  1. How FERNE Uses the Internet:The How’s and Why’s of Videostreaming

  2. Adam Schlichting Research Associate Department of Emergency Medicine University of Illinois at Chicago Associate Director

  3. The “Case” • This meeting is being recorded on a digital video camera • Videostreaming will allow these lectures to be accessed 24/7 from anywhere in the world • How is this done???

  4. Why Videostream? • Educational lectures can be viewed: • Anytime • Anywhere • By anyone with a computer

  5. What Equipment Is Necessary? • Video camera (digital or analog) • Fast computer with: • An audio/video capture card • Lots of storage • Lots of memory

  6. FERNE Equipment:The Camera • Canon XL1 DV Camera • Excellent sound, excellent picture

  7. FERNE Equipment:The Server • Why buy our own server? • Speed • Needed a computer with fast processor, lots of memory for videostreaming • Storage • Videostreamed files are big: 20 Mb • Intermediate files are huge: > 1 Gb • Cost of off-site server • About $20/month for 100 Mb

  8. FERNE Equipment:The Server • Dell PowerEdge 1400 • Osprey Video capture card • Audio card

  9. FERNE Equipment:The Server • Osprey Video capture card • RCA inputs, same as the back of your TV, VCR • Good audio card • Standard in computers, not in servers

  10. FERNE Equipment:The Software • Microsoft VIDCAP32 • Video Capture Tool • Intermediate step • (Package deal: Osprey video capture) • Capture from camera playback • Saves as *.avi • Import *.avi into Premiere for editing

  11. FERNE Equipment:The Software • Video Editing • Adobe Premiere • Professional video editing software • Mouse driven • Cut/Paste • Crop • Drag/drop • Possible to capture directly from camera, import all standard audio/video file formats

  12. Thus Far… • Ability to record audio/video • Edit audio/video • Export as standard media: • avi • mpg • pic • wav • MP3

  13. Storage Issues • *.avi or *.mpg files are big • 20 minutes is > 1 Gb • Entire file must be downloaded onto viewer’s computer to watch • Multiple hours • Necessary to condense

  14. Videostreaming • Progressive downloads: • Video files must be downloaded somewhere on the viewer's computer in order to play • Streaming video: • Arrives to the viewer in "real time“ • Viewer doesn’t have to wait for it to download before being able to view it • Jump to different areas within video • Dynamically adjusts to Internet conditions

  15. Videostreaming Formats • Several options available More PC Based More Mac Based

  16. The Choice • I’m a PC Guy • Before I came on board: • First FERNE course was videostreamed using Real by University of Virginia via FERNE Board Member Stephen Huff • Subsequent FERNE courses videostreamed at University of Illinois at Chicago • Center for the Advancement of Distance Education (CADE) videostreaming lab

  17. Real • RealPlayer • New version = RealOne • Available for free: http://www.real.com • Link to download from FERNE webpages

  18. RealSystem Software • RealSystem Producer • Software that allows conversion of audio/video into RealMedia formats for streaming • RealSystem Server • Software that allows media streaming media to be hosted on server, live or on-demand

  19. Target Audience • Specify connections of anticipated target audience for best compression • Create multiple files for up to 8 different connection speeds • Encode (and link) to single file • RealSystem optimizes each viewer’s connection

  20. Example 1 Streaming of Audio and Video

  21. Thus Far… • Ability to record audio/video • Edit audio/video • Export as streaming media • Who wants to watch a video of someone talking for 20-30 minutes?

  22. Syncing Audio With Slides • RealPresenter Plus • Allows for narrating MS PowerPoint shows • Add-in to MS PowerPoint • Intended for use with microphone • We “trick” it using audio input from camera • Watch video for timing of when to change slide

  23. Features • Fast-forward • Pause • Allows viewers to jump to: • Desired slides • Desired time

  24. Example 2 Streaming of PowerPoint Slides with Audio

  25. FERNE Links • Web pages on a server in Jupiter, FL • http://www.FERNE.org • 100 Mb storage • Links to our local server for large files • PowerPoint shows • PDF files • Videostreamed content • http://ferne.er.uic.edu:8080/ramgen/

  26. Making Files Play Automatically • So RealPlayer automatically opens: • Insert /ramgen/ into link
