1. Will you tell me what is bandwidth required for point to point video conferecning???
Bandwidth utilization depend on two most important thing i.e. frame rate and resolution for video, I attached image which define matrix for bandwidth usage in reference to frame rate and resolution.
You can set following details using following configuration:
xConfiguration Video Input Source [1..3] optimalDefinition Profile
The Video Input Source Quality setting must be set to Motion for the optimal definition settings to take
The optimal definition profile should reflect the lighting conditions in your room and the quality of the
video input (camera); the better the lighting conditions and video input, the higher the profile. Then, in
good lighting conditions, the video encoder will provide better quality (higher resolution or frame rate)
for a given call rate.
Generally, we recommend using the Normal or Medium profiles. However, when the lighting
conditions are good, the High profile can be set in order to increase the resolution for a given call
Some typical resolutions used for different optimal definition profiles, call rates and transmit frame
rates are shown in the table below. It is assumed that dual video is not used. The resolution must be
supported by both the calling and called systems.
Use the Video Input Source OptimalDefinition Threshold60fps setting to decide when to use the 60
fps frame rate.
Requires user role: ADMIN
Normal: Use this profile for a normally to poorly lit environment. Resolutions will be set rather
Medium: Requires good and stable lighting conditions and a good quality video input. For some
call rates this leads to higher resolution.
High: Requires nearly optimal video conferencing lighting conditions and a good quality video
input in order to achieve a good overall experience. Rather high resolutions will be used.
Example: xConfiguration Video Input Source 1 OptimalDefinition Profile: Normal
2. Is it ok if i give one C20 for each location. ( just i need point to point call).: - You can use individual C20 and you can make point to point call using IP address, till they are reachable to each other
