Videoconferencing
Experience
Content, each company
views the same version of the
contract. When ABC Co. sends
their version of the contract, both
ABC Co. and XYZ Co. see it. If
XYZ sends their version of the
contract, both parties see it. The
entire group sees whatever is last
sent, always focused on a single
content source.
When a user selects content, the
content is seen on all content
displays including the local display
eliminating the need to select the
local preview button. This feature
simplifies content management.
of the contract. If ABC Co. sends
their version, XYZ Co. will view it.
If XYZ Co. then sends their version
of the contract, ABC Co. will view
the XYZ contract. Now XYZ Co. is
viewing ABC Co.’s version of the
contract and vice versa.
Participants are never sure what
the other location is viewing. The
group doesn’t have one contract
on which to focus at a time.
When the presenter sends content
to the far end, the near end
doesn’t see it unless the speaker
takes the added step of pressing
the near-end preview button.
Content is supported on Polycom’s VSX 7000, ViewStation EX/FX/VS4000 and iPower
videoconferencing endpoints, as well as MGC multipoint servers.
4.2. Video Compression
Video compression is a critical technological component of videoconferencing. Under Content, VSX
7000 systems use different priorities for handling people video versus content video. The general rule is to focus
on motion for people and to focus on resolution for content.
The following table describes the protocols used for video compression on the systems:
