Minimum Quantizer—A parameter related to video quality. A higher quantizer value
means less video quality but less bit rate, and vice versa. The value range is from 2 to
31.
Maximum Quantizer—A parameter related to video quality. A higher quantizer value
means less video quality but less bit rate, and vice versa. The value range is from 2 to
31.
Input Filter Mode—The level of filtering applied to the video signal before it is encoded,
helping to remove high frequency noise from lower quality cameras or noisy video
feeds.
Resolution—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.
Rate Control Mode—The mode controlling the bit rate variation. The available modes
are:
CFR (Constant Frame Rate)—This mode maintains the target frame rate. Video
quality may suffer and the bit rate may exceed the target value.
CBR (Constant Bitrate)—This mode is the most effective to maintain the target bit
rate. Video quality may suffer (frames may be skipped) and the frame rate may
decrease. This mode should be used when transmitting video over networks that
have very limited bandwidths, and with an intra interval value of 0.
CNR (Constant Nextiva)—This is the optimized mode to be used only for the Nextiva
enterprise video management software.
Web Multicast IP Address—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 31).
Web Multicast IP Port—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 31).
Intra Interval—The frequency at which a complete video frame (called I-frame) is sent
by the encoder. Possible values are in the 0–1000 range. A value of X means that a
complete image refresh will occur every X frames.
Note: It is not recommended to use a value of 0.
Compression Mode—The way the video is compressed. The following modes 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.
Note: You need to reboot after changing the compression mode to MJPEG on the
S2750e devices for the change to take effect.
