3. What I t L oks L ike
o
s Gilligan example
s RealVideo streaming video usually
requires at least a 56K connection.
s One can decide how much bandwidth is
devoted to video and how much is
allocated to audio.
– Recommendation: Devote more bandwidth to
audio, less to video.

s Allows virtual observers and eventually
virtual participants at conferences.
– Allows many to attend who otherwise
would have been unable to do so.
– Programs:
• RealVideo: Broadcast only
• NetShow Broadcast only
• NetMeeting Interactive, limited multipoint

s For readers, it is often helpful to
associate a face and a voice with an
author that they are reading.
s Instructors can assign video or audio
just as they would assign reading
assignments
s Good conference interactions are not
lost forever.

6. H o to do it
w
s Obtain permissions
s Record event
s Capture
s Encode recording
s Place encoded file on server
s Stream video
Record Capture Encode
Upload Stream

7. Obtain pe issio
rm ns
s Even if you hold an existing permission,
obtain an additional one for the web.
s Permissions should be non-exclusive,
allowing lecturers to use material
elsewhere.

8. R e rd e e
co v nt
s Recording events simply requires
standard videotaping
– The better the quality of the recording, the
better the web-based result
– Use super-VHS if possible
s High quality digital recording is even
more flexible
s Always pay attention to sound quality

9. Capturing
s The event needs to be captured on the
computer before it can be encoded.
– Audio: only requirement is a sound card
– Video: also need a video capture card
• Windows: Osprey 100--cheap, reliable, Win95
& NT compatible, and recognized by
RealPublisher. $129.00

10. Enco re rding
de co
s You can begin with video or audio
recordings not originally intended for
the Web.
s Use RealPublisher. It’s cheap and it
will:
– capture (live or from tape or file);
– encode (using convenient templates);
– publish as html.

11. Place e de file o se e
nco d n rv r
s In the past, you had to use a RealServer
to have streaming audio and video.
– Any server will deliver RealVideo and
RealAudio that can be downloaded first and
then player.
– New versions--including the G2--now stream
without RealServer; .
s Both RealPlayer and basic RealServer
are free.
– Note: RealServer cannot be used free of
charge to broadcast courses.

12. S tre v o
am ide
s Basic, free RealServer will stream video
to 40 connections simultaneously.
s Viewers only need the free version of
RealPlayer and a reasonably good
internet connection (56K) to view the
video.

adcasting A nim ns
atio
s It is also increasingly easy to broadcast
animations over the web. Currently,
Macromedia offers the best format in its
Flash files:
– Euthanasia example
s Streaming animations offer powerful
ways of communicating visual
knowledge over the Web
s Very small file size (17K), streaming,
vector graphics

17. H ardw R e u mnts:
are q ire e
Enco ding
s Video camera (for live) or tape (for
archival)
s Video capture card
s Fast CPU (200 Megahertz Pentium
minimum; dual Pentium Pro 200
preferred)
s Adequate disk space (1 gig free)

18. H ardw R e u mnts:
are q ire e
Se e
rv r
s Fast server with plenty of RAM
s Adequate disk space
– 10-12 MB plus per hour for 56K
• at $100 per gig, this is about $1 per hour for the
cost of disk storage space
