Video Snapshots

You can send a still frame from any of your site's local video sources to the other participating site(s) using the SNAPSHOT button on the ViewStation remote control.

Sending successive snapshots from one camera and the live feed from another offers an excellent way to provide still frames of transparencies and continuous video of a speaker simultaneously when making a video presentation to another site.

To initiate snapshot mode:

Press the SNAPSHOT button
Select a camera by number using the numeric keypad on the remote unit
Position/zoom the selected camera as required
Press SNAPSHOT again to send the image to the other sites.

Once the "snapshot" mode is enabled, a far site will see your still frames on the monitor that normally shows its own outgoing signal, and your live video on the monitor that shows its incoming signal. Their own outgoing video will be displayed in a small picture-in-picture screen on their "incoming signal" monitor, after a few seconds.

Use of this mode is initiated by the site that sends the snapshots, but it is cancelled by activating the NEAR camera at the receiving site(s). The mode also times out at the receiving site(s) if the snapshot is not updated for several minutes.

Note that the receiving sites cannot adjust their own cameras without selecting their NEAR camera (and thus losing the currently displayed snapshot). If a receiving site makes a camera adjustment during a sequence of snapshots being sent from the other site, the first new snapshot arriving from the sending site will re-establish snapshot video mode at the receiving site.
