Sat-n-Surf aims to take the results of Sat@Once, a previous ARTES-3 project, and bring it additional tools and the means to become a full-sized new broadcasting medium on par with popular radio or television.Sat@Once
developed a satellite webcasting technology, called Casablanca, to distribute the best of the Internet to all DVB-Data receivers under the flagship of SES ASTRA.
Casablanca is a technology that takes advantage of the strong value of satellite transmission, which is broadcasting. It sends the same transmission to all listeners. This approach is the opposite to the familiar point-to-point approach (unicast) of the Internet, where data goes from one source to only one destination.
Taking advantage of the huge satellite capacity, Casablanca acts as a "virtual matchmaker". On the local PC of the user it runs a "Magic Mirror" that matches together the personal interests of any given user and profiles of the content that is sent by satellite. In other words, the Magic Mirror "catches" all the information of the day that may be of interest to his master.
Casablanca is attractive both to the end-user and to the Content Provider: the user keeps the privacy of his preferences, while the Content Provider is guaranteed that his message will reach those that are interested in it. A message can be information, entertainment or advertisement, and may be pre-existing on the Web or specially created for broadcasting. It reaches its target population "automagically".
