Main Tab: Video Screen
The “Main Tab: Video” sub-tab (Figure 3) is a “user-configurable” screen to select the video encoder parameters for the
input program.
Source:
allows the user to select the type of video input source. Options are: Composite, Component, VGA, and HDMI.
Bitrate:
user must enter the bitrate for the input video. It is recommended that the bitrate of the input video does not
exceed
“TS Bitrate”
selected on the
“Main Tab: TS Config”
screen (see of "Main Tab: TS Config" section).
Closed Caption:
the process of passing the EIA-608 Closed Captioning (CC) information and displaying the CC text
on television or other visual display. Options: Enabled and Disabled. (Factory Default: “Disabled”)
Video Filter Level:
a two-dimensional low-pass filter controlling the degree of which the input video is filtered.
Options are: Off (no filtering), On-Level 1, On-Level 2, On-Level 3, and On-Level 4 (highest filtering
coefficient). Level 1 filtering of the video will smoothen the sharp edges of the pixels and produce a softer
image. The softer an image, the less number of bits required to encode the image at the quantizer level.
Video Coding Mode:
user must select the Video Coding Mode. Options: Frame and Field. (Factory Default: "Frame")
HDMI Colorspace:
allows the user to select the color space of HDMI input source. Options: RGB and YCbCr.
(Factory Default: "RGB")
NOTE:
If the displayed pictures are very green or violet in color, it is a good indication that
this setting is incorrect.
GOP Size:
the length between I-frames is known as the group of pictures (GOP) size. The range is 1 to 120 with 1
I-frame for every 14 non-I-frames. (Factory Default: "15")
Test Pattern:
the video pattern that will be inserted into the transport stream if no input video is detected. Options:
Color Bars, Black Screen, Blue Screen, and Red Screen.
