Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a video floppy device that records and reproduces a video signal using a floppy disk.

[0002]

[Prior art]

 Conventionally, a video tape recorder has been widely used as a device for recording and reproducing a video signal, and a video tape is used as a recording medium. Ordinary floppy disks are not used because it is considered that they cannot be used for recording video signals because their storage capacity is too small.

[0003]

[Problems to be solved by the device]

 However, when recording and playing back a video tape with a video tape recorder, the video tape is long and the video signal is recorded sequentially from the end of the tape. The problem was that random access took a long time, as it had to send the information to find the desired location. There is also a problem that the tape is damaged and stretched and deteriorated due to repeated feeding and rewinding of the video tape, and its life is shortened. Furthermore, there is a problem that the video tape cassette is bulky because it is handled as a unit, and space is required for storing it.

The present invention has been made in view of the above-mentioned conventional problems. Random access of recorded video information can be performed in a short time, the life of the video can be extended, and the video can be stored in a storage medium. It is an object to provide a floppy device.

[0005]

[Means for Solving the Problems]

 The video floppy device of the present invention is such that a video signal processing section for converting an input video signal into a signal for internal processing and an internal processing signal processed by the video signal processing section are stored in a predetermined address of a floppy disk. The floppy disk memory processing unit that stores the data, the floppy disk drive unit that drives the floppy disk, and the internal processing signal that is stored at the specified address of the floppy disk installed in this floppy disk drive are read out and converted into a video signal. It is provided with a floppy disk video signal reproducing section for re-converting and outputting.

[0006]

[Action]

 In the video floppy device of the present invention, a video signal from an external video camera or other video signal output means is input, the video signal processing unit converts it into a signal for internal processing, and the floppy disk storage processing unit performs floppy disk storage. Store at a specified address on the disc.

At the time of reproduction, the floppy disk video signal reproducing section reads out the address recording information designated by the floppy disk video signal reproducing section, converts it to a video signal, and reproduces it from the outside. Output to.

Therefore, by connecting this video floppy device to a video camera, a CRT monitor or other monitors, it becomes possible to record a video signal on a floppy disk and reproduce it.

【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a functional block diagram of an embodiment of the present invention, and FIGS. 2 and 3 show the appearance thereof. First, as shown in FIG. 1, the video floppy device of this embodiment is a video signal processing unit 1 for converting a video signal input from an external video camera, another video reproducing device or the like into a signal for internal processing. , A floppy disk storage processing unit 2 for storing the internal processing signal processed by the video signal processing unit 1 at a predetermined address of the floppy disk, a floppy disk drive unit 3 for driving the floppy disk, and the floppy disk drive unit. The floppy disk video signal reproducing section 4 reads the internal processing signal stored in a predetermined address of the floppy disk, reconverts it into a video signal and outputs it. The FD is a floppy disk.

Then, by outputting the video signal output from the floppy disk video signal reproducing section 4 to a CRT monitor or a liquid crystal monitor such as a television receiver, the video information recorded on the floppy disk FD is imaged. It can be played and shown as.

Next, the hardware of the video floppy device of this embodiment will be described. As shown in FIG. 2, the device is incorporated in one case like a video tape recorder, and an operation unit is provided on the front surface. A power switch 11, a video recording switch 12, a video playback switch 13, a stop switch 14, a random access setting switch 15 and the like are provided as a built-in floppy disk drive device for incorporating a floppy disk FD. A floppy disk insertion slot 17 is also provided.

Further, as shown in FIG. 3, on the rear surface of the device case, input terminals 18 and 19 for inputting a video signal and an audio signal from a video camera or another video device, and a floppy disk video reproduction processing unit 4 are provided. Output terminals 20 and 21 are provided for outputting the video signal and the audio signal which have been subjected to the reproduction processing in 1.

Next, the operation of the video floppy device having the above configuration will be described.

When video-recording on the floppy disk 16, the video output and audio output of the video camera and other video equipment are input to input video signals from the video input terminal 18 and the audio input terminal, respectively. 19, and the floppy disk 16 is inserted from the floppy disk insertion slot 17 and set in the floppy disk drive unit 3. Then, the video recording switch 12 is turned on.

As a result, the video signal from the outside is converted into the internal processing signal by the video signal processing unit 1, and the floppy disk storage processing unit 2 sequentially records the video information in the empty area of the floppy disk FD.

Next, when reproducing, by turning on the video reproducing switch 13, the floppy disk video signal reproducing section 4 accesses a predetermined location of the floppy disk FD to read the recorded information, and the internal processing is performed. The signal is converted back to a video signal and output as a video playback signal to the outside.

Therefore, by connecting the video input terminals of the television receiver and other monitors to the output terminals 20 and 21 of the video floppy device, the video signal and the audio signal can be reproduced.

If the information recorded on the floppy disk is to be reproduced at random, the random access switch 15 can be operated to instantaneously access and reproduce the video information at a predetermined address. Like

The present invention is not limited to the above-described embodiment, and in particular, by using the floppy disk and the recording / reproducing system of the perpendicular magnetization recording system capable of high density recording, Can be increased. In addition, the recording method is not the one that is stored in the track as in the case of normal floppy disk recording, but the spiral recording method that is used in the conventional disk record, so that smooth recording and playback of video signals can be performed. Becomes

[0021]

[Effect of device]

 As described above, according to the present invention, a video signal from an external video camera or other video signal output means is input, the video signal processing unit converts the signal to an internal processing signal, and the floppy disk storage processing is performed. The floppy disk video signal playback section reads the recorded information at the specified address for the floppy disk installed in the floppy disk drive section when the data is stored in the floppy disk drive section. , The video signal is converted and output to the outside, so by connecting this video floppy device to a video camera, CRT monitor or other monitor, the video signal can be recorded on the floppy disk and played back. It is now possible to use a long video recorder like a conventional video tape recorder. Since Otape is not used as a recording medium, quick random access is possible, the recording medium does not easily deteriorate, and video information can be recorded stably over a long period of time. The medium is compact and has the advantage of being inexpensive.
