Resource Usage in AVC CP Conferencing
Video resources usage varies according to the video resolution used by the endpoints. The higher the video
resolution (quality), the greater the amount of video resources consumed by the MCU. The following table
shows the number of video resources used for each resolution.
The port consumption ratios of different calls against that of a HD720p30 call are as shown in this table.
