Transporting computer imagery over IP networks

Bringing information to the display
• Network
– Client applications running locally on the Argus
controller, retrieving data from remote servers over
the network
– Web-based: browsers running on Argus, displaying
applications from remote web-servers
– Remote sessions: TSE, X11
– Screen scraping: Cottus, VNC
• Direct input – traditional solution
– Video and RGB framegrabbers

SCN – Feature Highlights
• Up to 1600x1200 @ 60Hz DVI and RGB input
• Unicast and Multicast streaming
• Hardware Decoding on Streaming Video Card
– One stream per card
• USB Keyboard and Mouse control
– Web interface
– Apollo 1.8 SR1
• PS/2 Keyboard and Mouse control as an option (SSR
required)
• Software Decoder with recording capabilities
– This component is still in alpha phase
– Availability: see roadmap presentation.
• Not an KVM product for server management

SCN - Benefits
Technical
• Hardware solution: no need to install/maintain drivers
• The Compression algorithm guarantees picture integrity.
– In I frame only lossless compression mode, each output frame
is an exact copy of one input frame
• Applicable for legacy systems
• Separate networks can be used (secure applications)
• No performance repercussions on host system
(unlike software-based solutions)

SCN – Benefits cont’d
Deployment cost
• No more need for separate AV distribution and switching
equipment
• Simplified cabling
• Reduced integration effort
• Leverage on existing Ethernet/IP knowledge
Flexibility
• Encode once, display anywhere
• Scalability and flexibility for future extensions
• Distributed design with possibility for redundancy

ABT - Details
• Purpose
– Provide a set of tools to objectively quantify performance.
– But use it for what it is worth. Hands-on is still the best test
– Work in progress
• Benchmarks
– Random red, green and blue rectangles
– Moving window
– Controlled simulation of real life applications (ATC map)
• Calculated values
– % of pixel change per frame
– Application frame rate
• Results
– Frame Rate versus % pixel changes or complexity of the
content
