Event Playback

The Event Playback dialog box was designed to assist in easily and rapidly reviewing the event content captured during audio and video capture sessions. This dialog window displays a list box that contains an entry for each captured event and a window for reviewing captured video images. In addition, there are several controls for playing one or several items, moving forward and backwards through the event list and clearing the events.

You can select a group of items to play from the list box (using the Control-key and mouse or Shift-key and mouse) and then press the Play Selection button to begin to play the selected items.

You can also control the scaling of the image. If you turn on scaling, Eyes-N-Ears will automatically fit the captured image in the playback dialog box. It should be noted that you can adjust the size of the dialog box to fit your screen. Eyes-N-Ears remembers the size and automatically restores it upon entry. So, if you capture large images, you can stretch the dialog box as big as you need to avoid scaling.

If you turn off scaling and you used a floating-target to capture images, Eyes-N-Ears will super-impose a white rectangle over that captured image to show where the floating-targe t was specified for each image.

As each item is being played, the file name appears in the event file lines located below the list control box. The top line displays the current/last audio file. The lower line displays the current last video file.

The list box provides 4 columns of data for each captured event:

Type/ID | The type of event is depicted by either a camera for a video event or a microphone for an audio event. In addition, the event ID number is displayed in this column. Video and audio events maintain separate ID counters, so you may see duplicate ID numbers in this column. This is normal.
Time | Eyes-N-Ears records the timestamp that indicates when each event occured. The time is reflected in MM/DD-HH:MM:SS format.
Rating | Each event is assigned a rating of 0-100. This number reflects the percentage of data in the event file that exceeded the peak threshold set during calibration at the beginning of the session. The higher the number, the more significant the event. Note that manually captured events have a rating of 0. This is normal operation.
File Name | The file name and path of each event is displayed in this column. Due to size restrictions, this column is normally not viewable, but you can scroll it into view by using the horizontal scroll bar at the bottom of the list box.

Shortcut Control

The shortcut control is a graphic that is displayed on the main window of the Eyes-N-Ears application. You can use the mouse with this control to interact with some of the various operations of Eyes-N-Ears. The control (below) will be described from top to bottom:

Picture Count | The picture count window displays the current number of video event files that can be reviewed. This count will be updated everytime a new video frame is captured. It will also be reset to 0 when the events are cleared.
Sound Count | The sound count window displays the current number of audio event files that can be reviewed. This counter will be updated as new audio capture events are recorded and when the events are cleared from the playbck dialog box.
Manual Capture | The two buttons that belong to this group will allow you to capture a single video or audio session. This is basically a "one-shot" operation, so the session will end after the 1st video or audio file is captured. The session starts immediately with no calibration being performed during the start up phase.
Auto Capture | The auto capture button group allows you to start either an automated video capture session or an automated audio capture sesssion. These are exactly the same types of operations that are available from the drop-down menus.
Play | Pressing the Play button will cause the Playback dialog box to be displayed. You will then be put into a playback session.
Stop | Pressing the Stop button during the middle of an automated audio or video capture session will cause that session to terminate.
