In the frame "Adjustments" carry out optimal adjustment for the quality if the image received.

All the settings take effect immediately upon pressing ―Apply‖ button without closing this dialog box.

Use this feature for instantaneous control of the changed made.

3.5.2 Selection of the snapshot fragment to view:

Click ―Sizes‖ tab (Fig. 5). Press ―Refresh picture‖ button, at the center of the area you will see a

snapshot taken at the moment of pressing this button. With the mouse, stretch the image in order to

get the size of the picture for convenient viewing. This is the full snapshot taken by the video camera.

Drag the lighter rectangle at the center of the snapshot on that part you want to view and stretch it by

corners until it gets the required size. Only part of the image that contains within this light sector will be

displayed in the video window.

ATTENTION! The sizes of the video image must not exceed maximum sizes set through the

"Coder" menu of the main window, menu item "Settings"; otherwise, you will get an error

message.

Click ―Coder‖ tab (Fig. 6). Choose the mode of video image compression: with time-independent

quality or with automatic regulation of the video stream.

In the mode ―Time-independent quality‖, the preset quality will be maintained, and with reduction of the

channel throughput, the baud rate of the video image transmission will get lower. Maximum quality

(clearness) corresponds to the minimum compression — Compression 2.

When applying ―Stream regulation‖ the baud rate for data transmission over this channel may be

limited with setting the range of quality variation. With reduction of the channel throughput, first, the

quality of the image transmitted will get worse, and upon reaching maximum compression set by you –

the rate of the video transmission will get slower.

In the frame ―General‖ set the basic parameters: compression of the base snapshot, maximum

number of the snapshots per second for this video channel and ―Refresh rate‖ of the base snapshot,

i.e. the number of the intermediate snapshots (alterations) between the base ones. The more numeric

values for Base snapshot compression and for Refresh rate, the higher the rate of the transmission,

though the worse the quality of the video image.

Click ―Events‖ tab (Fig. 7).

This mode may be turned off or on manually or turned on automatically in case of connection

disturbance (or at disconnection by the operator). Choose required option from "Standby mode" drop-

down list
