Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote reproducing apparatus used for recording and reproducing, for example, a portable video camera.

[0002]

2. Description of the Related Art In recent years, many types of portable video cameras have been manufactured and sold. In this type of portable video camera, the user of the portable video camera looks into the monitor with one eye to check the screen during image capturing. Therefore, when a person other than the user wants to monitor at the time of recording and reproducing, the portable video camera and the monitor television are connected with a dedicated cable.

[0003]

In the above-mentioned conventional portable video camera, when a person other than the user of the portable video camera records or reproduces data, a dedicated video camera is provided between the portable video camera and the monitor TV. A cable is required, and the work of installing and carrying the cable occurs, which is inconvenient. Also, monitor TVs can only be supported if they have a video input terminal or audio input terminal. Moreover, attaching a cable to the portable video camera impairs portability.

The present invention has been made in view of the above problems and does not require a dedicated cable, and is used for recording or reproducing on a general television having no video input terminal or audio input terminal. It is an object of the present invention to provide a remote playback device that enables monitoring of the.

[0005]

In order to achieve the above-mentioned object, a remote reproduction apparatus according to claim 1 of the present application claims a video signal and an audio signal inside a case body of a television. It is characterized by a built-in transmitter that converts to broadcast waves and sends it, and a video input terminal, audio input terminal, and antenna are provided in appropriate places on the case body.

In this remote reproduction device, when a video camera signal is input to the video input terminal and the audio input terminal, the video signal is internally converted into a television broadcast radio wave and transmitted from the antenna. A television broadcast radio wave transmitted from the antenna can be received by a person other than the user of the video camera with a television receiver at hand and monitored during recording or reproduction.

According to a second aspect of the present invention, there is provided a remote reproduction device according to the first aspect.
In addition to the described remote reproduction device, a power input terminal is provided at an appropriate position on the case body. In this remote playback device, a signal is input from the video camera to the video input terminal and the audio input terminal, and power source power is input to the power source input terminal from the power source output terminal of the video camera. Since the electric power input from the power supply input terminal serves as the power source of the remote reproduction device, the supply of external electric power (for example, a battery) is unnecessary.

According to a third aspect of the present invention, there is provided a remote reproduction device according to the first aspect.
Alternatively, in addition to the remote reproduction device according to the second aspect, an operating body such as a knob is provided at an appropriate position of the case main body. When a large number of remote playback devices are used nearby and one television broadcast wave is used, interference may occur in the video and audio of the monitor television. However, in this remote reproduction device, the frequency of the television broadcast radio wave to be transmitted can be changed by an operating body such as a knob, so that no interference occurs in the video and audio of the monitor television.

[0009]

The present invention will be described in more detail with reference to the following examples. FIG. 1 is an external perspective view of a remote reproduction device according to an embodiment of the present invention. The remote reproduction device of this embodiment is provided on a side of the case body 1, a transmitter 2 for converting a video signal and an audio signal contained in the case body 1 into a television broadcast wave, and transmitting the television broadcast wave. Video signal input terminal 3 and audio signal input terminal 4 also provided on the side
And an antenna 5 provided on the upper part of the case body, a power input terminal 6 provided on a side part of the case body, and a knob 7 provided on the front surface of the case body 1.

The transmitter 2 built in the case body 1 is
Similarly, it is electrically connected to the video input terminal 3, the audio signal input terminal 4, the antenna 5, and the power supply input terminal 6 provided on the case body 1. Further, the knob 7 is mechanically connected to the transmitter 2 built in the case body 2, and the knob 7
When is turned, the constituent parts of the transmitter 2 are interlocked. In addition, the video signal input terminal 3, the audio signal input terminal 4,
The antenna 5, the power input terminal 6, the knob 7 and the like may be installed at appropriate places in the main body case 1 different from the above-mentioned embodiment.

FIG. 2 is a perspective view showing an example of use of the remote playback device of the above embodiment. By connecting the video output terminal 9, the audio output terminal 10, and the power output terminal 11 of the video camera 8 to the video input terminal 3, the audio input terminal 4, and the power input terminal 6 of the remote playback device, a video signal to the remote playback device,
An audio signal is input. In addition, power source power is also supplied.
As a result, the video signal and audio signal of the video camera are converted into television broadcast radio waves and transmitted from the antenna 5. This television broadcast radio wave is a handheld television 1
By receiving at 2, the person other than the camera user can monitor.

If a similar device is used nearby,
Interference may occur in television. in this case,
By turning the knob 7 of the remote playback device, the antenna 1
As a result, the frequency of the television broadcast radio wave transmitted will change, and interference can be avoided. Further, the remote reproducing apparatus of this embodiment is adapted to various video recording / reproducing systems and television broadcasting systems.

[0013]

According to the present invention, the video output and audio output of the video camera are converted into television broadcast radio waves and transmitted, so that the television can be received and monitored by the television at hand without connecting a cable. As a result, even a television having no video input terminal or audio input terminal can be monitored, and since no cable is used, portability is not impaired.

Further, since power is supplied from the video camera, it is not necessary to use an external power source such as a battery. Therefore, the size and weight can be reduced. Also, the trouble of installing a battery or the like is eliminated. Further, interference caused by a similar device or another radio wave source nearby can be avoided by turning the knob of the remote reproduction device to change the frequency of the transmitted television broadcast radio wave.
