Encoder Settings

Item

Description

Enable

All encoders are enabled by default. Use this check box to disable/re-
enable this specific encoder.

Video bit rate
mode

Controls variations in bit rates.

Constant
quality

Keeps the image quality constant, with varying
network load. The quality is determined by the value
set for the Quality parameter (see below).

Constant bit
rate

Keeps network load constant at the cost of varying
image quality. Frames may be skipped.

Resolution

Set sensible combinations of mode, resolution, frame rate and
(maximum) bit rate. It is advised to limit MJPEG encoding to 5 fps
when the BC840-MC is also handling MPEG-2/4 encoding with 1xD1
and 1xCIF or 2CIF at full frame rate.

Frame rate

(Maximum) bit
rate

Actual bit rate

Constant
Quality Mode
(CQM) only

This field is dynamically updated with the current bit
rate to provide feedback on the bit rate that is used
on average with the current Quality setting.

Quality

Constant
Quality Mode
(CQM) only

Reflects the amount of compression. Generally
speaking: the higher the quality setting, the lower
the compression ratio and the more bits are
consumed. This means a trade-off has to be found
between the desired quality level and available
bandwidth.
