In addition, in the selection list 401, description of data broadcast programs other than the data broadcast program of weather information is omitted, but other data broadcast programs broadcast on one day may be described collectively, for example. A selection list may be created for each data broadcast program.

  The separation determination unit 103 separates the TS packet from the data broadcast program TS notified from the reception unit 101. Within the broadcast time described in the broadcast time column 403 of the selection list 401 stored in the determination list storage unit 102, the PID of the separated TS packet matches the PID described in the PID column 404 of the selection list 401. In this case, when “1” is described in the selection flag column 405 of the selection list 401, the separated combining unit 104 is notified of the separated TS packet. When “0” is written in the selection flag column 405, the separated TS packet is discarded.

The replacement combining unit 104 outputs the TS packet notified from the separation determining unit 103 to the multiplexing device 121 as the data broadcast program TS of the local station.
In this embodiment, since all TS packets of data broadcast program elements included in the data broadcast program TS distributed from other broadcast stations 111 are selected, the distributed data broadcast program TS is selected. Is output to the multiplexer 121 as it is.

Further, the replacement synthesis unit 104 may rewrite and output the PID attached to the notified TS packet.

When the separation determination unit 103 receives the notification of the data broadcast program TS from the reception unit 101, the separation determination unit 103 determines whether or not the current time is within the broadcast time 403 of the selection list 401 stored in the determination list storage unit 102. (S602). If the time is outside the broadcast time, the process returns to S602. If the time is within the broadcast time, the PID of the TS packet separated from the notified data broadcast program TS is the PID 404 in which the selection flag 405 of the selection list 401 is “0”. It is determined whether or not they match. (S604).

If they match, the process returns to S602. If they do not match, it is determined whether or not the PID of the separated TS packet matches the PID 404 of which the selection flag 405 of the selection list 401 is “1” (S606). If they do not match, the process returns to S602, and if they match, the TS packet is notified to the replacement synthesis unit 104.
The replacement synthesizing unit 104 outputs the notified TS packet as the data broadcast program TS of its own station to the multiplexing apparatus 121 (S608), and returns to S602.

In the present embodiment, a case where a selection list as shown in FIG. 7 is stored in the determination list storage unit 102 will be described.
In the selection list 701, the selection flag “1” indicates that the TS packet of the PID “100” of the data broadcast program element is selected from the data broadcast program TS of the data broadcast program “weather information” distributed on the network. The selection flag “0” indicates that the TS packet with the PID “101” of the data broadcast program element is not selected.

The separation determination unit 103 refers to the selection list 701, notifies the replacement combining unit 104 of the TS packet with the PID “100” of the data broadcast program TS distributed from the other broadcasting station 111, and the TS with the PID “101”. Discard the packet.
The replacement synthesis unit 104 transmits only the TS packet with the PID “100” to the multiplexing device 121 as the data broadcast program TS of the “meteorological information” of the local station.

  As a result, the receiver that receives the data broadcast program TS broadcast from the multiplexing device 121 views the data broadcast program screen shown in FIG. The screen 801 is the same as the screen 501 in FIG. 5, and the screen 802 is the same as the screen 502 in FIG. Since the TS packet of PID 101 is not selected, the screen 503 shown in FIG. 5 cannot be viewed in this data broadcast program.

  In the present embodiment, the data broadcast program TS transmission device refers to the data broadcast program content information 301 to create a selection list. However, the data broadcast program content information 301 includes a data broadcast for each component. In the program TS transmission device, the availability information on whether or not to include in the data broadcast program content of one broadcasting station may be described. In this way, the data broadcast program TS transmission device can easily create a selection list with reference to the availability information.

When replacing the entire module, the pre-replacement resource name field 1006 and the post-replacement resource name field 1007 are blank.

The pre-replacement resource name column 1006 describes the resource name of the distributed data broadcast program element, and the post-replacement resource name column 1007 describes the resource of the data broadcast program element produced by the own station. This shows that the distributed data broadcast program element is replaced with the resource of the data broadcast program element produced by the own station.
The program element storage unit 901 stores modules and resources of data broadcast program elements produced by the data broadcast program content production device 902 of the own station.

  FIG. 11 shows a data broadcast program element 1101 with PID “101” and module name “0010” stored in the program element storage unit 901, and a resource name “CHIHOU.BML” with PID “100” and module name “0001”. Data broadcast program element 1102 and a data broadcast program element 1103 having the same resource name “CHIHOU_CHIZU.PNG”.

  The separation determination unit 103 separates the TS packet when the data broadcast program TS distributed from the other broadcasting station 111 is notified via the reception unit 101. The selection list 401 stored in the determination list storage unit 102 is referred to determine whether or not the current time is within the broadcast time. If the current time is within the broadcast time, the PID whose selection flag is “1” is determined. And whether the PID of the separated TS packet matches. If they match, the replacement list 1001 stored in the determination list storage unit 102 is referenced to determine whether or not a PID that matches the PID of the separated TS packet is described. When not described, the TS packet is notified to the replacement synthesis unit 104. When it is described, it is determined whether or not the module name of the replacement list 1001 matches the module name of the separated TS packet. When they match, it is determined whether or not the resource name field before replacement and the resource name field after replacement are blank. If it is blank, the replacement synthesis unit 104 is notified of the PID and module name, and a replacement instruction is given.

When the resource name described in the pre-replacement resource name field of the replacement list 1001 matches the resource name of the separated TS packet, the separation determination unit 103 describes the PID, the module name, and the resource name field after replacement. The resource name is notified to the replacement synthesis unit 104 and a replacement instruction is given.
When receiving the replacement instruction, the notification of the PID and the module name from the separation determination unit 103, the replacement synthesis unit 104 reads the module stored in the program element storage unit 901 and generates a TS packet. In addition, when a replacement instruction, a PID, a module name, and a resource name are received, the resource stored in the program storage unit 901 is read and a TS packet is generated. The replacement synthesizer 104 discards the TS packet before replacement instructed to be replaced by the separation determination unit 103. The replacement synthesis unit 104 outputs the TS packet notified from the separation determination unit 103 and the TS packet generated by the replacement instruction to the multiplexing device 121 as its own data program broadcast TS.

Various screens 1201, 1202, and 1203 can be viewed.
The screen 1201 uses data broadcast program elements distributed from other broadcast stations 111 as they are, and the screens 1202 and 1203 are produced by the data broadcast program content production device 902 of the own station.

The data broadcast program content production device 902 produces modules and resources that are data broadcast program elements unique to the local station.
Next, the operation of the present embodiment will be described with reference to the flowchart shown in FIG.
First, upon receiving notification of the data broadcast program TS from another broadcast station 111, the separation determination unit 101 determines whether or not the current time is within the broadcast time in the selection list 401 (S1302). In this case, the program waits until the broadcast time, and if it is within the broadcast time, it is determined whether or not the PID of the TS packet of the separated data broadcast program matches the PID of the selection list 401 with “1” (S1304). . If not, the TS packet is discarded (S1306), and the process returns to S1302. If they match, it is determined whether or not the PID of the separated TS packet matches the PID of the replacement list 1001 (S1308). When they match, it is determined whether or not the module name of the separated TS packet matches the module name of the replacement list 1001 (S1310).

If they match, it is determined whether or not the resource name in the replacement list 1001 is blank (S1312). If it is blank, the replacement synthesis unit 104 is notified of the PID and module name, instructed to replace the module (S1314), and the process proceeds to S1322.
When the resource name is not blank, it is determined whether or not the resource name of the separated TS packet matches the resource name before replacement in the replacement list 1001 (S1316). If they match, the replacement synthesizing unit 104 is notified of the PID, the module name, and the replaced resource name, instructed to replace the resource, and the process proceeds to S1322.

If NO in S1308, S1310, or S1316, the separation determining unit 103 notifies the replacement combining unit 104 of the separated TS packet, and proceeds to S1324.
In S1322, the replacement composition unit 104 reads out the module or resource instructed to be replaced from the program element storage unit 901 (S1322).
The replacement synthesizing unit 104 converts the read module or resource into a TS packet, and outputs it to the multiplexing apparatus 121 as the data broadcast program TS of the local station together with the notified TS packet (S1324), and returns to S1302.

  When the separation determination unit 103 is notified of the data broadcast program TS distributed from the other broadcasting station 111 from the reception unit 101, the separation determination unit 103 refers to the selection list 401 stored in the determination list storage unit 102 and is distributed. A data broadcast program element included in the data broadcast program TS is selected, and the replacement list 1001 is referenced to notify the replacement synthesis unit 104 of a module or resource replacement instruction.

The separation determination unit 103 refers to the additional list 1401 stored in the determination list storage unit 102, and when the broadcast time zone described in the broadcast time column 1403 is reached, the PID and module name for identifying the data broadcast program element Or the PID, the module name, and the resource name are notified to the replacement synthesis unit 104 to instruct the addition of the data broadcast program element.
When the replacement synthesis unit 104 receives an additional instruction from the separation determination unit 103, the replacement synthesis unit 104 reads the notified module or resource from the program element storage unit 901. A TS packet is generated from the read module or resource. The generated TS packet is output to the multiplexing apparatus 121 as the data broadcast program TS of the local station together with the distributed TS packet notified from the separation determination unit 103 and the TS packet according to the replacement instruction.

As a result, the receiver that has received the data broadcast program TS can view a screen as shown in FIG.
A screen 1601 is a data broadcast program element distributed from another broadcast station 111, and a screen 1602 and a screen 1603 are produced and replaced by the data broadcast program content production device 902 of the own station. 1604 and a screen 1605 are produced and added by the data broadcast program content production device 902 of the own station.

Next, operations unique to the present embodiment will be described with reference to the flowchart shown in FIG. Note that the operation of selecting a data broadcast program element from the distributed data broadcast program TS and the operation of replacing the data broadcast program element are the same as those in the second embodiment, and a description thereof will be omitted.
When the additional list 1401 is stored in the determination list storage unit 102, the separation determination unit 103 waits for the broadcast time described in the additional list 1401 (S1702), and refers to the additional list 1401 for addition. It is determined whether or not a data broadcast program element to be described is described (S1704). If it is not described, the process is terminated, and if it is described, the PID, module name, and resource name for identifying the data broadcast program element are notified to the replacement synthesizing unit 104, and an addition is instructed (S1706).

Upon receiving an instruction to add a data broadcast program from the separation determination unit 103, the replacement synthesis unit 104 reads out a module or resource stored in the program element storage unit 901, generates a TS packet, and generates a data broadcast program of its own station. Multiplex to TS and output to multiplexer. (S1708).
The separation determination unit 103 determines whether or not it is within the broadcast time of the additional list 1401 (S1710), ends the process if it is outside the broadcast time, and returns to S1704 if it is within the broadcast time.

(Embodiment 4)
FIG. 18 is a configuration diagram of Embodiment 4 of the data broadcast program transmitting apparatus according to the present invention. The data broadcast program sending device is almost the same as the configuration of the first embodiment.
The local data broadcast program content production device 1801 produces modules and resources that are unique data broadcast program elements, and notifies the data broadcast program TS output unit 1802 of them.

The data broadcast program TS output unit 1802 converts the modules and resources notified from the data broadcast program content production device 1801 into TS packets and outputs them to the replacement synthesis unit 104.
In the same manner as in the first embodiment, replacement synthesis section 104 uses TS packets delivered from other broadcast stations 111 notified from separation determination section 103 and data broadcast program TS output from data broadcast program TS output section 1802. The packets are multiplexed and output to the multiplexer 121 as the data broadcast program TS of the local station.

(Embodiment 5)
Next, a fifth embodiment of the data broadcast program TS transmission device according to the present invention will be described.
Since this data broadcast program sending apparatus has the same configuration as that described in the second embodiment, it will be described with reference to the block diagram shown in FIG.

FIG. 19 is a diagram showing an example of the contents of the data broadcast program TS transmitted from another broadcast station and one broadcast station having the data broadcast program TS transmission device.
The upper part of FIG. 19 shows the contents of a data broadcast program TS that another broadcast station broadcasts as a data broadcast program of another broadcast station together with the net distribution. The data broadcasting program 1901 broadcasted by the other broadcasting station 111 includes the ES (elementary stream) 1911 of the main part of the data broadcasting program, the ES 1912 of the CM for national broadcasting, the ES 1913 of the CM for other broadcasting station 111, and the CM processing timing. And an EM (event message) ES 1914.

The data broadcast program main part ES 1911 includes a data broadcast program main part module 1921. The module 1921 is a TS packet with a PID “100” and a module name “0001”, and is a data broadcast program element constituting a data broadcast program.
The national CM ES 1912 includes a national CM module 1922. The module 1922 is a TS packet with a PID “101” and a module name “0000”, and is a data broadcast program element constituting a data broadcast program. This nationwide CM is assumed to be viewed at, for example, one broadcasting station of the Internet distribution destination together with the main part of the data broadcasting program.

  The other broadcast station 111 CM ES 1913 includes other broadcast station 111 CM modules 1923 and 1924. The module 1923 is a TS packet with a PID “102” and a module name “0000”, and the module 1924 is a TS packet with a PID “102” and a module name “0001”. It is a data broadcast program element constituting a data broadcast program. The other broadcast station 111 CM is assumed to be viewed by a receiver that directly receives the broadcast of the other broadcast station 111.

  The EM ES 1914 representing CM processing timing includes EMs 1925, 1926, and 1927 representing CM processing timing. EM 1925 is a TS packet with PID “103” and EMID (event message identifier) “0000”, EM 1926 is a TS packet with PID “103” and EMID “0001”, and EM 1927 is The TS packet is assigned with PID “103” and EMID “0002”. EM 1925, 1926, and 1927 are data broadcast program elements constituting data broadcast. The EM 1925 is a trigger for informing the receiver of the timing for processing the CM module 1923 for the other broadcasting station 111. The EM 1926 is for informing the receiver of the timing for processing the national CM module 1922. The EM 1927 is a trigger for informing the receiver of timing for processing the CM module 1924 for the other broadcasting station 111.

In a receiver that directly receives a broadcast of another broadcast station 111, when a data broadcast program, for example, shopping information is received, the data broadcast program main part module 1921 is displayed on the screen during the time when the main part of the data broadcast program is being broadcast. indicate.
When the EM 1925 representing the CM processing timing is received, the module 1923 of another broadcasting station CM 1913 is stored in the memory or stored in the memory and displayed on the screen together.

The EM 1926 represents the timing of storing the module 1922 of the national CM 1912 in the memory or the screen display, and the EM 1927 represents the timing of storing the CM module 1924 for the other broadcasting station 111 in the memory or the screen display. ing.
In the ES 1914 of the EM representing the CM processing timing, the processing start timings of the modules of the national CM ES 1912 and the CM 1919 for the other broadcasting stations 111 are the same ES 1914, but may be different ESs. That is, another PID may be attached.

In this embodiment, the processing of the CM modules 1922, 1923, and 1924, that is, the timing of storage in the memory and the screen display is represented by EM 1926, 1925, and 1927, but EM is omitted and each CM is omitted. The modules 1922, 1923, and 1924 may be stored in the memory or displayed on the screen at the timing of reception.
Similarly, when the version of the module 1921 of the main part of the data broadcasting program is updated, the timing of the processing of the CM modules 1922, 1923, and 1924 may be used, or the CM modules 1922, 1923, and 1924 may be omitted. The processing timing may be set when the version is updated.

Further, when only the CM modules 1922, 1923, and 1924 are stored in the memory, the screen display control of the CM module 1922 and the like is performed by the module 1921 of the main part of the data broadcasting program. In addition, it may be displayed on the screen simultaneously with storage in the memory.
The receiving unit 101 of the data broadcast program TS transmission device receives the net distribution of the data broadcast program TS of the data broadcast program 1901 from another broadcast station 111.

The determination list storage unit 102 stores a selection list shown in FIG. 20 and a replacement list shown in FIG.
In the selection list 2001, a selection flag 2003 is described for the data broadcast program element of the shopping information 2002 distributed from other broadcast stations 111. The data broadcast program element is identified by PID 2004, module name, or EMID 2005. The ES module of the data broadcasting program main part and the ES module of the CM are identified by the PID and the module name, and the EM is identified by the PID and the EMID.

Referring to this selection list 2001, separation determination section 103 discards module 1924 with PID “102” and module name “0001” and EM 1927 with PID “103” and EMID “0002”. The remaining selected data broadcast program elements are notified to the replacement composition unit 104.
The replacement list 2101 describes replacement instructions for data broadcast program elements of the shopping information 2102 distributed from other broadcast stations 111. In this replacement list 2101, it is instructed to replace the data broadcast broadcast program element identified by the PID “101” and the module name “0000”.

The separation determination unit 103 notifies the replacement synthesis unit 104 of the PID “101” and the module name “0000”, and instructs replacement.
The program element storage unit 901 stores the data broadcast program element of the CM for the own station identified by the PID “101” and the module name “0000” produced by the data broadcast program content production apparatus 902.

Based on the replacement instruction notified from the separation determination unit 103, the replacement composition unit 104 reads out the data broadcast program element produced by the data broadcast program content production device 902 of the own station stored in the program element storage unit 901. The TS packet is generated and replaced with the TS packet distributed from the other broadcast station 111 notified.
Using this replacement list 2101, the replacement synthesis unit 104 replaces the other broadcast station 111 CM module 1923 that has been distributed with the self-station CM module produced by itself.

  The lower part of FIG. 19 shows the contents of the data broadcast program 1902 output from the data broadcast program TS transmission device based on the data broadcast program 1901 distributed on the network. The data broadcast program 1902 is composed of an ES 1911 of the main part of the data broadcast program, an ES 1912 of the national CM, an ES 1931 of the local CM, and an ES 1932 of the EM indicating the CM processing timing. Here, ESs, modules, and EMs denoted by the same reference numerals as those in the upper part of FIG. 19 are the same as the data broadcast program elements distributed from other broadcast stations 111.

The own-station CM ES 1931 is produced by the data broadcast program content production apparatus 902, and the own-station CM module 1941 is composed of TS packets generated by the replacement synthesis unit 104.
The EM ES 1932 indicating the CM processing timing is obtained by discarding the EM ES 1914 indicating the CM processing timing from the EM ES 1914 indicating the distributed CM processing timing.

The self-station CM module 1941 is assumed to be viewed by a receiver that directly receives the broadcast of one broadcast station.
In the present embodiment, the distributed CM module 1922 is used as it is, but it is of course possible to replace it with a CM module for the own station.
Note that the operation of a receiver that receives a broadcast from one broadcast station is substantially the same as the operation of a receiver that receives a broadcast from another broadcast station 111 described above.

In this embodiment, the other broadcast station CM module 1924 and the EM 1927 representing the CM processing timing are discarded, but may be realized by replacing them with a NULL packet, for example.
Further, in the present embodiment, only the discarding of the EM has been described. However, it is of course possible to add the CM module for the own station and add the EM correspondingly.

  In the present embodiment, the data broadcasting program content information is replaced by one broadcasting station so that the other broadcasting station CM module 1923 is replaced with the own broadcasting station CM module 1941 and the other broadcasting station CM module 1924 is discarded. In other broadcasting stations 111, designations that can be replaced, cannot be replaced, can be deleted, and cannot be deleted are described in the data broadcast program content information for each component. It may be. In the data broadcast program TS transmission apparatus that has received the data broadcast program content information, a selection list or a replacement list is created in accordance with the designation that the data broadcast program content information can be replaced.

(Embodiment 6)
Next, a sixth embodiment of the data broadcast program TS transmission device according to the present invention will be described. In the present embodiment, a specific example of module or resource replacement described in the second embodiment will be described. Therefore, description will be made with reference to the configuration diagram of FIG.

The replacement synthesizer 103 receives the notification of the TS packet of the data broadcast program TS distributed from the other broadcast station 111 from the other broadcast station 111 that is included in the data broadcast program content of the local station.
Further, the replacement synthesis unit 103 receives a replacement instruction for the module with the packet PID “101” and the module name “0010” from the separation determination unit 103.

  FIG. 22 shows a continuous data broadcast program TS of TS packets notified to the replacement synthesis unit 103. Two modules of PID “101” and module name “0010” before replacement are included as modules 2203 and 2204 in one cycle 2202 of the carousel of the data broadcast program TS2201. The module 2203 is composed of two TS packets 2205 and 2206, and the module 2204 is composed of two TS packets 2207 and 2208. That is, the modules 2203 and 2204 have a size of two TS packets, and are transmitted twice in each cycle 2202 once each.

Whether the replacement synthesizing unit 103 holds the band of the data broadcast program TS transmitted by the own station or the number of transmissions per cycle for the module or resource instructed to replace the data broadcast program TS distributed on the network Either of these is preset.
In the case where band retention is set in the replacement composition unit 103, when the replacement composition unit 103 receives a replacement instruction, the replacement composition unit 103 reads out the module of the instructed PID and module name stored in the program element storage unit 901, and TS packet And the TS packets 2205, 2206, 2207, and 2208 constituting the modules 2203 and 2204 before the replacement of the notified TS 2201 are replaced with the generated TS packets.

At this time, when the size of the module after replacement is small or large, the number of TS packets may change, so the number of modules transmitted in one cycle changes.
FIG. 23A shows the data broadcasting program TS2301 when the module size after replacement is halved, and FIG. 23B shows data broadcasting when the module size after replacement is doubled. The program TS2302 is shown.

In the data broadcast program TS2301, the replaced module is composed of one TS packet. Four modules of PID “101” and module name “0010” after replacement are included as modules 2304, 2305, 2306, and 2307 in one cycle 2303 of the carousel.
In the data broadcast program TS2302, the replaced module is composed of four TS packets. One module with the PID “101” and the module name “0010” after replacement is included as one module 2309 in one cycle 2308 of the carousel. The module 2309 is composed of four TS packets 2310, 2311, 2312, and 2313.

When the replacement synthesis unit 103 is set to hold the number of transmissions per cycle, when the replacement synthesis unit 103 receives a replacement instruction, the replacement PID and module name stored in the program element storage unit 901 are received. These modules are read out, TS packets are generated, and the size of the module before replacement is compared with the size of the module after replacement.
For example, when the module size after replacement is halved, in the data broadcast program TS2201 before replacement, two modules 2203 and 2204 were included in one cycle 2202, so the data broadcast program after replacement The TS also includes two modules after replacement.

For this reason, the replacement combining unit 103 replaces half of the TS packets constituting the module before replacement with a NULL packet.
When the module size after the replacement is doubled, the data broadcast program TS2201 before the replacement includes two modules 2203 and 2204 in one cycle 2202, so the data broadcast program TS after the replacement But make sure to include two modules after replacement.

Therefore, the replacement combining unit 103 replaces all TS packets constituting the module before replacement with the TS packets constituting one module after replacement, and inserts one module after replacement in one cycle.
FIG. 24A shows a data broadcast program TS2401 when the module size after replacement is halved, and FIG. 24B shows data broadcast when the module size after replacement is doubled. The program TS2402 is shown.

In the data broadcast program TS2401, the replaced module is composed of one TS packet. The NULL packet 2406 is replaced with the modules 2404 and 2405 with the PID “101” and the module name “0010” after replacement in one cycle 2403 of the carousel, and the NULL packet 2407 is replaced after the module 2405.
In the data broadcast program TS2402, the replaced module is composed of four TS packets. Two modules 2409 and 2410 after replacement are included in one cycle 2408 of the carousel. The module 2409 is composed of four TS packets 2411, 2412, 2413, and 2414, and the module 2410 is composed of four TS packets 2415, 2416, 2417, and 2418. At this time, since the number of TS packets after replacement is larger than the TS packets 2205 to 2208 before replacement, extra TS packets after replacement are inserted in one period 2408. In this way, the number of modules appearing in one cycle 2403 and 2408 can be held. For this reason, the band changes.

When the size of the module or resource instructed for replacement matches the size of the module or resource to be replaced stored in the program element storage unit 901, the retention of the bandwidth and the retention of the number of transmissions per cycle are the same. Result.
(Embodiment 7)
Next, a seventh embodiment of the data broadcast program sending apparatus according to the present invention will be described. This embodiment is the same as the configuration of the second embodiment, and will be described with reference to the configuration diagram of FIG.

  In this embodiment, a module or resource that is a data broadcast program element distributed on the network is replaced with a module or resource that is a data broadcast program element produced by the own station, and is the same as in the second embodiment. However, the module or resource is not displayed on the display screen by the receiver that has received the transmission of the data broadcast program TS, but is used for control of the receiver.

An upper part of FIG. 25 shows an example of a data broadcast program element distributed from another broadcast station 111, and a lower part shows an example of a data broadcast program element output from the data broadcast program TS sending device. Yes.
The distributed data broadcast program element 2501 includes a resource 2511 and a program table 2521 that is a resource.

  In this resource 2511, a script 2512 representing channel selection is described. For example, with this script 2512, the receiver in the area of the other broadcasting station 111 actually selects the program number “0222” and performs the channel selection operation, but does not describe the actual program number of the channel selection destination. Thus, a temporary program name 2513 is described. The data broadcast program element 2501 includes a program table 2521 that associates the temporary program name 2513 “SERVICE_A” with the actual program number “0222”.

In addition, the program table 2521 associates temporary program names 2522 with actual program numbers 2523.
If the actual program number is directly described in the resource 2511, it becomes necessary to replace the resource 2511 in the data broadcast program TS transmission device of the broadcast station that has been distributed using the resource 2511 as a data broadcast program element. The actual program number is used for channel selection in the broadcast area of another broadcast station 111, and cannot be used in one broadcast station. As described above, by separately using the program table 2521 in which the temporary program number 2522 and the actual program number 2523 are associated with each other, the resource 2511 is a versatile data broadcast program element.

  In one broadcasting station equipped with the data broadcasting program TS transmission device, a program table in which an actual program number used for channel selection and a temporary program name used by a receiver in the area of its own station replacing the program table 2521 is associated with data broadcasting. It is produced by the program content production apparatus 902. This program table is the program table 2531 included in the data broadcast program element 2502 output from the data broadcast program TS transmission device shown in the lower part of FIG.

The program table 2531 is stored in the program element storage unit 901. The program table 2531 is assigned the same PID and module name as the distributed program table 2521, and the resource name may be unique to the local station.
The determination list storage unit 102 stores a replacement list describing that the program table 2521 should be replaced with the program table 2531.

The receiving unit 101 receives the data broadcast program TS including the data broadcast program element 2501 distributed from the other broadcast station 111 and notifies the separation determination unit 103 of the data broadcast program TS.
The separation determination unit 103 is a data broadcast program element that separates the notified data broadcast program TS into TS packets and includes the data broadcast program TS in its own data broadcast program TS according to the selection list stored in the determination list storage unit 102. The TS packet constituting the module or resource is notified to the replacement synthesis unit 104.

The separation determination unit 103 also instructs the replacement synthesis unit 104 to replace the program table 2521 that is a resource among the notified TS packets in accordance with the replacement list.
The replacement synthesis unit 104 reads the program table 2531 stored in the program element storage unit 901 according to the replacement instruction, and generates a TS packet. Together with the notified TS packet, the TS packet to be replaced is replaced, multiplexed on the data broadcast program TS, and output to the multiplexing device 121.

The data broadcast program TS including the data broadcast program element 2502 shown in the lower part of FIG. 25 is output from the data broadcast program TS transmission device.
The data broadcast program element 2502 includes a program table 2531 in place of the distributed program table 2521.
The resource 2511 is used as it is. “SERVICE_A” of the temporary program name 2513 is used for channel selection in the receiver that has received the transmission of the actual program number “0666” from one broadcast station with reference to the program table 2531.

As described above, since the program number to be referred to in the resource 2511 is indirectly referenced, only the program table associated with the change item is replaced without replacing the resource 2511. Therefore, efficient data can be obtained. Broadcast program elements can be changed.
Note that the program tables 2521 and 2531 may be configured in a text format or a binary format. Further, although the resource format is used in the present embodiment, it may be broadcast in the module format.

Further, in each of the above embodiments, it has been described that the other broadcast stations distribute only the data broadcast program TS to the data broadcast program TS sending device of one broadcast station, but the data broadcast program TS is included in the broadcast program TS. You may make it deliver what multiplexed.
Further, in each of the above-described embodiments, the data broadcast program TS transmission device is shown in the configuration diagrams of FIGS. 1, 9, and 18, but it may be realized by a program that causes the function of each component to be performed by a computer. Good. Further, this program may be recorded on a computer-readable recording medium, and applied to a data broadcast program TS transmission device that transmits its own data broadcast program TS from a network-distributed data broadcast program TS. .

  Further, in each of the above embodiments, the data broadcast program TS transmission device receives the distribution of the first broadcast program TS according to the MPEG2 standard from another broadcast station and transmits the data broadcast program TS. Of course, it is also possible to receive a data stream consisting of a set of IP packets conforming to the IP (Internet Protocol) different from the TS conforming to the MPEG2 standard and send out a data broadcast program data stream.

  The data stream transmission apparatus according to the present invention can use the first data broadcasting program TS distributed from other broadcasting stations when broadcasting the data broadcasting program by multiplexing it with the digital broadcasting broadcasting program. Therefore, it is possible to employ the broadcasting station as a data broadcasting program TS transmission device that is more efficient than the conventional method of producing data broadcasting programs by all stations.
