Embodiment approach 1

[0078] figure 1 It 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.

[0079] The data broadcast program 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 .

[0080] 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.

[0081] Among other broadcast stations 111, according to figure 2 The shown network distribution list distributes the data broadcasting program TS to distribution target broadcasting stations. In the network distribution list 201, a data broadcast program name column 202, a PID (Packet Identifier) ​​column 203, and a distribution destination colu...

Embodiment approach 2

[0117] Figure 9 It is a configuration diagram showing Embodiment 2 of the data broadcast program TS transmitting apparatus according to the present invention.

[0118] 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.

[0119] 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.

[0120] The judgment list storage unit 102 will Figure 4The select list 401 shown with Figure 10 The substitution list...

Embodiment approach 3

[0140] Next, Embodiment 3 of the data broadcast program TS transmitting apparatus according to the present invention will be described.

[0141] 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.

[0142] In addition, since the configuration diagram of this embodiment is the same as that of Embodiment 2 above, using Figure 9 for clarification.

[0143] 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.

[0144] The determination list storage unit 102 stores the selection list 401 and the repl...

Abstract

A data broadcast program transport stream (TS) transmission device provided in a broadcast station, and for transmitting a data broadcast program TS based on a data broadcast program TS distributed over a network by another broadcast station. The data broadcast program TS transmission device stores a selection list that shows whether data broadcast program elements of the received data broadcast program are for inclusion in the data broadcast program TS of the broadcast station, and a replacement list that shows the replacement of data broadcast program elements for inclusion with local program elements produced in the broadcast station. A separation judgment unit separates TS packets from the received data broadcast program TS, refers to the selection list, and notifies the replacement execution unit of data broadcast program elements for inclusion. Furthermore, if data broadcast program elements judged for inclusion are shown for replacement in the replacement list, the separation judgment unit sends a replacement instruction to the replacement execution unit. The replacement execution unit reads the local program elements indicated in the replacement instruction from the program element storage unit, generates TS packets, and outputs the generated TS packets together with selected TS packets to a multiplexing device as the data broadcast program TS of the broadcast station.

Description

technical field [0001] 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 [0002] 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. [0003] In current terrestrial television broadcasting, a broadcast program produced by a main station is distributed to local stations, and the local stations broadcast the broadcast program as it is through a network. Similarly, the satellite broadcasting is received by the CATV station, and the signal is retransmitted from the CATV station to the CATV receiver of each household. [0004] However, in data broadcasting programs, distrib...
