Agenda• What does it mean to be virtual

and digital?• What do the scientists need to feel

comfortable in their work?• What does it mean to learn and

can the learning process be improved (pragmatic approach)?

Future is not what it used to be...

• Computers used to be used for calculations (very small user base, mostly scientists).

• Computers started to be used for turning information to knowledge (PC age).

• Computers are used for communication (the age of masses).

Future

• Wireless (we all move, don’t we)• Virtual (life is converting to bits)• Personal digital assistants (PDA)• Personal agents to turn information

into knowledge• Information, knowledge and learning

will be delivered from the same kiosk

Combining information, knowledge & learning

• Information ecology– survival of information and media

• Knowledge– sustained archives/digital preservation

• Learning landscapes– flexible and intuitive learning environments

• Information and knowledge are human creations

Virtual

• University, combining research and educational resources

• Laboratory, combining research resources and equipments

• Library, combining the knowledge resources

to be used over the global network!

Characteristics of a virtual world

• Geography, the metaphor of connected places.

• Identity, the way we present ourselves.• Communication and awareness

mechanism to suit styles and groupings.• Community, to develop for the

Take as an example DigiTV

• A multiplex of channels– 4 – 5 digital channels– Uses about 30 Mbps

• The interactive services are not yet very well defined not to mention the implementation.

• Very few terminals to receive the broadcast available.

Academic networks

• n * 155 Mbps connections both national and international.

• Networks Multicast enabled at least USA – Europe (needs still improvements).

• Lots of H.261/MPEG-1 terminals available.• Universities have a lot of content but can it

be turned into useful material?

• FUNET-TV is the joint development project of CSC and the Finnish Universities. Its purpose is to produce Internet networked multimedia services to the Funet network, that support the research, study and learning in the Finnish universities.

• FUNET TV contains the following services: – transmission of live video – transmission of video conferences – video on demand (VoD) material that has been

stored in the media archives – storage for digital material

FUNET-TV is an effort to combine

• real time video broadcasting (RealMedia, H.261, MPEG-1, MPEG-2) using an IP network,

• high quality videoconferencing (H.261, H.323, MPEG-2) over IP and

• video on demand, VoD, (MPEG-1, MPEG-2) including storage for digital material

to everybody’s desk.

VRVS @Caltech with CERNVersion 2.5 in production in Fall 2000: • Mbone clients and H.323 clients in the same

Virtual Room • Sharing of desktop service (integration of VNC) • Remote control of video camera • User can choose his reflector when is machine

is not registered in the Domain Name Service • The VRVS profile is automatically re-

synchronized when a laptop is connected from another location

• One new MPEG2 Virtual Room

Would it be possible to• agree on a science video portal

including live lectures, seminars and conferences

• build a science video on demand service using metadata

• support interactive video conferencing over country and discipline borders

@Le

continue...

• a scientific interactive digital TV channel (not just a digital version of the current analog TV world)

• get people interested in content creation

• solve the involved copyright issues

Problems involved

• Multicast networks are not very reliable (no performance problems).

• Very few good Multicast clients available, even less free clients.

• Problems with the Multicast implementation of MPEG-1 (I-TV and IP/TV).

• What are the extra services added to video/audio?

• We are competing for the same prime time as for example MusicTV does.
