5 Forcing I-frame W
In systems where a large GOP is used it may be necessary to
force to generate an I-frame to assist the decoder that needs I-
frame to start decoding
6 Video
Bitrate(Mbps)
R/W Video encoding bit rate that limits the maximum encoding bit
rate with the unit of Mbps. Value “0” of this field means
default encoding rate, 12Mbps. The encoding rate can be set
from 0.1Mbps ~ 30Mbps.
Note: Maximum encoding rate can be set to 40~45Mbps. But
there may be some juddering on this encoding rate.
7 Frame or Field
Rate
R/W Video frame rate setting ranged from 0 to 30 integer value.
Value “0” means the input frame rate. The reducing frame rate
is useful to reduce the total bandwidth for video transmission.
If the
Video Bitrate
⑥
is same and the frame is reduced to
half, then actual encoding bit rate would be half of the
specified video encoding rate.
8 Real video
Bitrate(Mbps)
R Actual video encoding rate. When the frame rate is low, such
as 1 or 2, the encoding rate cannot be done as specified in
the
Video Bitrate . So, this shows the actual encoding rate.
Below capture shows an example of this case.
9 OSD Status R/W Turn “On Screen Display” on or off. The OSD will show
encoding frame rate, bit rate and QP value for system
debugging. The QP stands for a quantization parameter that
means complexity level of the encoding. Low value shows the
low loss encoding and high value means higher loss encoding
from the original video quality.
10 Submit W All the values on this web page will be written to the system
when this button is clicked.
11 Refresh R All the values of the system on this web page will be read
from the system and displayed when this button is clicked.
