Configuration and Settings
93
Media
The Media tab, shown above, enables you to manually define the
encoding-related parameters used to configure audio and video, as follows.
NOTE
The Advanced button provides additional media settings, calibration
network interface connections, license and utilities options. These
options are only for technicians; they are password-protected and are
not described in this manual.
CODEC
Select H.264 (default) or External CODEC, as described below. The
configuration parameters displayed in this window change according to the
CODEC that is selected.
H.264
The H.264 CODEC is the default option, which supports all Resolutions. It is
shown above in Figure 73.
The H.264 CODEC is an improved video encoder. It allows near realtime
encoding and supports an adaptive bitrate, which increases resiliency.
If the bitrate drops, then the video stream does not flicker or freeze. It also
allows encoding in near real time, enabling up to Full D1 video images in both
NTSC and PAL at full frame rate.
• Limit Video Rate: The video rate is set automatically by the application
following calibration. You can override the video bitrate by selecting the
Limit video rate checkbox and then setting it manually after calibration
has taken place. The recommended video rate range is displayed under the
field along with the currently selected Profile and Resolution. The
recommended range varies according to the selected Profile and
Resolution.
• Support 4:2:2: Specifies that the LU supports encoding video with 4:2:2
color profile.
