Abstract: The invention relates to a receiver [STB] intended to process at least one content [p] sent by a transmission station over a netowrk [NET] including transportation channels configured for transporting said content, characterized in that it can be connected during so-called supply events on a so-called program channel [PGC] belonging to said network [NET]. The program transportation channel [PGC] conveys according to the invention at least one content [P(SW)] including at least one software programs [SW], intended to control the receiver, coded and in a loop. The receiver [STB] is connected [CNX] to said program channel [PGC], reads and decodes [DEC] and stores said software program [SW] in a volatile memory [VME]. Control means [CNT] controlled by a so-called supply program [SPG] stored in a non-volatile memory [NVM] control the connection [CNX] of the receiver [STB] to the program channel [PGC], the reading and decoding [DEC] and the storing [STR] of the software programs [SW].

Abstract: The invention consists to propose an ultra low cost basic set top box with extension module connection possibility. Instead of proposing one STB for each market, which increase the overall costs, only one STB is marketed. In addition of this unique referenced STB, a set of modules are proposed. To connect the modules, different solutions are possible. As the high volume is based on the basis STB, the cost of the add-on module has to be very low. The solution consists in a card-edge board to board connector, where the connector is on the module, and not on the STB. As consequences the main board will only include contacts footprints. The basic STB can be defined after a marketing study and includes the needed features for High-volumes market. The customer only pays for the features he wants.
