The DIGISAT project is developing the required equipment and associated technology to ensure the incorporation of Satellite Master Antenna Television (SMATV) systems in the new era of digital television and interactive services. The new Satellite Broadcasting services (non interactive, near interactive and interactive) as well as innovative concepts for the implementation of the return channel via satellite will allow to arrange operational trials with selective user groups in order to assess the feasibility of the new services and related network architectures from several points of view (technological, operational and economic). In order to build the required receiving infrastructure for SMATV installations, complete head-end units (including the transparent digital transmodulator, either complete or simplified) are being developed. A key analysis is being done to interconnect SMATV networks with community antenna television (CATV) systems. Audience data acquisition applications with real time capabilities are being analysed as very promising tools in the broadcasting marketing environment. Up to now the DIGISAT project has made the following achievements: integration of the SMATV technology configuring the different equipment for digital TV reception in collective antenna systems; a complete definition and implementation of the Advanced Broadcasting Services via satellite; the implementation of the first phase of trials (more than 600 people followed the trials, a greater success than expected was achieved); production of a DIGISAT reference model for the interactive system and a draft specification for the DIGISAT; development of a interactive system (the prototypes for the implementation of the return channel via satellite are on going); a wide contribution to the standardization bodies mainly in interactive systems and services.
