PCoIP Technology User Guide (Vol I)

1 PCoIP Technology

Overview

The PCoIP Technology solution provides a no

compromise method to remote a user's desktop

over an existing IP network. This functionality

includes full DVI dual monitor video, complete

USB compatibility, and full-duplex high definition

audio.

Figure 1: PCoIP System

Teradici's PCoIP Technology uses networking

and proprietary encoding/ decoding technology

to remote connections between the Host

PC/Workstation and Portal via a standard IP-

network. Using a PCoIP Technology remote

connection, a user can operate the host PC and

use the desktop peripherals as if the host PC

were local.

PCoIP Host Processor

The PCoIP Host Processor connects into the

host PC or workstation via the digital video

interface (DVI) and PCIe bus. The pixels from

the video interface are encoded and sent to the

Portal. The PCIe bus connection provides

transparent bridging of USB peripherals and HD

Audio using the standard USB and audio drivers

provided by the OS.

Prior to transmission, the PCoIP Host Processor

compresses the video stream and combines the

bridged audio and USB traffic.

PCoIP Portal Processor

At the desktop, the PCoIP Portal Processor

decompresses and distributes the video, audio

and USB data. In the return path, the PCoIP

Portal Processor combines audio and USB

peripheral data, for transmission back to the

Host.

This process of compression, transmission, and

rebuilding the desktop occurs in a very short

time, typically less than one display frame

update, to ensure desktop responsiveness.

A PCoIP Portal can be a desktop device or be

integrated into a monitor.

Operating Systems and Applications

The following summarizes Operating System

and Application compatibility:

• PCoIP Technology is operating system

unaware

• Extensively tested with Windows

Windows Vista

(32-bit)

• PCoIP Technology does not require special

drivers to be installed and uses standard USB

and HD Audio device drivers

• PCoIP Technology is compatible with all PC

applications as no hardware or OS changes

are required in the host PC

Display

PCoIP Technology display attributes are:

• Provides a 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

Related PCoIP Technology networking points

are summarized:

• Uses existing IP network and co-exists with

existing IP data

• PCoIP Technology optimizes the user

experience for a given bandwidth by

adaptively controlling quality and update rate

of the image data, and optionally compressing

the audio stream

• PCoIP Technology will adapt to changing

network environments and use less bandwidth

when network congestion is present

• PCoIP Systems can be optimized towards

minimal bandwidth usage for lower bandwidth

situations, e.g. corporate WAN

and
