Figure 1 shows the block diagram of the device;

figure 2 - General view of the operator;

figure 3 - General view of the operator's workplace, where in the upper left corner is conventionally shown, the image obtained from one of the cameras.

The device comprises (1):

the video camera 1, the storage unit of the digital video signal 2, made for example in the form of electronic storage media of a personal computer, the conversion unit 3 of the digital video signal in a sequence of images what s on the screen of the monitor 4, performed, for example, in the form of a card of the personal computer 5, the device has performed in the form of a wheel manipulator 6 control block conversion unit, the device contains not shown in the drawings, the event analyzer emitting from the digital video signal events requiring the attention of the operator, and generates a signal forming label at selection events requiring operator attention. The event analyzer may be made in the form of additional computer having access to a memory in which is stored video information. The device has made in the form of a wheel indicator 6 events such that its rotation corresponds to the rotation of the manipulator control unit, and the badge depicts the labels 7 are recorded by a camera of events that require attention from the operator.

The device operates as follows.

The operator controls the situation on the protected object through the view real-time video and videos that are moved to the archive, for example, while viewing a delayed image. To navigate through image data is used, for example, the indicator recording time of the current frame or group of frames (timeline) and the scroll wheel (Figure 2).

The scroll wheel is the main tool operator to control supports rivellini modes when viewing video. With all the information about the current view is reflected in the timeline.

The operator uses the tools are designed to control the preview. In the absence of influence of the operator on the scroll wheel the scroll wheel Autonomous rotates, for example, from left to right, showing the process of shooting and routine, such as lap time. The timeline is located above the scroll wheel, informs the operator on the display scale of time, for example, the placement coordinates of time on the timeline. Also on the timeline can be located on the label or the risks related to detected or reported alarm events and risks that require immediate consideration by the operator can be colored red, labels, other events in the appropriate color. Central risk timeline can be painted in white color. The Central risk is intended to conditionally display the time is displayed on the screen of the event. Part of the timeline to the right of the Central white risks can be colored blue and conditionally may indicate future time left scale green, conventionally, it means the recording time of the archive. Above the timeline are fields display the date and time.

To view video archive operator uses mainly the scroll wheel as a control and the timeline, as a display item preliminary information. Also, with additional manipulator, the operator can select events on the timeline that allows you to jump to the appropriate personnel. The transition in the mode of viewing the archive by clicking on the scroll wheel as a normal button. Then on the scroll wheel inscription "live" (direct play) will change to "pause". At this point the right side of the timeline will be painted in green color. This is due to the stop of the Central risks relative to the current time ("live" Central white risk move with colour scale in green, so the movement is not noticeable).

To start viewing the archive you want to spend on the wheel (scroll) from left to right. The label will change to ">", which means direct playback of archive with a speed corresponding to the recording speed. Start viewing records the point in time at which the operator is switched to the playback mode of the archive.

The timing of the beginning of the interesting videos by scrolling archive in the opposite direction, to guide the operator needs to use the fields of the date and time that correspond to the timeline floor is the position of the Central white risks. To locate the start time of the desired video you can use the Overdrive mode scroll wheel. For example, the scrolling speed change exponentially, in accordance with natural units. That is, the visible part of the adjusting wheel, or 180 angular degrees may correspond to, for example, 1 second or 1 minute, or 1 hour, or one day or one month.

After using scaling was found interesting time on the scale, the operator can select the part of the archived videos for loop. For example, clicking ' I←→I" allows the selection of the fragment, and the use of markers defines the boundary of the slice. To confirm fragment button "I←→I" is pressed again. The timeline is formed is the time period that is gray, that corresponds to the video archive. Next, you should scroll wheel mode set the playback speed (button) ">" and the selected video will be played, for example, cyclically.

It should be noted that under the video refers to simultaneous recording on all cameras in the group when there are multiple cameras. That is, after selection of the slice to record one video camera can be provided synchro is a great reproduction of records other cameras for a specified time interval, that provides, for example, a detailed study of the situation from different angles. Also, when using mobile cameras may be used more screen showing the field of view on the location of one or more cameras.

Exit the view mode selected videos can be accessed by clicking on "I←→I".

In view of the archive, the operator can view the video on the staff, using the scroll wheel. For this purpose it is necessary to slowly scroll the wheel to the right or left, depending on which direction you want to view the video in the forward or reverse.

Exit the view of the archive by double-clicking on the scroll wheel is used, however, as the button.

In the case of determining the actual danger of the object, whose actions provoked the registration of disturbing events, this object can be visually selected by the operator on the frames, for example, by a frame in a frame in a contrasting color. Label the timeline, the corresponding frames on the specified object, can also be highlighted in a contrasting color, mostly red. After careful study of the video, the operator can clear the selection in the absence of danger. The transition from the od of the CSOs marked event to another, to view, can be done in steps, for example, by clicking the "I<" preceding event or and ">I" - subsequent event. To save viewed or edited clips can be used button 8, made in the form of a stylized image of the disk.
