Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video / audio transmitting / receiving apparatus for transmitting / receiving video and audio.

[0002]

2. Description of the Related Art FIG. 3 is a perspective view of a conventional still picture television phone, wherein 1 is a display unit for displaying a still image of the other party, 2 is a telephone unit formed integrally with the display unit 1,
Reference numeral 2a is its handset, 3 is a built-in camera unit, and 5 is a telephone line connected via a terminal 4. In addition, the other side is connected to the still image videophone via the telephone line 5.

Next, the operation will be described. Camera section 3
The image taken by is transmitted to the destination side via the telephone line 5, and is displayed as a still image on the display unit on the destination side. On the other hand, voice is transmitted from the handset 2a of the telephone unit 2 to the other party through the telephone line 5 and is output from the other party. On the other hand, on the contrary, video and audio are output to the other side from the other side through the telephone line 5. In this way, the voice and the image by the conversation of both parties are transmitted and received.

[0004]

As described above, conventionally, in order to transmit and receive video and audio between two points apart from each other,
Both of them required a dedicated still image videophone, and no longer needed an existing telephone, which made them expensive.

The present invention has been made to solve the above problems, and an existing telephone can be used as it is, and an image and voice can be inexpensively transmitted and received between two distant points. The purpose is to obtain a transmitting and receiving device.

[0006]

A video / audio transmitting / receiving apparatus according to the present invention has a built-in telephone line repeater, is connected to a telephone line, and is input from the telephone line via the telephone line repeater. A television that outputs a signal, a telephone that is connected to the television and that transmits and receives an audio signal through a telephone line repeater and a telephone line, and that is connected to the television.
A video camera for transmitting a video signal via a telephone line repeater and a telephone line is provided.

[0007]

According to the present invention, the video signal is projected from the video camera to the television of the other side through the telephone line repeater and the telephone line, and the video signal from the other side is transmitted to the other side through the telephone line and its repeater. Is projected on the TV.
The voice signal is output from the telephone to the telephone on the other side through the repeater and the telephone line, and the voice signal from the destination is output to the telephone on the other side through the telephone line and the repeater.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows the structure of a video and audio transmission / reception apparatus according to this embodiment, and 6 is a television with a built-in telephone line repeater, which has a built-in telephone line repeater. A telephone line 5 is connected to the television 6 through a terminal 7, a telephone 9 is connected through a terminal 8, and a video camera 11 is further connected through a terminal 10.

In the above structure, the voice input from the telephone 9 and the video input from the video camera 11 are input to the television 6 via the terminals 8 and 10, respectively, and the terminals are input via the built-in telephone line repeater. 7 is sent to the other side through the telephone line 5, the image is projected by the television with a built-in telephone line repeater on the other side, and the voice is output from the telephone. Audio and video signals from the other side are input to the television 6 from the telephone line 5 via the terminal 7, the video signal is projected to the television 6 via the built-in telephone line repeater, and the voice signal is the telephone signal. It is output from 9.

FIG. 2 shows a reference example of the present invention, in which the electrical connection is substantially the same as that of the above-mentioned embodiment, (a) shows the near side, and (b) shows the forward side. 12 and 18 are telephone line repeaters, 13 and 19 are ordinary televisions, 14 to 17 and 22 to 2
5 is a terminal, 20 is a telephone, and 21 is a video camera.

The electrical connection of this reference example is substantially the same as that of the above example, but the audio signal and the video signal from this side are input from the telephone 9 and the video camera 11, and the repeater 12 and the telephone line 5 are used. Is input to the repeater 18 on the destination side, the voice signal is output from the telephone 20, and the video signal is displayed on the television 19. The audio signal and the video signal from the other side are transmitted through the opposite paths.

[0012]

As described above, according to the present invention, the transmission and reception of the audio signal and the video signal between two points which are apart from each other can be performed at a low cost by using the existing telephone and video camera.
