portal screen display apparatus.  
         [0074]     In  FIG. 4 , the portal screen including ‘Weather in Choyoda-ku, Tokyo’ is displayed. Therefore, the information as to the weather and temperature etc. for today and tomorrow in Chiyoda-ku is displayed in the middle of the screen and the information as to the weekly weather in Chiyoda-ku is displayed in the lower portion of the screen. In addition, for example, in the same screen, it is possible to change the sheet of ‘Chiyoda-ka’ to the sheet displaying the weather of other area such as ‘Kanto’ or ‘Japan’. Further, clicking on the upper-loft icon, it is possible to store, print, or zoom-in on the portal screen. Furthermore, it is possible to change it to the screen such as the list of other menus or television screen other than the portal screen.  
         [0075]      FIG. 5  is a functional block diagram explaining the function of the identification information of apparatus in the system configuration of the first embodiment according to the concrete example.  
         [0076]      FIG. 5  shows the case of the identification information of manufacturer included in the identification information of apparatus, and in  FIG. 5 , A is the manufacturer.  
         [0077]     In  FIG. 5 , the identification information of apparatus including the identification information of manufacturer of A is preliminarily stored in the ‘storage for portal screen display information’ ( 0511 ) of the ‘the portal screen display apparatus’ ( 0510 ). In  FIG. 5 , the identification information of manufacturer is indicated by ‘A’, and the identification information of apparatus, including ‘A’, is indicated by ‘AX123456’ ( 0531 ).  
         [0078]     As to the identification information of apparatus, when the ‘transmitter for request signal for portal screen display information’ ( 0513 ) of the apparatus ( 0510 ) transmits the request signal for portal screen display information, the ‘AX123456’ is correlated with the signal, and is transmitted ( 0532 ), so that the identification information of apparatus ‘A’ of the manufacturer A is included therein and transmitted.  
         [0079]     The transmitted identification information of apparatus ‘AX123456’, including ‘A’, is received ( 0534 ) by the ‘receiver for request signal for portal screen display information’ ( 0521 ) of the ‘portal screen server apparatus’ ( 0520 ).  
         [0080]     It is determined ( 0535 ) whether the received identification information of apparatus has been correlated with the request signal for portal screen display information by the ‘first determination unit’ ( 0523 ) of the apparatus ( 0520 ). At that point, the determination is carried out, in the example of  FIG. 5 , based on the collation list of identification information of apparatus ( 0536 ), which is preliminarily stored in the unit ( 0523 ), by collating, for example, whether the ‘AX123456’ exists in the list. As a result of this determination, the apparatus ( 0520 ) can know whether the received request signal for portal screen display information has been transmitted from the portal screen display apparatus, which has been manufactured by A. Consequently, the portal screen server apparatus can display the appropriate portal screen for the apparatus manufactured by A  
         [0081]     As a result of the determination, if it is determined that the identification information of apparatus including the identification information of manufacturer is correlated with the request signal for portal screen display information, the ‘transmitter for portal screen display information’ ( 0524 ) of the apparatus ( 0520 ) transmits ( 0537 ) the portal screen display information corresponding to the identification information of apparatus including the identification information of manufacturer (in  FIG. 5 , product information of A) to the ‘receiver for portal screen display information’ ( 0514 ) of the ‘portal screen display apparatus’ ( 0510 ).  
         [0082]     The portal screen display information corresponding to the identification information of apparatus including the identification information of manufacturer is, for example, in cases where the portal screen display apparatus is manufactured by A, the product information of A is displayed on the portable screen. Alternatively, ‘Q &amp; A’ as to an instruction manual of the product manufactured by A may be displayed. Alternatively, a button to connect to the technical center of A for request of repair or inspection etc. may be displayed. Alternatively, a button for downloading an upgraded version of the software of the product manufactured by A may be displayed. Alternatively, an icon for operating a function specific to the product manufactured by A may be displayed. For example, as the case where an operation button of an air conditioner is displayed and by pressing the button, the air conditioner can be operated, the button for communicating with the other home appliances in a home is displayed.  
         [0083]     At that point, the address ( 0533 ) of the unit ( 0514 ), which is a transmission destination, is, in the example of  FIG. 5 , based on the address information ( 0538 ) correlated with the preliminarily stored identification information of apparatus.
