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
LOGO
Webcast & Recording• Live webcasts / Recordings• Streaming for on-demand videos (hosted on
CDS)• 16 rooms equipped at CERN

Recorded lectures (+17%)
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
LOGO
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

Created Indico events (+13%)
Indico at CERN• User satisfaction survey
Indico• Ongoing transition away from ZODB and to
PostgreSQL (using abstraction layer SQLAlchemy)• Release 2.0 foreseen end 2015
• Better integration with collaboration services• Better plugin management• New e-payments options (bank transfer and
EUR/CHF for CERN)• Rich abstract editor (LaTeX/Markdown)• E-tickets
LOGO
Indico Outside CERN• 164 institutes have an Indico server
worldwide
LOGO
Indico Distribution• KT project #1 (2013-15)
• New visual identity• New web site / video• Instance tracking feature• Cloud deployment scripts
Indico Global Service• KT project #2 (starting 2015)
• Supporting communities in Indico

Common Frameworks• All software packages developed by the
services• Are published under a GPL v3 licence.• Use git / github / gitlab for version control• Use Jira / github for task management• Use/have plans to use the Wigner computer
center resources for business continuity solution.
