[0107] The usage form information UFI_1 and UFI_2 are for example files and other modules.

[0108] The usage form information UFI_1 and UFI_2 are stored in the database in the storage 52 in the form of a DOM structure of the XML. The database is updated when new usage form information UFI_1 is received or when new internal state information ISI is received.

[0109] The processor 53 is realized by using the CPU 204 shown in FIG. 6 and the processor 53 is, as shown in FIG. 6, comprises a home network apparatus control function 60, a received content processing function 61, and a STB specific processing function 62.

[0110] The home network apparatus control function 60, as shown in FIG. 7, inputs and outputs necessary information with the STB specific processing function 62 to produce the notification NTF and transmits the same to the electrical apparatuses 11_1, 11_2, and 11_3 via the home network 10.

[0111] The received content processing function 61, as shown in FIG. 7, converts the content information received from the content provider apparatus 2 to match the current internal state of the home network system 8 using the usage form information UFI_1 received from the server apparatus 4 and the internal state information ISI received from the server apparatus 20 and electrical apparatuses 11_1, 11_2, and 11_3.

[0112] The STB specific processing function 62 performs processing specific as a set top box.

[0113] Below, an example of the operation of the communication system 1 will be explained.

[0114] FIG. 8 and FIG. 9 are flow charts for explaining an example of the operation of the communication system 1.

[0115] Step ST1:

[0116] For example, when the advertisement content information is broadcasted from the broadcasting station 3, usage form information UF_1 defining a usage form of content information of an advertisement for each of a plurality of internal state of the home network system 8 of the content user side is produced by the extensible stylesheet transformation (XSLT) format at the server apparatus 4.

[0117] The usage form information UFI_1 indicates a routine for transforming the content information received by the set top box 15 from the content provider apparatus 2 into a form actually used and comprises a plurality of elements arranged in a tree structure.

[0118] For example, as one example, the usage form information UFI_1 indicates to display an advertisement of a car A when the increase of the amount of a user's bank account is equal to or greater than 9 million yen and the increase rate is equal to or greater than 50%, display an advertisement of a car B when the balance of the user's bank account is equal to or greater than 10 million yen, and display the advertisement of a car C when the balance of the user's bank account is less than 10 million yen.

[0119] Step ST2:

[0120] The usage form information UFI_1 produced at step ST1 is transmitted from the content provider apparatus 4 and received by the internal interface 51 of the set top box 15 shown in FIG. 6. via the Internet 6, computer 12 and the network 10.

[0121] Step ST3:

[0122] The usage form information UFI_1 received at step ST2 is analyzed according to a document object model (DOM) by the received content processing function 61 of the set top box 15 shown in FIG. 6 and the necessary information is extracted. That is, parse processing is performed.

[0123] Step ST4:

[0124] The usage form information UFI_1 parse processed by the received content processing function 61 is added to the database of the usage form information UFI_1 in the storage 52.

[0125] Step ST5:

[0126] The network bank terminal 13 communicates with the server apparatus 20 and receives the information indicating that, for example, the funds of the user 7 in the bank account has increased by 9.5 million yen due to winning the lottery and the balance has become 17.3 million yen.

[0127] Step ST6:

[0128] The network bank terminal 13 produces the internal state information ISI indicating an amount of increase of funds, a rate of increase, and a balance indicated by the bank account of the user 7 in the XML format by using the information obtained in the step ST5.

[0129] Step ST7:

[0130] The internal state information ISI produced in the step ST6 is transmitted from the network bank terminal 13 to the STB 15 via the home network 10.

[0131] The internal state information ISI is received by the internal interface 51 of the set top box 15 shown in FIG. 6.

[0132] Step ST8:

[0133] The usage form information UFI_2 matching the internal state of the user 7 is produced by using the usage form information UFI_1 stored in the storage 52 at step ST4 and the internal state information ISI received at step ST7 by the received content processing function 61 of the processor 53 of the set top box 15 shown in FIG. 6.

[0134] Step ST9:

[0135] The usage form information UFI_2 produced at step ST8 is added to the database of the usage form information UFI_2 in the storage 52.

[0136] Step ST10:

[0137] The content provider apparatus 2 produces the content information of the program and the advertisement in the XML format, and the content information is broadcast by a wireless system or wired system.

[0138] The content information is received by the external interface 50 of the set top box 15 shown in FIG. 6.

[0139] The content information is for example content information of the advertisement of the car A, car B, and car C.

[0140] Step ST11:

[0141] The content information received at step ST9 is converted into content information for output using the usage form information UFI_2 produced at step ST8 by the received content processing function 61 of the processor 53 of the set top box 15 shown in FIG. 6. The output content information is described in the XML format.

[0142] At this time, the condition (a) of step ST1 is satisfied, therefore the advertisement of the car A is selected as an advertisement in the output content information. Therefore, the television receiver 14 outputs the video and audio of the program and video and audio of the advertisement of the car A.

[0143] Below, an explanation will be made of the information described by the XSLT format and XML format used by the processing shown in FIG. 8 and FIG. 9 by using the above advertisement of the car described above as an example.
