Additional Video Conference Types
Video conference settings can include additional features, for example to
increase the number of participants in a single conference or to allow
application sharing during the conference.
Conference On Port (COP)
In a Conference On Port, all participants use a single video port for the
conference. This enables the selection of a video layout for the conference but
all the participants, including the speaker, view the same layout and the same
participants. Personal layout selection is not available in COP and the video
quality is determined by the highest common video parameters and by the
video line rate.
In order to maintain a minimum video quality for a Conference On Port, there
is a minimum threshold line rate that participants must support in order to
connect with video. This minimum threshold line rate is determined
according to the conference Line Rate. For example, in a conference defined
with a Line Rate of 768 Kbps, a participant with a line rate of 128 Kbps will
connect as Secondary (Audio Only), in order to preserve the video quality of
the conference.
The minimum line rates necessary to connect to a Conference On Port are
listed in Table 4-1. Participants attempting to connect at rates below the
minimum threshold are connected as Secondary (Audio Only).
