Content tx: <status>
This row (if present) shows one of two things: the characteristics
of the content video channel being sent by the MCU to a
participant, or the reason why no such stream is currently being
transmitted. The status values that can be shown here are:
Content tx: pending: The MCU is able to send content video to
the participant but is not currently doing so. This is normally
because there is no active content channel video source for the
conference. This status will also be shown for a participant which
is the content channel video source and is also capable of
receiving the currently active content video stream.
Content tx: disabled : Content is enabled for this conference, but
this participant is not allowed to receive it. To enable content for
this participant, configure the Content video receive setting for
this participant's endpoint (refer to Configuring H.323 endpoints),
or use the enable control for an active call.
Content tx: no common codecs: There is a per conference setting
that determines which video codec is used by the MCU for
outgoing transcoded content channels. The Outgoing transcoded
codec parameter is on the conference configuration page
(Conferences click on the conference to be configured, then
click the Configuration tab and go to the Content section). This
message means that the endpoint is able to receive content
video, but not using the same codec as the MCU is configured to
transmit.
Content tx: resolution mismatch, Content tx: bit rate mismatch:
For each conference, the MCU uses a single video stream for all
outgoing content connections to endpoints. This entails
considering all endpoints' receive capabilities and deciding
which resolution and bit rate to send in order to maximize the
number of content channel viewers. These messages mean that
the MCU has been unable to include this endpoint in the set of
content viewers because of its limitations with regard to video
resolution or bit rate. Note that it is possible to configure a lower
limit on the bandwidth of the shared content video encoding
which will cause a bit rate mismatch where an endpoint is only
able to receive a low bit rate stream (refer to Configuring content
settings).
Content tx: no common formats: This conference's configuration
specifies that the content channel is transmitted in 16:9
resolutions only. However, this endpoint does not support 16:9
resolutions. To allow the MCU to select a content resolution that
will accommodate the capabilities of all endpoints in the
conference, change the Transmitted content resolutions setting
in the conference's configuration to Allow all resolutions.
No Content tx status will be
shown if the conference does
not have content channel video
enabled, or if the endpoint has
no content capabilities.
You may change whether the
MCU is prepared to send the
conference content channel
stream to an endpoint using
content using the enable or
disable control here. If sending of
content video to an endpoint is
currently not allowed, you will
see the enable option, otherwise
you will see the disable option.
For more information about using
content, refer to Content
channel video support.
