DVI Broadcaster DL User Guide
Below is a table showing the streaming settings that are configurable.
Table 6 Streaming settings
Show time label If the video needs to be time labeled or timestamped, this
parameter allows how the date and time will be displayed.
Click on
Show substitutions and use the Format
substitutions commands to select the desired date and
time format. The commands are described in a table
below.
If time labeling is not required, leave this field blank.
Frame size Select a frame size from the drop down list to limit the
width and height of the video image. If the video source is
sending resolutions larger than the resolution limit
configured, the video image will be scaled to the
resolution limit. Limiting the frame resolution can help to
reduce bandwidth usage.
Key frame interval Controls the number of frames. Key frames define the
starting and ending points of any smooth transition.
Limit frame rate Enter a value in terms frames per second. This field is
used to set a frame rate that is lower than the maximum
frame rate at which the DVI Broadcaster DL can capture
images. Reducing the frame rate reduces the number of
images being captured by the device. Decreasing the
frame rate can help to reduce bandwidth usage.
Bitrate Enter a DVI signal bitrate. A lower bitrate produces lower
quality videos and smaller file sizes. A higher bitrate
produces better quality videos and larger file sizes.
Quality parameter (for
MJPEG only) This parameter is similar to Bitrate. Use bigger values to
improve the quality of the broadcast.
