Abstract: A system and method of multiplexing data into an MPEG transport stream are described. In particular, an IP packet is examined to determine if it is a multicast IP packet. If so, the IP packet is repackaged into one or more MPEG packets for transmission in the MPEG transport stream.

Abstract: A feature-rich transport multiplexer and a number of associated methods, systems, subsystems, software features, graphical user interfaces and control systems are disclosed. The disclosure includes GUI's that enable operators to easily monitor and manipulate content streams flowing through a transport multiplexer in real-time. The disclosed interfaces include screens that supply operators with identity, structure, configuration, bandwidth utilization and/or status information for system hardware and software. The disclosed features also provide computer assisted routing configuration for present and future routing events through simple manipulation, such as drag and drop operations, of graphical objects. Routing control is further simplified by permitting operators to configure routing control of individual content stream components as well as groups of such components simultaneously.
