3.1 Introduction
All the partners were present. The agenda was presented. The coordinator
presented:
 History of SCREENS proposal
 EU CRAFT program general rules
 The goals of the project
 Short introduction of members of consortium

3.2 Presentations by the Partners
All the partners introduced themshelves. The expectations for the project
were presented by the partners.

Action 1.1 (ALL, ASAP). Send the presentations of the 1st project
meeting to the coordinator. After receiving them the coordinator send them

3.3 Rules of EU CRAFT project

The rules of the EU CRAFT project was presented by the coordinator.
The following topics were presented:
 EU and Consortium agreement status and contents
 Access rights
 Operational Structure
 Project budget, principle of costs
 Project follow up: timesheet, cost stement form
 Workpackages, deliverables

There were a discussion about the Project start date. It was agreed by the
partners that the Project start date is 1st of June. The project partners are
aware about the small risk that the start date is in the past before the
agreements have been not yet signed. The coordinator promised to send
the Consortium Agreement for signing after the project meeting. The
Scientific Officier from the European Commission has informed that the EU
Agreement will be sent approximately in the middle of June.

and functions was formed.

Action 1.6 (Skyvision, 28 Jun). Send QFD product chart to the partners

The following main features for the system were decided during the
meeting

Max. Resolution                         165 Mpixels/s, single link limit
                                    enables 1600 x 1200, 60 Hz (162 Ms/s)

Max. video transfer distance                       24 meters
Max number of PCs connected                            127
Cable topology                              tree with multiport hubs
The number of daisy chains                              20
Student unit on the table /                both, will be decided later
below table
Number of video channels            one channel commands for two masters
Audio                                       two analogue channels
Max unit cost / student                    target 95 € incl 5m cable
Max cost for the user interface                  Target 140 €

Action 1.7 (Skyvision, VTT, ASAP). Send the detailed list of modes
(resolution, frequencies), where the pixel resolution is below 165 Mpixels/s.
The list of modes specification should be purchased from VESA (www.vesa.org)


4.2 User Interface
Patrizio Pisani from Consorzio Rome Ricerche gave a presentation about
the technical issues for the user interface.

Systech pointed out that they like to have an interface also to their existing
user panels for a new system. Datim would also like to have an interface
from their software based user interface to the new system.

Action 1.8 (Systech, 15 Jul). Systech sends protocol commands used by
them to the coordinator as a base for specifying the network protocol
commands. The coordinator sends the commands to the partners.

It was agreed that a common command protocol between user interfaces
and the master unit will be developed. A differential pair will be reserved in
the system for commands. RS-485 data link will be utilised.



                                                                             4
Action 1.9 (Datainnovations, Avision, ASAP) Datainnovations and
Avision consider their main requirements for the user interface.


4.3 USB Transfer

Patrizio Pisani from CRR presented the ideas for transferring USB mouse
and USB keyboard data. The following topics were covered:
 USB data will be transferred in the same RS-485 data link than the
   commands of the system.
 A stackable (2) USB connector will be utilised.
 USB connector provides also the power (5V, 500mA). Therefore the
   maximum power consumption should be tried to keep below 5W (from 2
   USB ports). The USB transfer and video transfer parts will be physically
   in the same mechanical unit.

A detailed specification for USB mouse and keyboard transfer will be
written after system level specification.


4.4 Digital Video transfer

Jari Jolkkonen from Skyvision gave a presentation about the key issues for
specifying the digital video transfer system. There was a discussion about
the approriate connectors and cables for the DVI transfer. Three
connectors were presented (DVI, RJ-45 + CAT6cable, HDMI).
HDMI connector was not selected, because of:
 The locking is based on friction. The locking is not reliable enough for
   professional applications
 The HDMI standard is primarily designed for consumer electronics
   devices like for connecting DVD-player to a wide screen plasma or LCD
   display
 The price of the HDMI cables are at the moment quite expensive

Action 1.10 (Skyvision, 28 Jun). Send the connector interface
comparision chart to the partners

Jari Jolkkonen presented also the initial topology for connecting PCs to the
screens network. A tree topology will be used. Every student unit (as well
as teacher unit) will be connected to each other by simple cable
connection. Every unit has a digital video connections to own PC and to two
others. Additional hubs will will be used in the network (connection to 3
PCs or hubs).

Risto Mutanen from VTT presented available commercial circuits for
increasing the video transfer distance. The most promising circuit at the
moment is Maxim3815 circuit.



                                                                             5
There was a discussion abour upper level specification for digital video
transfer research. The following things were decided to include in the
digital video research tests:
 Both DVI and RJ-45 connectors will be tested
 The number of daisy chains is 20. => This means that 20 prototypes
   should be made
 The cble lengths 3, 5,10 and 20 meters will be used
 Grounding problems, if any

4.5 Other issues
 All the SMEs would like to include 2-channel analog audio support
 Mechanics issues will be discussed in the next meeting



5. Next Meeting

The next meeting place and time will be decided later, after the EU contract
and the Consortium Agreement are in force.
