Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image recording / reproducing apparatus capable of recording / reproducing and editing video signals.

[0002]

2. Description of the Related Art At present, as an image recording / reproducing apparatus for recording / reproducing a video signal, which is widely used in general households,
There is a video tape recorder (hereinafter referred to as a home VTR) that uses a tape-shaped recording medium.

The home VTR has the following basic structure. That is, an input unit for inputting a video signal, a recording signal processing unit for performing a predetermined signal processing on the input video signal to convert it into a signal suitable for recording and reproduction on a tape-shaped medium, and a magnetic tape on a rotating cylinder. From a recording / reproducing mechanism section for winding and recording and reproducing, a reproduction signal processing section for performing a signal processing on a reproduction signal in the reverse of the recording signal processing section, and an output section for outputting a reproduction video signal to a monitor or the like. Has become. The input video signal includes a television broadcast received by a tuner, a video signal reproduced by another image reproducing device, and the like.

Most conventional VTRs for home use have only a recording / reproducing mechanism for recording / reproducing on / from a magnetic tape. For editing between tapes, two or more VTs are used.
It was necessary to connect R.

[0005]

[Problems to be Solved by the Invention]
Connecting the TRs is not only complicated, but also requires some knowledge about the connection, which cannot be easily performed in a general home. As a method for solving these problems, there are JP-A-63-175248 and JP-A-3-57733.

In Japanese Patent Laid-Open No. 175248/1988, a recording / reproducing mechanism except the tuner, the external signal input section, the recording signal processing section, and the reproducing signal processing section in the basic structure of the domestic VTR described in the section of the prior art. With a structure having two parts, two cassette tapes can be loaded, and dubbing and recording / reproduction for a long time are possible.

Further, in Japanese Utility Model Laid-Open No. 3-57733,
The system has a system control unit connected to two or more recording / reproducing mechanism units, each of which is connected to a timer, and realizes editing dubbing between tapes and recording / reproducing for a long time as described above.

However, in any of the above cases, the recording / reproducing mechanism unit itself is merely a plurality of recording / reproducing mechanism units in the basic structure of the conventional VTR, which are accommodated in the frame of one VTR. It has the exact same structure. Therefore, a mechanical system (that is, a magnetic tape running system, a cassette loading mechanism, a cassette insertion unit, etc.) that substantially determines the size of the VTR is added, and the VTR becomes large.

For example, in order to edit two or more original tapes to make one editing tape, it is necessary to have at least three recording / reproducing mechanism sections, and the apparatus becomes considerably large. Will end up. Further, in any case, there is a problem that it takes a considerable amount of time to perform complicated editing, that is, program editing including cut editing by jumping a tape playback portion, slow playback, high-speed playback, and the like.

In view of the above points, the present invention has an object to provide an image recording / reproducing apparatus which has only a tape recording / reproducing mechanism section and can perform complicated editing more easily and in a shorter time. .

[0011]

According to the present invention, an input section for inputting a signal in a video signal format, an output section for outputting a signal in a video signal format, and a first section suitable for recording and reproducing on a tape-shaped medium are provided.

A reproducing means, a system converting means for mutually converting a video signal format signal, a first signal format signal and a second signal format signal, a tape medium recording / reproducing means and a disk medium recording / reproducing means. This is a configuration including control means for controlling the operation of the method conversion means.

[0012]

According to the present invention, the original tape reproduction signal (that is, the first tape reproduction signal from the tape-shaped medium recording / reproducing means is constituted by the above-mentioned structure.
Signal of the signal format) is converted into a recording signal (that is, a signal of the second signal format) for the disc-shaped medium by the system conversion means, and once recorded in the disc-shaped medium by the disc-shaped medium recording / reproducing unit, The disc reproduction signal (that is, the signal of the second signal format) edited and reproduced according to the control means is converted into a recording signal to the tape (that is, the signal of the first signal format) by the system conversion means, and finally the tape shape is obtained. Since recording is performed on the exchanged tape in the medium recording / reproducing means, it is possible to realize an image recording / reproducing apparatus having only the tape recording / reproducing mechanism section and capable of easily performing complicated editing in a short time.
