Setting the Transmitting Image Quality
Setting the Transmitting Image Quality
This section describes how to set up the transmitting image quality using the
“Transmitting Image Quality” screen of the Video Setup menu.
There are five Transmitting Image Quality pages (Page 1/5 to 5/5). Each page
allows set-up of the transmitting image quality for each video input.
The following illustration shows an example screen of Page 1/5 for HD-SDI 1.
When “Setting Mode” is set to “Auto”, “Motion Smoothing Filter”, “2D
Smoothing Filter” and “Frame Rate Control” are automatically set to “Auto”
and all three items are automatically adjusted to the optimum value for the
selected communication bit rate.
When “Setting Mode” is set to “Detailed Setup”, you can set up each item
individually. Refer to the following description for setup.
Motion Smoothing Filter
The motion smoothing filter compares the current frame of an input video
signal with that of the adjacent frame and smoothes the temporal variation of
each pixel. The use of this filter reduces random noise included in the video
signal. It is useful when the camera is shooting a dark place, the video signal
from the S-VIDEO input is being transmitted or in other situations where
random noise may occur easily.
The filter is also effective for smoothing picture motion as a consequence of
enhanced correlation between frames, as well as improving the coding
efficiency. If the filter is activated when the bit rate is the same, block noise
will be reduced and the picture quality may be improved. On the other hand, if
the intensity of the filter is too much, afterimage may remain at portions where
there was motion in the picture, being viewed as a trajectory.
2D (two-dimension) smoothing filter
The 2D smoothing filter smoothes the variation of pixels in one frame of an
input video signal. The use of this filter reduces random noise included in the
video signal. It is also effective for improving the coding efficiency as a
consequence of reduction of high frequency components (detailed picture) in
the video signal. If the filter is activated when the bit rate is the same, block
noise will be reduced and the picture quality may be improved. On the other
