  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a block diagram of an information recording / reproducing apparatus according to an embodiment of the present invention. As shown in FIG. 1, the video signal input from the video input 1 is converted into a digital video signal by the decoder 2, compressed by the codec 6 through the multiplexer 3, and temporarily stored in the memory 15. The video signal stored in the memory 15 is recorded in the HDD 17 via an HDD (Hard Disk Drive) interface 16. The video signal recorded in the HDD 17 can be output from the video output 5 and reproduced after passing through the HDD interface 16, the codec 6, the multiplexer 3, and the encoder 4 as necessary. It is also possible to record on a different medium using the DVD drive 11 and the USB interface 12 or transmit to a remote place via the LAN interface 13. The operation in such an information recording / reproducing apparatus is controlled by the CPU 7.

  On the other hand, the information storage control function 8 attached to the CPU 7 records detailed information (information) during the recording operation such as the recording time and the error contents during the recording operation simultaneously with the recording operation of the video signal inputted from the outside. Information necessary for maintenance of the recording / reproducing apparatus) is controlled to be stored in the nonvolatile memory 14 (information storage means). When the user confirms the state of the information recording / reproducing apparatus, the user inputs a command according to the screen to the setting menu control function 9 (first maintenance information display means) using the user interface 18, and as shown in FIG. A normal menu (first display mode) such as a serviceman menu or a search menu is displayed. FIG. 2 is a diagram showing a detailed display example of the maintenance function in the information recording / reproducing apparatus according to the embodiment of the present invention. From these normal menus, you can check the details of various statuses related to information recording / playback devices, such as video signal recording time, alarm recording list, error log list, and initialization commands required for maintenance. It is possible to input. In the embodiment of the present invention, for example, an external monitor can be used as the display means. However, a display device such as an LCD (Liquid Crystal Display) installed in the apparatus main body may be used. A simple device such as an LED (Light Emitting Diode) or a lamp or a voice expression may be used as long as it can be displayed and expressed.

  FIG. 3 is a diagram showing a simple display example of the maintenance function in the information recording / reproducing apparatus according to the embodiment of the present invention. The quick maintenance menu (second display mode) as shown in FIG. 3 displays the minimum necessary information so that the state of the information recording / reproducing apparatus can be easily grasped when performing maintenance. The display of the quick maintenance menu is controlled by the quick maintenance menu control function 10 (second maintenance information display means), and information determined in advance from the detailed information at the time of the recording operation stored by the information storage control function 8 Only take out and display. That is, the information simplified than the information displayed by the setting menu control function 9 is displayed.

  The display of the quick maintenance menu as shown in FIG. 3 indicates whether or not the recording operation, which is the highest priority function of the monitoring recorder, is continued without any problem, for example, “1. Is recording operation? OK”. The display contents can be understood at a glance. The method for determining whether or not the recording operation is continued without any problem is that the quick maintenance menu control function 10 investigates and records the recorded information from the alarm list of the alarm list search, for example, from the current time to a certain date and time. It is judged whether the operation is continuously executed without any problem. Similarly, the display of “2, what is the past log? ... severe 0 / minor 3”, for example, the quick maintenance menu control function 10 investigates the contents of the log list, and depending on the contents of the investigation results, it is severe and mild. By displaying the number of each occurrence log separately, it is possible to quickly and accurately grasp the status of the information recording / reproducing apparatus when performing maintenance. In addition, the alarm list search screen and log list screen can be called directly from the quick maintenance menu and displayed on the screen so that the details of each item listed in the quick maintenance menu can be confirmed as necessary. .

  Thus, as a means for displaying the status of the information recording / reproducing apparatus, by providing a means for displaying detailed information and a means for displaying simplified information, from general users to those who have specialized knowledge, respectively. By grasping the state of the apparatus that meets the purpose, maintenance can be performed efficiently.

  In the quick maintenance menu, as shown in the lowermost part of FIG. 3, the quick maintenance menu control function 10 (display range limiting means) limits the information display range to a predetermined range, so that the information can be displayed for a certain period. Information can be displayed. By minimizing the information to be displayed, the state of the information recording / reproducing apparatus can be grasped more easily, and the data amount of the information to be displayed can be reduced. Further, the quick maintenance menu control function 10 (display range specifying means) specifies an information display range within an arbitrary range by performing a cooperative operation with the user interface 18 and the setting menu control function 9, and the quick maintenance menu is used. The user can arbitrarily specify the period of information to be displayed. Therefore, it is possible to grasp the state of the information recording / reproducing apparatus in an arbitrary period. Note that the command input to the quick maintenance menu control function 10 may be performed not from the user interface 18 but from a dedicated command input unit of the quick maintenance menu control function 10. As a result, the function becomes easier for the user to use. Each of the information storage control function 8, the quick maintenance menu control function 10, and the setting menu control function 9 may not be configured independently in the system, and is incorporated in the CPU 7 as a software function. Also good.

  Thus, by limiting the display range and minimizing information, the amount of information to be displayed is reduced, and the state of the information recording / reproducing apparatus can be more easily grasped. Further, it is possible to grasp the state of the information recording / reproducing apparatus in an arbitrary period according to the user's designation.

  When maintenance is performed from a remote location outside the information recording / reproducing apparatus, the CPU 7 controls to transmit the information of the information recording / reproducing apparatus to the outside via the LAN interface 13 (information transmitting means). In conventional maintenance from a remote location, the information recording / reproducing apparatus has to transmit a large amount of data such as an alarm list and a log list as shown in FIG. However, in the embodiment of the present invention, the amount of data is reduced as compared with the prior art by minimizing display contents such as specifying a period, so that when transmitting to a remote place via the LAN interface 13, a narrow band is required. However, there is an advantage that transmission can be performed in a short time with little influence. Also, when information is stored on different media using the DVD drive 11 or the USB interface 12, the information data amount is small, so that it can be recorded in a short time. The maintenance information may be transmitted to a remote location not only in response to an external command, but also periodically from the information recording / reproducing apparatus or when an event occurs. Further, the transmission means to the outside may be transmitted not only to the LAN interface 13 but also to other serial interfaces such as RS232C, a telephone line, and a mobile phone by taking advantage of transmitting data with a small amount of information. .

  As described above, in the information recording / reproducing apparatus, by narrowing the display contents of the state of the apparatus, such as specifying the period, to the minimum necessary data amount, it is a narrow band when transmitting to a remote place. It is possible to transmit in a short time with little influence.
