BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording and reproducing apparatus for recording and reproducing information signals, and more particularly to a recording and reproducing apparatus for simultaneously and independently recording and reproducing information signals.

[0002]

2. Description of the Related Art Conventionally, in a recording / reproducing apparatus used for a broadcasting station or a general home, for example, a VTR (Video Ta
There is a device for recording and reproducing information signals using a tape as a recording medium, such as a pe recorder. In particular, in a broadcasting station, when using this kind of recording / reproducing apparatus for program editing or the like, it is necessary to confirm the quality of the recorded information signal. The quality is checked by setting a recorded tape cassette.

However, in the recording / reproducing apparatus using a tape as a recording medium as described above, recording and reproduction cannot be simultaneously performed independently, so that the quality of an information signal being recorded cannot be confirmed. There is a problem. In addition, there is also a problem in that it is not possible to record the surrounding situation during the reproduction while confirming the reproduction of the recorded information signal.

[0004]

As described above, in the conventional recording / reproducing apparatus, recording and reproduction cannot be performed simultaneously and independently, so that the quality of the information signal being recorded cannot be confirmed. There is a problem that. Another problem is that it is not possible to record the surrounding situation during the reproduction while confirming the reproduction of the recorded information signal.

It is an object of the present invention to provide a recording / reproducing apparatus which can perform recording and reproduction simultaneously and independently with one apparatus.

[0006]

According to this structure, a memory capable of reading and writing information signals is used as a recording medium, and at the time of recording, the memory is accessed and an information signal containing any one of the acquired video, audio and data is obtained. Is written in the memory, and at the time of reproduction, the memory is accessed separately from the time of recording, and the information signal written in the memory is read.

Therefore, the recording and reproduction of the information signal in the memory can be simultaneously and independently performed by one device, and it is possible to flexibly cope with an emergency broadcast.

In the above-mentioned configuration, a control process is further performed on the reading means so as to read out the information signals in the order of writing the information signals from the memory after a predetermined time from the start of the writing of the information signals to the memory by the writing means.

According to this configuration, at the time of reproduction, the control process is executed such that the information signals are read out in the order in which they were written from the memory after a predetermined time from the start of writing the information signals to the memory. The control process is executed so that the information signal is written to the storage location of the memory where the reading has not been performed.

Therefore, it is possible to check the quality of the information signal being recorded in real time, and it is also possible to record the surrounding situation during the reproduction while confirming the reproduction of the information signal.

In the above configuration, the display further includes a display, and display control means for displaying the information signal read from the memory by the reading means on the display, so that the user can view the display.

A second information transfer unit, wherein the reading unit transfers an information signal between the third connection unit connected to the external device and the external device connected by the third connection unit. And information transfer means.

According to this configuration, since the main line output which does not pass through the memory is provided separately from the reproduction output from the memory, the broadcast and the program editing can be performed by one common apparatus. It is possible to perform editing simultaneously with reproduction output during broadcasting on a system. For this reason, the whole system is highly reliable and inexpensive.

The reading means selectively transmits the information signal read from the memory or the information signal transferred by the third information transfer means to an external device connected by the display control means or the third connection means. For example, if you want to check the content and quality of an information signal being broadcast on the main line, you can transfer it to a display to display the information signal being broadcast. The information signal read from the memory can be provided even during system maintenance or occurrence of a failure.
