OmniTek 2.3 manual Video Checking Features, Video Status Display

9. Video Checking Features

OmniTek XR has the ability to display real-time video status information and to detect and count various types of error. This status information and associated error counts are displayed in the Video Status window, which may be called up either from the Window menu or by clicking on the Video Status icon on the main (Window) toolbar.

Note: The aspects of the video that are checked depend both on the video format and on which additional packages are included in the OmniTek XR system that is being used.

Video Status Display

The Status window shows a range of information about the video being analysed, organised into a collapsible hierarchy that allows the user to select what is displayed according to their particular requirements. Sections of this hierarchy can be opened (and closed) by clicking on the +/- symbols displayed alongside the various headings that define the sections of the hierarchy – in the same way that clicking in Window Explorer opens or closes the folders within its file hierarchy.

Individual ‘leaves’ of the hierarchy (and sections) can also be hidden from display by right-clicking on the item and taking the option to Hide item from the submenu that appears. Moreover, if all the leaves within a particular segment of the hierarchy are hidden, that segment will also be hidden. (The context menu that appears on right- clicking also includes options that allow sections of the menu to be re-‘expanded’ after being hidden.)

There is also the option of a ‘Flat view’ (selectable from the Options menu) in which the same selection of details are seen but with only the section headings to indicate the presence of other parts to the hierarchy. In this view there are no +/- symbols on which to click to expand or collapse parts of the hierarchy but the context menu remains available to hide or re-expand parts of the display as required.

Another option is to show timelines that indicate graphically the rate at which different types of error occur by showing the number of errors experienced in a chosen sample time as a proportion of the total number of samples. These timelines are both selected and configured from the Options menu (see page 88)

As shown in the example displays below, the ‘values’ associated with particular status items are often shown coloured green, orange/brown or red to make it immediately clear whether the value currently being reported is OK (green) or incorrect in some way but not being used (orange/brown) or incorrect and being used (red). In addition, the heading line of unexpanded sections (together with the main ‘Video’ heading) may be marked with a cross in a red circle to indicate that at least one error has been detected among the items of that section. This provides a simple and effective way of, firstly, alerting the user to the fact that an error has occurred and, secondly, guiding the user to the relevant part of the status display.

Note: In all, an extensive amount of information can be displayed. If simply opening and closing sections of the hierarchy doesn’t give you the display you need, you can ‘filter’ the information down to just those items you are interested in (and save the filtering you select). This is described in the section starting on page 119.
