  As shown in FIG. 2, on the recording work screen 51, the recording state of each event can be confirmed on the time chart screen 52 and the recording list screen 54. However, in order to confirm other events from the large number of events to be recorded, for example, the time chart 55 is scrolled in the time axis direction by operating the scroll button 52a or the scroll bar 52b of the time chart screen 52, It becomes necessary to switch the screen page.

  When the time chart 55 is scrolled in the time axis direction, the state of each event near the current time becomes invisible on the time chart screen 52. On the other hand, the automatic recording application 31 displays the event state icon 53 in a drawing process on the recording work screen 51 in an unlinked manner with scrolling in the time axis direction of the time chart screen 52.

  As a result, the event status icon 53 displays the current time and the status of the event near the current time, the time to start recording, and the remaining recording time if recording is in progress. Even if the screen 54 is scrolled, the state of the event near the current time can always be confirmed.

  As described above, in the recording system according to the present invention, the time chart screen 52 and the recording list screen 54 are close to the current time in the recording system 1A that automatically records video and audio signals by controlling the recording device such as the video tape recorder 2. Even in a state where other than the above are displayed, event information around the current time related to each video tape recorder 2 can always be drawn on the event state icon 53.

  With the event status icon drawn for each video tape recorder 2, it is possible to confirm at a glance important information such as the recording start time and the remaining recording time of the event, whether the video tape recorder 2 is on standby or recording. It is possible to contribute to the efficiency of the operator's system monitoring work.

  Since the event status icon 53 is displayed by an automatic recording application executed on the control terminal 5, it can be handled without changing the hardware configuration of the existing recording system, and provided at a low cost. Can do.

  The present invention is applied to a recording system that is installed in a broadcasting station or the like and automatically records video and audio signals distributed from a plurality of lines on a predetermined video tape recorder or the like.
