A set of content IDs to be described later is arranged by the number of rows × the number of columns. Is done. In the update information, the date and time (up-dated date) at which the display format data was distributed is arranged.

According to the above display format data, for example, when the number of rows or the number of columns is I or J, respectively, as shown in FIG. A frame composed of columns (areas) is displayed. Then, assuming that certain EPG data is represented as EPG data (i, j) and the content ID of the EPG data is represented as content ID (i, j), the area data (i, j) I), j that specifies
And the content ID (i, j) are set, as shown in FIG. 5, the i-th row and the j-th column of the frame composed of J × I columns EPG data (i, j) is displayed in the column.

FIG. 6 shows the format of the content data.

The content data is, as shown in FIG.

e) are arranged sequentially.

In the number of information, the number of information that follows is arranged. The information includes specific information identified by the tag, that is, specific subtitles, names of performers, and the like.

Use placed after div_num as described above
In r_add (FIG. 6A), terminal data indicating that a recording reservation is made for a program is arranged. That is, when an instruction to make a recording reservation for a certain program is stored in the HD 14 as terminal data, the data configuration unit 18 stores the recording reservation for the program in user_add of the content data in which the EPG data of the program is arranged. It is arranged that it is done. User_add is an integer type (int type)
Or it is a character type (char type).

In the priority ID, information (hereinafter, referred to as priority information as appropriate) indicating the priority of the recording reservation or the like is arranged in an integer type (int type). That is, the terminal data transmitted from the mobile terminal 8 _n includes:
Priority information can be attached,
For example, an instruction to make a recording reservation for a certain program is stored in the HD 14 as terminal data, and the user_add of the content data in which the EPG data of the program is placed is set to indicate that the recording of the program is reserved. In this case, when the priority information is added to the terminal data, the priority information is assigned to the priority ID. In the case where an instruction to make a recording reservation as terminal data to which priority information with a higher priority is added is already stored in the HD 14, the terminal data to which priority information with a lower priority is added as the terminal data. When the instruction to make the recording reservation is transmitted, the recording reservation with the lower priority is rejected. Thus, during each portable terminal 8 ₁ to 8 _N, it is made so to speak to be able to give the relative merits. Here, the priority information can be set in advance in, for example, each of the mobile terminals 8 _{1 to} 8 _N, or can be input by the user after the power of the mobile terminal 8 _n is turned on, for example. It is also possible.

According to the display format data and the content data as described above, for example, the following EPG can be displayed.

That is, for example, it is assumed that the display format data as shown in FIG. 7A is selected by the selection unit 32 of the portable terminal 8 _n . Here, in FIG. 7A, the number of rows or the number of columns is I or J, respectively. Also,
The area data is configured such that the content ID of the content data displayed in the area (i, j) is #ij.

In this case, the selection section 32 of the portable terminal 8 _n has the following content data to be displayed in the area (i, j):
A content ID of #ij is selected.

Therefore, assuming that the content data having the content ID #ij, for example, as shown in FIG. 7 (B) is configured and distributed in the STB 7, the selection unit of the portable terminal 8 _n At 32, this content data is selected. Here, in the content data of FIG. 7B, the characters “TITLE” are arranged in the title. In addition, no data is arranged in div_num and user_add (NULL).

In this case, in the display unit 34 of the portable terminal 8 _n , a rectangular i-th row and j-th column as shown in FIG.
The content data whose content ID is #ij is displayed. Then, as shown in FIG. 8A, in the column of the i-th row and the j-th column,
An EPG in which the characters “TITLE” arranged in the content data of FIG. 7B are displayed. Therefore, in this case, the user can receive the EPG displaying only the title of the program.

Depending on how the area data in the display format data is structured, that is, how to determine the content ID of the content data to be displayed in the column of the i-th row and the j-th column, for example, a channel or a channel in the horizontal direction or the vertical direction may be used. It is possible to display an EPG as a time, an EPG as a day of the week or a channel in the horizontal or vertical direction, or the like.

Next, as content data having a content ID of #ij, for example, the content data shown in FIG.
Assuming that the content is configured and distributed in the TB 7, the selection unit 32 of the mobile terminal 8 _n selects the content data. Here, in FIG. 7C, the title and
No data is allocated to user_add. Also, div_
In num, the TLV number is 1, and therefore,
One TLV is arranged. And this 1 TLV
In, the tag is that of "performer" and the number of information is 2. Therefore, the names of the two performers are arranged, and in the embodiment of FIG. 7C, the names of the two performers are “XXO husband” and “XXX child”. Has become.

In this case, on the display unit 34 of the portable terminal 8 _n , a rectangular i-th row and j-th column as shown in FIG.
After the content data with the content ID #ij is displayed,
As shown in FIG. 8B, the column of the i-th row and the j-th column contains FIG.
"XX husband" and "XX" arranged in the content data of (C)
The EPG in which the characters “× child” are arranged is displayed. Therefore, in this case, the user can receive the EPG displaying only the names of the performers of the program.

As the content data having the content ID #ij, for example, the content data shown in FIG.
Assuming that the content is configured and distributed in the TB 7, the selection unit 32 of the mobile terminal 8 _n selects the content data. Here, in FIG. 7D, the title includes:
The character “TITLE” is arranged, and no data is arranged in div_num. Also, user_add contains
The text "Reserved by @" indicating that someone in the family has made a recording reservation is placed. Here, the name and the like of the family who has made a recording reservation are placed in △△.

Then, on the display unit 34 of the portable terminal 8 _n ,
After the content data with the content ID #ij is displayed in the column of the i-th row and the j-th column of the rectangle as shown in FIG.
As shown in FIG. 7 (C), the column of the i-th row and the j-th column contains FIG.
The EPG in which the characters "TITLE" and "reserved" arranged in the content data of "E." Therefore,
In this case, the user displays only the program title E
In addition to being able to receive PG offers, for each program,
It is also possible to recognize whether or not a recording reservation has been made.

Here, one of the family members has their own mobile terminal 8.
_{When n} is operated to make a recording reservation for a certain program, terminal data for instructing the recording reservation is transmitted to the STB 7,
In the control unit 20 of the TB 7, a recording reservation of a VTR, which is one of the electronic devices 9, is made. Furthermore, in STB7,
The terminal data for instructing the recording reservation is stored in the HD 14,
By referring to the storage content of the HD 14 in the data configuration unit 18, when configuring the content data of the program for which recording reservation has been instructed, the character “Reserved” indicating that the recording of the program has been reserved is displayed. Located in user_add. In this way, the content data as shown in FIG.

As described above, the EPG is displayed on the portable terminal 8 _n owned by each family member.
You can see the EPG without disturbing other family members. Further, the STB 7 is set so that each family member forms the display format data of the display format desired by himself / herself, and the portable terminal 8 _n (selection unit 32) sets the display format data that suits his / her preference. By selecting the display format data, the EPG in such a form can be viewed. Further, the user who wants to confirm whether or not there is a recording reservation is arranged so that the presence or absence of the recording reservation is arranged in the content data.
By setting TB7, it is possible to check whether or not there is a recording reservation of a program at the same time as watching the EPG.

In the portable terminal 8 _n , only the data necessary for the user is extracted (selected) from the display format data and the content data configured using the EPG data extracted from the program arrangement information. The load required for the extraction is smaller than in the case where only the information necessary for the user is extracted from the program arrangement information having a much larger data amount than the data. Further, in the present embodiment, STB7
Since the wireless communication is performed between the mobile terminal 8 _n and the mobile terminal 8 _n , the STB 7 repeatedly delivers the same data a certain number of times in order to prevent data loss in the mobile terminal 8 _n. However, when such repeated distribution is performed, by distributing not the program arrangement information itself but EPG data extracted therefrom, it is possible to increase the number of times of repeated data distribution in a certain unit time. Therefore, when certain data is repeatedly delivered a predetermined number of times, the types of data to be delivered in a certain unit time can be increased, and as a result, the portable terminal 8 _n transmits the data it needs to itself.
Reception can be performed relatively quickly.

Further, in the present embodiment, wireless communication is performed between the STB 7 and the portable terminal 8 _n , but wired communication may be performed between them. . However, when wireless communication is performed between the STB 7 and the mobile terminal 8 _n , the number of the mobile terminals 8 _n is not limited, and the EPG can be acquired anywhere in the home. Becomes In the case of wireless communication, for example, a communication method between the master unit and the slave unit of the master-slave telephone set can be used. Furthermore, when using the communication method of the parent and child telephones, the communication is performed with low power that does not require a wireless license according to the law, so that the power consumption can be reduced.

As a format for performing data communication between the STB 7 and the portable terminal 8 _n , for example, a TS packet (transport stream packet) can be used. In this case, the system development cost Can be reduced.

Further, data can be distributed from the STB 7 to the portable terminal 8 _n by using the format of the program arrangement information specified by ARIB.
When using the format of the program arrangement information, it is necessary to add a tag (table_id) for identifying each information, but the data (EP) included in the program arrangement information is required.
G data), the tag originally attached to the G data may be used. For other items, for example, user_add, 0x90 which can be arbitrarily set by the business operator
A value in the range of 0 to 0xBF may be used (0x indicates that the subsequent value is a hexadecimal number).

Further, in the present embodiment, user_add
The information that the recording reservation was made by somebody is placed in the user_add, but in addition to the information that the recording reservation was made by someone, for example, since the father made the recording reservation by his father, It is also possible to arrange a comment or the like that cannot be canceled. Also, user
In addition, for example, information such as whether the program has been viewed in the past, the degree of interest in the program based on the number of times the program has been viewed, and the like can be placed in _add.

Further, in this embodiment, the information on the program is exchanged between the STB 7 and the portable terminal 8 _n . However, other information in the home, that is, for example, notes of our home (for example, , Smoking cessation, etc.), dinner time and menu, and the fact that he is on a business trip. That is, for example, the mother operates his / her own mobile terminal 8 _n to indicate that smoking is quit.
The data is transmitted to the STB 7 as terminal data. In this case, S
In TB7, terminal data indicating that non smoking is displayed is transmitted to the portable terminal 8 ₁ to 8 _N. Therefore, for example, by installing _{one of} the portable terminals 8 _{1 to} 8 _N at a prominent position in the house, it is possible to notify that the home is non-smoking when there is a visitor. it can. Further, for example, the mother operates his or her own portable terminal 8 _n to transmit the dinner time and menu as terminal data to the STB 7. In this case, in STB 7, time or dinner menu is displayed is transmitted to the portable terminal 8 ₁ to 8 _N.
Therefore, a child or a father can recognize the dinner time and menu. Further, for example, the father operates his / her mobile terminal 8 _n and transmits to the STB 7 as terminal data that he / she will go on a business trip. In this case, STB7
In, that the father is traveling is displayed is transmitted to the portable terminal 8 ₁ to 8 _N. Therefore, the child or mother can recognize that the father is on a business trip.
In addition, for example, the STB 7 may obtain, from the Internet 2 or the like, local information such as a local weather forecast where the user lives, and transmit the information to the mobile terminal 8 _n . .

The STB 7 can also distribute the display format data and the content data by attaching a predetermined ID (hereinafter, referred to as a distribution ID as appropriate) for specifying the STB 7. In this case, by preventing the portable terminal 8 _n from receiving data other than the display format data and the content data to which the predetermined distribution ID is attached, for example, the STB installed in the next house is the same as the STB 7. Even if the display format data and the content data are distributed using the frequency band described above, the display format data and the content data can be prevented from being received.

Further, although not particularly mentioned in the present embodiment, the EPG data stored in the HD 14 is always updated to the latest one. That is, for example, when the old EPG data is stored in the HD 14 for the same program, the new EPG
When data is received, new EPG data is stored (overwritten) in the HD 14 instead of old EPG data. Whether the EPG data is new or old can be determined based on, for example, update information.

[0063]

As described above, according to the data distribution apparatus and the data distribution method of the present invention, data transmitted via a predetermined transmission medium is received, and predetermined extraction data is extracted from the data. On the other hand, terminal data transmitted from a plurality of terminals is received. Then, the extracted data and the terminal data are distributed to a plurality of terminals. Therefore, for example, it is possible to provide, from among a large amount of program arrangement information, information necessary for displaying an EPG, and also to simultaneously provide information such as that a family member has made a recording reservation for a program.
