BRIEF DESCRIPTION OF THE PROJECT
The REPOSIT project defined, developed, implemented, demonstrated and validated a spectrum efficient interactive satellite (DVB-S) network, using real time dynamic management of the available bandwidth, for supporting a variety of heterogeneous bit rate services, like interactive TV, Internet and multimedia applications. The network was used for the interconnection of terrestrial distribution nodes and has been tested over an existing regenerative satellite. Both downlink and uplink were based on DVB-S technology. The network used spectrum in an efficient way, due to a bandwidth manager in the terrestrial segment which adapts the capacities dynamically and in real time according to the services and end-users requirements and the available network resources. The validation of the REPOSIT project was achieved through field trials using three characteristic types of terrestrial networks: DVB-T, WLAN and xDSL.
GIT contribution to this project consisted on the development of a Service Customisation Module (SCM) located in the interface between the end-user and the Dynamic Bandwidth Management System. The main objective of this SCM was to provide an access control checking the user profile which describes the set of services subscribed. Additionally GIT provided and adapted a WEB based Tele-learning tool with contained different types of services ranging from traditional FTP and WEB service up to remote access to network design and simulation tools.
