Suppressing Video Refresh Requests from Endpoints
Suppressing Video Refresh Requests
from Endpoints
Depending on the Endpoint, video refresh requests may be made to the server
when packet loss occurs, for example. As the server transmits intra-frames in
response to each video refresh request, the quality of the video transmitted
from the server may decrease when several refresh requests are made, for
example, during meetings with a large number of Endpoints.
When you use the ISC (Intraframe Suppression Control) function, intra-frames
are transmitted only during specified time intervals, instead of in response to
each video refresh request. This allows you to give the appearance of improved
video quality.
You can configure the ISC function in the [Detail] tabs of the [Add Meeting]
and [Edit Meeting] screens.
