Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for relaying a television image taken by a television photographing device mounted on a transportation means such as a vehicle, a ship and an aircraft.

[0002]

2. Description of the Related Art A vehicle, such as a television interview vehicle, is used for taking a live television image of an object whose location is constantly changing, such as a marathon event or a relay race event. Similarly,
A ship is used for taking live television images of the sea or underwater, and an aircraft such as an airplane, helicopter, or airship is used for taking live television images of the sky.
In order to relay the television images shot by the television shooting equipment mounted on these transportation means,
A so-called two-stage relay is performed in which video waves are transmitted from moving transportation means to a ground facility installed in a building or a helicopter in the sky, and the ground facility or helicopter receiving the video waves relays and transmits to a base station. ing.

A conventional two-stage relay system using a television coverage vehicle which is the most general two-stage relay system will be described with reference to FIG. In the figure, 1 is a television interview vehicle, 2 is a relay helicopter, 3 is a building, and 4 is a base station connected to a broadcasting station. The television news gathering vehicle 1 moves with a moving object to be photographed, the helicopter 2 flies several hundred meters above the television news gathering vehicle 1 several hundred meters above the sky, and the television news gathering vehicle 1 and the base station 4 perform several kilometers to several tens of meters. Km away.

The television coverage vehicle 1 is equipped with television photographing equipment, image adjusting equipment, and image radio wave transmitting equipment for performing work using these equipment.
Further, a beam antenna 5 such as a helical antenna for transmitting image radio waves to the helicopter 2 in the sky is mounted on the roof. The helicopter 2 has a beam antenna 6 such as a helical antenna for receiving the image radio wave transmitted from the television coverage vehicle 1 and a beam antenna 7 such as a helical antenna for retransmitting the received image radio wave to the base station 4. It is installed. The ground equipment 3 has a beam antenna 8 such as a parabolic antenna for receiving the image radio waves transmitted from the television coverage vehicle 1 and a beam antenna 9 such as a parabolic antenna for retransmitting the received image radio waves to the base station 4. Is attached. The base station 4 is provided with a beam antenna 10 such as a parabolic antenna for receiving the image radio waves retransmitted from the helicopter 2 or the ground facility 3. A beam antenna 10 such as a parabolic antenna for communication is provided.

Since image radio waves require large signal strength,
A UHF band or SHF band radio wave formed into a narrow beam by a helical antenna or a parabolic antenna is used. Therefore, the helicopter that relays the image radio wave must receive the thin beam radio wave surely and surely transmit the received signal to the next relay point, so that the television coverage vehicle and the base station can always fly at the same time. Must.

Regarding the relationship between the base station and the helicopter, there have been developed a system for clearly indicating an area that can be seen from the base station on a map or a system for constantly directing the transmission antenna of the helicopter to the base station. This system controls the azimuth detector consisting of a geomagnetic sensor and an azimuth gyro, the pitching and rolling angle detector consisting of a vertical gyro, and the helicopter transmission antenna always pointing to the base station based on the data of these detectors. is doing.

Even when such a system is used, in order to complete the relay, the helicopter is still in a range in which the television coverage vehicle and the base station can simultaneously see, especially from a television coverage vehicle which is a mobile body. It is necessary to fly with good reception of radio waves.

As described above, the helicopter flies several hundred meters above the television coverage vehicle for several hundred meters, but it is easy to see the helicopter from the television coverage vehicle. The beam antenna that transmits video radio waves from the news gathering vehicle is manually tracked in the direction of the helicopter by the operator on the roof of the television news gathering vehicle. However, it is difficult to see a television interview vehicle on the ground far from a helicopter in the sky,
It is virtually impossible to manually track the receiving antenna attached to the helicopter in the direction of the television coverage vehicle. Further, since the positions of the television coverage vehicle and the helicopter are constantly changing, it is very difficult to automatically track the receiving antenna attached to the helicopter.

In addition, the traveling speed of the television coverage vehicle that is shooting a marathon or the like and the flying speed of the helicopter are different, and the helicopter must be operated to some extent. The positional relationship may be lost and the reception of the television video signal may be incomplete and the relay may become unstable.

[0010] Further, the helicopter used for television relay may not only relay the image captured by the television interview vehicle, but may also capture the image from the sky. In that case, it is necessary to move to the sky above the shooting site and return to a predetermined position to relay the image radio wave after the end of the image capturing so that the image radio wave can be relayed. The positional relationship is lost, and the reception of television image radio waves is incomplete and the relay becomes unstable.

By the way, the image radio wave from the television interview vehicle is radiated as a narrow beam by the beam antenna, and the beam has a certain spread.
Not strict. In addition, the tracking of the beam antenna of the television coverage vehicle is performed manually by the operator visually recognizing the helicopter. Therefore, the beam antenna for reception attached to the helicopter should be oriented in the approximate direction required from the positional relationship with the television interview vehicle, or the direction of the beam antenna should be fixed and flight within the range in which video waves can be stably received. By doing so, the helicopter relays the image radio waves.

In competitions such as marathons, the runners to be photographed are often divided into several groups, and a plurality of television coverage vehicles may be used to photograph these groups. Even in such a case, one helicopter relays the video radio waves from the television coverage vehicle to the base station, and therefore the helicopter that relays the video radio waves is the video from multiple television coverage vehicles. You must fly with the ability to receive radio waves. However, it is very difficult to fly in a state where image radio waves from a plurality of television coverage cars are always received.

Further, in a television relay using a plurality of television reporting vehicles and a helicopter as described above, it is necessary to control the whole by grasping the positional relationship between them. Since this positional relationship is grasped by verbal reports from each television relay vehicle and helicopter, the content is not only inaccurate but also not real-time. Therefore, the control becomes inaccurate, which may cause confusion in television program production.

By the way, recently, a GPS (Grobal Positioning System), which is a positioning system using artificial satellites, is rapidly becoming popular as a navigation system for ships or automobiles. This GPS is a system that measures the distance from each artificial satellite from the time difference of arrival of radio waves from a plurality of artificial satellites equipped with atomic clocks, and measures the position on the earth from the measurement results. C / A (Coarce) The error in the case of coarse precision, called a code, is 10
0m, which is called a P (Precision) code and has an error of 16m in the case of high accuracy which is not disclosed. In addition, a fixed receiving station whose accurate position is known receives the C / A code to detect an error, broadcasts the error, and based on this error, C / A
There is also a system called differential GPS that measures the exact position of the mobile station that received the A code.

[0015]

SUMMARY OF THE INVENTION The present invention has been made based on such a situation, and in order to stabilize the relay of a television image signal by a helicopter from a television coverage vehicle or ground equipment, a television coverage vehicle and The object is to make it possible to accurately control the flight position of a helicopter. Therefore, in the present invention, a GPS receiver is mounted on the television coverage vehicle and the helicopter, and the positions of the television coverage vehicle and the relay helicopter are displayed based on the positional relationship measured by these GPS receivers.
