Video Bit Rate
Configures the bit rate for video call. It can be selected from the dropdown
list. The default setting is 2048 kbps. The valid range is from 32 – 2048
kbps.
Note: The video bit rate can be adjusted based on the network
environment. Increasing the video bit rate may improve video quality if the
bandwidth is permitted. If the bandwidth is not permitted, the video quality
will decrease due to packet loss. For some network environment, the
default setting “720P” might be too high that causes no video or video
quality issue during video call. In this case, please change “H.264 Image
Size” to “VGA” or “CIF” and change “Video Bit Rate” to “384kbps” or lower.
SDP Bandwidth
Attribute
Sets the SDP bandwidth attribute. It can be selected from the drop-down
list. The default setting is “Media Level”.
• Standard: use AS format in session level; use TIAS format in media
level
• Media Level: use AS format in media level.
• Session Level: use AS format in session level.
• None: no modifications in the session format.
Note: Please do not modify this setting without knowing the session format
supported by the server. Otherwise, it might cause video decoding failure.
H.264 Payload Type
Specifies the H.264 codec message payload type format. The default
setting is 99. The valid range is from 96 to 127.
Presentation Settings
Disable BFCP
If set to "Yes", the device will be unable to receive the presentation stream
in video calls and video meetings.
Initial INVITE with Media
Info
Initial INVITE SDP contains presentation media.
Presentation H.264
Image Size
Selects the H.264 image size.
Presentation H.264
Profile Type
Select the Presentation H.264 Profile Type from "Baseline Profile", "Main
Profile", "High Profile" and "BP&MP&HP". The default setting is
"BP&MP&HP". The lower the profile type is, the easier the packet can be
decoded. However, higher level has high compression ratio. For device
with low CPU, select "Baseline Profile" to play record; "Baseline Profile" is
more likely to be used in a video conference that has high demanding for
the video quality. Select among the three types to achieve best video effect.
Presentation Video Bit
Rate
Configures the bit rate of the video. The video bit rate can be adjusted
based on the network environment. Increasing the video bit rate may
improve video quality if the bandwidth is permitted. If the bandwidth is not
permitted, the video quality will decrease due to packet loss. Video Bit Rate
can be set to integer value from 512kbps to 2048kbps.
