<WaterMark>
The WaterMark feature is a security feature that places data into the video stream. If the playback
of the content is pirated, it is possible to analyse the recording to work out when and where the
content was recorded.
Following is an example of the Watermark configuration options:
<WaterMark>
<Type>QRCode</Type>
<Enable>True</Enable>
<Time>
<Average>600</Average>
<Variable>60</Variable>
<FrameHold>1</FrameHold>
<FirstFrameHold>1</FirstFrameHold>
</Time>
<Appearance>
<Position>
<X>0.75</X>
<Y>0.25</Y>
</Position>
<Position>
<X>0.25</X>
<Y>0.25</Y>
</Position>
<Movement>
<Width>0.1</Width>
<Height>0.1</Height>
</Movement>
<Size>0.1</Size>
<Transparency>0.05</Transparency>
</Appearance>
</WaterMark>
When this option is active, a QRCode or text, will be displayed in the video stream at random time,
random positions. The Watermark will also display for as little as 1 frame and with transparency
making it very difficult to see. To remove the Watermark would require a frame by frame analysis
and hand removal of the code. This would be significant amount of work taking a very long time
and costing a significant amount.. There is also a good chance the code is missed.
The WaterMark options are:
 <Type> : The type of watermark. <QRCode> or plain text (Not yet supported). QRCode is
a encoded image including checksum data. (See:
http://http://en.wikipedia.org/wiki/QR_code )
 <Enable> : This option allows you to enable or disable the WaterMark feature.
 <Time> : This set of options set up the frequency of the WaterMark image.
