Presentation
MuMuDVB (Multi Multicast DVB) is a program for streaming TV over a network originally based on dvbstream.
MuMuDVB can redistribute a stream from a DVB source (digital satellite television, digital terrestrial television, or digital cable television) on a network, in multicast or in HTTP unicast. Its main feature is to take a whole transponder and put each channel on a different multicast group. MuMuDVB have a low memory and CPU footprint and is able to run on embedded platforms. MuMuDVB examines the contents of the transponder to find the services to stream, allowin minimal configuration work.
MuMuDVB supports CAM (hardware and software) and is able to fully decode all channels on the given transport stream.
MuMuDVB works under linux and uses the linux DVB API. It's free software, and released under the terms of the GPLv2.
Obtaining mumudvb
Mumudvb is packaged in debian. You can also get the sources and compile them yourself.
You can get the sources Here
