Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention enables the calling subscriber's business to be displayed on the TV screen of the calling subscriber even when the calling subscriber is in a telephone conversation state using a video telephone. The present invention relates to a system for transmitting business conditions using a video telephone, in which the business conditions of a calling subscriber can be transmitted more reliably by displaying the business conditions on the screen.

[Prior Art] Techniques for transmitting business matters from a calling subscriber when the called subscriber is in a busy state include, for example, an answering machine described in Japanese Patent Laid-Open No. 1-135256. A combination of a message recording function and a call waiting service function on a telephone is known. In this case, if the called subscriber receives a call from another third party while the called subscriber is talking with a third party, the call signal from the call waiting from the exchange will be automatically answered. In response to this, the answering machine sends a message to the new third party to inform that the called subscriber is currently on the line and to check whether there is a message for the called subscriber. It has become so. If a message is sent from a third party in response to this message, this message is automatically recorded on the answering machine installed on the receiving subscriber's side.

[Problem to be Solved by the Invention] However, the method according to the above-mentioned publication is somewhat effective since it is possible to record a message from a new third party without interfering with the telephone conversation with the third party. , the content of the message is known for the first time when the message is played back after the call ends. That is, not only can the user not immediately learn about new business from a third party during a call, but the user also has the problem of forgetting to play back the message after the call ends. In addition to this, since the message content is only aurally discernable, it follows that if the reproduction conditions are not good, the message content cannot be recognized by the called subscriber.

It is an object of the present invention to provide a video telephone set installed on the receiving subscriber side, and when the called party receives a call from a new third party while the called party is talking on the video telephone, the third party immediately receives a call from the third party. To provide a method for transmitting business matters using a video telephone, which allows a called subscriber to visually recognize a message from a subscriber.

[Means for solving the problem] The above purpose is to prevent calls from the calling subscriber when the calling subscriber calls the called subscriber and there is an indication that the called subscriber is busy. Based on the television screen interruption request to the telephone exchange, a television screen bus to the incoming subscriber is drawn separately from the voice bus, and a television screen showing the message from the calling subscriber is placed on the bus. This is achieved by causing the television screen to be displayed as a multi-window display screen on the television screen of the called subscriber.

[Operation] When the calling subscriber calls a called subscriber who is already in a busy state, the telephone exchange means displays to the calling subscriber that the called subscriber is busy. Based on this display, if necessary, the originating subscriber sends a television screen interrupt request to the telephone exchange means. When a TV screen interrupt request is received, the telephone exchange means connects only the TV screen bus to the called subscriber separately from the audio bus, and
If this bus is made to display the TV screen as the contents of the message from the calling subscriber, the TV screen will be displayed as a multi-window display screen on the TV screen of the receiving subscriber's video phone. Therefore, from the display screen, the receiving subscriber who is in the conversation state can immediately visually recognize the content of the message, that is, the content of the business from the calling subscriber. If the receiving subscriber confirms the contents of the television screen from the calling subscriber and requests the telephone exchange means to release the television screen interruption, the telephone exchange means stops interrupting the television screen to the bus for the called subscriber. As a result, the television screen of the called subscriber will be restored to its original state.

[Example] The present invention will be explained below with reference to FIGS. 1 and 2.

First, the relay system according to the present invention will be explained. FIG. 2 shows an example of the relay system. l5DN
A plurality of subscribers 1 to 3 are installed in the telephone exchange means 4, which are equipped with video telephones.
Using 2B+D, which is the basic interface of
The other B channel can be used to talk to the other party.

Now, the telephone exchange means 4 according to the present invention is provided with a multi-screen connection/opening means 5, and under the control of this means 5, a new call to a called subscriber who is in a busy state is transferred to the telephone exchange. 4, the TV screen from the calling subscriber side is displayed in a multi-window on the TV screen of the terminating subscriber side, provided that a specific operation is performed on the calling subscriber side using the remaining D channels. It looks like this.

That is, here, for example, the telephone exchange means 4 between the subscribers 1.2
Assuming that a call is being made via a telephone, in this state the TV screen will be transmitted to the other party, and each subscriber 1 and 2 will be able to see the TV screen from the other party on their own TV screen. You can talk to the other party while displaying the message above. In this situation,
When subscriber 3 dials the phone number of subscriber 2,
The telephone exchange means 4 attempts to call subscriber 2, but since subscriber 2 as the incoming subscriber is currently in a busy state, subscriber 3 as the originating subscriber is notified that the call is busy. The sound is transmitted from the telephone exchange means 4.

This allows subscriber 3 to know that subscriber 2 is in a busy state. When such a situation occurs, subscriber 3 would normally call subscriber 2 again at a later time at a suitable time. However, because
If the subscriber 3 sends a TV screen interrupt request to the telephone exchange means 4 by operating a specific key or dialing a special number while the busy tone is being notified, the telephone exchange means 4
Then, by activating the multi-screen connection function in the multi-screen connection/opening means 5, the TV screen from the subscriber 3 side captured by the TV camera is inserted into the TV screen from the subscriber 1 who is already in the busy state. Subscriber 2
It is designed to be displayed in multiple windows on the side TV screen. FIG. 1 shows the television screen on the subscriber 2 side at that time. As shown in the figure, most of the television screen is occupied by the television screen 2a from subscriber 1, but it can be seen that a portion is displayed as the television screen 2b from subscriber 3. Even if the TV screen 2b from subscriber 3 is displayed on the TV screen of subscriber 2 by the multi-screen connection/opening means 5, it will not affect the call between subscribers 1 and 2 in any way. There is no such thing as this. In this manner, the subscriber 2 can immediately visually recognize the request from the subscriber 3 from the television screen 2b displayed on the television screen.

Now, after subscriber 2 recognizes and confirms the request from subscriber 3, he will send a request to release the TV screen interrupt to the telephone exchange means 4 by operating a specific key, etc. Based on the release request, the telephone exchange means 4 activates the multi-screen release function in the multi-screen connection/release means 5, and as a result, the television screen on the subscriber 2 side is restored to its original state.

[Effects of the Invention] As explained above, in the case of the present invention, when a video phone is installed on the receiving subscriber side, an incoming call from a new third party is received while the called party is talking on the video phone. If there is a message from the third party, the receiving subscriber will immediately be able to visually recognize the message from the third party.
