Within the above cooperation, four stays of three
months each have been carried out as follows:


Stays 1+2:

Two stays from TUI to IMT Uni
-
Neuchâtel from
April 1st to June 26, 2001

( Mr. Radu Cezar Matei and Mr.
Eugen Romeo Ghinea );


Stays 3+4:

Two stays from TUI to IMT Uni
-
Neuchâtel from
Sept. 2nd to Nov. 26, 2001

( Mr. Tiberiu Dinu Teodorescu
and Mr. Victor Andrei Maiorescu ).

This cooperation is explicitly connected to COST 276.

36

Future directions:


Improved multimedia information and data management methods,
content and knowledge metadata descriptors,


Agent architectures and technologies for agent communication and
agent mobility, data delivery and retrieval, and for system
management,


Individualised service platforms based on user interface
personalization,


New algorithms, architectures and system design that provide
special features required by personalised multimedia services,


Advanced methods for Signal, Video, speech and sound processing
and coding.


The Action is oriented towards long
-
term basic research while
recognising the iterative nature of developments in this field,
due to the rapid development cycles of new technology.

The major goal is to develop a vision of future application
possibilities.
