DVBmux is a fully-featured MPEG-2 software-based multiplexer written with a DVB broadcasting environment in mind. Running under the control of a suitable Realtime Linux kernel, DVBmux may replace most overpriced hardware solutions in digital broadcasting headends or TV studios.
The design priorities of this application were reliability and performance. On decent machines DVBmux may processup to several Gbit/s of UDP-encapsulated MPEG-2 Transport Streams.
