Defining People Video Quality
To define the video quality of CP conference:
As described in the table below, select the highest resolution of CP
conference in the People Video Definition field.
Table 4-5 People Video Definition
Parameter Description
Up to H.264,
CIF/SIF
It is used for the screen display of ordinary quality. The
conference video can be best encoded/decoded with the H.264
protocol and displayed with the CIF/SIF resolution, requesting
the lowest bandwidth requirement and occupying the minimum
system resources. In the conference, each endpoint only
occupies one video connection resource.
Up to H.263,
4CIF/4SIF, 15FPS
It is used for the screen display of high quality. The conference
video is encoded / decoded with the H.263 protocol and
displayed with the 4CIF/4SIF resolution and 15FPS frequency,
requesting a higher bandwidth. In the conference, each
endpoint only occupies one video connection resource.
Up to H.264,
4CIF/4SIF
It is used for the screen display of higher quality. The
conference video is encoded/decoded with the H.264 protocol
and displayed with the 4CIF/4SIF resolution. The endpoint
must support the H.264 protocol and the bandwidth cannot be
lower than 256Kbps. Each endpoint in the conference utilizes 2
video connection resources.
(Optional with
keycode) Up to
H.264, 720P
(Common Layout)
The conference video can be best encoded/decoded with the
H.264 protocol and displayed with 1280x720 (720p) HD
resolution, utilizing more system resources. The conference
under this mode has the following restrictions:
ƒ
The endpoint must support the H.264 protocol and 720p
resolution, and the bandwidth cannot be lower than 832Kbps.
Otherwise, the conference video will be degraded to the
4CIF/CIF resolution display or H.263 coding depending on
the capability of the endpoint that joins in the conference.
ƒ It supports only the Same Layout video mode, and the same
video layout is displayed for all the conference sites.
ƒ When there is no other CP conference concurred, the system
supports convening a maximum of 5 720p conferences at
the same time on condition that each conference only has
two participants and they all support 720p.
ƒ
When a 720p conference is ongoing, the screen of the
participant’s endpoint displays only the conference video. For
the PCM related information, see Personal Conference
Manager (PCM).
Note: Up to H.264, 720P
is an optional function of the RMX
1000 and will not be available until a license is purchased. If the
license for this function is not activated, the device does not
display the related options. To obtain this function, please
contact your supplier.
To define the video quality of video switching conference:
Select Video Switching Highest Common from the People Video Definition
field.
Each endpoint under this mode occupies only one video connection resource,
