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

Want to connect a PC over the LAN?

Put a universal decoder card in the Argus/Hydra

Install a TransForm SCN at the PCHook it up to the networkConnect it in between the PC and its monitor on analog or digital DVI

Configure it from any PC on the network with a standard Web browserYou’re up and running !

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)

Page 12

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
