Hints
• When connecting Meetings using H.239 with a specified [Max Bandwidth (ep)],
bandwidths specified as [H.239 Bandwidth] will be used with [H.239] and the
remaining audio bandwidth will be subtracted and used as video bandwidth.
However, if the video bandwidth is lower than 128 Kb/s, that 128 Kb/s will be saved
for video bandwidth and the remaining bandwidth will be allocated to H.239.
• Apart from the [Max Bandwidth] category which is used to set video and audio
bandwidth, [H.239 Bandwidth] can be used to configure bandwidth used for H.239
Presentations.
H.239 Presentation bandwidth restriction is applied to the transmission of application
images.
• The bandwidth used for connections between the sending Endpoint and the meeting
server will be determined by comparing the H.239 rate setting of the terminal and
the [H.239 Bandwidth] of the Meeting, and selecting the one with the lower value
for transmission.
• The Meeting's [H.239 Bandwidth] will be used when transmitting from the server
to the receiving endpoint.
Note
If [H.239] is set to [ON], there may be problems displaying video on H.323 terminals
that do not support H.239. In such a case, set the Meeting's [H.239] to [OFF].
About Bandwidth
[Maximum Bandwidth (ep)] refers to the maximum bandwidth each endpoint
can send to the Meeting server per channel.
[Max Bandwidth] defines total audio and video stream bandwidth that can be
used for a meeting.
When [Bandwidth Control] is set to [STATIC], a Meeting cannot be connected
if participants' total bandwidth exceeds [Max Bandwidth] even if the
maximum number of members has not been exceeded.
When [Bandwidth Control] is set to [DYNAMIC], the [Max Bandwidth] is
allocated equally among the Meeting members. However, the number of
people participating in a Meeting cannot exceed the specified [Max Members].

Configuring a Meeting
Description
Under default conditions, this is set to half the value specified in
[Max Bandwidth (ep)].
Select from [H.263+] or [H.264] for the codec to use for H.239.
Note
Select [H.263+] when conducting meetings that include SD quality
Endpoints. If you select [H.264], H.239 is not sent to the SD quality
Endpoints.
Select [ON] to use the Application Sharing function via VNC
protocol.
Enter the maximum bandwidth used for the Application Sharing
function.
The default setting is [2048] Kbps.
