Conference Rooms• InforEAM
• Equipment inventory and tracking• Maintenance tracking
Conference Rooms• Extron GVE
• AV equipment monitoring, alerts, automated actions
Conference Rooms• RAVEM (Room AV Equipment Manager)
• Centralised equipment control• Python, Django, MySQL (DBonDemand)
• Examples:• Proxying rooms
connections to Vidyo• Switching “on-air”
signs
Conference Rooms• Service dashboard (http://avc-dashboard.cern.ch )
• User/customer facing status interface• Drupal, Google charts, HighCharts
Conference Rooms• Security
• Networked devices: projectors, controllers, PCs etc.
• Access protection mandatory
• Wireless communication encryption• End user protection
• Subtle simplicity/security ratio• Ex.: on-air signs in the VC rooms

Conference Rooms What’s Next ?
• Investigating wireless data transmission• Bluetooth, wifi• Proprietary protocols (EPSON QuickConnect,
INTEL WiDi)• Lack of standard, but some ongoing
consolidation
• More remote controls and monitoring options
• Online physical locks for meeting rooms

Video Workflow• Submission of video clips to CDS
• Ingest from web upload, DFS hot folder, Vidyo recording; transcoding; browsing
Webcast What’s Next ?• Improved subtitling options (separate
subtitles file)• A webcast web site for mobiles• Towards new streaming standards
• mpeg-dash: adaptive bitrate streaming over http• to reconcile desktop and mobile viewing
• Central operation center• Currently each room has its own control
interface

Vidyo• Multiplatform videoconferencing service
• Desktops (linux, Mac, windows), mobiles (iOS, Android), phones, H323

Vidyo News• Recording feature in
production
• Service monitoring (CERN development)
Vidyo News• VidyoWeb for guests• (MacOS and Windows)
• New router in South Africa• Deploy SSO and Lync gateway• Vidyo replaces Alcatel MyTeamWork as official CERN
audio conference service
Vidyo What’s Next ?• Ongoing discussions with GEANT to
propose a service to worldwide research and education based on CERN infrastructure.
• Using VidyoRoom hardware in CERN meeting rooms instead of H323 devices?
• WebRTC• Interesting emerging standard for embedding VC
in the web browser• Vidyo to come up with a dev kit to build
dedicated clients (a solution to Linux issues?)
Indico• Event organisation and archiving system• At CERN
• 331000 events
