Aggregate bit rate limits determine the number of simultaneous recordings and live streams that are allowed.
NOTE: Setting bandwidth limits is optional. Change these settings only if your network cannot handle the number of simultaneous recordings and live streams that LifeSize UVC Video Center supports.
Lowering bandwidth limits does not affect recording and streaming that is in progress. New limits apply to all activity after the change is made.
Administrators view and edit bandwidth limits in Administer : System Settings : Bandwidth limits - Edit.
| Setting | Description |
|---|---|
| Recording bit rate (in kb/s) | Sets the total bit rate limit for recordings (incoming and dial out). Valid values are 0 to 16000. A value of 16000 is equivalent to 40 SD or 20 HD recordings. Setting the limit to 0 disables recording.
NOTE: The number of recording licenses activated on the system determines the upper limit of allowed recordings. The recording bit rate includes both incoming streams and dial out recordings, so that the number of dial out recordings in progress affects the recording capacity for incoming streams. For example, with 3 HD dial out recordings in progress, the capacity for recordings initiated by the video systems is 17 HD recordings. |
| Dial out bit rate (in kb/s) | Sets the total bit rate limit for dial out calls. Valid values are 0 to 3840. A value of 3840 is equivalent to 5 HD dial out recordings. Setting the limit to 0 disables dial out recording.
Dial out recordings use the CPU for transcoding video. The dial out bit rate is limited to conserve CPU resources. If your LifeSize UVC Video Center is deployed on a virtual machine, set this value according to the CPU capacity available on the virtual machine. This setting also applies to video transcoding used to create dual streams and mobile formats. |
| Viewing bit rate (in kb/s) | Sets the total bit rate limit for videos (live and recorded) with viewing in progress. Valid values are 0 to 800000 (800 Mb/s). Setting the limit to 0 disables viewing.
The viewing bit rate includes both live and on demand viewing, so that on demand viewing reduces the bandwidth available for viewing live streams. |
| On demand viewing bit rate (in kb/s) | Sets the total bit rate limit for recorded videos with viewing in progress. Valid values are 0 to 268800. A value of 268800 is equivalent to 350 HD streams. Setting the limit to 0 disables on demand viewing.
The total on demand viewing bit rate depends on the read capacity of the hard drives. If your LifeSize UVC Video Center is deployed on a virtual machine, limit this value according to the disks used. |
