4. In the Contrast box, enter the range of colors in the image.
5. In the Saturation box, enter the intensity of the colors in the image.
6. In the Hue box, enter the relative amounts of red, green, and blue in a color.
7. In the Frame Format list, select the way the video is 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.
8. In the Number of Encoders per Video Input box, enter the number of encoders
receiving a video stream. Typically you use both encoders for video; however, to
activate the noise reduction filter (see page 31), you need to disable the second
encoder. The available values are:
1—To use Encoder 1 for video with the noise reduction filter set at Low.
2—To use both encoders for video.
9. 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.
Encoder
The video parameters are the same for the two encoders in the device. However, they vary
depending on the compression mode: There is one set of parameters for the SM4 and
MPEG4 Compliant Simple Profile modes, and another one for MJPEG.
To configure the encoder parameters for the SM4 or MPEG4 Compliant Simple
Profile compression mode:
1. In the navigation pane, expand Configuration > Advanced > Video, then click the
desired Encoder.
2. In the Compression Mode box, select SM4 or MPEG4 Compliant Simple Profile. The
compression mode represents the way the video is compressed. The following codecs
(coders/decoders) are available:
SM4—The proprietary MPEG-4-based mode.
MPEG4 Compliant Simple Profile—The MPEG-4 ISO 14496-2 compliant mode.
MJPEG—The Motion JPEG mode that uses standard JPEG still images.
