7
About our relationship with HW
• Started in 2000 • Result of a transition from satellite service• Deliver at least 30 hours of content a week• Variety of faculty skill levels
8
About the setup of our delivery system
• Up to 24 in-class students• 2 computers, one for instructor, one for
assistant
9
About the setup of our delivery system (cont)
• 3 streams originating from each classroom– Real Video @ 20 kbps– Real Audio Only– High bandwidth QuickTime @90 kbps
10
About the setup for our delivery system (cont.)
• Multiple video (VHS and DVD) and audio formats can be piped into the class
11
About the setup for our delivery system (cont.)
• Triple redundancy built in to the process– Live Classroom Archive– RM file stored on encoder– Tape archive of the class kept until the next
session
12
Where did we start?
• Homegrown System– Eliminates the need to log in twice– Eliminates anonymity
13
Where did we start? (Cont)
• Logs users as guest but uses their name from Campus Edition– To those in the room all users appear with first
name and last name
14
Where did we start (cont.)
• 2 Elements– Student script– Link to admin area for instructor
15
Issues With The Old System
• Forced Guest Access– Server is wide open as a result– Privacy– No real access control and security is an
issue
16
Issues With The Old System (Cont)
• Consent for people not in the class to view archives?
• Link from each CE course has to be manually edited to point to the correct room
17
The Power Link
• Version 3 Of the Power Link• Introduced Spring 2007• 5 sections
18
What we like
• People still login only once but now it’s not anonymous
• All users coming through Vista get an account created in Live Classroom
• Security and ACLs can be enforced – Access Control List (ACL): Who has access to
what
19
What we like (cont.)
• We are considering disabling guest access altogether once all our courses are moved over to Vista and the Power Link
• Most of the administration can be done directly through the Power Link
• Tidies things up
20
What we like (cont.)
• We can trust our power users to do more without breaking things :-)
• The integration with Vista is very tight• Upload material from my files in Vista to
Live Classroom directly
21
What we like (cont.)
• Publish archives directly from Vista • User Accounts and Rooms use different
IDs than our rooms created manually– Easier to identify
22
What we want to change
• User Accounts and Rooms use different IDs than our rooms created manually– We can’t choose the ID for the rooms or users– This is good but causes problems for our
assistants and staff when setting up encoders
23
What we want to change (cont.)
• The room name is the same as the name of the proxy tool in the Vista section
• The Room ID is fixed and can not be selected or created manually– Naming is difficult and this complicates
management
24
What we want to change (cont.)
• There is still stuff that needs to be done through the LC administration– Setting up the video on the branding frame– Any additional access has to be configured
through LC Admin
25
Issues that affect deployment of the Power Link
• Level of administrative work having to be done– We centralize the creation of all our LC
channels for a given semester.
26
Issues that affect deployment of t he Power link
• For the Power Link this means adding my Vista admin account to each course adding the Power Link and creating the room– We do not want faculty to do it
27
Issues that affect deployment of the Power Link (cont.)
• Vista accounts solely for HW access– Rather than complicating things for our
assistant we add an assistant account to all Vista courses
• Everyone logs in through Vista.
28
Issues that affect deployment of the Power Link (cont.)
– Assistant account must be instructor in Vista• This introduces a potential risk unless the assistant
are trained in Vista• Not likely to change, have to rely on our assistants
29
What we have learned
• It can be disconcerting and scary– Most of our pilot faculty were worried about
how it would change the way they use LC• This was not the case
30
What we have learned
• It makes us dependent on Vista for access to channels – Even more of priority to have a stable system– System had to be rebooted 20 minutes before
a Power Link – enabled class started. Scary thought
31
What we have learned (cont.)
• Additional Training is needed– For faculty at least to show them how things
are different and how they are the same– For staff to know how to assist faculty– For administrators to effectively manage the
system
• Look on the admin interface when things are not working
32
What we have learned (cont.)
• Some things are not intuitive– Prefix for the classes was not shown when the
channel was created– Had to look in the LC admin interface to get
the full channel ID in order to encode video to it
33
Where to next
• Moving all our Fall 2007 classes to use the Power Link– Consideration for our Modem Users
• How far in advance do we need to set everything up?
• How much does Live Classroom 5.0 changes the way we do things?
34
Where to next (cont.)
• Working with HW to improve the Power Link and our internal processes– Making product suggestions based on
experience
• Rinse and repeat
35
Credits
• Staff (Ann, Bill, Buzz and Stephen)• Assistants (Jared, Gene and Dylan)• Pilot faculty using Power Link (Cris
Guenter, Tony Waters, Sally Parker, Steve Kooch and Graham Thurgood)
