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 IPnetwork. 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.

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® XP® and 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 © 2008 Teradici Corporation Page 3 of 25
