Agenda

Isn’t the written word enough?

Historical view of Video
communication for commercial
use


Extending the reach of
teaching and learning
techniques today by “clever”
use of the Internet.
Empirical Evidence !
Origin of the species
Sharing of knowledge base
Ability to share
information through
technology
Communication techniques
evolving
Time
The 4 semi-permeable membranes(aka recall)
Text – 25-45% 1st time retention
Audio – 35-55% 1st time retention
Visual – 45-55% 1st time retention
Audio/Visual – 55-75% 1st time retention
[Audio/Visual/Practical – 85-95% 1st time retention!!]
“I see what you are saying but…………..”
Human nature to be short sighted and resistant to change?
“This ‘telephone’ has too many shortcomings
to be seriously considered as a means of
communication.”
“The device is inherently of no value to us.”
Western Union internal memo, 1876
But of course eventually……
The Telephone System Happened
“Should have done this years ago !”

infrastructure before e-learning is enabled (i before e!)
The foundation of communication is infrastructure (i)
Point to Point (1 to 1 communication)
H.320
ISDN
H.320
Multipoint (1 to many, or many to many)
H.320
ISDN (bridged)
H.320
Used by the those who afford the high cost of entry:
1. Expensive end systems (£20,000-£50,000)
2. Early systems supported Basic Rate ISDN (128Kbps)
3. Unreliable (Operating system based, eg. OS/2)
4. High cost of ISDN, especially internationally
5. Low Quality

The foundation of communication is infrastructure (i)
Quality of ISDN improves and ATM arrives
H.320
ISDN (up to 384Kbps)
H.320
25Mbps ATM
Gateways between ISDN
(H320) and ATM (H321)
ATM Private and
Public networks
arrive
H.321
155Mbps ATM
34Mbps ATM
Speeds now upto 384kbps for
ISDN and ATM systems now able
to use MPEG1 OR MPEG2
(>8Mbps)
H.321
25Mbps ATM
622Mbps ATM

Quality/Class of
service enabled and
H323 aware gateways
and firewalls now
being produced by
Cisco
Legacy systems
still in place.
Needing to
“transcode”
between H320 and
now H323 to talk
to IP based devices
Internet
H.320
H.320
ISDN (up to 384Kbps)
25Mbps ATM
ATM Private and
Public networks
arrive
H.321
“Another network to manage, but
this one is
bigger than rest put together !
That’s no good !
Gateways between ISDN (H320) and
ATM (H321)
H.321
Speeds now upto 384kbps for ISDN and
ATM systems now able to use MPEG1 OR

We still have to contend with the Big “i”
The Internet (QOS/COS
getting better)
LAN/MAN
Edge

Your campus LAN/MAN,
QOS/COS enabled
Edge

H323 Everywhere (so “i” is now sorted !)
Internet
“Fine, but how do we manage such a distributed, abstract thing based on
the Internet, as well as all the features that the old systems gave us???”

Management of a converged network environment
Cisco AVVID partner programme
Internet
“It would really useful if this could all be done from a browser for ease of use…”
Enter -
(the “e” enabler)
 Web Data Collaboration (sharing of applications and
content)
 Business quality desktop video (to suit the application)
 Integrated into how you work today (web based)
 Instant Messaging (Chat , whiteboards etc..)
 Streaming (live and stored)
 Ad-hoc and Scheduled Conferencing
 Control
 Simplicity
 Inclusion of legacy systems
 Works seamlessly with Cisco video solutions
(gateways, MCU’s etc)
“Now we are getting somewhere, tell me more”
Benefits
- designed for use by students, pupils & users
 No User Training Required!
 Ease of Use as a guiding principle
• Multiple ways to do things
• Non-essential items at a lower level
• Many functions automatically handled by system
 User profile tailored to the individual
 At a glance view of current activities and information
 Presence indication
 Multiple locations and user mobility
 Delegates and guests
 Public meetings
“Sounds to easy to me, does it exist? What does it look like?”

So what does an E2B video room look like?
Codec (Camera and
Microphone
with built in
Network
Connection) or
desktop system
User’s pc being
used for data
sharing (could be a
personal laptop)
Monitor (TV or
Wall or Ceiling
mounted Plasma
screen or pc screen)
Controls (remote /
mouse/keyboard if
req’d)
Local Area Network
Connection
Video call (point to point or
multipoint enabled via PC onto
the CRUK Click to Meet URL.
Think About your environment !!
1.
White walls and bright lights degrade the quality of the image
2. Loud ties and white shirts should be kept to a minimum !
3. Camera’s should not be pointed at direct light sources
4. Keep you microphones away from noise sources
Summary
IP infrastructures can be created to provide
usable converged voice, video & data networks
that are accessible to all
They can be managed and use the resources that
often already exists (data network and internet
access)
The video solutions now use efficient protocols
that will give you reasonable quality that is
affordable
The ability to provide more stimulating
content direct to the end user now exists –
After all it is all about content!
And Finally….
It’s all about Strategic Vision
“Who the hell wants to hear actors talk ?”
HM Warner, Warner Bros., 1927
“I think that there is a world market for maybe
five computers.”
Thomas Watson Chairman of IBM, 1943
