Virtual modem for STB network

This presents a solution to connect multiple Set-Top-Boxes (STBs) to a single telephone connection for accessing the outside network. The Direct-To-Home (DTH) network is basically data receiving only system. It is not able to send data back to the DTH provider. The paper STB requires access to the outside network for sending user requests to the DTH provider for tasks like interactive TV, On-demand services, live gaming etc and to processing payments for subscriptions, DTH charges, etc. In this approach, out of many installed STBs in a location only one STB needs to be connected to the telephone connection physically. The rest all STBs can access the telephone line virtually. This saves the effort to bring a physical telephone connection to all STBs present in a location.
