Description

  The present invention relates to support information representing the operating state of a predetermined device provided in a relay base station, for example, an FPU receiver, when a video TS signal transmitted from an FPU transmitter is transmitted to a broadcast station via the relay base station. The present invention also relates to a data multiplexing device, a data separation device, and an FPU reception support information transmission device that can be TS-encapsulated and transmitted to a broadcasting station.

  In general, video / audio data from an FPU device mounted on a relay car or the like is transmitted to a broadcast station as a TS (Transport Stream in MPEG-2) signal, for example, via a relay base station provided on a mountain.

  The relay base station is equipped with at least radio wave receiving equipment such as a parabolic antenna, FPU (Field Pick-up Unit) receiver, TSL (Transmitter-Studio Link) transmitter, etc. In addition, a TSL receiver, an FPU control device, and the like are provided, and at least devices such as the FPU receiver provided in the relay base station are controlled by the FPU control device.

  By the way, for example, since the FPU receiver is controlled by the FPU control device, command information for controlling the device and status information which is a response from the device are exchanged between the FPU receiver and the FPU control device. Yes.

  Specifically, command information for controlling the device and status information that is a response from the device have a small amount of data. Therefore, in addition to the TS signal, the information is transmitted to the broadcasting station via a TCP / IP line such as an ISDN line. However, the support information data indicating the operation state of the device cannot be sent over a narrow-band TCP / IP line such as ISDN because the amount of data is large.

  In order to cope with this, a transmission system has been proposed in which data relating to support information such as an operation state having a large amount of data is transmitted as a TS signal having a large transmission capacity (see, for example, Patent Document 1).

Hereinafter, the flow of signals and data in the entire FPU transmission system will be described.
A video TS signal, which is FPU data transmitted from the FPU transmitter 2, is received by the FPU receiver 11 and sent to the data multiplexer 12, and at the same time, a predetermined device of the relay base station 3, that is, at least the operation of the FPU receiver 11. UDP data of support information representing the state and TCP data representing the status information are sent to the data multiplexer 12. The support information is output as a UDP frame by the FPU receiver 11.

  In this data multiplexer 12, the video TS signal is sent to the multiplexing unit 33, and the UDP data and TCP data are sent to the distribution unit 31, where the UDP data and the TCP data are distributed.

  Then, the UDP data is sent to the TS converter 32, and TS encapsulation is performed on the data of the UDP packet. That is, an identification part such as a data length, a pointer field, and a TS header is added to the data of the UDP packet, and the data of the UDP packet is captured and TS-encapsulated so as to have a predetermined number of bytes. The It is divided when the data of the UDP packet is large, and the head position of the data to be the next packet is indicated by a pointer field.

The TS-encapsulated UDP / TS signal is sent to the multiplexing unit 33 where it is multiplexed into the video TS signal. For example, multiplexing by time division is performed.
The multiplexed TS signal multiplexed is transmitted from the TSL transmitter 11 and received by the TSL receiver 21 of the broadcasting station.

That is, an identification part such as a TS header is removed from the UDP / TS signal to obtain UDP data as a packet. By the way, when a UDP packet is divided and sent, it is reconstructed into one packet. The UDP data is sent to the FPU control device 23 via the broadcast station side router 25.

  As for the video TS signal, the multiplexed TS signal received by the TSL receiver 21 is sent as it is to the video signal extraction unit (not shown), and the original video data (also audio) is taken out for broadcasting. Is done.

Hereinafter, the flow of signals and data (hereinafter referred to as data and the like) will be described in detail focusing on TCP data.
(1) First, the flow of data and the like on the relay base station 3 side will be described in detail based on FIG. 3, FIG. 4, and FIG.

  That is, the UDP data in the operating state at the time of reception by the FPU receiver 11 and the TCP data that is the status information of the FPU receiver 11 are sent together to the data multiplexing device 12, and are distributed to the TCP data and the UDP data by the distribution unit 31. It is done. This UDP data is sent to the TS converter 32 and is TS-encapsulated to be a UDP / TS signal. Then, the UDP / TS signal is sent to the multiplexing unit 33 and multiplexed with the video TS signal from the FPU receiver 11. The multiplexed multiple TS signal is transmitted from the TSL transmitter 13 and received by the TSL receiver 21 of the broadcasting station 4. The received multiplexed TS signal is sent to the data separation device 22, and after the UDP / TS signal is taken out by the separation unit 41, it is non-TS encapsulated. The non-TS encapsulated UDP data is sent to the FPU control device 23, and the operation status of the relay base station 3 side device, at least the FPU receiver 11, is grasped.

  By the way, as shown in FIG. 3 and FIG. 7, the TCP data that is the status information of the operation of the FPU receiver 11 sent from the FPU receiver 11 to the FPU control device 23 via the base station side router 15 is the first one. The MAC address set from the FPU receiver 11 to the data multiplexer 12 is converted (replaced) from the data multiplexer 12 to the base station side router 15 by the address converter 34, and the FPU receiver 11 The IP address set for the FPU control device 23 is converted from the data multiplexing device 12 to the data separation device 22 and sent to the data separation device 22 via the base station side router 15 and the broadcast station side router 25. .

  On the other hand, TCP data which is command information for controlling the FPU receiver 11 sent from the FPU control device 23 via the TCP / IP line 6 is sent to the data multiplexing device 12 via the base station side router 15.

In the data multiplexer 12, as shown in FIGS. 4 and 7, the TCP data enters the second address conversion unit 35, where it is set from the base station side router 15 to the data multiplexer 12 and is set to the MAC address. The address is converted from the data multiplexer 12 to the FPU receiver 11, and the IP address set from the data separator 22 to the data multiplexer 12 is converted from the FPU controller 23 to the FPU receiver 11. And sent to the FPU receiver 11 to optimize the reception state in the receiver.
(2) Next, the flow of data and the like on the broadcasting station side will be described in detail based on FIG. 5, FIG. 6, and FIG.

  That is, TCP data that is command information of the FPU receiver 11 on the relay base station 3 side is output from the FPU control device 23, and this TCP data enters the third address conversion unit 42, where FIG. 5 and FIG. 8, the MAC address set from the FPU control device 23 to the data separation device 22 is converted from the data separation device 22 to the broadcast station side router 25, and the FPU control device 23 sends the FPU receiver. 11 is converted from the data separator 22 to the data multiplexer 12. As described above, this TCP data enters the data multiplexing device 12, and the second address conversion unit 35 converts the MAC address from the data multiplexing device 12 to the FPU receiver 11, and the IP address also includes the FPU. It is converted from the control device 23 to the FPU receiver 11 and sent to the FPU receiver 11.

  On the other hand, TCP data, which is status information of a predetermined device, sent from the base station side router 15 to the broadcast station side router 25 enters the fourth address conversion unit 43. Here, as shown in FIG. 6 and FIG. The MAC address set from the station side router 25 to the data separator 22 is converted from the data separator 22 to the FPU controller 23 and set from the data multiplexer 12 to the data separator 22. The IP address is converted from the FPU receiver 11 to the FPU controller 23 and finally sent to the FPU controller 23.

  According to the above-described configuration, when the video TS signal from the FPU transmitter is transmitted to the broadcast station 4 via the relay base station 3, the operation state regarding the predetermined device on the relay base station 3 side, for example, at least the FPU receiver 11 is set. The UDP data shown is TS-encapsulated by the data multiplexing device 21 to obtain a UDP / TS signal, and the UDP / TS signal and the video TS signal are multiplexed by the multiplexing unit 33 and sent from the relay base station 3 to the broadcasting station 4. As described above, UDP data having a large amount of data that cannot be sent via the TCP / IP line 6 can also be sent together with the video TS signal. Therefore, a predetermined device on the relay base station 3 side, that is, at least the FPU receiver 11 Since the operation state can be sufficiently grasped, it is possible to transmit high-quality video / audio data.

  Further, although the data multiplexing device 12 on the relay base station 3 side and the data separation device 22 on the broadcast station 4 side are interposed, the source address and destination address of the TCP data that is command information and status information are as follows: Since each address conversion unit performs conversion, TCP data can be exchanged without any problem.

  In particular, since the support information indicating the operation state output from the FPU receiver is converted into a UDP frame and converted into UDP data, at least data passed between the FPU receiver and the receiver on the broadcasting station side is UDP. Since the data is converted into a TS frame, only one type of handling target is required for each device. Compared to the case where the support information is directly converted into a TS frame as in the prior art, for example, the broadcasting station side Since it is not necessary to be able to cope with various formats, it is very economical.

  By the way, as shown in FIG. 1, the FPU reception support information transmission device 7 is composed of the data multiplexing device 12, the base station side router 15, the data separation device 22, and the broadcast station side router 25 described above.
