H.264 Profile Type
Video Bit Rate
SDP Bandwidth Attribute
Firmware Version 1.0.3.6
Note: 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.
It is used to set the H.264 profile type. It can be selected from the
dropdown list.

Baseline Profile

Main Profile

High Profile

BP/MP/HP
The default setting is "Baseline Profile".
Note: Lower levels are easier to decode, but higher levels offer better
compression. Usually, for the best compression quality, choose "High
Profile"; for playback on low-CPU machines or mobile devices, choose
"Baseline Profile". If "BP/MP/HP" is selected, all three profiles "Baseline
Profile" "Main Profile" and "High Profile" will be used for negotiation
during video decoding to achieve the best result. This is usually used in
video conference when there is higher requirement on the video.
It is used to configure 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.
It is used to set the SDP bandwidth attribute. It can be selected from the
drop down list.
