Robotic PTZ Video Cameras

• Two fixed cameras at the north and south ends of
  lab
• Two wireless cameras for experiment-specific
  viewing
• Pan, tilt, and zoom controlled from telepresence
  portal
• Video streams can be routed to Data Turbine
  server and viewed with the Real-time Data Viewer
  (RDV)
• Up to 10 frames/second at 640x480 pixels

6
Robotic Still Image Cameras

• Three Olympus C750 4.0 megapixel cameras on
  robotic pan/tilt bases
• Controlled via LabVIEW GUI or web interface
• Captured images fed into Data Turbine for viewing
  with RDV
• Used for remotely viewing fine detail at low
  frame rates (10 seconds/frame)

7
MiniDV Camera

• Canon GL2 Three CCD digital video camcorder with
  16-bit stereo sound
• Captured video edited and reformatted with
  open-source video tools (Kino, MJPEG Tools)
• Reduced quality video can be streamed to Data
  Turbine in real time

Local Data Management

• Data is moved from data sources to local data
  repository via network file system
• Data from Data Turbine acquired with data sink
  tools
• Local repository stored on redundant disk array
  with automatic tape backup
• Data manually uploaded to NEES Central
• Metadata manually uploaded to NEES Central

Data Turbine

• Numeric and image data is fed into the Ring
  Buffered Network Bus (RBNB) Data Turbine
• Data Turbine is responsible for collecting and
  synchronizing data from data sources
• Synchronized data is streamed to Real-time Data
  Viewer (RDV) clients
• Synchronized data is also streamed to disk for
  later access

13
RDV

• Used to view real-time, streaming data over a
  network from a Data Turbine Server
• Instant Replay functionality with variable
  speed playback
• Synchronizes numeric, video, and still image data
• Allows user to overlay data from local PC onto
  streamed data
• Developed by Buffalo NEES equipment site

FlexTPS

• Allows remote viewing and robotic control of live
  video over the internet using only a standard web
  browser
• Digital Video Recorder (DVR) functionality allows
  video streams to be recorded and played back
• Collaboration function allows video streams from
  local site and other NEES sites to be viewed
  together
• Developed by University of Texas, Austin
  equipment site
