Abstract

PURPOSE:To identify a transmitter or to grasp the transmission state by obtaining a message signal from a reception signal, a signal relating to the attribute or a signal recognizing the transmission state and displaying it on a receiving picture superimposingly. CONSTITUTION:The information of the attribute and message set by a message setting means 101 and an attribute setting means 102 is sent from the sender side to the receiver side as a microwave via a modulation circuit 105 as one of voice signal to be sent by an information transmission means 103 as a microwave. An identification signal at the sender side is displayed while being superimposed on a received video signal via a demodulation circuit 106, an information decoding means 107 and a character multiplex means 108 at the receiver side. As a result, the attribute and message of the transmitter are read as character information and the transmission source is easily specified even in the presence of plural transmission sources.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a portable microwave repeater (commonly known as FPU unit).
The present invention relates to a device that transmits and displays a signal for identifying the device or a signal representing the status of the device.

[Summary of the invention]

The present invention solves the problem of FPU device identification, which was insufficient in the prior art, by converting a message signal inputted from a keyboard, etc., and a signal related to pre-registered attributes into a modem signal, or transmitting, which was not possible in the prior art. The signal representing the detected state is converted into a modem signal so that the state of the receiver can be monitored at the receiving end, and the signal is applied to an unused audio channel of the transmitter, and microwave transmission is performed in the same way as other video and audio signals. The receiver obtains message signals, attribute signals, and signals indicating the transmission status from the received and demodulated modem signal, and superimposes and displays them on the received image to identify the transmitter or grasp the transmission status. This allows an identification signal or a signal representing the transmission status to be transmitted from the transmitting side to the receiving side without affecting the transmission of video and audio signals on the nine lines.

[Conventional technology]

Conventionally, in FPU devices, there has been no means for specifying the attributes of the sending side on the receiving side. As something similar to this method,
In order to set up the transmission line, station name characters were sometimes superimposed on the test video signal (color par signal) sent by the transmitter, but this was done to avoid overlapping lines between the own station and other stations when setting up the line. It was used to identify waste.

Conventionally, since the attributes of the transmitting device cannot be identified on the receiving side, especially when trying to produce a multi-relay program where multiple transmission sources exist,9 program producers have to identify multiple received images. , or a specific source must be estimated and determined from the received audio content, which is a compromise when producing programs that aim to be accurate and quick.

Conventionally, as a means of checking the status of the device, the display of output power, video/audio level, etc. using a level meter on the operation panel, alarm lamps that indicate a drop in transmit power, a drop in source pressure, etc. It only had the following functions. These are all displayed on the operation panel, and if the installation location of equipment such as a base station (usually on a transmitting/receiving antenna tower) is far from the monitoring location (usually inside a station building), it may be difficult to manage the equipment. There were many inconveniences.

Furthermore, with the prior art, it was impossible for the receiving side to grasp the status of the transmitting side and to manage the transmitting side unattended, unless there was a means for checking the transmitting status.

[Problem to be solved by the invention]

In the prior art, there was no means for transmitting attributes of a transmitting device (station name, used channel, transmission power, device number, etc.) and messages (sending place name, other notifications). Furthermore, there was no means for displaying detailed information about the device, and no means for transmitting the information about the device.

The present invention solves these drawbacks by newly providing a means for transmitting a signal for identifying the device or a signal representing the state of the device, and transmitting the signal on the receiving side.

It is an object of the present invention to provide a microwave transmitting/receiving device in which a transmission source can be easily identified or the state of the device can be grasped.
