6. In the Noise Reduction Filter Mode list, select the filtering of small variations in
pixels in otherwise motionless sections of the video, to be used in all conditions to
reduce the bit rate. Using this filter also helps reduce the number of false alarms in low
light conditions. The available values are Low (default), Medium, High, and None.
7. In the Resolution list, select the measure of how clear and crisp the video image
appears. Each resolution corresponds to a specific number of pixels (columns * lines)
for each picture of the video sequence. The available resolutions are: QCIF, CIF, 2CIF,
4CIF, All lines, 2/3 D1, and VGA.
8. In the Web Multicast IP Address box, enter the IP address of the multicast group
from which the web interface will get live video, if the web streaming method is
Multicast UDP (see page 88). This parameter applies to Input 1/Encoder 1 only.
9. In the Web Multicast IP Port box, enter the IP port of the multicast group from which
the web interface will get live video, if the web streaming method is Multicast UDP (see
page 88). This parameter applies to Input 1/Encoder 1 only.
10. In the Frame Format list, select the way the video fields are compressed. The
available values are:
Field over Field—The proprietary mode used by the Nextiva edge devices.
Interlaced Frame—The MPEG-4 compliant mode where the two video fields are
interlaced.
Deinterlaced Frame—The MPEG-4 compliant mode where the two video fields are
converted to a progressive scan image by a deinterlacing filter. This filter removes
interlaced artifacts for playback on a progressive scan monitor.
11. In the Rate Control Mode list, select the mode controlling the file size variation. The
available modes are:
CFS (Constant File Size)—The quality of the images may vary, but their size will be
targeted to the value specified by the Target File Size parameter.
VFS (Variable File Size)—The quality of the image is set by the Variable File Size
Quality parameter, but the size of the image will vary, depending of the encoded
image.
12. In the Target File Size box, enter the target size of each image that will be encoded
(in Kbytes), if the rate control mode is CFS. The available values are in the 1–100
range.
13. In the Variable File Size Quality list, select the quality of the encoded images, if the
rate control mode is VFS. The value range is from VFS1 (high quality) to VFS7 (worst
quality).
14. To continue the configuration process, select another parameter category in the
navigation pane. Otherwise, click Apply to save the changes in the device. Depending
on the changes you made, a reboot may be required; follow the on-screen instructions
in the Device Configuration Submittal pane.
