Embodiment approach 1

[0076] FIG. 1 is a configuration diagram showing Embodiment 1 of a data broadcast program TS transmitting apparatus according to the present invention installed in a broadcasting station.

[0077] The data broadcasting section TS transmitting device includes a receiving unit 101 , a determination list storage unit 102 , a separation and determination unit 103 , and a replacement and synthesis unit 104 .

[0078] The reception unit 101 receives a data broadcast program TS distributed through the network from another broadcast station 111 , and notifies the separation determination unit 103 of the received data broadcast program TS.

[0079] In other broadcasting stations 111, the data broadcasting program TS is distributed to distribution target broadcasting stations based on the network distribution list shown in FIG. 2 . In the network distribution list 201, a data broadcast program name column 202, a PID (Packet Identifier) ​​column 203, and a distribution destination column...

Embodiment approach 2

[0115] FIG. 9 is a configuration diagram showing Embodiment 2 of a data broadcast program TS transmitting apparatus according to the present invention.

[0116] This data broadcast program TS transmission device includes a reception unit 101 , a judgment list storage unit 102 , a separation and judgment unit 103 , a replacement and synthesis unit 104 , and a program element storage unit 901 . The same reference numerals are assigned to the same components as those in the above-mentioned first embodiment, their descriptions are omitted, and only the specific components of this embodiment will be described.

[0117] The reception unit 101 receives the data broadcast program TS indicated by the data broadcast program content information 301 distributed through the network from another broadcast station 111 as in the first embodiment described above.

[0118] The determination list storage unit 102 stores the selection list 401 shown in FIG. 4 together with the replacement list sh...

Embodiment approach 3

[0138] Next, Embodiment 3 of the data broadcast program TS transmitting apparatus according to the present invention will be described.

[0139] In the above-mentioned second embodiment, the data broadcasting program elements distributed through the network were replaced by the data broadcasting program elements produced by the station, but in this embodiment, the data broadcasting program elements distributed through the network are additionally produced by the station. elements of data broadcasting programs.

[0140] In addition, since the configuration diagram of this embodiment is the same as the configuration diagram of Embodiment 2 described above, it will be described using FIG. 9 .

[0141] The receiving unit 101 receives the data broadcast program TS indicated in the data broadcast program content information 301 distributed through the network in the same manner as in the second embodiment described above.

[0142] The determination list storage unit 102 stores the ...

Abstract

A data broadcast program TS transmission apparatus outputs a data broadcast program TS transmitted by the local broadcast station having the apparatus in accordance with a data broadcast program TS delivered by a second broadcast station via a network. A judgment list storage block stores a selection list containing data representing whether a received data broadcast program element is to be included in the data broadcast program TS of the local station, a replacing list for replacing the data broadcast program element with a local broadcast station program element prepared by the local broadcast station, etc. A separation judgment block separates a TS packet from the received data broadcast program TS and referencing the selection list, reports to a replacement / synthesis block those to be included in the data broadcast program TS of the local broadcast station. Furthermore, if there is a data broadcast program element to be replaced, the separation judgment block reports it to the replacement / synthesis block. The replacement / synthesis block reads out from the program element storage block a local broadcast station program element which the replacement / synthesis block has been instructed to replace, generates a TS packet, and outputs it as a local broadcast station data broadcast program TS together with the selected TS packet to a multiplexing apparatus.

Description

[0001] This application is a divisional application of the invention patent application with the application number 02801839.7, the application date is April 5, 2002, and the invention title is "data stream sending device and its method and distribution system". technical field [0002] The present invention relates to a data broadcast program TS transmission device and a distribution device for transmitting a data broadcast program TS in which content of a data broadcast program is multiplexed in digital broadcasting. technical background [0003] With the development of digital broadcasting, a large amount of digital broadcasting program contents are produced, and digital broadcasting programs TS are multiplexed in TS from each broadcasting station along with broadcasting programs and broadcasted. [0004] In current terrestrial television broadcasting, a broadcast program produced by a main station is distributed to local stations, and the local stations broadcast the broa...
