There are terminal devices, also referred to as boxes, either newly installed or put back onto a system after a period of time. The system is configured to offer media services. An original library in each of such boxes is updated with the most demanded titles first or the least amount of data possible so that a box may be in condition sooner to not only fulfill orders for the most demanded titles but also provide needed data to other boxes. Depending on implementation, the updating of the original library in a box may be carried out by receiving data chunks by a gossip protocol from other boxes that collectively have the latest titles or receiving proper release packages from a service provider via a broadcasting or multicasting infrastructure.
