Specification of the 3rd trial LEVERAGE system: Deliverable DWP921
A zipped version of this document can be downloaded here.
Abstract :
This document includes the functional specification of the following LEVERAGE subsystems:
- Session Management, which deals with the management of cooperative sessions and all the resources used during synchronous cooperative communications.
- Data Conferencing, which includes all the shared applications that will be used during point to point and multipoint cooperative sessions in order to share documents between participants.
- Media Player, which plays audio and video sequences possibly concurrently with on-going videoconference on LEVERAGE workstations.
- Video Conference Application, which manages the videoconference on each LEVERAGE workstation.
- Multipoint Control Unit, which manages, on a server, the conference between conventional conferencing terminals.
- Administration and system tools, which concerns the administrative server and tools available on it to provide applications working on users workstations with system and administrative functionality.
- Material tools, which includes the WebComplex dictionary, help module, material preparation tools and evaluation system.
