Overview
PC-over-IP
®
(or PCoIP
®
) Technology is
designed to deliver a user’s desktop from a
centralized host PC with an immaculate,
uncompromised end-user experience across
standard IP networks; including full DVI dual
monitor video, complete USB compatibility, and
high-definition audio.
PCoIP Technology makes it possible to locate
the PC or workstation hardware in the
datacenter while continuing to give users full
desktop performance.
Figure 1-1: PCoIP System
PCoIP Technology uses networking and
proprietary encoding/decoding technology to
allow remoting of the host PC or Workstation.
Using the desktop Portal, desktop peripherals
can be used normally, as if they were connected
directly to the host PC or Workstation.
PCoIP Host
The PCoIP PCIe Host card is installed in the
remote host PC. The DVI output is connected to
the Host card where the DVI output is
compressed. The Host card PCIe bus
connection provides transparent bridging of USB
and HD audio using standard USB and audio
drivers.
PCoIP Portal
At the desktop, the PCoIP Portal decompresses
and distributes video, audio and USB data. The
PCoIP Portal combines audio and USB
peripheral data for transmission back to the
Host.
To ensure desktop responsiveness, the process
of compression, transmission, and rebuilding
happens very quickly
−
typically in less than one
display frame update.
A PCoIP Portal can be a standalone desktop
device, or be integrated into a monitor.
OS and Application Compatibility
•
Compatible with all operating systems
•
Extensively tested with Microsoft Windows
®
XP
®
and Windows Vista
®
•
Uses standard USB and HD audio device
drivers
•
Compatible with all PC applications as no
hardware or OS changes are required in the
host PC
Display
•
Perception-free experience with low latency,
full frame rate video for the same user
experience as a local PC
•
Progressive build to deliver exact image of the
rendered host display
Network
•
Uses existing IP networks and coexists with
existing IP data
•
Optimizes user experience for a given
bandwidth by adaptively controlling image
data quality and update rate and optionally
compressing the audio stream
•
Adapts to changing network conditions and
uses less bandwidth when the network is
congested
•
Can be optimized for minimal bandwidth
usage for lower bandwidth situations (e.g.
corporate WAN)
Input/Output
•
Fully-bridged USB for all USB devices
(including USB2.0 at USB1.1 data rates)
•
Bi-directional, multi-channel digital audio
