The multimedia content delivery system is a low-cost enabler for many MPEG-based applications enabling the subscribers to play multicast MPEG streams. A plurality of files with MPEG encoded multimedia content are stored at a server and streamed to the subscribers using a multithreaded processing system (or MPEG sender). The sender operates in a snoop mode or in an open loop mode. In the snoop mode, a main thread performs an IGMP snoop looking for membership reports (leave, join, change channel), and configures a plurality of sender threads based on these reports. Each sender thread transmits a multicast data stream with encoded multimedia content from a respective file to a corresponding multicast address. In the open loop mode, the sender transmits multicast data streams to all multicast addresses continuously.
