DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a warning information notification system for superimposing a text message on a control terminal in accordance with the type of a voice message sent from an image exchange.

[0002]

2. Description of the Related Art Conventionally, in order to send warning information such as five minutes before the end of a reservation from an image exchange, as shown in FIG. 4, a talkie trunk RAM capable of recording a message in accordance with the type of warning information and circuit exchange are performed. It has a switch TSW, a subscriber circuit LC that interfaces with the control terminal CT, and a processing device CPU that performs program control.

When warning information must be sent to a control terminal in a call control process by a program, by closing a path of a switch TSW according to the type of warning information,
The recorded voice message can be transmitted to the control terminal CT, and the image terminal user recognizes the content of the warning (for example, 5 minutes before the end of the reservation) by listening to the recorded message.

[0004]

In the above-mentioned conventional warning information notifying method, the contents of the warning are notified to the user of the image terminal by a voice message not from the audio unit of the image terminal but from the control terminal, and the user is aware of the contents of the warning. Due to this method, when the image terminal is used while the image terminal is used, the warning information is hardly noticed. For this reason, if the user cannot recognize this warning, there is a problem that the video and audio of the image terminal in use are suddenly cut off at the reservation end time, giving the user an unpleasant impression.

The present invention has been made in view of such a situation, and provides an apparatus in which warning information is easily noticed by an operator.

[0006]

SUMMARY OF THE INVENTION In order to solve such a problem, the present invention provides a plurality of superimpose circuits for storing warning information to be warned by a video signal in the form of a video signal, and a superimposing circuit provided from an exchange. And a selection circuit for detecting a special sound and selecting a necessary superimpose circuit, and a mixing circuit for mixing the warning information selected by the selection circuit with the video signal.

[0007]

[Function] A special sound supplied from an exchange is detected by a detection circuit, a necessary superimpose circuit is selected according to the detection result, and a warning signal output from the superimpose circuit is a video signal by a mixing circuit. And output. Therefore, the operator can recognize the warning signal on the screen.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the present invention.
In the figure, VSW is a video signal switch for video signals, ASW is an audio switch for audio signals, TSW is a switch for performing circuit exchange, CPU is a processing device for performing program control of these switches, and RAM # 1 and RAM # 2 (implemented). # 1 in the example
And # 2, but the actual number of RAMs is necessary for the number of necessary messages). A different type of warning information message and a talkie trunk capable of recording a special sound that can identify the type of warning information. Subscriber circuits that interface with the control terminal, which is the main unit, are the main functional blocks constituting the image exchange.

Further, CT is a control terminal for instructing the image exchange of various control information (call setting request, call response, etc.) from the image terminal, TV is a television, CAM is a television camera, MIC is a microphone, and SP is a speaker. These devices constitute an image terminal.

FIG. 2 shows an example of the structure of a message recorded in the RAMs # 1 and # 2. In the figure, SIT is a special sound indicating the type of warning information, and the message is a recording of the contents of the warning. .

FIG. 3 shows functional blocks of the control terminal. In the figure, CTL denotes an operation panel and a control circuit for giving a call setting instruction to the image exchange, SIP # 1 and SIP # 2 denote superimpose circuits storing video information to be superimposed, and SEL denotes DET. The DET identifies the type of special sound sent from the image exchange, instructs the SEL of the identification result, and superimposes the MIX on the MIX. The detection circuit MIX instructs the start of the pause, and MIX superimposes information to be superimposed selected by SEL according to the instruction of DET on the video signal sent from the image exchange, and then converts the video signal into an image. This is a mixing circuit to send to the terminal.

When sending warning information (for example, 5 minutes before the end of a reservation) from the image exchange to the control terminal, first, the image exchange selects a trunk RAM corresponding to the warning information and communicates with the subscriber circuit LC via the switch TSW. The connection is established, and a message of warning information is sent to the subscriber circuit CT together with the special sound. In the subscriber circuit CT, the special sound sent from the image exchange is detected by the detection circuit DET, and the special sound type is selected by the selection circuit S.
At the same time, the EL is instructed to select the speakers SP # 1 and SP # 2, and at the same time, the mixing circuit MIX is instructed to start superimposing.

In the mixing circuit MIX, information to be superimposed selected by the selection circuit SEL is superimposed on the video signal from the image exchange and transmitted to the image terminal. As a result, the warning signal is superimposed on the screen operated by the operator as an image. Therefore, even if the warning by voice is not noticed, a necessary warning can be recognized by the warning displayed on the screen.

[0014]

As described above, according to the present invention, the warning message from the image exchange is sent by voice, but the text message is superimposed by the video information of the image terminal. This has the effect that the user can visually recognize the warning, and can eliminate the disadvantage of failing to recognize the warning as in the related art.
