Using the internal web pages 

7.7.3. Live View

 

Encoder 

The C-54 E can stream MJPEG over UDP and HTTP.  

ƒ

 

To transport MJPEG over 

HTTP

 and/or to use the Live View previews in the web pages, 

enable the Live View Encoder and configure its settings.  

ƒ

 

To enable and configure 

UDP

/MJPEG streaming, go to the Encoder 1/2 tab, select MJPEG 

encoding mode and configure settings. 

 
Encoder settings 

Enable 

All encoders can be enabled and configured separately.  

Video bit rate mode - 

Constant quality

 

Keeps image quality about constant as long as 
the maximum bit rate is not exceeded. When 
that happens, frames are skipped. 

 - 

Constant bit rate

 

Keeps network load about constant. 

Resolution, Frame 
rate, Maximum bit 
rate 

Set sensible combinations of mode, resolution, frame rate, and 
maximum bit rate. It is advised to limit MJPEG encoding to 5 fps 
when the C-54 E is also handling MPEG-2/4 encoding with 1xD1 and 
1xCIF or 2CIF at full frame rate. 

Actual bit rate 

Shows the network load with the current settings. 

Quality 

Reflects the amount of compression. For instance, 80% picture 
quality equals 20% compression. This parameter can be used to fine-
tune picture quality for a given combination of settings. 

Show Preview>> 

Click to see live images and the effect of your settings. The preview 
is generated by the Live View Encoder. 

<< Hide Preview 

Hiding the preview may improve web page responsiveness.
