Video streams
Entries for a sample video stream are shown in
Figure 37
. The relevant entries are:
Name
- A descriptive name (e.g.,
duplex video
,
tx video
etc).
Media Type
- Choose H.264 video.
Media Direction
- Relative to the unit making the outgoing call, the choices here are
Bidirectional
,
Transmit Only
(outgoing from this LiveShot), or
Receive Only
(incoming to this LiveShot).
Video Lines
- 1080 or 720 (HD), 576 or 480 (SD), or lower resolutions are
selectable.
Frame rate
- This entry is relative to the input frame rate. The choices are:
Full rate
-The video will be encoded at the same rate as the input.
Half rate
- The video will be encoded at half the frame rate of the input (e.g., 50 Hz input = 25Hz
encode rate) Other fractions of the native input frame rate are available.
As an example, if the input video frame rate is 24fps, 1/2 rate will be 12fps, etc.
Bit Rate
- In bits per second, the target encoding rate desired (256000-10000000).

*Special note: When the CrossLock VPN function is being used, the system has license to reduce the
Bit Rate and Frame rate Parameters dynamically based on network conditions. This is known as
“throttling” and can be disabled in the settings. When throttling is active, the Bit Rate and Frame
Rate settings are considered the maximum that should be attempted by the CrossLock system.
