Description

The present invention relates to a transmission system in digital broadcasting.

  Terrestrial digital broadcasting is also transmitted to radio wave shielding spaces such as buildings, underground malls, and subways, so that digital terrestrial broadcasting can be received everywhere. Therefore, 1-segment partial reception service (hereinafter referred to as 1Seg) broadcasting for mobile phones and mobile terminals has become widespread. One seg broadcasting (hereinafter referred to as one seg area) broadcasting for narrow areas (areas) such as administrative units is under experiment.

  Broadcast stations are divided into performance stations that produce broadcast programs and sequentially output them as electrical signals along the program (program guide), and transmitters that transmit them as radio waves.

  Conventionally, in order to perform one-segment broadcasting, Internet-Protocol-Network (IP network) such as Virtual-Private-Network (VPN) is always occupied, and File-Transfer-Protocol (such as VPN) is transmitted from the parent broadcasting station to the area broadcasting station. Transport-Stream (TS) data was sent in real time by FTP) and broadcasted by an area broadcasting station. As the number of bases in the local broadcast area increased, the required IP network bandwidth also increased. Alternatively, a local server is placed at each site in the local broadcast area, and the content registered in advance in the local server is loop-played and broadcast.

Patent Publication 2006-101278

  In one seg area broadcasting, an area broadcasting station automatically transmits one seg content and broadcasts in one seg area.

  In order to achieve the above object, the present invention has a server that stores a transport stream (TS) for one-segment content before broadcasting in at least one or more area broadcasting stations, There is a server for storing the broadcast time and broadcast material ID as broadcast operation data of the area broadcast station, and each area broadcast station server periodically transmits the parent broadcast station's address via the Internet Protocol Network (IP network). When the broadcast operation data of the own station is updated by monitoring the inside of the server, the broadcast operation data is downloaded from the parent broadcast station server by File Transfer Protocol (FTP), and the material ID described in the broadcast operation data is downloaded. TS for one-seg contents corresponding to the above is downloaded from the parent broadcast station server via the IP network, and the area broadcast station server uses the broadcast operation data of the area broadcast station. When the corresponding time is reached according to the broadcast time and broadcast material ID, the one-segment content TS corresponding to the material ID described in the broadcast operation data of the area broadcast station is automatically transmitted, and the broadcast operation of the area broadcast station is performed. A broadcast transmission system that deletes a previously broadcasted TS for one-seg content having a material ID that does not exist in the broadcast time and the broadcast material ID that is data.

  As described above, according to the present invention, in one seg area broadcasting, a server in an area broadcasting station downloads broadcast operation data and a TS for one seg content from the parent broadcast station server, and according to the broadcast operation data, the one seg content TS is automatically transmitted, and TS broadcasted in the past is deleted.

The block diagram which shows the broadcast transmission system of one Example of this invention. The schematic diagram which shows the broadcast operation data of one Example of this invention

  An embodiment of the present invention will be described with reference to FIG. 1 of a block diagram showing a broadcast transmission system of an embodiment of the present invention and FIG. 2 of a schematic diagram showing broadcast operation data of an embodiment of the present invention.

  A block diagram 102 in FIG. 1 showing a broadcast transmission system according to an embodiment of the present invention is a server installed in a parent broadcast station. This server stores broadcast operation data 12 and 13 and one-segment content TS 11 to be distributed to each base station. Reference numeral 101 denotes a broadcast operation data creation terminal installed in the parent broadcast station. The broadcast operation data creation terminal 101 creates the broadcast operation data 12 and 13 of each area broadcast station in advance and stores them in the 102 parent broadcast station server. As shown in FIG. 2 of the schematic diagram showing the broadcast operation data of one embodiment of the present invention, the broadcast operation data 12 and 13 describe the broadcast time for one day broadcasted by the area broadcasting station and the broadcast material ID. Has been.

  The 201 area broadcast station server of the area broadcast station 1 is connected to the 102 parent broadcast station server by VPN. The 201 area broadcast station server periodically monitors 12 of the broadcast operation data for its own station in the 102 parent broadcast station server, and if there is a change, downloads it by the File Transfer Protocol (FTP) as the broadcast operation data 20. save. The 201 area broadcasting station server opens the downloaded broadcast operation data 20, and downloads 21 of the one-seg content TS of the material ID described in the broadcast operation data 20 from the 102 parent broadcast station server in advance by FTP. Save it.

Similarly, the 301 area broadcast station server of the area broadcast station 2 monitors 13 of the broadcast operation data for its own station in the 102 parent broadcast station server, and if there is a change, downloads it by FTP and broadcast operation data. 30 and the corresponding one-seg content TS 31 is downloaded in advance from the 102 parent broadcast station server by FTP and stored.
The area broadcast station servers 201 and 301 broadcast the stored video content from the transmitters 202 and 302 via the antennas 203 and 303 at the corresponding time according to the broadcast operation data of 20 and 30.

  As described above, according to the present invention, in one seg area broadcasting, a server in an area broadcasting station downloads its own broadcasting operation data and TS for one seg content from the parent broadcasting station server, and follows the broadcasting operation data. , 1Seg content is automatically transmitted and broadcasted in 1Seg area.

  Also, the instruction for downloading the TS for the one-segment content and the broadcast operation data of the area broadcast station from the parent broadcast station and the instruction for deleting the TS for the one-segment content are not necessary.

12, 13, 20, 30: Broadcast operation data,
11, 21, 31: TS for 1Seg content,
101: Broadcast operation data creation terminal,
102: Parent broadcast station server, 201, 301: Area broadcast station server,
202, 302: transmitter, 203, 303: antenna,
