This deliverable describes the user applications of the second trial, their functionality, usage scenarios, and support by the End-user Application Toolkit (EAT).

"This deliverable describes the functionality offered to the user of the second trial. It takes into account experiences from the experimental integration carried out in the first trial phase. It is explained how the use of the generic End-User Application Toolkit makes the production of application software more controllable and economic. Technical details on the End-User Application toolkit are not covered here but in deliverables D2201 and D2203. Target audi-ence for this deliverable are people deciding on the actual external appearance of the trial to the end-user, including representatives of the end-user community." [Technical Annex]

D2204 is the continuation of D2202. Whereas D2202 describes the user applications of the first trial which were Basic Internet Applications (BIA), D2204 focuses on the issue of so-called Complex Internet Services (CIS). CIS bind existing BIAs to a new, value-added service with QoS support.

The CIS for the second trial is Mediazine. It bundles several Basic Internet Applications to some extent already known from the first trial: RealSystem, NetMeeting, and the interactive game OIDS.

The CIS Mediazine is the main issue of D2204 and is described in detail (functionality, screen shots, usage scenarios) within this document. Like in D2202, the deliverable also contains the QoS requirements and the appropriate Application Profiles for Mediazine.

Moreover, D2204 also presents SIGMA, based on SIP, which is another application for the second trial. In this manner it is possible to demonstrate further advanced functionality of the EAT for the second trial: The EAT transparently supports standardized signalling protocols such as SIP used by many upcoming Internet applications (VoIP, etc.).
