RETAIN - Radiological Examination Transfer on ATM Integrated Network

Teleworking Application

Rennes (F) - Barcelona (E) using ATM terminal adaptor
The teleworking application allows the physicians to manipulate data (examinations, series, images) on both sides during the discussion, through the use of groupware tools. Four "kinds" of interactions are allowed:

local, with no remote effect;
with validation, for which the remote site is modified only after the validation;
direct, sent to the remote site;
with mutual effect on both sites, differentiated by colours (cursor, graphical and textual annotation);
The master/slave model is never used, so any site can interact at any moment. The application is structured to have no conflict of state on data. The original data is stored at the two sites, so that conflict in database is avoided.

High quality video conference - Teleworking workstation with synchronization

In this experiment ATM and ISDN where linked (audio & video) in Rennes (F) allowing a consultation session betwen Barcelona (E), Rennes (F) and Oldenburg (D). The link was done: Barcelona (E) <--ATM 34 Mb/s --> Rennes (F) <--ISDN 384 kb/s--> Oldenburg (D).
